Study on Water Resources Carrying Capacity in Weifang City Based on Principal Component Analysis

In order to explore the water resources carrying capacity in Weilang City, tlae aumor cnose tilt： method of principal component analysis, selected 13 indexes, and the evaluation index system of water resources carrying capacity were established, then evaluated and researched the water resources carrying capacity in Weifang City through the two principal components. The results showed that： （1） the principal component analysis was better method for evaluating and researching the water resources carrying capacity; （2） The demographic situation, socio-econornic status and degree of water resources exploitation and using were the main factors affecting water resources carrying capacity; （3） As a whole, from 2000 to 2010, water resource carrying capacity in Weifang City was on the positive tendency. Due to the evaluated result of this study was better, so the result was as theory reference for the sustainable exploitation and using of water resources was viable.
