Assessing The Suitability Of Urban Greenway Resources And Spatial Structure

City’s greenways in urbanization plays an important role in urban construction planning. To enhance the level of residents’living environment, ecological protection, traffic commute plays a pivotal role. Survey shows that although the greenway China starts relatively late, but in the last ten years has developed rapidly, some big cities in which the exemplary role of leading the city green way across the country. Green way of suitability to determine whether the green way of all kinds of resources are reasonable application, play its due effect, but the green way of spatial structure and reasonable layout to determine whether the scope of its services can provide convenient high quality service for the residents. Therefore, it can be said that the greenway suitability of spatial structure is the beacon light tower in the process of urban greenway development. Fuzhou City as a typical landscape garden city, landscape resources condition is superior, the rich historical and cultural resources, in numerous national green city representative, and its characteristics, this paper select Fuzhou as the research target, research in Fuzhou City green space structure suitability. Fuzhou greenway planning in Fujian Province, not only the green way of building construction interface, also ensures that the provincial green way connected to each other, so the greenway suitability for Fuzhou City green way itself plays an important role and position. In this paper, the existing 132 green way according to the city of Fuzhou characteristics and specific standards, selection of the 10 most representative green way, to evaluate its research, will, in Fujian Province and even the whole country a microcosm of city green way, to reveal and explore its characteristics and laws, looking for universal evaluation standard. Show according to the evaluation of Fuzhou City greenway planning and spatial layout, determine the green space structure suitability, points out its insufficiency, points out that according to the result of evaluation and put forward the corresponding opinions and Suggestions, provide data and theoretical basis for the research on follow-up.This study theory based on the deep interpretation of the greenway theory system and research on typical examples at home and abroad, integrated with the literature data collection, field investigation, to the actual situation of the research object and the paper discusses the feasibility of the method, concise out based on the greenway concept and suitability evaluation method suitable for this case. This study by combining analytic hierarchy process (ahp) and entropy value method of comprehensive evaluation way, obtain comprehensive weights of index layer, coupled with resource evaluation results, the calculation of coupling and coupling coordination degree, in order to evaluate the Fuzhou City green way of ecological, cultural, environmental and traffic resources. The results showed that:in Fuzhou City green way of resource assessment, among the four types of evaluation index, ecological and environmental indicators of green resources suitability has obvious effects, humanities class index for the greenway resources suitability is the lowest in the four, the influence of that the ecological environment shall be used as the first reference index of urban greenway planning line selection. Coupling results show that the Fuzhou City green way of coupling is very high but the coupling coordination degree is not high, although the coordination between system is good but not stable, need to be improved. This study using ArcGIS techniques, according to the related data of GIS buffer and all nodes of the greenway make OVD diagram for the analysis of Fuzhou City green space layout structure. Combined with the analysis of the two parts as a result, winning in Fuzhou characteristic green space suitability evaluation results. Results show that the spatial structure of Fuzhou City green way, from OVD figure to see Fuzhou City green way node station location and number of set up the basic reasonable, its service scope of intensity and density were positively correlated; Green way of 100 and 500 m buffer figure show that Fuzhou City green coverage is relatively reasonable, surrounding the basic contains most of the residential areas. Combination of both can be concluded that Fuzhou City green way did well on the suitability of spatial structure, scoring belongs to the good level, the basic to select reasonable, should be maintained.According to the Fuzhou City ten characteristics of green way of evaluation results, further research on Fuzhou characteristic green way of suitability and line selection, propose targeted the greenway system development strategy:to Fuzhou City green way the connotation of the comprehensive improvement and protection, broaden the urban greenway network development train of thought. To increase the number of node relay station, the rationalization of park green service scope, extended type. Create the policy support from the general, the public supervision, and the whole people to participate in an environment.
