Abstract: In light of the condition of our country, this paper introduces the concepts and contents of sustainable a-griculture and its quantitative evaluation indices ──sustainability, stability,equality and harmonity(di-versity).Simplified system input—output equilibrium is used to estimate the dynamics of soil fertility.Probations at state, province,county and village levels have proved its satisfactorily feasibility.

Key words: controlled alternate partial root-zone drip irrigation, root hydraulic conductivity, apple seedling, root-shoot ratio, healthy index of seedlings.
