摘　　要：本文在对曹老集示范良种场种养加复合生态系统进行全面调查和系统分析的基础上,明确系统发展指导思想及各业发展方向,调整生态位,增加食物链,完善生态农业模式;采用动态仿真模型作为主模型,结合有关经济预测模型、目标规划模型,对农场自然和社会、经济资源进行全面规划,优化系统结构,建立生态农业系统发展诸方案;实施方案经两年初步运行,系统生产力增强,生态经济效益显著。According to investigation and analysis on the planting-raising-processing ecosystem of Caolaoji Seed Farm, the development of ecoagricultural system should be made by adjusting ccologic niche, expanding food chain, perfecting ecoagriculture model. The SD model is used as major model. The relevant economic prophesing model and aim programme model are combined into the model. The natural, social and economic resources of the farm are programmed, optimum system structure is sought and plans of ecoagriculture system development is set up.
