摘要
采用受灾率、成灾率、降水变率、脆弱度、灾害损失率等指标,评估湖南省洪涝灾害农业风险度,并分析其时空分布特征,得出:该省洪涝灾害发生地域由北向南转移,风险概率呈增加之势。根据洪涝灾害农业风险度时空分布特征,提出相应的防灾减灾对策,以期能为防御和减轻洪涝灾害提供参考。
By using the ratio of disaster-affected area,the ratio of disaster-suffering area,precipitation variability,fragile degrees,calamity loss rate,the temporal and spatial distributional characteristics of the agricultural risk of flood in Hunan province were evaluated.The results showed that the flood region had transferred from south to north in Hunan,and risk probability had a serious tendency.Based on temporal and spatial distribution characteristics of the agricultural risk degree of flood,some measures of disaster prevention and mitigation were proposed to provide a reference to avoiding or abating the influence of flood.
