基于改进关联分析模型的塔里木河流域水资源承载力评价

Assessment of Bearing Capacity of Water Resources in Tarim River Catchment Based on Improved Relational Analysis Model

针对水资源承载力评价指标间模糊且相互关联的特点,在综合考虑从优隶属度和灰色关联的基础上,提出了改进灰色关联模糊评价法,并以新疆塔里木河流域为例,验证该模型的可行性,结果表明:该模型可以有效减少评价过程中的主观因素干扰,能全面、客观地对区域水资源承载力状况作出评价。

Aiming at the features of the assessment index of bearing capacity of water recourses being fuzzy and related mutually,improvement of the gray relational fuzzy assessment method is raised in consideration of the membership degree and the gray relation. With the case of the Tarim River catchment,the model feasibility is verified. The study shows that this model can effectively decrease interference of subjective factors and fully and subjectively assess the bearing capacity of the regional water resources.
