大庆市属于严重缺水地区．腹地无天然水系，地表水资源贫乏，农业用水主要利用地下水。虽然地下水资源比较丰富，但区域之间分布不均衡，存在部分贫水区和超量开采区。而且利用地下水的唯一途径是凿井取水，投入高，效益低。因此在水资源贫乏地区，必须走节水灌溉的道路。面对 Daqing City is a serious water shortage area. There are no natural waterways in the hinterland, the surface water resources are scarce, and the agricultural water mainly uses groundwater. Although abundant groundwater resources, the distribution is not balanced between regions, with some areas of poor water and over-exploitation. And the only way to exploit groundwater is to drill the shaft to take in water, to invest high and to have low efficiency. Therefore, in water-scarce areas, we must take the road of water-saving irrigation. face
