摘要

构建了水资源可持续发展评价指标和预警度划分体系，选取石羊河流域15年水资源可持续利用评价指标，应用主成分分析法选择主成分和相应的方差贡献率，以主因子方差贡献率为权重。运用主因子模型对石羊河流域未来15年水资源可持续利用进行了探索性预警预测，并建立了评价指标体系。

Comprehensive evaluation on early warning of water resources sustainable utilization in Shiyang river basin based on principal components analysis

It constructed the systems that water resources sustainable development appraisal indicator and warning degree division, selected appraisal indicator of water resources sustainable utilization of 15 years in Shiyang river basin, applied principal components analysis to choose principal components and corresponding variance contribution rate, took the variance contribution rate of principal divisor as the weight. It made exploratory warning forecast for water resources sustainable utilization in Shiyang river basin in future 15 years through principal divisor model and built appraisal indicator system.
