根据对华北地区水资源短缺最严重的滏阳河流域的实证研究表明,随着部门和上下游用水者之间用水竞争程度的加剧,流域从开放向闭合的转变,地下水位的逐年下降及引致的环境问题,节水的空间也变得十分有限。解决未来水资源短缺的问题很大程度上将依赖于如何运用政策、制度和经济措施实现水资源的优化配置和综合管理,提高灌区的运行绩效和实现有效的产权制度创新。 According to the empirical study of the Fuyang River basin, which has the worst water shortage in North China, it shows that with the intensification of water competition between departments and upstream and downstream water users, the basin’s shift from open to closed, the declining groundwater table and the consequent The environmental issues, water-saving space has become very limited. To solve the problem of water shortage in the future will depend largely on how to use the policies, systems and economic measures to achieve the optimal allocation of water resources and integrated management, improve the operational performance of irrigation districts and achieve an effective property system innovation.
