青海湖生态价值与生态环境保护研究

Researches on ecological value and protection of ecological environment of Qinghai Lake

青海湖具有重要的生态价值,它既维系着青藏高原东北部的生态安全,是阻挡西部荒漠化向东蔓延的天然屏障,又是青藏高原生物物种的宝库和"青藏高原基因库"。因此,研究和保护青海湖具有重要意义。通过了解青海湖生态环境变迁的历史,探索青海湖生态环境恶化的原因,提出了保护青海湖生态环境的对策:在青海湖流域圈定"无人居住区";引用外部水源增加湖容量;采取措施控制水污染。

Qinghai Lake is of important ecological value.Not only it maintains the ecological safety of the northeast part of Qinghai-Tibet Plateau and is the natural barrier of desertification towards the east,but also it is the treasure house of biologic species and the gene bank of Qinghai-Tibet Plateau.Therefore, researches on and protection of Qinghai Lake are of important significance.Through the evolution of its ecological environment,the causes for the deterioration of ecological environment of Qinghai Lake are discussed,and thus some countermeasures are put forward: determination of the uninhabited area in the basin of Qinghai Lake;increase of capacity of Qinghai Lake by introducing external water sources;implementation of measures to control water pollution.
