张掖地区水资源利用现状及变化特征分析
Analysis of the current situation and change characteristics of water resources utilization in the Zhangye region
摘要
Abstract
As a typical representative oasis area in the middle reaches of the Heihe River,the Zhangye region is of critical importance for studying the current status and changing patterns of its water resources development and utilization.Taking 2023 as the base year,this study analyzed the water supply,water use,water consumption,and their changing characteristics in Zhangye City based on data from the Gansu Province Water Resources Bulletins for the period 2000-2023.The results show that in 2023,the city's water supply was mainly derived from surface water and groundwater,with very limited use of unconventional water sources.Total water use matched total water supply,and the water use system was heavily dependent on agricultural water,while industrial,domestic,and ecological water use remained relatively low.Overall water resource depletion was relatively high.From 2000 to 2023,total water use exhibited a trend of"fluctuation-stability-decline-recovery."The proportion of agricultural water use showed no significant change,domestic water use increased slightly,and industrial water use first rose and then declined.The study indicates that the city faces problems such as an imbalanced water supply structure and rigid water use patterns.It is recommended to optimize agricultural water use,promote water-saving technologies,and expand the utilization of unconventional water sources.关键词
