总结了国内外关于水贫困评价研究的现状,指出了水贫困评价中存在的问题,并对今后水贫困研究进行了展望。水贫困的现有研究成果存在以下问题:(1)水贫困的概念不确定,从而使其形成的原理机制也不明确;(2)水贫困测度模型尚不完善;(3)对评价结果的分析只限于考察评价对象在各子系统的优劣势,对进一步基于地理信息系统分析评价对象水贫困与经济贫困等方面的耦合关系及空间分异研究较少。综合目前研究进展看,未来水贫困理论在研究尺度上将向区域(流域)、社区发展。研究干旱区和半干旱区水贫困与产业结构的影响机理,对缓解水贫困程度、提高水的利用能力、探求产业最优布局具有非常重大的理论和现实意义。
Summarizes the current situation of evaluation of water poverty at home and abroad, points out the problems existing in the evaluation of water poverty and prospects the future research of water poverty. The existing research results of water poverty have the following problems: (1) The concept of water poverty is not clear, so the principle mechanism is not clear; (2) The model of water poverty measurement is not perfect; (3) The analysis is limited to examining the strengths and weaknesses of the evaluation objects in each subsystem. There are few studies on the coupling relationship and spatial differentiation of the target water poverty and economic poverty based on the analysis of GIS. According to the current research progress, in the future, the theory of water poverty will develop to the region (basin) and community in the research scale. Studying the impact mechanism of water poverty and industrial structure in arid and semi-arid areas is of great theoretical and practical significance for alleviating the degree of water poverty, improving water utilization capacity and exploring the optimal layout of industries.
