摘要
地处青藏高原的黄河源区近年来生态环境不断恶化 ,以植被退化、土地荒漠化、水土流失、冰川退缩、湖泊萎缩、湿地退化、生物多样性下降为代表。本文对这些生态环境问题进行了定量的论述 。
The source region of the Yellow River is located in the centre of the Qinghai-Tibet plateau. In recent years, the eco-environment is characterized by grassland degeneration, land desertification, soil erosion, glacier shrinkage, lake contraction, wetlands degradation, and biodiversity decrease. These changes are analysed in this paper. It is suggested that a comprehensive renovation should be taken to protect, restore and improve the forest and grassland system.
