The status of ecoenvironment of northeast regions of Yangtze, Yellow and Yalu Tsangpo rivers and protecting strategies

A conclusion for the status of ecoenvironment of Yangtze, Yellow and Yalu Tsangpo rivers source region was obtained after studying by field investigation and interview to local herdsmen. Nowadays, the grassland has degraded entirely. The main reason is overgrazing for longterms, followed by rats, freezing and thawing, and erosions by water and wind. Besides, human activities and global warming promote the speed of degradation. Strategies and some advices were proposed for protecting ecological system and sustainable development for four counties of this region.
