林农复合经营是指在同一土地经营单位上,以充分发挥林地生产潜力为目的并按生态经济学原理把林、农、牧、副、渔各业有机地组织在一起而形成的具有多种群、多层次、多功能、多效益、高产出特点的人工复合生态系统。因此,要建立一种良好的林农复合系统,既要考虑空间上的立体结构,又要考虑时间上的合理搭配,还要考虑系统内部的环境条件与种群之间的相互依托关系以及自然资源的合理利用,使其更有效地提高光能和土地资源的利用率,最大限度地发挥林地的生产潜力。由于林农(主要指粮食)复合经营是一种人工复合生态系统,因此,系统效益的好坏
The forestry-farm cooperative management refers to the operation of forestry, agriculture, animal husbandry, fishery, fishery, forestry, animal husbandry, fishery, forestry, animal husbandry, fisheries and fisheries in the same land management unit with the purpose of giving full play to the potential of forest land production and organically organized according to the principle of ecological economics. Multi-level, multi-functional, multi-benefit, high output of artificial composite ecosystem. Therefore, to establish a good system of FFCs, we should not only consider the spatial three-dimensional structure, but also take into account the reasonable collocation of time, and also consider the interdependence between environmental conditions and populations within the system as well as the natural resources Make rational use of it, make it more effectively raise the utilization rate of light energy and land resources, and maximize the productive potential of forest land. Since forest farmers (mainly food) compound management is a kind of artificial compound ecosystem, therefore, the system benefits are good or bad
