摘要
关中地区的用水量虽有波动,呈缓慢下降的趋势,农业用水的比重下降,工业及城乡生活用水比重增加。应用水均衡和耗水系数两种方法计算关中地区的耗水量为29×108m3。按地区西安耗水量最大,占关中的44.59%;按用水项目农业用水耗水量最大,占关中的70.23%。
Although the water consumptions had some fluctuation and shown the trend of slow downward in Guanzhong region, the specific gravity of agricultural water use has been drop down and the industrial and domestic water use in urban and rural areas has been increased. Using the balanced method of water and consume water coefficient method to calculate the amount of water consumed in this area, this amount was 2900 million m^3. Xi＇an water consumptions were most heavy and have occupied 44.59 % of the whole water consumption in Guanzhong region. The agricultural water consumption was the largest and has occupied 70. 23 % of the whole water consumptions in Guanzhong region.
