基于主成分分析的东江流域水资源承载能力评价

Assessment of Water Resources Carrying Capacity Based on Principal Component Analysis in Dongjiang River Basin

本文分别介绍了主成分分析法的原理和算法,并将其运用到东江流域水资源承载能力评价中,并且与模糊综合评价结果进行比较。结果表明:两评价方法的评价结果都是东江流域水资源承载能力呈现中上游高下游低的分布趋势,对此提出水资源可持续利用的对策,以促进流域水资源与社会经济的协调发展。

This paper introduced the principle and algorithm of principal component analysis method, and then performed this com- prehensive assessment method on water resources carrying capacity in Dongjiang River Basin. At the same time, the results between principal component analysis and fuzzy comprehensive assessment in water resources carrying capacity of the Dongjiang River Basin were compared. The results show that evaluation results of the two methods are same, which is the current water resources carry- ing capacity higher in middle reaches and upper course, lower in the lower reaches. Therefore, the measures have been put forward for water resources sustainable utilization to make the sustainable development between water resources and social economy.
