云南热区混农林系统的分类方法与分类系统研究

A STUDY ON CLASSIFICATION OF AGROFORESTRY SYSTEMSIN YUNNAN TROPICAL AREAS

探讨混农林系统的分类方法和分类系统为混农林系统的评价与发展提供一个清晰而实用的框架。在云南热区现存混农林系统模式全面清查的基础上，以目前国际公认的混农林高等级分类系统为基本轮廓，提出了云南热区混农林系统的亚系统单位（按不同分类目的确定）、类型单位（组分构成方式和经营管理相同或相似）和模式单位（物种组成相同）三级结构分类系统，同时，按混农林系统生态区域和经营强度进行了区分。

Classification of agroforestry(AF)is necessary in order to provide a framework for evaluating AF systems and disseminating action plans for its developmemt.Based on theinventory of existing AF systems in tropical areas,Yunnan,China,and the high-gradeclassification of AF systems,this paper presents the structural classification of AF svstemsof three-grade subsystems(Depending on the purpose of classification),types(Thesame arrangements of AF components and land management)and models(The samespecies combination).In addition,ecological and management agroforestry systemshave been grouped.
