珠江片水环境承载力评价研究
Evaluation of Water Environment Carrying Capacity in the Pearl River Basin
-
摘要: 以珠江片水域为研究对象,在梳理国内外相关文献的基础上,针对珠江片现有水资源环境与社会发展关系情况,构建了珠江片水环境承载力评价指标体系,而后采用变异系数法客观确定指标权重,再运用向量模法对珠江片水环境承载力进行评价,揭示并分析了近年珠江片水环境承载力的变化趋势。结果表明,2006~2014年间珠江片水环境承载力呈缓慢持续上升趋势,承载力水平值介于0.04~0.06之间,说明珠江片水环境承载力仍处于较低水平。Abstract: In this paper, the Pearl River Basin was taken as the study target. On the basis of collecting the domestic and foreign literatures of water environment carrying capacity, with regard to the existing relation status between water resource environment and social development, an evaluation index system of water environment carrying capacity was established. Then, coefficient of variation method was adopted to objectively identify the indicator weight. Vector norm method was used to assess the water environment carrying capacity in the Pearl River Basin with the variation trend in the recent years revealed and analyzed. The results showed that the water environment carrying capacity in the Pearl River Basin had a slow rising tendency from 2006 to 2014 with the level value varied from 0.04 to 0.06, indicating that the water environment carrying capacity was still at a lower level.
