新化—城步地区泥盆纪沉积相及台盆演化

新化—城步地区泥盆纪沉积相类型较丰富,可划分7个相组、17个相。最突出的特征是在两个碳酸盐台地之间发育有一较深水的盆地,即台盆。西部的碳酸盐台地与台盆之间的边缘无明显的陡坡,属于J.F.Read所称的碳酸盐等斜缓坡。区内沉积相,尤其是在棋梓桥晚期——佘田桥期,大体上呈北北东向展布。构成这一特殊沉积格局的主要原因是该区沉积相受加里东运动期间形成的基底断裂控制。区内台盆演化可分为初始台盆、台盆扩展、台盆稳定、台盆最大扩展、台盆收缩变浅、台盆残余凹陷等六个阶段。

Fission Track Dating of Authigenic Quartz in Red Weathering Crusts of Carbonate Rocks in Guizhou Province

The Cenozoic evolution history of Guizhou Province, which is located on the southeastern flank of the Qinghai-Tibet Plateau, is unclear because of the lack of sedimentation records. The red weathering crusts widespread on the Yunnan-Guizhou Plateau may bear critical information about their evolution history. This work firstly determined the ages of four red weathering crusts in eastern, central and northern Guizhou. The material used in fission track dating is well-crystallized quartz occurring in many in-situ weathering crusts of carbonate rocks. The results showed that the fission track ages of quartz vary over a wide range from 1 to 25 Ma in the four profiles, significantly younger than the ages of the Triassic and Cambrian parent rocks. In combination with the evolution history of the regional geology during the period from 25 to 1 Ma, the ages of quartz can exclude the possibility that the origin of quartz has nothing to do with primary clastic minerals in parent rocks, authigenesis during diagenesis and hydrothermal precipitation or roplacement by volcanic activities. It is deduced that the well-crystallized quartz was precipitated from Si-rich weathering fluids during the weathering process of carbonate rocks. The recorded ages of quartz from the four profiles are consistent with the episodes of the planation surfaces on the Qinghai-Tibet Plateau, the forming stages of red soil in the tropics of South China, the tectonically stable periods in Guizhou, and the ages of weathering in other parts of the world during the Cenozoic era. That is to say, the ages of authigenic quartz dated by the fission track method are well feasible and credible.

Temporal and spatial differences and imbalance of China's urbanization development during 1950-2006

A better understanding of the regional disparity and imbalance characteristics of China's urbanization development is the important premise for constituting correct policy and strategy and promoting the healthy and sustainable development of urbanization in the 21st century. The regional differences of China's urbanization level have close relations with natural conditions of landform and climate etc.,the urbanization level reduces with the eleva-tion of topography and decrease of precipitation. According to the statistical data set of ur-banization in 1950-2006,the temporal change course of inter-provincial disparity of Chinese urbanization level since the founding of New China in 1949 was studied,and then the inter-regional and intra-regional disparities of urbanization development were analyzed by the Theil index and its nested decomposition method,to grasp the dynamic change of spatial disparities of China's urbanization level on the whole. Using the imbalance index model,the imbalance status of urban population distribution relative to total population,grain output,total agricultural output value,gross output value of industry,tertiary industrial output value as well as gross regional product was discussed,to hold the balance characteristics of urbanization development relative to the regional development conditions from the macroscopic scales.

A Comparative Study on the Street Space Form in the Old City of Beijing: A Case Study of Shijia Hutong, the White Stupa Temple Area, and Dashilanr

EVOLUTION OF URBAN SYSTEM IN NEW ECONOMIC CIRCUMSTANCES AND PLANNING COUNTERMEASURES

Urban system is the spatial reflection of the inner-deep social economic movement. New economic circumstances not only make the evolution of urban system present one brand-new landscape, but also put forward a new subject for planning of urban system. This article analyzes the properties of the traditional economic process and its essential effect on urban system; it makes a complete survey on the properties of new economic circumstances and its effect on re-forming of urban system; the complicated influential process and result are concluded into the aspects, such as new growth motive force, new economic organization, new location factor and new spatial phenomenon, and its inner effect mechanism in shown as well. In this article, the change process of urban system space is explained in four aspects: (1) dissimulation in the process of spatial agglomeration and diffusion; (2) change of “center-periphery” effect; (3) acceleration growth of axial regions; (4) re-forming of the world and regional urban system. Based on the above theoretical analysis and the properties & requests of new economic circumstances, this article finally puts forward four philosophies emphasized by urban system planning, and forms the new frame for drawing-up of urban system planning.

