Research on the Construction of Environmental Restoration Evaluation System of Urban Pocket Parks Based on AHP
In order to evaluate the restorative benefits of urban pocket park environment,this study selects relevant influencing factors through literature research at home and abroad,public questionnaires and expert consultation,and then uses AHP(analytic Hierarchy Process)to construct a recovery evaluation system of urban pocket parks with criterion layer including natural environment,public facilities,space composition and psychological perception and 21 indexes including water body,landscape quality and plant variety richness.At the same time,the weight of each index is calculated by the judgment matrix.The results show that(l)psychological perception is the most important factor in the criterion layer,and spatial accessibility is the most important factor affecting the environmental recovery evaluation of pocket parks;(2)Environmental health conditions,site belonging and rest facilities are important factors in the specific factor layer.This study provides a reference for landscape design and environmental restoration of urban pocket parks in the future.
