A Research On Evaluation Index Of Urban Green Space System Planning

Along with the global industrialization and urbanization of the continuous in-depth development caused a series of environmental problems, ecological crisis become today facing mankind biggest crisis and the severe challenges, repair the damaged the ecological balance and rebuilding the appropriate living environment become an important topic of concern around the world. Urban green space system planning is urban ecological infrastructure important special planning, is the important guarantee to realize the benign circulation of urban ecological environment, improving the urban ecological environment and meeting the requirements of residents’ leisure entertainment, the organization of urban landscape and beautify the environment and disaster prevention to avoid disaster plays an important role in. Since the 90 time of last century, the urban green space system has been paid more attention by the researchers of national, government and landscape architecture.. On the one hand, the state and governments at all levels through the promulgation of green planning and greening construction regulations, bills, guidelines and so on to gradually standardize the preparation and implementation of the plan for the preparation and implementation of the various links. On the other hand, professional researchers added to the planning of the study, the continuous expansion of the research theory, method and content, in many of the city’s green space system planning has been reflected. At present, most of the cities in China have completed the preparation of the plan.. However, although the traditional planning ideas and methods of the new content, but the depth and breadth of planning programming is still insufficient. At the same time, because of the standardization of the content, the fixed content of the plan also makes the plan for the urban green space construction lack of guidance. So establish a set and evaluation system of the urban green space system planning phase matching, is conducive to the preparation of urban green space system planning, helps to promote the construction of the urban green space in China; the plan of scientific evaluation, making it more effective and guide urban green construction and for the government to provide a testing scheme, in order to better select appropriate planning scheme.In this paper, the main research method for literature and review of the system of the previous and current scholars on urban green space system planning evaluation, evaluation index and index system related research results. Summarized and summarized the urban green space system planning evaluation, evaluation index research status and the main problems, for building a new index system to do a certain basic research. Subsequently, on the evaluation of urban green space system planning on the basis of the theory of decomposition and analysis of factors related system comprehensive analysis method, application related disciplines theory and method such as ecology, landscape ecology, landscape science, economics, urban planning, social science, the discipline of disaster prevention hedge, matched with the urban green space system planning evaluation index system construction. With a combination of quantitative and qualitative analysis methods, including the expert scoring method, frequency analysis method, GIS technology, field investigation, AHP evaluation method, establishment of urban green space system planning in the three spatial levels of analysis methods and evaluation system. Through the research related to green space system planning evaluation, urban aerial map for basic research, information and rocker technical analysis and GIS platform support, combined with actual case, analysis of the construction of evaluation index system of the rationality and deficiency and its application in actual green space system planning case, to the rationality evaluation scheme. The main body of the full text of four parts. The first part introduces the evaluation of urban green space planning in the process of development in western countries, and puts forward the research purpose, significance, research methods and technical route. The second part is the basic research. Firstly, the main concepts and the main functions of urban green space system planning are discussed.. Then combing, western countries urban green space and planning evaluation related concepts, theory, method and the main evaluation index, the similarities and differences between the analysis and comparison of the domestic research status and abroad research, summed up the study is available for reference the theory, methods and indicators; the third part for the evaluation index system of green space system planning construction and case study. First of all, the main problem of combing the connotation of city green space index system and face, and to build a "green, ecological evaluation and landscape, economy and disaster prevention" as the main content of the evaluation system; to quantitative indicators, ecological landscape, relevant indicators of economic hedging and disaster prevention and related laws and regulations, respectively established the green space system planning evaluation index system of the three space city area, planning area and built-up area level, and each single index is described; then, through the analytic hierarchy process to quantify each index, the weight of each index value, and sort; finally, taking Yancheng City urban green space system planning (2011-2030) as a case, using the built evaluation index system of evaluation area green space system planning; the fourth part, the conclusion of the paper, the main research results of this paper, the shortcomings and defects, and to study the outlook for the future, provide a reference for future research.
