摘要
研究基于水权管理的水资源可持续承载力。通过总结众多研究成果,以水权管理为基础,根据水资源承载力、水资源优化配置和可持续发展3者间的内在联系,界定了水资源可持续承载力的概念,构建了水资源可持续承载力科学测算的3个子模型:(1)基于水权理论的水资源配置模型;(2)基于系统层析分析模糊优选理论的水资源配置方案优选模型;(3)水资源可持续承载力计算模型。利用模型对甘肃省石羊河流域民勤县的水资源可持续承载力进行评价,结果显示:2020年最优水权配置方案下水资源支持民勤县人口、工业可持续发展的承载容量指标与已有成果相比分别增加2.02%和10.94%,次优方案下分别增加1.16%和4.30%。测算模型具有可靠性与实用性,可用于模拟不同水权管理情景下水资源可持续承载力的测算和评价。
Water resources carrying capacity is an important basis for water resources evaluation, management and planning. According to the research findings of predecessors, a new definition and model are proposed for calculating sustainable water resources carrying capacity scientifically. The models include water allocation model based on water rights management, optimal seeking model for water resources allocation scenarios, calculation model for sustainable carrying capacity of water resources. The models can reflect the intrinsic links of water resources carrying capacity, optimal allocation and sustainable development from the perspective of water rights management. This paper applies the models to evaluating the sustainable carrying capacity of water resources in Minqin Country of Shiyang River Basin. The results show that water resources capacity indexes can support the sustainable development of population and industry. They will increase by 2.02% and 10.94% for optimum scenario in 2020. Correspondingly, the results of suboptimum scenario have increased by 1.16% and 4.30%. The model is reliable and practicable, which can be used to calculate the sustainable capacity of water resources under the situation of water rights management.
