Abstract

The invention relates to a method for sudden accident risk zoning of a river basin based on changes of water resources, which comprises the following steps: 1) carrying out drought risk zoning within a selected zone scope according to drought risk indexes; 2) carrying out flood disaster zoning within the selected zone scope according to flood risk indexes; 3) carrying out sudden accident risk zoning within the selected zone scope according to sudden accident risk indexes; and 4) superimposing zoning results in a GIS (geographic information system) to realize sudden risk zoning under different precipitation conditions. The conditions of the water resources are taken to account for sudden accident risk zoning, the sudden accident risk zoning results of zones are more reasonable and reliable, and the scientific level of regional environmental management can be improved. Moreover, the sudden accident risk zoning results of the zones can be displayed promptly through the GIS technology, and the accuracy of integrated environmental management can be improved. Meanwhile, the method has high operability and a wide scope of application and is suitable for zones of different sizes.

Description

technical field

[0001] This patent relates to the fields of accident environmental risk assessment, natural disaster risk assessment, and GIS technology application, especially a "GIS platform-based water resource change risk division method for river basin emergency accidents." Background technique

[0002] Most of the regional risk problems are caused by the interaction of multiple factors, and its action time and consequences are difficult to predict. Therefore, it is very important to comprehensively evaluate and partition regional risks. With the advancement of industrialization and urbanization, sudden environmental pollution accidents occur frequently in our country, with increasing impact and losses, which have become an important factor that hinders regional economic development and threatens environmental safety and human health. At the same time, disasters caused by natural factors (such as floods and droughts) in the region will also cause damage to human health ...
