摘　　要：近10年来,云南省粮食产量在波动中增长,从2000年的1 467.8万t增长到2010年的1 531.0万t,灌溉是该区粮食高产稳产的重要保证。农业是用水大户,工农业用水比约为1∶3,水资源供需的主要矛盾在农业。目前云南部分地区用水紧张,随着工业和城镇的发展,农业用水分额将继续减少;同时,受频繁的旱涝灾害、日益严重的水污染、水资源的空间分布与经济社会发展不匹配和水资源开发难度大,利用效率低,浪费严重的影响,农业供水保证率将进一步降低。要继续保证或发展该区的粮食生产规模,该区的农业用水情势有恶化之势,急需研究并制定出解决该区粮食生产和水资源供给不足矛盾的办法。Food production in Yunnan Province in recent 10 years is in the wave of growth,from 14.678 million tons in 2000 to 15.31 million tons in 2010.Irrigation is an important guarantee to ensure high and stable yield of grain in the area.Agriculture is water conservation,industrial and agricultural water use ratio is about 1∶3,the main contradiction of supply and demand of water resources is agriculture.At present,parts of Yunnan water stress along with the development of industry and urban,agricultural water amount will continue to reduce;At the same time,the frequent flood and drought,the increasingly serious water pollution,water resources does not match with the economic and social development and water resource development is difficult,low efficiency,waste of serious,the influence of agricultural water supply reliability will be further reduced.In order to continuously guarantee or develop scale of regional food production,it is urgent to research and formulate method for solving contradiction between grain production and water resource insufficient supply.
