摘要
简要叙述了农林复合生态系统间作研究进展及农林间作系统中各生态因子的特征。归纳了国内外不同农林间作系统中光能、温度、湿度、土壤水分、风速、土壤养分以及农林间作系统的经济生态效益的研究进展。指出了农林间作系统中生态因子方面的研究不足及需要进一步研究的科学问题。提出了农林复合间作系统获得高产高效的关键技术。
In this paper,the research progress and the character of ecological factors in agroforestry was briefly described.The light,temperature,humidity,soil water content,wind speed,soil nutrition,economic and ecological benefits in agroforestry systems etc.were summarized.It indicated the advantages and disadvantages in agroforestries related to high yield and resource use.It was suggested that the agroforestry systems could improve productivity with optimizing nature resources.
