摘要
The research results show that diversity at the scale of Holdridge life zone observation has had a decreasing trend since the 1950s, and the ecological environment has become considerably unstable in China. The phenomena of unstable environment include continuous expansion of calamity areas since the 1950s, the seldom-seen flood that occurred in the summer of 1998 and the seldom-seen sand and dust weather that occurred in the spring of 2000. Both human activities and climate change are driving forces of the decrease in diversity and increasingly unstable environment in China. (C) 2001 Elsevier Science B.V. All rights reserved.
