Abstract: The KJ 85-06 was the largest ecology research project financed by the Chinese Academy of Sciences in the eighth five-year plan. Nineteen research institutions,twenty research stations and some five hundred researchers were involved in the project.The total budget of the project was ten million Chinese yuan in 1991～1995.Great progress was achieved,some four hundred and fifty papers and three monographs were published thus far,and more will be published in coming years. In this paper,some of the new findings are briefly discussed,and suggestions regarding to the research of optimum management of ecosystems and the network research of ecological process and the impact of human activities are made.

Key words: Structure and function of ecosystems, Optimum management of ecosystems, Network research of ecological process, tree-ring stable carbon isotope, tree-ring width, water use efficiency, stomatal conductance
