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。
On the basis of testing and determining various parameters and state variables of agroecosystem, the energy flow model of agroecosystem of maize belt in Songnen Plain was established by using mathematical model method, and the structure and function of agroecosystem in Songnen Plain were analyzed. The effects of different agricultural technology models , The relationship between soil organic matter and crop yield and growth. The results show that to achieve the sustainable development of agriculture, we should adopt the organic and inorganic agricultural technology system.
