【摘要】：以人均水资源占有量低、水资源利用结构不平衡省份山东省为研究区,首先计算2005—2014年山东省水足迹及2014年17地市水足迹,实现水足迹时空分析;从DPSIR视角出发,基于水足迹计算结果,融合构建水资源可持续利用评价指标体系,通过因子综合得分来反映全省10 a间水资源可持续利用强度,以2014年为水平年,对17地市因子综合得分进行空间聚类,实现水资源可持续利用时空分析。结果表明:研究区2005—2014年水资源可持续利用综合评价得分呈现增长态势,表明水资源可持续利用程度趋于加强,但分值总体较低,仍需提高利用效率;2014年17地市水资源可持续利用水平整体呈现东优西劣、南优北劣的空间格局。
[Abstract]:Taking Shandong Province, a province with low water resources per capita and unbalanced water resources utilization structure, as the research area, the water footprint of Shandong Province from 2005 to 2014 and the water footprint of 17 cities in 2014 are calculated firstly, and the spatio-temporal analysis of water footprint is realized from the perspective of DPSIR.Based on the results of water footprint calculation, the evaluation index system of sustainable utilization of water resources was constructed, and the intensity of sustainable utilization of water resources was reflected by comprehensive score of factors, taking 2014 as the level year.Spatial clustering was carried out on the comprehensive scores of 17 prefectures and cities in order to realize spatiotemporal analysis of sustainable utilization of water resources.The results show that the comprehensive evaluation scores of sustainable utilization of water resources in the study area from 2005 to 2014 show an increasing trend, indicating that the degree of sustainable use of water resources tends to strengthen, but the overall score is relatively low.In 2014, the sustainable utilization level of water resources in 17 prefectures presented the spatial pattern of east superior and west inferior, south superior and northern inferior.
