基于向量模法的陕南地区水环境承载力评价

在论述水环境承载力概念的基础上,结合陕南地区的水环境现状,通过构建指标体系,应用向量模法对陕南地区2000-2007年的水环境承载力进行了评价.计算结果表明,陕南地区水环境承载力的变化呈现波动趋势,但逐渐趋于平缓.并针对陕南地区的具体情况,提出了加强区域水源涵养与水源地保护、调整产业布局、加快污水处理设施建设、加大小型水利工程建设和建立水资源补偿机制等对策措施.

Evaluation of Water Environment Carrying Capacity in Southern Shaanxi Province Based on Vector Norm Method

This study is based on the concept of water environment carrying capacity and is combined with the current water environmental situation. Through the establishment of evaluation index system and the application of vector norm method,the evaluation of water environmental carrying capacity in Southern Shaanxi Provine from 2000 to 2007 are made. Results show that the change of water environmental carrying capacity has a fluctuated tendency,but becomes more and more gently. According to the specific circumstances of it,some countermeasures are proposed:strengthening regional water conservation and protecting water sources,revising industrial distribution,speeding up the construction of sewage treatment facilities,increasing small-scale water conservancy project construction,and establishing water resource compensation mechanism.
