摘要
分析20世纪50年代以来西安市用水结构的变化及造成这种变化的主要驱动力。结果表明:20世纪50年代以来,西安市总用水量不断增加,农业是用水大户,但自90年代初期开始,农业用水量开始下降,工业用水量和生活用水量持续上升,到21世纪初期,工业用水量依然保持较高的增长速率,生活用水量缓慢增长。耕地面积的减少和节水灌溉面积的增加是农业用水量减少的主要原因;人口增长、居民生活水平的提高是生活用水量增加的主要原因;工业产值的迅速增长是工业用水量迅速递增的原因。最后,提出充分利用中水资源、调整产业结构的节水措施。
The change of the water consumption structure of Xi＇ an City since the 1950s and its major driving forces were analyzed. The results show that the total water consumption in Xi＇ an City has continuously increased since the 1950s. Agricultural water use has decreased, and industrial and domestic water use has continuously increased since the early 1990s. In the early 21st century, the industrial water use maintained a high increase rate, while the domestic water use increased slowly. The main cause of the decrease in agricultural water use was a reduction of cultivated land and an increase in the area of water-saving irrigation. The increase of population and improvement of people＇s lives are the main causes of the increase of domestic water use. The rapid increase in industrial output has increased the industrial water use. Some water-saving measures are proposed, including reclaimed water utilization and industrial structure adjustment.
