摘　　要：研究干旱区水资源可持续利用变化对保障水资源、水资源和生态环境的可持续发展具有重要意义。为了全面了解和田地区水资源可持续利用的发展水平及其发展的主要障碍,本文从水资源系统压力、状态和响应能力三个方面构建了基于“PRS”模型的和田地区水资源可持续利用评价模型。基于TOPSIS算法和障碍度模型,揭示了水资源可持续利用的演化特征和障碍因素。结果表明:(1)2000—2020年,和田地区水资源可持续利用呈波动上升趋势,计算值主要在0.4~0.8之间;(2)从水资源系统压力、状态和响应的角度看,2000—2020年和田地区水资源状态、响应水平和压力水平呈波动上升趋势,其增加值分别为0.589、0.400和0.674。其中,水资源系统压力紧密度增加最多,约为2倍;(3)和田地区水资源的可持续利用主要受蒸发变化率和植被覆盖度的影响。总体而言,应调整产业结构,严格控制污水排放和水资源开发利用,提高水资源利用率和经济效益,从整体上提高水资源的可持续利用水平。It is of great significance to study the changes of sustainable use of water resources in arid areas to ensure the sustainable development of water resources,water resources and ecological environment.In order to fully understand the development level of sustainable utilization of water resources in Hotan area and the main obstacles to its development,this paper constructs an evaluation model of sustainable utilization of water resources in Hotan area based on"PRS"model from three aspects,such as pressure,state and response ability of water resources system.Based on TOPSIS algorithm and obstacle degree model,the evolution characteristics and obstacle factors of sustainable use of water resources were revealed.The result show that:(1)From 2000 to 2020,the sustainable utilization of water resources in Hotan area shows a fluctuating upward trend,and the calculated value is mainly 0.4-0.8;(2)From the perspective of water resources system pressure,state and response,the state,response level and pressure level of water resources in Hotan area show a fluctuating upward trend from 2000 to 2020,and their added values are 0.589,0.400 and 0.674,respectively.Among them,the closeness degree of water resources system pressure increases the most,about 2 times.(3)The sustainable utilization of water resources in Hotan was mainly affected by evaporation change rate and vegetation coverage rate.Overall,the industrial structure should be adjusted,the discharge of sewage and the development and utilization of water resources should be strictly controlled,the utilization rate and economic benefits of water resources should be improved,and the sustainable utilization of water resources should be improved as a whole.
