塔里木河流域的生态环境质量综合评价研究

采用切实可行的指标体系综合评价塔里木河流域生态环境质量,对流域的近期综合治理以及其它环境建设工程都具有很强的参考和指导意义。本文结合已有的研究成果,首次运用RS／GIS技术,参考2003年中国环境监测总站颁布的《生态环境质量评价方法》。以塔里木河流域的42个县(市)为评价单元,对塔里木河流域生态环境质量进行综合评价。结果表明,整个塔里木河流域的生态环境质量属较差和差级,其中干流上游与四源流经地区环境质量略好于其它地区。天山南麓、环塔里木盆地北部及西部绿洲区的生态环境状况优于环塔里木盆地南缘的和田地区,评价结果符合实际情况。

Study on The Comprehensive Assessment of Ecological Environment Quality of Tarim River Drainage Area

The paper uses doable index system to assess ecological environment quality of Tarim river drainage area. it has reference and guidance for integrated arrangement of drainage area in the near future and other environment construction project. Based on existing research fruit, this paper uses RS/GIS first time, references "Assessment Method of Ecological Environment Quality" by national environmental monitoring station in 2003, 42 counties (cities) of Tarim river drainage area as assessment unit, comprehensively assesses ecological environment quality of Tarim river drainage area. The result shows that ecological environment quality of Tarim river drainage area is the fourth class and the fifth class, upstream of Tarim River and flowed region by 4 headstreams which environment quality is briefly better than other regions. Ecological environment quality of the south plain of Tianshan mountain and the north and the west oasis of Tarim basin is better than Hetian region of the south of Tarim basin. The result of assessment accords with practical conditions.
