夏鲧死因再探

夏鲧是中国古代颇具争议的神话历史人物,在传统儒家主流文化体系中,他是恶名昭著的"四凶"之一,而在神话传说和其它文献记载中,他又是治水未成身先死的悲剧英雄,历代对夏鲧死因的争论虽绵延不绝却又莫衷一是。本文从历代关于夏鲧死因的几种主要观点的分析入手,结合"夏鲧作城"的文献记载,将夏鲧置身于氏族社会向文明时代过渡的时代背景之下,探讨其被杀的深层原因,重新确立其作为时代先行者和治水英雄的历史文化地位。

Phosphorus Balance in the Main Crop Production Systems in Beijing Suburb——Case in Shunyi District

[Objective] The research aimed to evaluate the phosphorus balances in the main crop production systems in Shunyi District of Beijing City.[Method] By using the nutrient budget method,the phosphorus balances in the main crop production systems（field crops,orchard and open-field vegetables） in Shunyi District of Beijing City were evaluated.Moreover,the main influence elements of phosphorus surplus in the farmland were analyzed.[Result] The positive phosphorus balances were found across all three crop production systems in the study period.The amount of phosphorus surplus [491.8 kg/（hm2·a）] in vegetables production system was significantly higher than that in field crops [82.7 kg/（hm2·a）] and orchard [129.5 kg/（hm2·a）] production systems（P0.05）.But the amount of phosphorus surplus between the latter two had no significant difference（P0.05）.Phosphorus surpluses in the production systems of field crops and vegetables respectively presented the extremely significant and positive relationship with the phosphorus input from chemical fertilizer and organic fertilizer（r was respectively 0.987 7 and 0.970 1）.The phosphorus input from chemical fertilizer and organic fertilizer in the orchard production system both presented the extremely significant and positive relationship with the phosphorus surplus in the farmland（r was respectively 0.836 3 and 0.625 2）.However,the phosphorus harvested by crops didn＇t significantly correlated to the phosphorus surplus in the farmland for all three crop production systems（P0.05）.[Conclusion] The risk of phosphorus pollution potential in all three crop production system of Shunyi Distirct was high,especially in the vegetable production system.The phosphorus surpluses in the production systems of field crops and vegetables were mainly from the inputs of chemical fertilizer and organic fertilizer,respectively.However,the inputs of chemical fertilizer and organic fertilizer both significantly affected the phosphorus surplus in the orchard production system.

Characteristics of produced water during coalbed methane （CBM） development and its feasibility as irrigation water in Jincheng, China

Water resources are scarce in Jincheng. Huge quantities of water are pumped out in the dewatering course, and the disposal of CBM water is one of the most important problems during the extracting of CBM. Based on the data of CBM water production, chemical characteristics, the irrigational conditions for major crops, and China irrigation water standard, the feasibility of CBM water as irrigation water is discussed. The result shows the CBM water quality doesn＇t fully meet irrigation water quality standards in Jincheng, its high salinity and sodium adsorption ratio （SAR） in CBM water might affect crops growth and lead to yield loss, and can＇t be used as irrigation water directly, but with the treatment of the reverse osmosis （RO） to lower the salinity and SAR of CBM water, the CBM water can be used as irrigation water.

Spatio-temporal Analysis of Urban Spatial Interaction in Globalizing China—A Case Study of Beijing-Shanghai Corridor

This paper aims to explore urban geography with a new perspective. Endowed with the urban geography connotations, an improved data field model is employed to integrate temporal dimension into spatial process of cities in a typical region in this article. Taking the Beijing-Shanghai Corridor including 18 cities as an example, the authors chose the city centricity index (CCI) and the spatial data field model to analyze the evolution process and features of sub-region and urban spatial interaction in this corridor based on the data of 1991, 1996 and 2002. Through the analy- sis, we found that: 1) with the improvement of the urbanization level and the development of urban economy, the cit- ies’ CCI grew, the urban spatial radiative potential enhanced and the radiative range expanded gradually, which reflects the urban spatial interaction’s intensity has been increasing greatly; 2) although the spatial interaction intensity among the cities and sub-regions in the Beijing-Shanghai Corridor was growing constantly, the gap of the spatial interaction strength among different cities and sub-regions was widening, and the spatial division between the developed areas and the less developed areas was obvious; and 3) the intensity of the spatial interaction of Beijing, Shanghai and their urban agglomerations was far greater than that in small cities of other parts of the corridor, and it may have a strong drive force on the choice of spatial location of the economic activities.

