摘　　要：城市内涝现象在我国许多城市经常发生,带来的损失也相当严重。本文以福建省三明市沙县为研究区域,设计重现期20年的降雨,对研究区域降雨径流过程进行模拟,通过PySWMM与Cesium进行集成和交互,在Cesium上进行涝点的提取。实验表明,通过Cesium能够很好地调用模拟降雨过程的数据,并能够在Cesium上进行可视化展示,以此提取出城市的潜在内涝点。Urban waterlogging is a common phenomenon in many cities in China,causing considerable damage.This paper focuses on Shaxian County in Sanming City,Fujian Province,as the study area.A rainfall event with a 20-year return period is designed to simulate the rainfall-runoff process in the study area.Through the integration and interaction of PySWMM with Cesium,inundation points are extracted on Cesium.The experiment demonstrates that Cesium effectively accesses data from the simulated rainfall process and enables visualization on its platform,allowing for the extraction of potential urban inundation points.
