摘　　要：为了最大力度地发挥滇中受水区农业节水潜力,实现农业可持续发展,拟对滇中受水区农业节水潜力进行估算分析。以2017年为现状基准年,2030年为规划水平年,基于滇中地区气象站、实地调研等数据资料,拟定5个节水发展情景,利用水利部推荐的农业节水潜力计算方法计算各情景下的农业节水潜力,并进行区域粮食安全与节水投资效益分析。结果表明:滇中受水区在规划水平年2030年灌溉水利用系数平均水平达到0.69,节水灌溉率达80%,高效节水灌溉率达30%;在现状年基础上,根据各受水小区实际种植结构,将水稻种植面积在-10%~3%的范围内调整时,在保障区域粮食安全的基础上,可实现18782万m^(3)的农业节水目标。To maximize the agricultural water saving potential and achieve a sustainable growth,we estimated and analyzed the water saving potential in the water receiving area of central Yunnan Province.Based on meteorological and field survey data,we designed five scenarios of water saving and calculated the water saving potentials in each scenario using the calculation method recommended by the Ministry of Water Resources with 2017 as the current benchmark year and 2030 as the planning level year.We also analyzed the regional food security and the benefits of water saving investment.Results demonstrate that in the planning level year 2030,the average irrigation water use coefficient in the study area will reach 0.69,water saving irrigation rate will amount to 80%,and highly-efficient water saving irrigation rate 30%.By adjusting the rice planting area within the range of-10%-3%according to the actual planting structure based on the current benchmark year,we can save 187.82 million m^(3) of agricultural water on the prerequisite of ensuring regional good security.
