基于DPSIRM概念框架模型的岩溶区水资源安全评价

针对目前水资源安全评价中存在的评价指标片面性、单个指标隶属信息遗漏及权重确定主观性问题,以岩溶典型区-贵州省为例,结合岩溶地区水资源的特点,构建基于驱动力-压力-状态-影响-响应-管理(DPSIRM)概念框架的岩溶区水资源安全DPSIRM评价指标体系,借助灰色-集对模型对贵州省2005~2012年水资源安全进行定量评价,研究结果表明: 2005和2006年整个贵州省水资源安全处于临界安全状态,2007~2012年处于较安全状态,贵州省水资源安全呈现整体转好的态势.水资源的状态和水资源管理是目前影响贵州省水资源安全的重要因素;因此,在继续调整经济结构转变增长方式同时,提高水资源的利用效率,加大水资源基础设施建设的投入,加强水资源管理制度建设和提高水资源管理制度的落实情况,是贵州省水资源安全的根本保障;该评价模型和指标体系适用性较强,评价结果较为客观,为岩溶地区水资源安全评价提供了一个新视角和新方法.

The safety evaluation of water resources based on DPSIRM conceptual framework in karst region

Aiming at the problems existing in the safety evaluation of water resources, such as partial evaluation indexes, the omission of single index membership information and subjectivity problem of determining weight, In a typical karst area-Guizhou province as an example, combining with the characteristics of water resources in karst region, based on conceptual framework of driving force-pressure-state-impact-response-management (DPSIRM) to build evaluation index system of water resources security, with the help of grey-set pair model to make quantitative evaluation of Water security of Guizhou province in 2005~2005, The results show that: the water security in Guizhou in 2005 and 2006 in the criticality safety state, 2007~2012 in a safe state, water security in Guizhou to present the overall good posture. the state of water resources and water resources management ware the important factors affecting the safety of water resources. Continued to adjust the economic structure and transformation of the mode of growth at the same time, improve the utilization efficiency of water resources, increase investment in infrastructure construction of water resources, strengthening the construction of water resources management system and improve the implementation of water resources management system, these were the fundamental guarantee of the water security in Guizhou; The applicability of the evaluation model and index system was stronger, the evaluation results more objective, provided a new perspective and a new method for the safety assessment of water resources in karst region.
