摘要:: 选取宝鸡市高新区排水管网齐全的区域为研究区，采用ArcGIS平台的水文分析模块及文献调查的方法，分析了区域发生城市内涝的原因。结果表明：河谷型空间形态、汛期强阵型降水以及自然地表向硬化地表的变化是宝鸡市城市内涝的主要影响因素。建设用地由2003年的11.52 km²增加至2013年的17.54 km²，是研究区内城市内涝频发的主要原因；分析研究区内道路的空间分布特征及河流的分布情况，设计方案，构建地表排水网络系统，将城市的雨水借地势、分圈闭、逐级分流排入支流，最终汇入渭河，合理引导区域内的水流，有效缓解城市内涝。

Abstract:: The area of drainage pipe network in high tech zone of Baoji City was selected as the research area. The hydrological analysis module of the ArcGIS platform and the literature survey method were adopted to analyze the causes of the urban waterlogging in the region. The results showed that the spatial form of the valley type, the strong formation precipitation in the flood season and the change of the surface properties of the ground cover matter were the main factors affecting the waterlogging in Baoji City. The construction land increased from 11.52 km² in 2003 to 17.54 km² in 2013, which was the main reason for the frequent waterlogging in the urban area. The analysis on spatial distribution characteristics of roads in the study area and the distribution of rivers were, the designing the drainage scheme, constructing the surface drainage network system to drain the urban rain water into the sub trap, the networks step by step, and the Weihe River can rationally adjust the water flow in the area and effectively alleviate urban waterlogging.
