The Study For Theory And Construction Of Urban Green Network

The level of urban green space system planning directly affects the urban living environment, and affects the city's overall style and ecologically sustainable development as well. Therefore, the study of it's mode is concerned in recent years. At the same time, Relevant researches, theories as well as study are complex and appear after another.In recent years, urban green network theories and practice are quietly rising in the international community to promote a reasonable construction of urban green system. Through studying Green Network's basic theory, construction theory and appraisal theory, this paper further enriches and improves the systemic theory of urban green network. The purpose is to advocate its usage in urban green space system planning, offer reasonable basis for city garden management and scientific decision-making, and provide theory and method of direct guidance for the ongoing construction of urban green system at present stage of our country. The papers is as follows:1) To introduce history of development of urban green space system planning, and to summarize the present status and practice progress of the domestic and international green network theories so as to further infer the reasons for the origin o and related theories.2) To discuss the basic functions of urban green networks as well as the social and environmental benefits, and further propose elements, principles, methods for construction of green network so as to ultimately determine the green network thought of urban-rural integration by building the ecological planning.3) To study the evaluation system of the green network, this papers propose five one-level indicators for constructed evaluation system as followed, network structure, ecological function, ecological process, recreational function and quantitative index, and finally to build system of assessment.4) To describe ways and means of building urban green network according to local conditions in the actual projects in detail by studying construction of green space system planning of Chuzhou case. Meanwhile, to give evaluation and propose ideas of existing green space of Chuzhou by using the green network thought of integration of urban and rural ecological planning.
