The Ecosystem Function of Biodiversity
LIU Feng HE Jin-Sheng CHEN Wei-Lie
(1n.stbrd.e of hy, 27w Chinese A&y qf Seiersoes , Beijing 100093)
Abstract This review is about the effects of biodiversity on ecosystem functions and services. It fo-
cuses on the following parts: 1. hypotheses about different roles of different species in the ecosystem
and how biodiversity dects ecosystem functions; 2. relations between biodiversity and stability of
ecosystem; 3. how the biodiversity dects production of ecosystem; 4. the relation between biodiver-
sity and sustainability of the ecosystem. Several problems for further research are also pointed out.
Key words Biodiversity, Ecosystem function
