安徽省干旱危险性评价及等级划分
Evaluation and Classification of Drought Hazard in Anhui Province
摘要
Abstract
Regional drought hazard assessment is the foundation for implementing drought hazard management and can pro-vide scientific and effective decision-making basis for drought prevention and disaster reduction work.A quantitative evalua-tion method of drought hazard in Anhui province based on risk index was established by selecting water resources and pre-cipitation data of 104 county-level administrative regions in Anhui Province.The method was applied to evaluate the drought hazard of various counties and districts in Anhui Province,and a distribution map of drought hazard levels in Anhui Province was obtained.The results are as follow.In the county-level drought hazard zoning map drawn based on the calcu-lation results of water resources and precipitation data,except for some counties with different risk levels,the distribution of drought hazard levels in Anhui Province gradually decreases from north to south.The overall trend of drought hazard in An-hui Province is closely related to its natural geographical distribution and is influenced by social development.The research results can provide support for drought hazard zoning in Anhui Province.关键词
