摘　　要：在干旱半干旱地区，可进行调整农业结构，使农作物需水量与降水量适时同步，以充分利用雨水资源。通过对邢台市降雨特性分析，该区降水比较集中，汛期降水量占全年降水量的80％；通过对该区常规种植作物需水量分析，冬小麦一玉米一年两熟农业结构，少雨期正是小麦需水期，在平水年单位面积缺水量为368．4mm。结合该区降水特性调整农业种植结构，在水资源相对丰富的地区，保证粮食作物的种植面积；在水资源匮乏的区域，种植棉花作物．使得降水季节与作物需水期相适应，从而达到充分利用雨水资源的目的。In the arid and semi-arid area,we can adjust the agricultural structure and make the crop water requirement and precipitation timing synchronization in order to make full use of water resources. Through the analysis of rainfall characteristics in Xingtai City, we find that the pre cipitation of this area is relatively concentrated and precipitation in flood period accounted for 80 ; of the annual precipitation;through the analy- sis of the water requirement of conventional crops, in the winter wheat-corn double cropping agricultural structure, we find that the period of less rainfall is also the period during which wheat is badly need of rainfall water,and the water deficit in per unit area is 368. 4 mm in median water years. Combined with the precipitation characteristics of the area, we should adjust agricultural planting structure. In order to make full use of rainwater resources, we should ensure the planting area of grain crop in the area where the water resources is relatively rich, and planting cotton crops in the area where the water resources is scarce to make the raining season fits the crop water requirement period.
