摘要
根据在京郊窦店村积累的资料,采用改进了的能、物流分析等方法,对该村农业生态系统进行了诊断、评价并提出对策。
Based on a lot of data accumulated on agro-ecology at Doudian Village
after it has been modernized in agricultural production,a systematic ana-
lysis including“prognosis”,evaluation and decision making has been inple-
mented,through an improved program of analysis on substance flow and
energy flow,as well as other advenced analytic methods.They may provide
an effective model by means of such a foresighted study which can be ta-
ken as a guidance to the places of the same kind in this country.
