Urban Design Strategy Research Based on the Concept of Sponge City: A Case Study of Renbei District in Chengdu

Cities are currently confronted with many urban problems, such as water shortages, water quality pollution, floods, and the loss of habitats of aquatic organisms, and badly in need of a more comprehensive solution. In this context, the concept of "sponge city" is proposed. This paper, based on the theory of sponge city and low impact development, elaborated the origin, development, connotation, and construction method of "sponge city" concept. In this paper, the urban design scheme of Renbei District in Chengdu was taken for example to analyze the geographical environment and climate characteristics of Chengdu and explain the formation and verification of the scheme. It is considered that the "sponge city" is different from the traditional urban infrastructure. It is essentially an ecological approach. Its core is to build a cross-scale urban water ecological infrastructure to comprehensively solve the prominent water-related problems of urban and rural areas in China.

长沙市土地利用生态风险及评价

摘要：城市生态环境问题已成为制约城市可持续发展的重要问题,土地利用变化是城市生态环境改变的重要因素。长沙市作为中部经济发达、人口众多的大城市,其工业化和城市化的发展速度很快。强烈的土地需求对土地利用的强度、方式、规模、布局等造成了深远的影响,同时也对城市生态环境造成强烈的冲击,生态安全受到严重威胁。本文引入城市土地利用生态风险评价的概念,分析长沙市土地利用现状,阐述城市土地利用生态风险产生的原因,识别与土地利用相关的生态环境问题,综合运用主成分分析,K均值聚类等方法,建立了土地利用生态风险评价模型,分析和评价长沙市土地利用生态风险。结果发现该区所研究时段土地利用生态风险总体上变大,土地利用生态风险值从1996年的-0.85286（Ⅴ）,变为2006年的1.321039（Ⅰ）,期间变化波动明显,风险值在1996-1999年和2003-2006年趋于上升,2000-2002年趋于下降。根据此评价结论提出一系列规避和应对生态风险,协调城市土地利用与生态环境的对策。     

Environment Principle in the City Illumination

Through the analysis on components of the environment,the essential factors affecting the city illumination,such as human beings,light and objects,are discussed in this paper with the help of environment psychology.On the basis of people's visual characteristics and psychological needs,the characters of illumination of the city in whole,city square,buildings and garden landscape are summarized and the laws of city illumination are revealed.It is found that designing the city illumination should create not only a visual environment but coordination with city spatial elements and physiological sense of human beings,offering a psychological environment in harmony with function atmosphere.The author finally puts forward his thinking on city illumination which combines the natural condition,object form,people's visual characteristics and environmental features based on the environment principle.

GARDEN CITY,GREEN CORE CITY AND ECOLOGICAL CITY

Starting from the fact of contemporary urban problemsexsiting universally,this paper traces back and analyses the theoreticalpoints of green city and its widespread and profound influence.Thispaper also expounds its benefit and enlightenment to us.To relax thesevere urban ecological and environmental problems,the author,consci-entiously drawing some modern urban planning thoughts such as gardencity,organic dispersion and systematical coordination and based on thepractice in the over all planning of Leshan city,presents a new conceptof green core city aiming to combine overall city planning with ecologyplanning and layout structure with improving urban living quality bylaying the city in several natural ecological circles.It will creat a higher urban living environmental quality.To satisfy demand of contemporarycities on a higher stage of development for environmental quality,it isnecessary to achieve the developmental goal of ecological city.This paperstates this point of veiws on the meaning and basic requirements for anecological city and stresses that it is important to raise the view ofunifying economical and social benefits with ecology and environment inurban planning and construction.     

Exploring Harmonious Protection of Land Resources in City Construction

Urbanization in China is at an essential point in its transformation from the initial stage to accelerating stage. With quick expansion of city scale and large occupation of land for urban construction, the contradiction between land resource shortage and people's living needs becomes more and more prominent. It has great affection on the grand plan of China's sustainable development of economy and society. How to adjust the relations between the development of urban construction and protect the land resource, promote the rational use of urban land, perfect and complete the protection system of land resource for improving the efficiency of urban land use. In order to conserve land resource and find a sustainable way for development of people's living and environment construction, the above mentioned problems are the most important issue for urban construction and important subject of this paper.     

The Research on the Capacity Mechanism of City Space Expanding and Its Ecological Model

In the period of the city space expanding with the high speed, the theories system used to explain the city space is not perfect in our country. It is lack to expand this mechanism, among them research ecosystem' s main factors to particularly should be enhanced, especially the ecological factor. With rational analysis, the paper puts forward the viewpoint that the urban space is in ecological changing period, and considers that the power affecting the urban space expand involves motivity and resistance. Building the corresponding ecological model helps to cognize the city development roundly with ecological model constructed. A few possible ways is put forward which can be used in planning innovation, and have vivid leading function to the frondose city planning method.     

Relations between Urban Design and City Planning in the Work of Plan-making

In this paper, three fundamental principles of city planning under the present system are brought forward: the integration of urban design and city planning, the double attributes and position of the urban design and the correspondence between the urban design and the city planning in levels. Therefore, according to the different circumstances, three functioning ways for the urban design in the practice of plan making are put forward: to put the urban design into the system of city planning, to work out the urban design as a research work and then make use of its achievement in the work of plan making, and to regard the urban design as a specialized work of city planning.     

Simple Analysis of the Thermal Environment in Chongqing

There are a series of city environmental problems especially in the mountain city along with the city fast development. In recent decade, many scholars have studied the urban heat island, the urban temperature, the urban wind field, the precipitation and the urban visibility etc. But the urban thermal environment has not been settled radically. All the measures have not been used in the practice. And the researches in thermal environment of the mountain cities are very few. So the authors consider Chongqing as the researching object. Chongqing is one of the typical mountain cities in the semi-tropical. Sequentially we find out the characteristic of the thermal environment in the mountain city. Further the authors seek for the measures to plan and build ecological city. They conclude that CFD can be used in the simulation of urban environment, and use the result of simulation in urban planning is possible. The thermal environment in the center of Chongqing needs to be improved.
