摘要
运用水文学、气候学、地貌学、计算机和GIS技术,采集了杭州地区824站的年降水实测资料,推求出了23个雨量站的暴雨强度公式,对整个杭州市的设计暴雨强度空间分布进行了深入研究。利用趋势面配合距离加权方法绘制了短历时暴雨强度等值线,并建立了设计暴雨强度信息查询系统,为杭州市的雨水排水工程规划建设和管理服务。
By utilizing hydrology, climatology, geomorphology, computer and GIS technology, measured data on the annual rainfall of 824 stations in the Hangzhou region were collected, and the formula of storm intensity in 23 rainfall stations was ascertained. Meanwhile, the space distribution of storm intensity was researched. With the combination of trend surface and weighing method, the isolines of short duration storm intensity were drawn and the information checking system for storm intensity was set up. Therefore, the service for the planning, construction and administration of Hangzhou rainwater drainage was provided.
