农林系统研究进展

综述了国内外农林系统的研究进展 ,介绍了农林系统的概念、产生背景和过程及主要的研究方向。从农林系统的结构和分类、农林系统小气候及系统效益评价等 3个方面对当前农林系统的研究现状进行了评述。重点从水分、温度、辐射、光照及人体舒适度等方面分析了农林系统小气候的研究状况 ;从化感作用和地下部分相互作用两个方面介绍了系统组分间的相互作用关系。同时指出农林系统类型较为单一、理论研究落后于实践、基础理论研究相对薄弱等研究中存在的问题。提出农林系统的研究应进一步加强多学科深层次、实质性的交流与合作 ,注重科研机构与生产基层的有机联系 ,加强理论基础研究 ,因地制宜地发展农林系统 ,更好地为生产实践服务。

Research progress in agroforestry systems

In this paper, the research progress in agroforestry systems was summarized. The concept of agroforestry and its background, the process of development and the main research fields of agroforestry were introduced. The review was based on such aspects as the structure and classification, microclimate, benefit evaluation and so on. The microclimate was emphasized on water, temperature, radialization, solar radiation and comfortableness, and the interaction among the partitions was introduced .Then the existing problems in agroforestry development were pointed out such as the shortness of types, the fact that the theory research cannot keep up with the production, etc. The development prospects and advices were finally brought forward.
