陕西渭河流域水污染经济损失估算

Estimation on Economic Loss of Water Pollution in Weihe River Basin in Shaanxi Province

污染价值损失核算对掌握流域水污染状况、制定科学合理的治理对策具有重要意义。在对渭河干流水质监测数据分析处理的基础上,构建污染价值损失估算模型,对陕西渭河流域水污染经济损失进行估算。结果表明:渭河水体生态环境正逐步改善,但仍然存在极大的提升空间;其中宝鸡市水体生态环境较好,水资源充足,需继续保持;咸阳市水资源总量较少,水体环境仍需提高;西安市水污染问题十分严峻,必须引起足够重视并进行针对性治理;渭南市水污染损失有逐年增加趋势,需加大监管力度。可为渭河流域治理提供参考借鉴。

The calculation of pollution value loss is of great significance to grasp the water pollution situation in the basin and drew up the relative scientific and reasonable control-countermeasures. The article is based on analyzing and processing the water quality monitoring data of the mainstream of the Weihe River, the pollution value loss estimation model is constructed to estimate the economic loss of water pollution in the Weihe River Basin of Shaanxi Province. The results show that the ecological environment of the Weihe River is gradually improving, but there is still room for improvement. The ecological environment of Baoji City is better, the water resources are sufficient, and it needs to be maintained. The total water resources in Xianyang City are small, and the water environment still needs to be maintained. The water pollution problem in Xi’an is very serious, and it must be paid more attention and planned treatment. The water pollution loss in Weinan City is increasing year by year, and it is necessary to increase supervision and management strengthen. The above analysis can provide reference for the management of the Weihe River Basin.