Evolution of Jobs-housing Spatial Relationship in Beijing Metropolitan Area:A Job Accessibility Perspective

With the urban expansion and economic restructuring, the jobs-housing relationship has become an important issue in studies on urban spatial structure. This paper employed a job accessibility model, which is an evaluation instrument to measure the jobs-housing relationship in Beijing Metropolitan Area from a job accessibility perspective. The results indicate that the population in the central city is declining, whereas the population in the suburbs is consistently growing and forming new population centers. However, the distribution pattern of employment is still highly centralized. Job accessibility varies in different locations, but the inner-city areas(within the Third Ring road) have seen improved job accessibility over time while job accessibility in the suburbs(especially outside the Fourth Ring road) has decreased, and this has led it to become a primary area of residential and employment mismatch. At the same time, the new towns in the outer suburbs have not yet demonstrated great potential to attract more jobs. In addition we find that, to some extent, urban planning changes the jobs-housing relationship, but a polycentric urban spatial structure is not yet evident. The floating population and related housing policy also affect the jobs-housing relationship. We propose some measures to resolve the spatial mismatch as well as some future research directions.

Paired Border Towns or TwinCities from Finland and China

This paper discusses cross-border cooperation at the level of urban socio-economic systems. Worldwide, cross-border urban cooperation has in several cases produced socio-economic and political coherence supported by various joint programs and efforts. However, the degree of coherence varies and seldom cre-ates socio-economically and politically tightly integrated "Twin-Cities" where the state border becomes highly transparent or ob-scure. Focusing on Finlan d and China, our aim is to identify whether the selected border towns represent coherent TwinCities or a more loose type of "paired border towns". The study uses an empirical examination of three Finnish towns (Helsinki, Tornio, Imatra) and their neighboring towns in Estonia, Sweden, and Rus-sia as a benchmark. Then, a comparative study is made regarding three Chinese cross-border cities facing Russia, Vietnam and Ka-zakhstan. We highlight the differences in cross-border integration from the viewpoint of shared public sector programs, cross-border enterprise relocation and networking, and integrated social sector in terms of labor market, education and shopping area.

Monomer Migration and Annihilation Processes

We propose a two-species monomer migration-annihilation model, in which monomer migration reactions occur between any two aggregates of the same species and monomer annihilation reactions occur between two different species. Based on the mean-field rate equations, we investigate the evolution behaviors of the processes. For the case with an annihilation rate kernel proportional to the sizes of the reactants, the aggregation size distribution of either species approaches the modified scaling form in the symmetrical initial case, while for the asymmetrical initial case the heavy species with a large initial data scales according to the conventional form and the light one does not scale. Moreover,at most one species can survive finally. For the case with aconstant annihilation rate kernel, both species may scale according to the conventional scaling law in the symmetrical case and survive together at the end.

Sojourners in Time： Revisiting Thornton Wilder＇s The Happy Journey to Trenton and Camden

Thornton Wilder＇s works are often characterized as transcending time. Our Town （1938） remains a widely produced piece of dramatic literature nearly 75 years after winning the Pulitzer Prize in 1938. However, many of Wilder＇s one-act plays are less well-known and subsequently are less often produced. The Happy Journey to Trenton and Camden （193 l） predates Our Town （1938） and yet is written in a similar style, utilizes the stage manager motif, and reflects upon issues of life and death found in Our Town （1938）, The Bridges of San Luis Rey （1927） and many other of Wilder＇s works. ＂Sojourners in Time＂ reflects upon the time period and place in Wilder＇s one-acts within the context of a contemporary journey in order to determine what, if any, aspects of this piece translate to current times.

Japanese Cooperation for Urban Planning in the Old Capital of Damascus

Historic cities are cultural achievements that are gradually created by inhabitants over the centuries. In developed countries, the conservation of historic cities seems to be generally acknowledged as a method of community development that does not depend on huge exploitation. On the other hand, no sufficient countermeasures have been taken in developing countries because most native stakeholders are still interested in development. Here the author could focus on so-called ＂international cooperation＂, but urban conservation for historic cities where inhabitants actually live is still a minor consideration except for some government-based conservation projects for monuments and isolated examples of cultural heritage. In this paper, the example was taken of a conservation project which has been carried out by JICA （Japanese International Cooperation Agency） in Damascus, the old capital of Syria. The target area for the project is ＂Qanawat South＂. Although the origin of＂Qanawat South＂ dates back to the Roman age, efforts for urban conservation have not been well organized, partly because the area is located outside of the so-called old city registered as a world heritage site. For example, the master plan of 1968 indicated the redistribution of the traditional quarters, while some conservation laws have been restricting the regeneration of the area. Moreover, there is not yet any consensus among the stakeholders concerning the historical value of the quarter, they are still questioning why the area should be conserved rather than being freely sold or developed and what and how they should contribute to conservation. Based on analysis of the actual situation of Qasr al-Hajjaj Street, this paper examines a method called ＂restoration-type＂ facade improvement adopted by JICA, for which the final goal is not only to maintain the appearance of the street but also to activate the life of the habitants of the street.

