中文摘要:
      在水足迹理论的基础上,对西北五省2000-2019年水足迹进行计算、分析和比较,并对其水资源利用状况进行了评价。结果表明:在研究时段内西北五省中陕西、甘肃、宁夏和新疆四省人均水足迹和人均虚拟水足迹均呈现波动增长趋势,而青海省呈现下降趋势;虚拟水足迹作为西北五省水足迹的主要贡献者,其中农产品虚拟水占虚拟水足迹的比重较大,且在研究时段内占比均有所下降;西北五省水足迹人口密度除青海略有增加以外,其他四省均表现为波动下降趋势;水足迹经济效益均呈现增长趋势,水资源压力指数除2019年的宁夏以外,其他均小于1,其中甘肃、新疆和宁夏波动升高,陕西和青海波动下降。因此,虽然西北五省水资源压力总体不高,水足迹经济效益也在逐年增加,但是人均水资源拥有量的不均衡性以及居高不下的人均水足迹使得西北五省水资源的可持续发展面临较大的威胁。
英文摘要:
      Based on the theory of water footprint, this paper calculated, analyzed and compared the water footprint of the five northwestern provinces from 2000 to 2019, and evaluated their water resources utilization status. The results showed that during the study period, the per capita water footprint and per capita virtual water footprint of Shaanxi, Gansu, Ningxia and Xinjiang in the five northwestern provinces showed a fluctuating growth trend, while Qinghai showed a downward trend;the virtual water footprint was the main contributor to the water footprint of the five northwestern provinces, among which the virtual water footprint of agricultural products accounted for a large proportion of the virtual water footprint, and the proportion had declined during the study period; the population density of water footprint in the five northwestern provinces only increased slightly in Qinghai, while the other four provinces showed a fluctuating downward trend; the economic benefits of the water footprint all showed an increasing trend, the water resources stress index were less than 1 except for Ningxia in 2019, among them the fluctuations in Gansu, Xinjiang and Ningxia increased, and the fluctuations in Shaanxi and Qinghai decreased. Therefore, although the overall pressure on water resources in the five northwestern provinces was not high, and the economic benefits of water footprint were increasing year by year,but the imbalance of per capita water resources ownership and the high of per capita water footprint made the sustainable development of water resources faced great threat in the five northwestern provinces.
