Inter-annual dynamics of grassland yields and assessment of herbage supply in the headwater region of three rivers over 18 years

摘要：

The headwater region of the Yangtze, Yellow and Lantsang rivers is one of the most important ecological function regions in China, and in eastern Asia.In recent decades, because of climate change and excessive human induced utilization, grasslands in the region have degenerated badly (Wang et al,.2005).Thus, it is necessary to analyze grassland productivity dynamics to assess changing trends of grassland supply.We discuss reasons for observed changes.This analysis will be helpful for establishing effective strategies in grassland conservation and management.
