【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合生态系统提供了科学依据。更多还原

【Abstract】 Feasibilities,economic benefits, configuration techniques and application condi-tions of optimal models of five agro-forestry ecological system in Raoyang Experiment Zone of Hebei Province are analysed. Their order of net income is the early fruit orchard intercrop-ping>fruit tree-grain crop intercropping>agro-forestry intercropping>forest belts farmland>forest-animal husbandry combinational system. The ratio of output/input is adverse to the net income except agro-forestry intercropping<fruit tree-grain crop intercropping. The results provide scientific basis for the establishment of agro-forestry ecosystem in plain.更多还原
