Factors Influencing the Spatial Variability of Air Temperature Urban Heat Island Intensity in Chinese Cities

Few studies have investigated the spatial patterns of the air temperature urban heat island(AUHI)and its controlling factors.In this study,the data generated by an urban climate model were used to investigate the spatial variations of the AUHI across China and the underlying climate and ecological drivers.A total of 355 urban clusters were used.We performed an attribution analysis of the AUHI to elucidate the mechanisms underlying its formation.The results show that the midday AUHI is negatively correlated with climate wetness(humid:0.34 K;semi-humid:0.50 K;semi-arid:0.73 K).The annual mean midnight AUHI does not show discernible spatial patterns,but is generally stronger than the midday AUHI.The urban–rural difference in convection efficiency is the largest contributor to the midday AUHI in the humid(0.32±0.09 K)and the semi-arid(0.36±0.11 K)climate zones.The release of anthropogenic heat from urban land is the dominant contributor to the midnight AUHI in all three climate zones.The rural vegetation density is the most important driver of the daytime and nighttime AUHI spatial variations.A spatial covariance analysis revealed that this vegetation influence is manifested mainly through its regulation of heat storage in rural land.

A Bi-modal Model for Chinese Cities: City Size, Car Use and Land Rent

China is experiencing rapid urbanization and motorization. Urban transport congestion poses a challenge to the cities of China. Policies have been made trying to control the car use and the land use in Chinese cities without sound modelling researches. The existing literature on monocentric city modelling has shown that the parameters are critical for the outcome of the modelling. Following the Alonso-type monocentric model, this paper introduces a bi-modal model to simulate the city size, the distribution of land rent and the modal substitution in Chinese cities. We set the key parameters according to the recent available data of China′s cities, and re-explain the hypothesis of the model. Then we make a sensitivity analysis to reveal the impacts of key parameters on the Chinese cities. According to the results, we find that the wage, the price of car use and the agriculture rent have significant impacts on city size. The land supply for the private transport or the public transport has the strongest impacts on car use and the level of transport congestion. The total population of the city and the wage level have strong impacts on land rent. Some results are counter-intuitive, but explainable. We also discuss implication of these results for policy making.

Mercury concentration in hair samples from Chinese people in coastal cities

This investigation was made to estimate current normal concentrations of total mercury in the hair of Chinese coastal people. Hair samples were collected from 659 healthy inhabitants in the areas along the coast and the rivers (such as Shanghai, Ningbo, Dalian, Xiamen, and Zhoushan) of China from Feb. 2005 to June 2006. Total mercury concentrations in the samples were analyzed by the cold vapor atomic adsorption spectrometry method (CVAAS). The results showed the geometric mean concentration of total mercur...

An Empirical Study on Chinese City Network Pattern Based on Producer Services

Globalization and informatization have accelerated city networking process over the world, which makes research on city network a hot topic in the fields of urban geography and economic geography. With Chinese economic structure adjustment and city economic growth, producer services have begun to play an increasingly important role in city-region networking. This paper employs the methodology of world city network to analyze and explain the spatial development characteristics of China's urban network system based on the data of nationwide producer services enterprise network. The research result indicated that the distribution of producer services network has a positive effect on the development of Chinese city networks. City network connectivity is closely related to the significance of city in producer services development, and the former will gradually decline with the drop of the latter. Accordingly, the 64 cities can be divided into the national central cities, regional central cities, sub-regional central cities and local central cities in accordance with their position and role in the nationwide producer services network. It is concluded that high-grade cities with quality producer services dominate the pattern of Chinese city networks and there emerges three spatial agglomerations of producer services enterprises in Changjiang (Yangtze) River Delta, Zhujiang (Pearl) River Delta and Beijing-Tianjin-Tangshan Economical Region. Moreover, the distribution of different producer services industry varies from city to city, which also affects the characteristics of network development.

Private Car Travel Characteristics and Influencing Factors in Chinese Cities——A Case Study of Guangzhou in Guangdong,China

Taking Guangzhou as a case,this paper adopted a questionnaire survey to gather first-hand data and analyzed the characteristics and influencing factors of private car travel in Chinese cities.As the research indicated,trip purposes of private car travel are mainly commute and business affairs with a more flexible trip in the urban core area.And trip intensities are concentrated in a certain extent,with trip frequency being lower in the urban core area than the peripheral area.In addition,the trip time has two significant peaks occurring in the morning and afternoon,and one trough in the midday.And trip spatial distribution is mainly within commute with both residence and employment in urban area and inward commute with residence in suburban area while employment in urban area.Both kinds of commutes direct to the urban area.The study also shows that the characteristics of private car travel are principally influenced by two aspects:travelers' attributes and urban characteristics.The main travelers' social and economic attributes influenced it include the gender,education attainment,age,driving experience and per capita monthly household income.The urban characteristics influenced it mainly cover the land use pattern,public traffic facilities and spatial attributes of residential environment.

