Main points on planning of the two considerable eco-functional protection areas located in western China

Abstract

Abstract: In this paper, some focus problems were analyzed in two establishing considerable ecos-functional protection areas, the upstream district of the Yellow river and the Tarlim river watershed district. Amulti-perspective description method of ecosystems was addressed. The main environmental problems and the possible reasons causing these problems at the two regions were also examined. Finally the dominant eco-function of the protection areas was determined and some suggestions were given.

Key words: Life history, Population regulation, Immunocompetence, Trade-off
