[Objective] We conduct research on the evolution of drought in China and its impact on agriculture in recent years. [Method] We analyze 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. [Results] 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.
