【摘要】 为深入了解珠江三角洲(简称珠三角)地区水环境承载力发展状况,更好地推进生态文明建设,从社会经济、水生态环境、水资源3个子系统中选取19项指标构成水环境承载力评价指标体系,运用熵权法和障碍度模型对2015年珠三角地区9个城市的水环境承载力和障碍指标进行评价分析。结果表明:水环境承载力综合评价指数平均值为0. 507,整体表现适中,但区域性差异显著,深圳、珠海和广州表现最好,佛山、东莞和江门相对较差;从指标障碍度分析来看,人均水资源量以9. 9%的障碍度均值成为全地区水环境承载力的首要障碍指标,各子系统障碍度也存在不同程度的空间分异性。根据珠三角地区经济发展特点提出了提高其水环境承载力的建议。

【Abstract】 To comprehensively understand the development of water environmental carrying capacity in the Pearl River Delta and better promote the construction of ecological civilization, 19 indicators were selected to construct an evaluation index system from the three subsystems of economy, water environment and water resources. Entropy weighting method and obstacle degree model were used to evaluate and analyze the carrying capacity and obstacle factors of nine cities in the Pearl River Delta in 2015. The results showed that the average evaluation index of water environmental carrying capacity was 0. 507, and the overall performance was moderate, but the regional differences were significant: Shenzhen, Zhuhai and Guangzhou had the best performance, and Foshan, Dongguan and Jiangmen had relatively low level of carrying capacity. From the analysis of obstacle degree, the freshwater resource per capita was the dominant obstacle factor affecting the water environmental carrying capacity with an obstacle degree of 9. 9%, and there were also spatial differences in the obstacle degree of each subsystem in the region.Based on the characteristics of economic development in the Pearl River Delta, corresponding suggestions for improving its water environmental carrying capacity were put forward.