New species of the diaspidid genus Lepidosaphes （Hemiptera： diaspididae） on cypress from Tibet of China

Cypress plays an important role in urban afforestation in Tibet of China, and scale insects are a serious pest group that attack Cypress. In this paper, a new species, Lepidosaphes xizangensis Feng, sp. n. from Tibet, is described. Its damages to cypress trees are recorded. The new species is similar to Lepidosaphes pineti Borchsenius, 1958, with its perivulvar disc pores arranging in eight groups, but can be distinguished from the latter by the following characteristics： （1） gland spines between median lobes longer than median lobes; （2） distance between median lobes similar than width of median lobes; （3） dorsal gland ducts are much more slender. It enriches the diversity of Lepidosaphes fauna of China and adds new information of coccids＇ damages to cypress.

An Innovative City： Impact of Innovations on City Development

The process of innovative development is stimulated by cities as centers of accumulated （regional） growth and innovative enterprises as elements of urban space. Cities stimulate innovations by creating a specific demand for innovations and innovative products as well as specific incentives such as preferable conditions for creation, accumulation, usage, and exchange of knowledge and information. Diffusion of ideas has an impact on changes in environment resulting in increase in dynamics of innovation, which means possibilities of innovative development for local firms. The paper highlights the idea of an innovative city with respect to the impact of innovations on city development. The concept of an innovative city is not clearly defined because the interpretation of innovation is differentiated and ambiguous except for common denominator of the novelty. The paper underlines the role of city＇s environment for innovations＇ creation acting as an incubator for clusters of firms, particularly those engaged in the process of high-tech involvement （technology parks）. The option of an innovative city approach presented here is the author＇s view on an innovative city＇s growth and it is based on the role of synergic interaction between innovative firms as elements of a city space and an innovative city itself.

Reflection on Enterprise Standardization Innovation under New Circumstances

Nowadays with the developmental theme of ＂knowledge economy and information network＂, technical standards increasingly become a vital means of the economic globalization competition. In the global market strategy of ＂whoever sets standards wins the market＂, it is the technological leaders that as relevant standards developers take the initiative on the world market. Therefore, from mainly addressing the universality and interoperatability of product parts in the past, technical standards have been respected as the new technical concept and gradually become the commanding height of the industry competition.

Transfrom Construction Waste into Resources

THE almost two-meter-high sculpture Liu Xiaofan admired at an exhibition,and which he assumed was bronze,turned out to have been made from recycled building waste.Liu immediately thought of the pile of demolition debris next to his home.He had witnessed new construction waste steadily piling up next to his apartment building and the community public lawn.Dust floated high and free as the wind blew and deposited it on his balcony.This epitomizes the "metabolism" of Chinese cities.

Strategic and Organizational Evolutions of High-Tech SME on Global Market

The ＂OLI paradigm＂ of Dunning （1977） claims that firm internationalization is addressed toward the exploitation of home-based specific advantages. However, evidence shows that SMEs are increasingly internationalizing their activities in order to enrich their resource pool. In this regard, a reinterpretation of the OLI paradigm came out with a new perspective suggesting that ＂foreign direct investmenf＇ （FDI） is increasingly oriented toward asset augmentation. Correspondingly, the purpose of this theoretical paper is to suggest a set of principles that could inform on how global small and medium-sized enterprises grow in the international marketplace when investing abroad.

Could Innovation be Driven by Globalization？

This paper examines the critical role of globalization as a driver for innovation. The introduction of the global strategy quadruple model truly links the three known strategy perspectives （namely, industry competition, resources and institution views） and performance. The model could assist in advancing the cause of sustainable competitive advantages. This study could assist scholars in addressing the three important research questions： （1） Why are some finns more innovative than others？ （2） What effects do product, firm, industry, and market innovativeness have on business performance？ and （3） Does the link between innovativeness and business performance depend on all or some of the innovativeness factors of product, firm, industry, and market？ The presented set of four hypotheses, when tested, will result in a better understanding of the links and relationships among a firm＇s global strategy, innovativeness, and business performance. The quadruple model presented can be used to examine these relationships in general and in the context of innovation. It is anticipated that this paper will assist researchers, business management, and analysts in developing global innovation strategies.

This article from the perspective ofintergenerational transfer of migrant workers poverty, social assistance as the breakthrough point, through the transfer phenomenon and social relief situation of migrant workers in poverty from generation to generation, according to international advanced experience put forward the blocking of migrant workers in the intergenerational transmission of poverty.

