摘要
本文阐述了西北干旱地区湖泊变化的概况,论证了引起变化的原因,并分析了湖泊变化对湖区环境的影响:气候日益恶化,沙漠化面积扩大,林带消失、植被衰退,鱼类资源增殖受阻、产量下降。此外,还结合变化原因,提出了相应的治理建议。
Recent lake changes in the arid area of Northwest China are described, and the causes of the changes are discussed. It is found that these changes have some impacts on environment and ecosystems of lakes, including deterioration of climatic conditions, extension of desert area, disappearance of forest, regression of vegetation cover, and reduction of fishing yield caused by the impeded fishs breeding. Besides, considering the causes of lake changes, some suggestions and measures to prevent further changes of these lakes are proposed.
