基于GIS的复杂河网区域洪水灾害风险评价
Flood Risk Analysis in Complex River-networks Area Based on GIS
摘要
Abstract
There are some flood plants in the middle and lower reaches of the Yangtze River, which become complex river-network areas because of the climate, terrain, history and artificial effect. These areas are frequently threatened by floods, and can not cope with flood disasters, so it is urgent and hard for us to make flood disaster risk zonation in these areas. As general factors, such as rainfall and terrain, can not describe the risk properly in these complex river-networks areas, we have used river-networks' density, soil structure and so on to make sub-flood risk evaluation in the case of Chongliu Area in Changde, Hunan. The more the research progress, the more achievements we can get, We have used this way to control and plan flood resources.关键词
