幸福珠江优质水资源评价指标体系研究——以广东省为例

Research of the evaluation index system of high-quality water resources in the Happy Pearl River: Taking Guangdong Province as an example

为科学评价珠江现状水资源状况,构建目标层、准则层和指标层3级层次的幸福珠江优质水资源评价指标体系并建立评价模型。通过变异系数法确定指标权重,利用加权平均法计算优质水资源综合得分,根据得分评判等级。以珠江流域最具代表性的广东省为例,对建立的优质水资源评价模型进行验证应用。结果表明:广东省现状水资源优质状况总体一般,各地区水资源问题各异,与地方实际情况相符,说明所建立的评价模型具有可行性。评价成果及建议对广东省进一步加强优质水资源建设工作具有参考意义。

In order to scientifically evaluate the current water resources status of the Pearl River, a three-level evaluation index system of high-quality water resources in the Happy Pearl River is constructed and an evaluation model is established. Each index weight is determined by the coefficient of variation method, and the comprehensive score of high-quality water resources is calculated using the weighted average method, based on which, the grade of the water resources is categorized. Guangdong Province, which is the most representative area in the Pearl River Basin, is taken as an example to verify the application of the proposed high-quality water resources evaluation model. The results show that the current high-quality water resources in Guangdong Province are generally not good, and the water resources problems in different regions varies greatly, which is consistent with the actual local conditions, indicating that the proposed evaluation model is feasible. The evaluation results and suggestions can provide some reference for the further construction of high-quality water resources in Guangdong Province.
