Research on Sponge City Suitability Based on Functional Area Difference——A Case Study of Yangzhou City
In the construction of sponge city,it is found that full consideration of the difference of urban functional areas is a difficult point and key issue of construction,so it is very necessary to select suitable LID measures.This paper takes Yangzhou sponge city construction as an example,it selects four different urban functional areas to analyze their internal structural features based on the surface cover conditions. It studies the differences in surface features,and discusses the suitable LID measures and the best combinations.In addition,we analyzes the effect and easement of construction,and maintenance requirements of LID measures in different functional areas.Finally, the advantages, disadvantages,and the urgency of LID measures construction are presented.The results show that the process of Yangzhou sponge city promotion should be carried out in the order of the following sequence:residential area-education area-commercial district-industrial area. The difficulty of the construction ranges from residential area to commercial area,followed by industrial area and education area.The highest construction efficiency is education area, residential area-industrial area-commercial district followed orderly.the construction efficiency follows the order of the academic area,residential area,industrial area,and commercial district.
