陕北佳芦河流域水资源承载力研究

Study on water resources carrying capacity of Jialu River Basin in North Shannxi Province

佳芦河流域位于我国西北干旱半干旱地区,水资源承载力的研究对当地国民经济发展规划、生态环境保护和水资源可持续利用具有重要意义。根据当地水资源开发利用状况,结合水资源、社会经济和环境系统之间的关系,将佳芦河流域水资源承载力问题纳入到自然-经济-环境这一复杂的大系统进行建模分析,从可持续发展角度建立流域水资源承载力模糊综合评价模型。评价结果可为流域今后水资源可持续开发利用提供参考和指导。

Water resources carrying capacity is an important component of natural resources carrying capacity,which is a ＂bottleneck＂ indicator to decide whether the region can support the coordinated development of population,economic and environment.The Jialu River Basin is located in arid and semi-arid areas of Northwest China,for which the research of water resources carrying capacity is of great important on guiding local economic development planning,ecological environment protection and sustainable development of water resources.According to the situation of local water resources development and utilization and relationship among water resources,socio-economic and environmental systems,we established fuzzy comprehensive evaluation model in view of sustainable development.The results provide reference for future sustainable development and utilization of local water resources.
