Principles of ecosystem and sustainable agriculture

Abstract

Abstract: Several agricultural ecosystem principles such as the law of energy flow and matter cycle,correlation of ecosystems,symbiosis and allelopathy,tolerance limit,structure and function,ecosystem opening,limiting factors,integrated function of ecosystem,biological competition and competitive exclusion,etc.,are discussed in this paper.It is suggested that Chinese ecological agriculture is a kind of typical sustainable agricultural system,and should be powerfully carried out in the course of national sustainable agricultural development.

Key words: Ecosystem, Ecological agriculture, Sustainable development, ecosystem assets, ecosystem accounting, ecosystem services
