Research On The Service Level Of Green Spaces Based On GIS&RS Of Hangzhou

Green space is the only ecosystem area that is close to nature in the city. It has an irreplaceable function in improving the urban ecological system and meeting the residents’recreation, physical and mental health, etc. The service level of green space can integrate a variety of factors to evaluate the service capability of it, which will reveal the utilization degree and reflect the spatial distribution of the value of it. The service level of green space is a significant reference factor to measure the living quality of a city and the harmonious relationship between human and nature.In this paper, I analyze the service level of Hangzhou city’s green space from two aspects:the accessibility and the service efficiency, to objectively understand the present situation of Hangzhou city’s green space construction and distribution. Combining the analysis result and the related planning of Hangzhou city’s green space system, I put forward the optimization strategy from the angle of planning. Thesis is mainly divided into the following five parts:Part one introduces the backgrounds, significance, purposes, contents, innovations and defines the research objects. By reviewing relevant research literature in our country and abroad to understand the research dynamic, master related theories and methods, and determine the framework and technical route of this study.Part two explains the conception, classification and function of green space first. Then, summarize the accessibility and service efficiency, the two aspects of the service level of green space. Then the evaluation parameters and analysis steps of accessibility and the evaluation indexes of service efficiency were expounded in detail.Part three introduces the basic situation of Hangzhou city. By unscrambling the history of the construction of Hangzhou city’s green space and related planning to understand the development direction and construction requirement of it.The fourth and fifth part is the core of this thesis. Part four carried out case studies on the service level of Hangzhou city’s green space. Set up spatial database according to the data first, and then determine the service radius of green space. Finally, using buffer analysis, network analysis and cost analysis method to analyze green space accessibility, and coupled with residential land and population distribution data to analyze the service efficiency of green space. At last analyze the service level of Hangzhou city’s green space according to the results.Part five, through comprehensive comparison, analyzing the result of the study on service level of green space, the present situation of its distribution and related planning, has a summary about the construction situation of Hangzhou city’s green space, and put forward the corresponding optimization strategy from two aspects: construction and administration according to the summary.
