每年进入汛期以后,全国各地因暴雨引起的城市内涝,造成人员伤亡和财产损失的报道络绎不绝。主要原因是,随着经济的快速发展我国城市化率快速提高,城市规模显著扩大,促成了城市岛效应并导致城市暴雨频发,再加上城市硬化面积的不断扩大,改变了城市原地表径流条件,使在同等暴雨洪水条件下,其灾害较比以往更加严重。因此,提出通过加强城市排水管网建设,改善城市路面透水条件,探索雨洪资源化的系统研究和推广等措施,可有效控制城市雨洪灾害。
每年進入汛期以後,全國各地因暴雨引起的城市內澇,造成人員傷亡和財產損失的報道絡繹不絕。主要原因是,隨著經濟的快速髮展我國城市化率快速提高,城市規模顯著擴大,促成瞭城市島效應併導緻城市暴雨頻髮,再加上城市硬化麵積的不斷擴大,改變瞭城市原地錶徑流條件,使在同等暴雨洪水條件下,其災害較比以往更加嚴重。因此,提齣通過加彊城市排水管網建設,改善城市路麵透水條件,探索雨洪資源化的繫統研究和推廣等措施,可有效控製城市雨洪災害。

After entering the flood season each year ,throughout the country due to heavy rains caused by urban waterlogging,causing casualties and property damage were reported flooded.The main reason is that with the rapid economic development of the rapid increase in urbanization ,city size significantly expanded ,contributed to the city island effect and lead to urban storm-prone ,coupled with continuous expansion of urban hardened area,changing the original urban runoff conditions for storm and Flood in the same conditions ,the disaster is more serious than over the past.Therefore,proposed by strengthening urban drainage network construction,im-prove urban road flooding conditions,to explore the resources of rainwater systems research and extension and other measures,can effectively control the city rainwater disasters.
