摘　　要：对甘肃省民勤县 1949～ 2 0 0 0年农业统计资料分析结果表明 ,该县绿洲作物种植结构和产量发生很大变化 ,粮食播种面积占总播种面积比重总体呈下降趋势 ,其中小麦种植面积 1982～ 1998年下降 15% ,玉米、棉花及其他经济作物种植面积比例呈增长趋势 ,黑瓜籽增幅达 10 %。The agricultural statistical information of Minqin Cou nt y during 1949～2000 was analyzed. The results show that there are great changes on the planting structure and yield during this fifty-two years in the oasis of Minqin County. The total tendency of the planting area of cereal crops in propo rtion to the total planting area is minishing. The wheat planting area has been reduced by 15% from1982 to 1998,while those of maize,cotton and other economic c rops have been increased,especially that of the seed melon has been increased by 10%. Finally,the relationship between the crop water requirement and the water resource-carrying capacity and their affections to adjust agricultural producti on are analyzed.
