摘　　要：在测试并确定农业生态系统各项参数和状态变量的基础上， 应用数学模型方法建立了松嫩平原玉米带农业生态系统的能流型， 进行了结构与功能的分析， 探讨了不同农业技术模式、土壤有机质和农田产量之间消长的关系。结果认为， 实现农业的持续发展， 应采取有机无机相结合的农业技术体系。An energy flow model of corn-belt agro-ecosystem in the Song-nen Plain is constructed and calibrated. Analyses of the model indicated several possible management regimes that can result in both a sustainable yield and sustainable soil organic matter level. The model shows that primary production in the corn-belt agro-ecosystems is the energy base for self-maintenance of the system. Sustainable agro-ecosystems were sought through the optimization of the model, which are variable approaches in the corn-belt agro-ecosystem in the Song-nen Plain$$$$