The Everyday （in） Urbanism： What＇s New on the Spot

The paper aims at measuring the influence that the everyday theme has exercised in the formation of the idea of space that is permeating the thought of many contemporary urban planners. Through the investigation of two recent approaches, the Italian and the American ones, the complex relationships between daily practices and urban spaces, in the continuous redefinition of the concepts of public and private sphere, are described. In this context, the Everyday Urbanists＇ work had the merit to reveal and investigate the social possibilities offered by the patterns of everyday life. They were among the first to speak about a citizenship redefinition, process which has been increasingly debated by many scholars. Citizenship is thus turning to be less formal, while becoming more substantive and insurgent. The paper demonstrates that, according to this crucial change, new and meaningful relations between citizenship and planning can be established and that these are able to open planning practice up to the present ethnographical possibilities of the urban space, and to its tactical and polysemic dimensions.

Cooling effect of urban parks and their relationship with urban heat islands

It is claimed that open spaces in cities, such as parks, have an urban cooling effect. However, the relationship between urban parks and adjacent districts is still not explicit. In order to clarify the interaction between urban parks and their urban surroundings, this paper takes the Temple of Heaven Park （THP） as an example of a park station and focuses on analyzing the differences with a nearby urban station.THP is located in the center of Beijing, and the nearest urban station is Tian An Men. It is interesting that the cooling effect of THP reaches a peak and remains stable when its city background urban heat island （UHI） varies within a given range, but becomes unstable when the UHI goes beyond the range. This is called an enhanced cooling effect in this paper. As a result, the UHi intensities （UHIIs） are calculated in order to comprehend the role of the park cooling effect in the urban heating characteristics of Beijing. By comparison with five other park-district pairs, this paper attempts to identify the causes of the enhanced cooling effect. It is found that six park-district pairs consistently demonstrate a persistently stronger cooling rate during the night, and that the water coverage might be a key factor in enhancing the park cooling effect. Based on further investigation of the influence of surrounding UHIs on the park cooling effect, it is found that the UHII differences in park-district pairs show quasi-linear changes within a given range as the UHli of the surrounding district increases.

The Two Faces of Urbanity： Exploring Global and Local Values---Two Urban Studios in Taksim Square and along the Shores of the Golden Horn in Istanbul

Since the 18th century, the irritating but also fascinating scenes of urbanity--a complex phenomenon with cultural, social, political, economic, temporal, spatial, functional, and formal dimensions--have been described in literary works. Many seemingly opposite facts, such as individuality/society, freedom/loneliness/socialization, anonymity/strangeness/identity/belonging, diversity/chaos/segregation, indifferent city-dweller/initiative citizenship, have been revealed through literary works, travel and utopian writing, urban theories, scientific studies, manifestos, and newspaper articles. On the one hand, there are those who advocate a life outside the city because they consider the problems produced by the city and the phenomenon of density which they perceive merely in quantitative terms, as unsolvable problems. On the other hand, there are those who see the production of loose urban fabric as a solution or those who accept the （seemingly） opposite facts of urbanity as positive values and therefore support city life. All of these ideas are still as actual today as they were in the past. We are often unable to use our citizen rights to the city, to encounter different classes （social/etlmic/religious）, to experience heterogeneity as an aspect inherent in city life and in the route of our daily life--following the orders of the capitalist system mainly organized around work--and we are often drawn into the same districts on the same paths. Our perception of our urban environments may get monotonous and shallow, but the irritating yet fascinating features of the first big cities still exist and may be grasped and brought into consciousness. Throughout their architectural education, especially in urban design studios, students can be encouraged to investigate the rhythm of their daily life, the conditions of their urban environments, and discovering the city as an intellectual and sensual programme, so that the phenomenon of urbanity can be grasped not just on formal, but on various other dimensions as well. This study focuses on the process and outcomes of two urban studios located in Taksim Square and along the shores of the Golden Horn in Istanhul. Taking the multidimensional content of urbanity into account, acquired theoretically through literary works and studies on urban planning and its history, the main aim of these studios has been the phenomenological understanding of the dynamic content of urbanity by the students. Through creative analysis of permanent/temporary spaces engendered by the diversity of user profiles and actions discovered on phenomenological excursions, students examine the qualitative values of density and global and local dynamics. We believe that designing spaces as ＂prototypes＂ helps highlight the multidimensional content of urbanity. The present study aims not only to highlight the multidimensional content of urbanity, but also to encourage its discussion in architectural design education and to emphasize the positive contribution of theoretical readings and phenomenological studies to urban design studios. The present study also aims to emphasize the beneficial correlation of global and local dynamics as the two faces of urbanity; important more than ever for the big cities of the 21 st century if we advocate for a vivid and resilient city life and citizens.

