Construction Of Recreational Greenway Network In Main Urban Area Of Fuzhou City

Greenway has improved the city’s ecological environment,improve the quality of life of city residents,has been subject to relevant researchers attention.In the rapid accumulation of population in the city,people want to be able to have the leisure and recreation in the study of the place for physical and mental relaxation,for the demand of city green leisure space more and more reasonable.The line planning green road to series of recreation resources in the limited land resources,promote the protection and restoration of city natural resources and human resources,enhance the service function of city recreation resources,city recreation to avoid waste of resources,increase the city green area,the green city residents to meet.Therefore,it is very important to construct the urban recreational greenway network for the construction of livable cities.In this paper,the main urban area of Fuzhou as a research object,using the suitability analysis and network structure analysis method to build the main city of Fuzhou recreational green road network.Using the suitability analysis method to quantify the research area,obtain the nodes of the recreational greenway network.Using suitable nodes building four recreational greenway network solutions according to the construction method of Greenway Network.The network structure analysis method is used to analyze the structure index of the four initial network and obtain the best potential network scheme.Superimpose the urban natural human resources and the existing greenway,access to the main city of Fuzhou recreational greenway network.The main conclusions of this study are as follows:(1)Through review the literature of the evaluation factor,using theoretical analysis and frequency statistics method to summarized the evaluation factors that influence the selection of greenway network,combined with the construction goal and the functional requirements of Fuzhou,finally,selecting seven evaluation factors which is the types of land use,habitat attraction,population density,traffic analysis,flood buffer and resource buffer,reachability analysis of residents walking,analysis of historical and cultural points cycling accessibility(2)Based on the evaluation factors of suitability analysis by using GIS technology,from the analysis results,Gulou and Taijiang district is high land utilization,Cangshan and Jinan district is the second;The main area of the urban habitat patch attractive area accounted for 40.87%of the total area.The densely populated area mainly concentrated in the Taijiang and Gulou district.The accessibility of urban residents accounted for 85.44%of the study area shows a good overall situation,the poor accessibility of the place concentrated in the Cangshan district of northern Huaian residential green,Cave Hill blocks,ecological green space of Gaogai mountain and Chengmen mountain’s center land,Guanchanzhou green block,Huizhan center area,and the Qingliang mountain’s southern area,Zhaiding mountain.Culture history high accessibility is in Gulou and Cangshan district along the Minjiang river side,low accessibility is in Cangshan district along the wulong river side.Using the weighted stacking formula and the GIS grid calculator,the recreational greenway network of Fuzhou city is suitable for the construction area and the network connection point.It is found that the area of the Gulou District and Cangshan District is suitable for construction,and the area suitable for construction in Taijiang District and Jin’an District is small.Among them,a total of 90 network access points,of which senior grade is 56 nodes,second is 34 nodes.Combined with the construction of Fuzhou recreational resources,from which to determine the completion of nodes and potential nodes,a potential senior grade node is 15,two potential second nodes is 16.(3)Using network structure analysis,access to the best potential network solutions.The results show that the built-in node network line is basically consistent with the existing recreational green road in the main urban area of Fuzhou.For the connection of potential nodes,the existing linear resources of Fuzhou are used to determine the trend of the potential node network.Superposition of potential node network lines,built node network lines and Fuzhou natural human resources to build Fuzhou main city recreational greenway network.This paper mainly analyzes the suitability of land resources in the main city of Fuzhou.On the basis of this result to analysis network structure for the optimization of tourism resource allocation,so that improve the city recreational greenway network performance,provide a reference for city recreational greenway network of scientific planning.
