| 摘 要： | 以重庆秀山县为研究对象。对建国后50年中各年代人为因素对农业旱灾的作用进行了比较，探讨了其成因及变化趋势。研究表明，在20世纪50年代和60年代，秀山县由于生态破坏、水利设施不足和不合理的政策导向等，人为因素起着加剧旱灾灾情的作用，而在70年代至90年代。由于农业基础设施投入的加大、抗旱政策的制定等，人为因素开始起着越来越强的缓解灾情的作用。 |

| Abstract: | Taking Xiushan County, Chongqing, as the object, the paper compares human factors action on agricul- tural drought in every decades since 1950's, and studies the causes and change tendency of the drought. The result shows that because of the destruction of ecological equilibrium, the lack of water conservancy facilities and unrea- sonable policy, human factor aggravated the losses of agricultural drought in 1950's and 1960's. But because of the enlarged input in agricultural infrastructure and the policy on fighting drought, human factor lightens the losses of agricultural drought in 1970's, 1980's and 1990's. |
