九龙江流域农业洪涝灾害损失时空变化特征OA

In the context of global warming,more frequent and intense precipitation in the future will bring great challenges to agricultural production.Based on this,we explored agricultural flood disaster losses and their temporal and spatial distributions in the Jiulong River basin,based on rainstorm and flood disaster data of 19 counties in the basin from 2014 to 2019.We also discussed adaptive agricultural man-agement practices in the Jiulong River basin that could reduce the damage to agriculture caused by flood disasters.We aimed to provide a scientific basis for developing resilient and sustainable agriculture in the Jiulong River basin,offer macro-level reference for agricultural insurance in different areas of the basin,and acquire data for establishing vulnerability curves of agricultural losses due to flood disasters.Results show that:(1)Losses in agricultural production caused by flood disasters were primarily tea,vegetables,fruits,and edible fungi.(2)The largest flood related losses in agricultural production occurred in the months of September,July,May,and June,and the losses correlated with the annual rainfall(R=0.714,P=0.009).(3)The counties and county-level cities suffering the largest agricultural losses in the Jiulong River basin were Anxi County,Tong'an District,Changtai County,Hua'an County,Liancheng County,and Zhangping City.The overall spatial distribution of loss was characterized by larger losses in the middle and lower reaches of the basin and smaller losses in the upper reaches.Finally,we put forward agricultur-al flood disaster management measures from the perspective of disaster prevention and mitigation.
