农林复合生态系统优化模式研究——以河北省饶阳试区为例

0ptimal models of agro-forestry ecosystem—A case study from Raoyang County of Hebei Province

摘要: 研究分析了河北省饶阳试区实施5种农林复合生态系统优化模式的可行性及其经济效益、配置技术和应用条件，各模式纯收入为果园早期间作>果农间作>林农间作>林网农田>林牧结合;而产投比为果园早期间作<林农间作<果农间作<林网农田<林牧结合,为平原农区合理建立农林复台生态系统提供了科学依据。

Abstract: Feasibilities,economic benefits,configuration techniques and application connditions of optimal models of five agro-forestry ecological systerm in Raoyang Experiment Zone of Hebei Province are analysed，Their order of net income is the early fruit orchard intercropping>fruit tree-grain crop intercropping>agro-forestry intereropping>forest belts farmland>forest-animal husbandry combinational system．The ratio of output／input is adverse to the net income except agro-forestry intercropping
