Abstract: Agroecosystem health is the fundament of food security and human health,and becoming one of the hot spots and frontier fields in agricultural ecology study with more and more international concerns,which can be interpreted as a sustainable state and a dynamic process involving good eco-environment,healthy agricultural organisms,rational spatial and temporal structure,clean production pattern,optimal biodiversity and high productivity.Agroecosystem is a kind of typical artificial and natural compound ecosystem.Its health is strongly influenced and controlled by human activities,and usually linked with agro-products quality,food security and biological security.A series of indices including biological,environmental and eco-economic indicators could be integrated to assess the situation and level of agroecosystem health,and some methods including comprehensive index assessment,eco-toxicological assessment and ecological risk assessment could be used for the evaluation of agroecosystem health.

Key words: Ecosystem health, Evaluation index, Agroecosystem
