摘　　要：青浦圩区除涝能力评估是管理单位检验自身管理现状的基础。本文以青浦圩区面积和圩内水面率为研究对象进行除涝等级划分,运用GIS叠加分析方法评估圩区除涝现状,与《青浦区水利规划(2022—2035)》中圩区除涝评估经验值对比,分析得出圩区除涝能力“优良中差”等级,并制作评估能力分布图。本研究成果可为圩区长效管理和系统建设发展提供参考。The assessment of drainage capacity in the Qingpu Marsh Area is the foundation for the management authorities to examine their own management status.This study focuses on the area and water surface ratio within the Qingpu Marsh Area to classify drainage levels.It utilizes GIS overlay analysis methods to evaluate the current drainage situation in the marsh area.A comparison is made with the empirical values for drainage assessment from the Water Resources Planning for Qingpu District(2022—2035).The analysis results in categorizing the drainage capacity in the marsh area as“excellent,good,fair,or poor”,and a capability distribution map is generated.This research can serve as a reference for long-term management and the development of systematic construction in the marsh area.
