长治市水资源利用的时空变化特征研究

Study on the Characteristics of Temporal and Spatial Changes of Water Resources Utilization in Changzhi City

基于2013—2017年的长治市水资源数据,对水资源利用的时空变化特征进行分析。结果表明:随着时间的变化,水资源总量的减少幅度大于用水总量的减少幅度,水资源供需矛盾日益突出;在用水结构中农业用水占比最高,年际间用水结构呈“三增一降”的形态;沁源县水资源利用相对变化率最大,潞城区的水资源利用相对变化率最小。研究结果对于分析长治市水资源开发利用提供参考。

Based on the water resources data of Changzhi City from 2013 to 2017,the characteristics of temporal and spatial changes in water resource utilization are analyzed.The results show that with the change of time,the reduction of total water resources is greater than the reduction of total water consumption,and the contradiction between water supply and demand has become increasingly prominent;agricultural water use accounts for the highest proportion in the water use structure,and the inter-annual water use structure shows the form of“three increases and one decrease”,the relative change rate of water resource utilization in Qinyuan County is the largest,and the relative change rate of water resource utilization in Lucheng District is the smallest.The research results provide references for analyzing the development and utilization of water resources in Changzhi City.