Spatial Interaction and Network Structure Evolvement of Cities in Terms of China's Rail Passenger Flows

Cities separated in space are connected together by spatial interaction (SI) between them. But the studies focusing on the SI are relatively few in China mainly because of the scarcity of data. This paper deals with the SI in terms of rail passenger flows, which is an important aspect of the network structure of urban agglomeration. By using a data set consisting of rail O-D (origin-destination) passenger flows among nearly 200 cities, intercity rail distance O-D matrixes, and some other indices, it is found that the attenuating tendency of rail passenger is obvious. And by the analysis on dominant flows and spatial structure of flows, we find that passenger flows have a trend of polarizing to hubs while the linkages between hubs upgrade. However, the gravity model reveals an overall picture of convergence process over time which is not in our expectation of integration process in the framework of globalization and economic integration. Some driven factors for the re-organization process of the structure of urban agglomeration, such as technique advance, globalization, etc. are discussed further based on the results we obtained.

The Idea of ＂Architecture Stage＂： A Non-material Architecture Theory

The purpose of this study is to find ＂the new theory＂ in the process of having quality ＂form＂ in architecture field which is usually visualized by the ruler through his ideology of his architectural work which is created by his architects. The study is about an urban design in architectural field related with space-power-knowledge. To reveal the meaning of the architecture objects is need to analyze the architectural object ＂form＂ as the culture-material, and to reveal the meaning of the objects through the hidden things related to the presence of the metaphysical data. To find ＂the new theory＂ used ＂grounded theory research＂, the method is part of qualitative research which refers to Glaser and Strauss. The achievement study is finding the idea of＂architecture stage＂ of the ruler, represented by Soekamo as the first Indonesian President. Through visual observation and spatial experiences in his several architectural works concerning the ＂Project＇s Lighthouse＂ as his architectural work in Jakarta in the 1960s the idea of connectedness was found. He composes his architecture＇s work by inserted the ＂architecture drama analogy＂ as metaphor for representing himself and his ideologist by exploring the Javanese Ancient＇s as the basic design in the modem architecture at that time the east meet west.

From Industrial Heritage to a Regional Development Core in the 20th Century： The Case of Ilha Solteira

The article deals with the built experience by the CESP （Sao Paulo＇s Electricity Company） in Urubupunga Complex, during 1950s and 1960s, with concomitant construction of urban centers--an provisional in Jupih and another permanent in llha Solteira--with accommodation for singles, working villages and residences for technicians and engineers. The city of Ilha Solteira implanted permanently was an intermediate form of organization between the camp of Jupia and the structure of a city, with a slightly more open community in which the citizens were still quite protected by the company. This study aims to describe the planning and the process of opening the core of Ilha Solteira, through non participant observation field work and research literature on the topic of its conversion into town and the attempt to create a pole of development for the region through their characteristic urban design plan： linear city and radio concentric city. However, the transformation of Ilha Solteira on a city in the early 1980s happened in the crisis of developmentalism and authoritarianism, in a time when the CESP no longer wished to transform Ilha Solteira in pole of regional development, but in a city able to stand alone, because their maintenance costs become prohibitive.

Collaborating Against AIDS:A Urban Chinese Case Study of World AIDS Day Awareness

Objective: To incorporate students and other local community partners in creating a collaborative Nanjing World AIDS Day exhibition. Background: Stigma and discrimination continue to complicate effective World AIDS Day activities in China. Including foreign students in World AIDS Day campaigns broadens the potential Chinese audience as well as making the government's AIDS policiesmore transparent. Methods: In order to broaden the potential audience, relevant media (television, radio, newspaper) were notified of the 2003 Nanjing World AIDS Day Exhibition. The exhibition represented a unique collaboration between Nanjing University and the Chinese National Center for STD and Leprosy Control, depending on foreign and Chinese students at several levels. In addition, close contacts at the Jiangsu Provincial Health Bureau helped to coordinate local experts and distribution of condoms. Results: This multi-disciplinary cooperative exhibition was successfully completed. Several major media sources covered the event. Conclusions: The success of this campaign suggests that other urban cities with significant foreign student populations could benefit from including foreign and Chinese students in future World AIDS Day campaign activities.
