摘要
为充分了解山西省水资源利用现状及变化趋势。基于水足迹理论分析了山西省及其各行政区2007-2016年的水资源利用状况,探讨了水资源配置和利用的时空变化特征,并结合协调发展脱钩评价模型对山西省水资源利用与经济增长协调发展进行评价。结果表明:①近十年来山西省水足迹总体呈现上升趋势,各行政区之间差异显著,其中运城市水足迹值最高,阳泉市最低。全省多年人均水足迹平均值为731.22 m^3/人。②水足迹结构在研究时限内基本稳定,农业水足迹占比一直保持在90%左右,工业用水小幅下降,生活、生态用水小幅上升。③山西省水资源自给率水平非常高,平均值为98.97%。除太原市外,其他地区水资源自给率均保持在97%以上。④山西省水足迹经济效益由2007年的28.13元/m^3上升到2016年的43.23元/m^3,各行政区10年间水足迹经济效益均有不同程度的提高。⑤10年间山西省各行政区的水资源压力指数均大于1,整体水资源压力指数由2007年的1.96上升到2016年的2.24,说明山西省水资源利用长期处于不安全状态,且地区差异明显。⑥山西省经济增长与水资源利用之间除2013年、2014年外均表现为协调关系。
In order to fully understand the current situation and changing trend of water resources utilization in Shanxi Province.Based on the water footprint theory,this paper analyzes the situation of water resources utilization in Shanxi Province and its administrative regions from 2007 to 2016,discusses the spatial-temporal variation characteristics of water resources allocation and utilization,and evaluates the coordinated development of water resources utilization and economic growth in Shanxi Province based on the decoupling evaluation model of coordinated development.The results show that:①the water footprint of Shanxi Province is on the rise in recent ten years,and there are significant differences among different administrative regions.Among them,the water footprint of Yuncheng city is the highest,while that of Yangquan city is the lowest.The average annual per capita water footprint is 731.22 m^3/person.②the water footprint structure was basically stable within the time limit of the study,the proportion of agricultural water footprint remained at about 90%,the industrial water use declined slightly,and the domestic and ecological water use increased slightly.③the water resource self-sufficiency rate of Shanxi Province is very high,with an average of 98.97%.Except Taiyuan,the water resources self-sufficiency rate in other areas are kept above 97%.④the economic benefit of water footprint in Shanxi Province increased from 28.13 yuan/m^3 in 2007 to 43.23 yuan/m^3 in 2016,and the economic benefit of water footprint in each administrative region increased to different degrees in 10 years.⑤in the past 10 years,the water resource pressure index of each administrative region of Shanxi Province was greater than 1,and the overall water resource pressure index rose from 1.96 in 2007 to 2.24 in 2016,indicating that the water resource utilization of Shanxi Province was in a state of long-term insecurity with obvious regional differences.(6)the relationship between economic growth and water resource utilization in Shanxi Province is coordinated except in 2013 and 2014.
