Urban Green Space System Space Reasonable Evaluation

Urban green space is an important place for urban life and natural contact, so it place a vital role in maintaining urban environment, protecting biological diversity in city, promoting ecosystem stability and improving the quality of life of city residents. As more and more attention were placed in construction of urban green space, in fact, urban green space has already become one of basic infrastructure of urban sustainable development of critical as well as important component of the eco-city construction. Therefore, the establishment of a scientific and rational evaluation system of the space of rational of urban green space system is very important.With the accelerating process of urbanization in China, there exists unreasonable phenomenon in resources utilization, causing serious environmental problems and or even productive crisis, which makes people have to re-recognize the relationship between man and nature.Based on a large number of domestic and international materials, this paper studied on an evaluation system for reasonableness of urban green space system and took Zhuzhou City as an example. The conclusions were as followed:(1) Establishing the reasonable program of urban green space system, the preparation method was optimized; through rationally analyzing theoretical concepts of urban green space system and studying on domestic and international urban green space system index evaluation system, a rational system to establish the theory and methods of urban green space system space for was constructed;(2) Evaluating the urban green space system by using reasonable evaluation index system and associated evaluation methods, constituting an organic whole of the evaluation results; the evaluation of urban green space system has multiple features and can be divided into rational indicators, emotional indicators, quantitative indicators and qualitative indicators, which are standards and contents for evaluation of urban green space;(3) Based on the whole evaluation system of urban green space, the elements and structure, a comprehensive evaluation system for urban green space was built up and16indicators were picked up;(4) Taking Zhuzhou City as an example, a comprehensive evaluation system of rationality of urban green space was established. Zhuzhou urban green space construction and green space landscape were studied in Zhuzhou city, and evaluation results of evaluation system of rationality of urban green space were graded into three classes.The evaluation system of rationality of urban green space needs deeper study by experts and scholars in this area, and strong government cooperation and the city digitalizing program needs to be developed more. Through the establishment of spatial database of high precision and the common effort from academic communities and scholars, the study on this evaluation system of rationality of urban green space can be developed deeper and the city’s green construction can by promoted as well.
