关 键 词：Water resources carrying capacity Principal component analysis Tarim river basin Comprehensive evaluation
摘 要：In order to overcome the comprehensive evaluation problems on water resources carrying capacity,an idea of principal component analysis(PCA) method was presented,and the mathematical model of comprehensive evaluation was *** important single indexes,which were used for evaluating its characteristic,included irrigation rate,water use efficiency,water resource development level,water supply module,the per capita water demand and water supply module and other single-technology *** region in Tarim river basin was evaluated by using the composite *** showed the former three principal components contained 99.64% of the information for the six *** last,the composite index rank of the five region was got by the integrated *** mathematical model can be used for comprehensively evaluating the index of water resources carrying capacity and provide proofs for planning of the water resources carrying capacity.
