Study On Recreation Opportunity Spectrum Construction And Landscape Optimization Of Riverside Greenway In Hangzhou Main City

As a typical river network city,there are 470 river channels in the main urban area of Hangzhou.The riverside greenway,which relies on the river network,is closely integrated with urban space,which is the most widely used greenway type serving the population.It has distinct characteristics of space-time use.How to coordinate the environment of Greenway with the recreational behavior of people and reasonably match the opportunity of recreation will become an important direction for improving the quality of greenway.This paper selects 10 samples from the riverside Greenway in Hangzhou main city area,and takes the theory of Recreation Opportunity Spectrum as the guidance,establishes the evaluation system by factor analysis from three dimensions,namely,material environment,social environment and management environment,and 18 index factors.Through literature review,field investigation and Arc GIS analysis,the factors are checked,determine the recreational opportunity level of each greenway: comprehensive recreational riverside greenway includes the grand canal 1 and the grand canal 2.The daily leisure riverside greenway includes paster River greenway,Xitang river greenway,Shangtang River greenway,Yuhangtang River greenway,Tanghe District ring River greenway and Donghe greenway.The general traffic type riverside green road includes Zhonghe greenway and Guxin River greenway.Based on the analysis of the characteristics of recreational behavior of different types of greenways,the paper finds the internal relationship between environment and behavior: from general traffic greenway to comprehensive recreational riverside greenway,the arrival cost is gradually increased,and the recreation level is positively related to the proportion of tourists outside the city,average travel time,stay time and recreation activity richness,which is negatively related to the arrival frequency.According to the environment and behavior characteristics of greenway,the paper constructs the opportunity spectrum of riverside Greenway in Hangzhou main city area,which provides guidance for different source tourists to choose recreational projects in different periods.Finally,the paper puts forward the optimization design strategies of various greenway landscape,guided by the goal of providing rich and high-quality recreational opportunities.The comprehensive recreational riverside green road should be encrypted with traffic stations,the degree of road network connectivity,the spatial form of nodes being differentiated,cultural memory points increased,diversified participatory recreational activities should be carried out,the forms of rest facilities should be enriched,sports venues and facilities should be enriched,intelligent service facilities should be added to improve the level of environmental health maintenance;The daily leisure riverside greenway should improve the construction level of the green corridor,improve the utilization rate of large-scale gray space,control the richness of activities,add barrier free facilities,add daily basic supporting sports facilities,and add hydrophilic rest facilities;Generally,the traffic riverside green road should be widened properly,lighting should be extended,safety management level should be improved,and information integrity and richness of sign system should be improved.
