Abstract

Abstract: Index of biological integrity (IBI) has been proved to be one of the useful measures in health assessment of aquatic ecosystem, and is widely applied today. In this paper, the concept of IBI, its philosophy and steps in health assessment of aquatic ecosystem, and the built-up of benthic-index of biological integrity (B-IBI) were generalized, and the performances of IBI applied for the health assessment and management of ecosystem in foreign countries were illustrated. The practice of IBI in health assessment of our aquatic ecosystem was also suggested.

Key words: Rice, Cultivating fish in rice field, Symbiotic effect