The new economy of nature:can carbon pay for nature conservation? The case of the Hong Kong Country Parks

The Country Parks of Hong Kong occupy 40%of the total landmass of Hong Kong,and consists of vast areas of secondary woodlands,scrublands,grasslands,and reservoirs.That vegetation-and the soil underneathsubtract carbon from the atmosphere,which has a market value.The aim of this paper is to estimate the value of that carbon,to assess whether that value would be sufficient to pay for the upkeep of the Country Parks,and to compare that value to the costs of alternative ways to reduce atmospheric carbon dioxide.To do this,we compare the land cover of 1978,1991,1997 and 2004 using remote sensing,and identify the three predominant land covers(woodlands,scrublands,grasslands) .We then estimate the amount and value of the carbon sequestered by the vegetation and soil of the Country Parks,and compare it to the budget available to the Agriculture,Fisheries and Conservation Department to run the Country Parks(HK$234 million in 2009/2010) .We extrapolate our results over 50 years,from 1978 to 2028.We conclude that by 2028 the carbon sequestered would be valued over HK$800 million,but the value of the additional carbon subtracted yearly would only cover approximately 7%of the total budget needed to run the Country Parks.We also conclude that because of the large budget allocated to the Country Parks,alternative methods of carbon sequestration-represented by the EU ETS price of carbon-are much cheaper.

Development of Urban Agglomerations of the Republic of Kazakhstan in Conditions of the Formation of the New Silk Road

The paper deals with current issues of the regional spatial organization based on the identification and analysis of key factors and prerequisites for the formation of urban agglomerations as the most important growth centers, integrated with global and regional markets in the conditions of a qualitatively new stage in the history of the Great Silk Road. We assess promising directions and negative effects of development of agglomerated formations and zones of their influence in the Republic of Kazakhstan as a region having an advantageous geostrategic position in the Eurasian space. In Kazakhstan, the current process of urbanization has a multiple- vector nature, and the course of formation of urban agglomerations provides convincing evidence of an increase in their share in settlement and in the total population. It is agglomerated forms of urban development that are a kind of indicator of the onset of maturity in settlement, specifying key points of the socio-economic space, namely： cores of regions, nodes of foreign economic relations and contacts, main areas of new territories development, the most important links in the internal infrastructure, etc. It is urban agglomerations that should act as a kind of special platform of integration processes, on the basis of which the Republic of Kazakhstan should revive its historical role in the development of the global project ＂New Silk Road＂ and become a major trade and logistics, finance and business, innovation and technology, and tourism hub of the Central Asia region, a bridge between Europe and Asia.

Simulating the Impacts of the New-type Urbanization Policy on Rural Settlement Changes:A Case Study in Dingzhou,China

To cope with the difficulties of integrating migrant workers into urban life and inefficient land use caused by conventional urbanization,China has proposed a new type of urbanization policy.This policy may have a significant impact on the spatial patterns of rural settlements in China.Exploring this potential impact is conducive to the proposal of scientific plans for the spatial patterns of rural settlements.Therefore,this paper chooses Dingzhou,one of the pilot cities of this new-type urbanization,as the research area to carry out a simulation study on the impact of the new-type urbanization policy.Dingzhou has invested heavily in the new-type urbanization construction in recent years,but the influence of the policy on rural settlements remains unclear.Based on the theoretical framework of previous studies,this paper set up three scenarios,namely“conventional urbanization”,“new-type urbanization”,and“counter-urbanization”.This paper used FLUS(Future Land Use Simulation)Model and various spatial data to simulate the spatial patterns of rural settlements in Dingzhou in 2030 under the different scenarios.By comparing the different scenarios,the impacts of the new-type urbanization policy on the spatial patterns of rural settlements in Dingzhou were evaluated.The results indicated that:(1)From 2000 to 2015,the area of rural settlements in Dingzhou increased by 11.12%.Spatially,the density of rural settlements around the cities and towns increased,and rural settlement areas were mainly converted from cultivated land.Rural settlements were mainly transformed into urban land and cultivated land.(2)The overall simulation accuracy of FLUS was 0.89,so it can be well applied to the simulation of rural settlements.(3)In all three scenarios,rural settlements expanded along their edges,and the closer they were to towns,the more obvious the expansion was.In the counter-urbanization scenario,the change of rural settlements was most dramatic.(4)The new-type urbanization policy makes the spatial patterns of rural settlements in Dingzhou more stable and more intensive.
