淮河流域农业干旱对粮食产量的影响分析
摘要
Abstract
Drought is the main factor for restricting the grain yield in China and has serious impact on agricultural products and food security. The Huaihe River Basin seriously suffered by drought was taken as a study case. The analysis of the statistical data of historical drought disasters indicated that the drought disaster became more and more serious over time and there was large difference between the administrative areas. The influences of agricultural drought disasters on the grain yield in the river basin from 1999 to 2008 were verified by the empirical tests on the relevant data. The results show that the agricultural drought disasters have obvious influences on the grain yield. Some policy suggestions are proposed. It can provide reference for the food security and the agricultural disaster prevention system of Huaihe River Basin.关键词
