Compilation and Reflection on Flood Risk and Prevention Zoning in the Beijiang River Basin
摘要
Abstract
Flood risk zoning and prevention zoning are important contents of the national comprehensive risk survey of natural disasters,and are a new foundation for scientific decision-making,planning,and management of flood control and disaster reduction.Taking the Beijiang River Basin as the research area,a quantitative assessment of flood risk in the study area was completed through the construction of zoning analysis models,analysis and calculation of risk factors,and classification of risk levels.The zoning results show that the areas with extremely-high-,high-,and medium-risk of flood disasters in the Beijiang River Basin are 1055.60km2,1144.55km2,and 1174.40km2,respectively.The areas of the first and second level key prevention and control zones in the main river flood control areas are 87.80km2 and 141.90km2,respectively.Based on the flood risk zoning and prevention zoning of the Beijiang River Basin,countermeasures for regional flood prevention work have been proposed,providing technical support for flood disaster prevention work.关键词
