Space Evaluation and Optimization of Urban Park Green From Perspective of Supply and Demand
Taking Yuexiu District,Guangzhou,Guangdong as an example,the index system of supply and demand measurement is established by analytic hierarchy process method and expert consultation method,two-step mobile search method,service area analysis method and OD cost matrix method are used to evaluate the park green supply.Using the location entropy method,the resident demand is evaluated for total popula-tion density and population densities of different groups;using the coordination model,the evaluation of sup-ply-demand coordination degree and supply-demand relationship of park green space is obtained.The results show that the overall supply level of park green space in Yuexiu District is high,but the supply of different streets varies significantly.The overall demand level is high and distributed in a horizontal strip shape.The spatial difference of unbalanced distribution of supply and demand is obvious.The coordination degree of sup-ply and demand is benign,but some areas with supply-demand imbalance and insufficient supply would be opti-mized necessarily.
