[目的]对我国近年旱情演变及其对农业造成的影响进行研究。[方法]汇总分析了1978～2008年我国发生重大旱灾的土地受灾面积、成灾面积、成灾率,以及全国农作物播种面积及其受旱灾影响情况。[结果]近年来,我国大部分省市,尤其是南方地区,旱情并没有减轻,反而有逐渐加重的趋势;自1978年以来,我国由于旱灾导致的成灾面积在迅速增加,且干旱导致的农作物绝收面积总体也呈现上升趋势,同时,由于人口增加和和经济发展导致粮食播种面积减少,导致了粮食的总产量增长缓慢。[结论]构建和谐流域,实现人水和谐相处,就要在科学认识和正确运用自然规律的同时,规范人类自身行为,进一步做好相关的生态环境保护工作。

[Objective] To research the evolution of drought in China and its impact on agriculture in recent years. [Method] We analyzed land area covered, area affected, and disaster rate arising from severe drought occurring in China in the period 1978-2008, in conjunction with the planting area of crops in China and forcing of drought on the planting area of crops. [Result] In recent years, a large portion of provinces and cities in China, especially the southern areas, the drought has not yet been eased, but tends to deteriorate; since 1978, the area affected in China occasioned by drought has been rapidly mounting, and total crop failure area caused by drought, on the whole, also assumes trend of rise. In the mean time, population explosion and economic development are responsible for dwindling of planting area of grain, and tardy rise in total grain yield. [Conclusion] Constructing harmonious valley and achieving concordant coexistence between human and water, is to regulate human behaviors and further strengthen related ecological protection work, on the basis of scientifically understanding and correctly harnessing natural law.
