Research On Sustainability Evaluation Of Urban Rainwater System In Zhangjiang New District Of Zhangzhou City

In recent years,the development of many cities in China suffered the threat of urban waterlogging problems.Urban waterlogging is regarded as a new urban problem.Urban development has had a negative impact.Urban stormwater system bear the city rainwater collection and discharge.It is important infrastructure of city security.So,it is very necessary to build a sustainability evaluation system for urban stormwater system.We use this system to carry out sustainability assessment and evaluation of the urban stormwater system,through the results of the evaluation study to determine whether sustainable urban stormwater system,and even the degree of strength can be evaluated on its ability to sustainability.Through the sustainability evaluation of urban stormwater system,to provide decision basis for city managers,also can provide guidance for the development of the city and the management.Based on the study of urban stormwater system to analyze the relevant literature at home and abroad,combined with the theory of sustainability evaluation,to build a new urban stormwater system sustainability evaluation system,the fuzzy comprehensive evaluation method was used to construct sustainable evaluation model of urban stormwater system.Take urban stormwater system in the Zhangjiang New Section of Ganzhou as a research example,this study verified the feasibility and effectiveness of index system and the evaluation model of urban stormwater system;Finally,this study come to the conclusion,point out some problems and put forward the expectation.This study built sustainable index system and evaluation model,enrich the evaluation system of urban stormwater system,provided a reference to the future construction of urban stormwater system,promoted sustainable urban development.These have certain theoretical meaning and practical value.
