农林复合系统结构设计探讨

Discuss on the Structural Design of Agroforestry Systems

农林复合系统的目标在于实现环境保护、农林业生产、农业可持续发展等。论述了农林复合系统的内涵及其结构设计的原则、方法和步骤。以生态学原则为主,充分考虑经济、社会等方面,归纳了农林复合系统结构设计的原则。依次从资料收集与调查、可行性分析及目标设计、模式结构设计、效益评价及结构调整4个步骤讨论了农林复合系统结构设计的步骤内容,重点从物种、空间、时间、营养和产品结构方面讨论了如何对农林复合系统进行结构设计。加深对农林复合系统结构的认识,进一步研究结构设计原则和方法,完善结构设计步骤和过程,对于提高系统结构设计的成功率,建立具有稳定、低成本、高产出等特征的农林复合系统,推动农业可持续发展等具有积极意义。

The goals of Agroforestry are environmental protection,agricultural and forestry production,agricultural sustainable development and so on.To discusses connotation,structural design principles,design methods and steps of Agroforestry systems in this paper.With taking ecology principle primarily,and considering fully economy and society,the design principles of Agroforestry have further induced.The steps and its content are discussed from acquisition of information and investigation,feasibility analysis and object design,configuration design,benefit appraisal and the structural adjustment.How to design Agroforestry Systems is analysisde from the species structure,space structure,time structure,nutritional structure and product structure.It have the positive sense that to understand deepening Agroforestry structure,to study further the design principle and the method,to perfect design procedure and the process,regarding enhance the success ratio of Agroforestry structure design,establish Agroforestry with characteristic stability,low cost,highly outputs,and so on,promote the agricultural sustainable development.
