Through exploration of the valley located in Anhui section during the "eighth five-year plan", a traditional concept was broken through from point of view of macro-pattern, which led to a new distribution system of test region for research. The research explored three kinds of basic models as supporting main orientational industries.             长江中下游低丘型流域森林生态环境长期处于低劣化和低产化局面。＂八五＂期间通过对安徽区段的探讨，首先从宏观上突破了流域格局的传统认识。继而形成了新的试验布点研究体系。试点结果和效益分析表明，建立高效林农（副）复合体系是综合治理的有效对策，并特别考虑到在低丘建立主导产业的前景与可能，为此提供了三类基础利用模式。 文摘来源   << 更多相关文摘         相关查询: 流域型 内涝型流域 ⅱ型流域 型 生态经济型流域 流域 足型 stanford型 刺激型 pp型 钾型 舟型  对查询结果不满意
