Study On The Spatial Distribution And Optimization Of Coastal Recreation Space In Fuzhou Based On GIS

With the rapid development of the national economy,the free time and income of urban residents have increased rapidly,and the demand for leisure recreation has expanded rapidly.The contradiction between the supply of urban recreation space and the demand for recreation has become increasingly prominent.As one of the four basic activities of the city,recreation is an indispensable part of urban development,and the recreation space has a significant impact on the leisure,daily interaction,fitness exercise,tourism shopping,sightseeing and other aspects of the citizens.Among them,the coastal recreation space,which is a unique feature of the coastal city,is the“best card”for the“Fuzhou at Sea”.With the development of the Fuzhou New Area,the population and economy of the coastal area of Fuzhou have increased significantly,and the demand for the quality and quantity of recreation space will further increase.However,it can be clearly seen from the current research on urban and rural planning system in China that there is a lack of planning control and the integration of recreation space.Therefore,it is urgent and necessary to study the spatial distribution characteristics and optimization of coastal recreation in Fuzhou.The research on the spatial distribution characteristics and optimization of Fuzhou coastal recreation is effective to comprehensively understand the type,overall scale,spatial structure and spatial layout of recreation space in Fuzhou coastal area,so as to optimize and integrate Fuzhou coastal recreation space for Fuzhou coastal area.The coordinated development of recreation space provides theoretical support.This paper studies the space of Fuzhou coastal recreation from three aspects.(1)Study on the spatial distribution characteristics of coastal recreation in Fuzhou.The spatial distribution characteristics of each type of recreation space are studied by the nearest neighbor index,Gini coefficient and nuclear density intensity.According to the research,he distribution of commercial recreation space is the most concentrated,followed by cultural recreation space,and the distribution of park recreation space and tourism recreation space is more random.Fuzhou coastal recreation space is generally distributed in an aggregated form.In terms of Gini coefficient,the overall quantity of Fuzhou coastal recreation space varies little among counties(cities)and is relatively average.In terms of various types of recreation space,the number of parks recreation space in each county(city)is the absolute average level.There is a small and relatively average gap between the number of tourist recreation space and cultural recreation space in each county(city).The number of commercial recreation space is more reasonable among regions.In terms of nuclear density intensity,tourism recreation space presents a strong distribution pattern in the south and a weak distribution pattern in the north,which is widely distributed.Park recreation space generally presents a pattern of strong in the north and weak in the south,with a wide distribution range.Cultural recreation space generally presents"three pillars",forming three regions with high nuclear density.The commercial recreation space is divided into strong in the south and weak in the north.Fuzhou’s coastal recreation space shows a strong distribution pattern in the south and a weak distribution pattern in the north.(2)Through the establishment of the Fuzhou coastal recreation space suitability evaluation system,the various recreation space in the coastal area of Fuzhou were evaluated as the basis for optimization.According to the research,it can be seen that four types of recreation space have formed three Grade I suitable areas in the county(city)center,of which the Grade I suitable areas for cultural and commercial recreation space are basically the same.However,there is a slight difference between the tourism and the park recreation space.Apart from the grade I suitable areas of the three centers,they are also widely distributed in coastal areas.In the suitability evaluation of various types of open space land,the proportion of grade I suitable areas for tourism and park recreation space is 0.08 with an area of 332.6km~2,while that for cultural and commercial recreation space is 0.06 with an area of 249.5km~2;The proportion of Grade II suitable areas for three types of recreation space,tourism,park and cultural recreation space,is 0.21,with an area of873.2km~2,slightly lower than 0.22 for commercial recreation space,with an area of 914.8km~2;The most largest proportion of Grade III is 0.34 with an area of 1413.7km~2 for cultural and commercial recreation space,followed by park recreation space with a proportion of 0.32 with an area of 1330.6km~2,and the least is tourism recreation space with a proportion of 0.28,with an area of 1164.2km~2.Grade IV suitable areas for all kinds of open space land occupy a relatively large proportion,of which grade IV suitable areas for tourism recreation space are the highest,with a proportion of 0.43 and an area of 1788.0km~2 The proportion of park and cultural recreation space is 0.39 and the area is 1621.6km~2.(3)Optimization study on spatial distribution of coastal recreation in Fuzhou.Based on the comprehensive study of the spatial distribution characteristics of Fuzhou coastal recreation and,the optimization of spatial distribution of various types of recreation is proposed.Finally,combined with the statusFuzhou costal area,the optimal distribution model of Fuzhou coastal recreation space is proposed in the“One Belt,Three Cores and Six Nodes”.
