It is a new emerging field of agro-ecosystem research. Although many researchers did many studies from different aspects,there is no consensus of its definition and no quantitative measure has been available for its assessment at present. By reviewing literatures and special investigation,this paper defines the agro-ecosystem health on a regional dimension of county level,s
