As the development of a new branch of scientce, agroforestry has an important role to play in modern production technology. From a combination of primary production of agricultureal crops and forest trees, it has become an integrated artificial ecosystem consisting of not only primary produces, but also includes secondary production components such as animal husbandry, fishery, sericulture and apiculture. In this type of deversified management system, optimal economic, ecological and social benefits can be obtained.
