摘要
本文就目前发展中国家在农林系统的概念,农林作物组分的选择及其组合原理和成果,农林系统在提供多种农产品,改善生态环境,水土保持,提高土壤肥力,提供能源、饲科、覆盖物及经济效益等方面的作用和实践效果作了分析和比较,并列出了国外在农林系统的研究与实践中常用的、具有多种功能的29属57个物种。作者认为,在我国有必要进一步拓宽农林作物组分及多样化农林系统的调查与研究;各组分及农林系统生态功能的研究;开展多学科合作研究。
A review was made on concepts of agroforestry, principles and findings in selection of plant species component and their arrangements in agroforestry systems, and functions and practical effects of agroforestry in providing a variety of agricultural products, energy, fodder, and mulching materials,improving ecological environment and soil fertility conservation of soil and water,enhancing economic efficiency in developping countries. A list of 57 species in 29 genera which were considered to have multiple functions and often used in research or successfully applied to actual agroforestry systems was given in the paper. The author suggested that it is necessary in China to make more investigations and deep researches on potential plant components and diversified agroforestry systems and on ecological functions of each component and the system as a whole, and to do multidis-ciplinary cooperative research.