Mass Human Migration and the Urban Heat Island during the Chinese New Year Holiday: A Case Study in Harbin City, Northeast China

Many Chinese people leave big cities for family reunions during the Chinese New Year （CNY）, which is the most important public holiday in China. However, how modem mass human migration during the CNY holiday affects the urban heat island （UHI） is still un- known. Here, the authors investigate the role of modem human migration for the UHI effects during the CNY holiday for the period of 1992-2006 in Harbin City, Northeast China. The results show that during the CNY week, the UHI effects expressed as daily mean, maxi- mum, and minimum temperature differences between urban and rural stations averaged over the period of 1992-2006 are 0.65℃ （43%）, 0.31℃ （48%）, and 1.14℃ （71%） lower than during the background period （four weeks before and four weeks after the CNY week）, re- spectively. Our findings identify previously unknown impacts of modem mass human migration on the UHI effects based on a case study in Harbin City.

Evaluation of Medical Cost Lost Due to Smoking in Chinese Cities

Smoking induces substantial diseases burden on both individual and the whole society.To identify the true smoking-attributable economic loss, we introduce medical cost accounting as a means to calculate disease-speciflc medical cost, including inpatient and outpatient cost of those diseases caused by smoking. Medical cost is defined as health fesource consumption in terms of money. Cost is allocated to departrpent and services according to coeffcient of benefit and operation time. The study in 1988 indicates that total smoking-attributable medical cost is 2.32 billion RMB Yuan in China, 1.70 billion RMB Yuan for outpatient, 0.62 billion RMB Yuan for inpatient. If indirect cost is included, the cost will be greater. Chronic obstructive emphysema has the highest proportion (55.41%) in smoking attributable medical cost

“Voices of Heaven and Rhymes of God”——My English and Chinese Poetry Written from the Bible in Rhyme and Rhythm is Worth over Fifteen Towns together

Thanks to Heavens bestow me natural gift and literary talent, so that I not only like English and Chinese poems, but also can write poems in English and Chinese. After my 2nd book English Letters and Essays published by Sichuan University Press in March 2016, I began to write my 3rd book Voices of Heaven and Rhymes of God-My English and Chinese poetry written from the Bible in Rhyme and Rhythm. Imitating the most famous British, American and Italian poets, I have written more than one thousand English and Chinese bilingual poems from free poems, prose, addresses and narratives in the nine copies of the Bible in fourteen kinds of English metrical stanzas of poems, such as couplet, tercet, quatrain, cinquain, sixain, septet, octive, Spenserian stanza, ten-line stanza, sonnet, crown sonnet and long-stanzas (12, 13, 18) in rhyme and rhythm, in iambic pentameter and iambic tetrameter. And my Chinese poems in the version are in five, six, seven, eight and nine Chinese characters. We know the story in the Spring and Autumn Dynasty, Bian He’s Jade is the Jade of jades, the Treasure of treasures, and it is worth fifteen towns together. And I think my treasury Voices of Heaven and Rhymes of God is the Gem of jades and treasures, cause it brings us proverbs, wisdom, courage, confidence, strength, lifestyle etc. from the Bible, it really brings us heavenly grace, gift and wisdom. Voices of Heaven and Rhymes of God will be submitted out respectfully to common people;its soul is praising the Heavens sincerely, and hearing a universal singing.

Measurement and influencing factors of urban traffic ecological resilience in developing countries: A case study of 31 Chinese cities

An urban traffic ecosystem is a spatial structure composed of air,population,vehicles,roads,green spaces,and regions.Traffic ecological resilience is a critical issue in high-quality urban development.From the perspective of system optimization,it is important to study the level of urban traffic ecological resilience and analyze its influencing factors.In this study,we evaluated traffic ecological resilience,characterized its spatio-temporal differentiation,and explored its influencing factors by constructing a system of urban traffic ecological resilience and by analyzing the environmental protection and urban construction data in 31 Chinese cities during 2011-2018.By conducting Kernel density analysis,standard deviation ellipse,comprehensive weight determination,panel data regression analysis,andχ2test,we found that traffic ecological resilience was low on the whole and exhibited the temporal trend of“decreasing first and then increasing”and the spatial characteristic of“high in the east,second in the middle,and low in the west”.The cities with high traffic ecological resilience density values were located in Southeast China and tended to move from northwest to southeast.Governance capability,market activity,technological innovation capability,opening degree,and financial resources had significant effects on urban traffic ecological resilience.Finally,we gave some suggestions for improving the urban traffic ecological resilience in Chinese cities as well as other developing countries in the world.

