| 摘 要： | 城市水资源安全对保障城市和地区的可持续发展起着至关重要的作用,是城市生态安全研究的重要内容之一。文章利用环境系统评价中广泛使用的“驱动力-压力-状态-影响-响应”概念框架（DPSIR）,结合内陆河流域水资源供需调配、水质污染控制以及水资源安全管理理论,从系统动力学的角度出发,构建了流域水资源安全评价DPSIR框架,并以黑河流域中游张掖市甘州区为例,建立水资源系统变化的驱动因素、压力、影响以及人类活动的数学模型,定量分析水资源系统人1：7-经济-水资源之间的相互作用和反馈机制。结果显示：从2002年到2007张掖市甘州区水资源系统总体趋于良性循环;人口增长、社会经济发展、工、农业用水量的增长是引起城市水资源系统压力的主要因素;工业污水、生活污水是造成水资源系统恶化的主要因素。文章最后依据DPSIR模型中关键性控制指标,提取了影响城市水资源系统的主要可调控参数,以期为城市水资源的管理提供理论依据。

| Abstract: | Urban water security is an important part of urban ecological security, and it plays an important role in the sustainable urbanization development process of city and region. Using the framework of "driving force-pressure-state-impact-response"(DPSIR)and combining the theories of water supply allocation, water pollution control and water security management of continental rivers, this paper has constructed a DPSIR framework of river basin water resources management from the point of view of system dynamics. From the perspective of systematic analysis, the model is a concept model of evaluation index system that is extensively used in environmental research as well as a general frame that is used to organize information about environmental status. By taking the middle reaches of Heho in Zhangye City as an example, this paper has established a mathematical model of driving factors, pressure, influence and human activity of water resources system changes, and quantitatively analyzed the interaction among population-economy-water resources of water resources system and the feedback mechanism. The results show that, from 2000 to 2007, the water system of Zhangye city tended to be a virtuous cycle; the main driving forces of deterioration of water resources system are population growth, social and economic development, and the enormous pressure on water resources system is caused by increases of agricultural and industrial water demand, and the aggravation of industrial and living water pollution. Finally, according to results of the analysis, the main adjustable indicators in the management of water resources in a town have been proposed, thus providing a theory basis for the management of city water resources. However, the research also has shortages and needs to be improved in the following aspects: 1) Explain further the relationship among ingredients of DPSIR model, build a more detailed model of the system, and use the statistical data of water resources to predict the trend of city water safety; 2) Establish a model platform of safety warning of urban water resources to control and test the changes of city water resources system, and provide timely reasonable scientific basis for the management of urban water resources security system. |
