红碱淖生态环境质量评估及对策研究

红碱淖是中国最大、最年轻的沙漠淡水湖,水域面积67平方公里。通过数据收集统计及打分计算的方式对红碱淖水环境质量、生态环境质量、水生态健康进行定量分析,结果表明,红碱淖水环境质量从1981年至2010年有逐渐恶化的趋势;2010年红碱淖生态系统健康综合指数为59.86,属于中等水平,已经受到了一定影响;生态质量综合评价值为81.6分,具有较高的保护价值。并对造成红碱淖水质和生态系统逐步恶化的原因进行解析,同时提出相应的对策。

Assessment and Countermeasures for Ecological and Environmental Quality of Hongjiannao

Hongjiannao is the largest and youngest desert freshwater lake in China with water area of 67 square kilometers. This paper analyzed water environmental quality, ecological quality and water ecological health quantificationally through data col- lection, statistics and rate calculation. The result shows that water environmental quality worsened from 1981 to 2010 and the eco- system health index was 59. 56 which belong to medium level. The ecological quality comprehensive evaluation value was 81.6 which mean the lake had high conservation value. The study proposed the reason of the deteriorating trend of Hongjiannao water and ecosystem quality, meanwhile, put forward the corresponding countermeasure.