Short-term Effects of Air Pollution on Mortality in a Heavily Polluted Chinese City

Since the London fog in 1952, numerous epidemioLogical studies have revealed that both short-term and long-term exposure to air pollutants is associated with the development of diseases[1]. Up to date, the assessment of air quality on health and air quality standard establishment in developing countries were mainly relied on extrapolation based on the results from long-term cohort studies conducted in Europe and North America.

Empirical Research on the Factors of Chinese City Growth in the Transitional Period

Based on the definition of the concept of city growth, the paper mainly discussed the factors which impact the growth of Chinese cities in the transitional period by selecting the proportion of city construction land area to the area of the city X1(%), green coverage ratio of the built up area X2(%), the ratio of personnel involved in the secondary industry X3(%), the GDP per capita X4(×104)and other 43 indicators, by relying on the relevant data from China Urban Statistical Yearbook(2008), applying SPSS statistical software and by applying the Factor Analysis and Regression Analysis. The results show that the factors which affect the city growth have four major groups, namely economic and institutional factors, location factors, environmental factors and social cultural services and functions. Among the factors which affect Chinese city growth, the general budgetary expenditures and the general budgetary revenues of local public finance are the most important factors. The general budgetary expenditures of local finance, the general budgetary revenues, the lands of urban construction and other 12 factors obtained by gradually excluding method can be used to present the coefficient of city growth.

Technology Demand Assessment of Adaption of Chinese Cities to Climate Change

Climate change adaptation is the process of preparing and actively adjusting to meet the climate change (negative effects and potential opportunities). Urban adaptation is aimed at the sensitivity level of risks and specific impacts of cities under the impact of climate change, and to develop policies and investment programs to reduce the vulnerability of cities to climate change risk. Urban adaptive action provides the basis and direction for the construction of urban resilience and sustainable development. Identifying the demand of adaption technologies, promoting the practical implementation of international technology transfer and reducing domestic emissions have important significance for the global response to climate change and improvement of the ability of urban adaptation. In this paper, through in-depth analysis on the concept and connotation of climate change, climate disasters and urban adaptation to climate change, the evaluation framework and steps of urban adaptation to climate change technology are determined, and six priority application technologies which can maximize the overall efficiency of sustainable development, improve the ability to adapt to climate change and at the same time reduce the cost at the greatest extent are identified.

Gary Snyder＇s Defamiliarization Translation of Chinese Classic Poems

The ＂defamiliarization theory＂ has undergone a process of continuous improvement, with its focus shifting from the plain text to the world concerned. A similar process was experienced by scholars who apply the theory. In this paper, the author explores Gary Snyder＇s ＂defamiliarization＂ technique of translating classic Chinese poems Departing from the traditional critique of the form and structure of the text, the author applies the ＂defamiliarization theory＂ itself towards the understanding of Snyder＇s art and thinking and a discussion of his literature, ideology, and creativity, thereby restoring a true image of Gary Snyder as a poet and a translator

Evaluation of urban green development of typical Chinese cities

The goal of this work was to evaluate China's urban green development. Ten typical cities belonging to four types were chosen as case studies: Beijing, Shanghai, Suzhou, Wuxi, Nanjing, Xi'an, Wuhan, Nanning, Weihai and Yichang. We used the CLD model from system dynamics to analyze the complex relationships between various elements of city development, including resources and environmental conditions, degree of social development, economic development and administrative capacity. These four elements—environmental, social, economic, and administrative—were used to build a green development assessment framework for Chinese cities. Upon building the evaluation system, 47 evaluation indicators were chosen. The results show that the comprehensive values for green development in these ten representative cities were all low, meaning that there is a large gap between urban development and green sustainable development. Many aspects of green development need to be substantially enhanced, such as governing environmental problems, alleviating resource pressures, enhancing economic efficiency, and increasing the green economy.

The Travelling Muse Cathay and the Influence of Chinese Classical Poems on Ezra Pound＇s Poetics＊

This paper intends to study Ezra Pound＇s early poetics and his modemist poetry through a close research of the Eastern elements in the shaping process of his poetics and the significance and influence of his poetic thoughts on the American New Poetry Movement. In order to clarify the essence of Pound＇s early poetics under the influence of Chinese classical poems, the paper starts from the discussion of the influence of Cathay （1915） and his translation of Cathay; then it provides a detailed analysis of the relationship between Chinese classical poems and Pound＇s creation; and finally it has given an analysis of ＂In a Station of the Metro＂. Pound absorbed different poetic concepts from all of them and transformed his poetry from the conventional Romanticism to the innovative Modemism. What Pound innovated in the poetry composition is of great importance if the new era wishes to shake off the banality and out-of-date tradition in literature. Pound changed a whole generation of poets and set a good example for those who desire to write in a new way
