我国农林复合系统自然资源利用率研究进展

Research Progress of Natural Resource Utilization in Agroforestry System in China

农林复合系统是一种动态的自然资源管理系统,通过总结我国农林复合系统在光能、水分、养分及土地等自然资源利用率的研究进展,认为农林复合系统具有提高自然资源利用率等重要作用,只是由于气候、树种林种及其密度和林龄、作物种类的差异,使得提高的幅度有所差异而已;并从研究尺度、研究内容及方法等角度,提出研究展望。

Agroforestry system is a dynamic natural resource management system. This paper summarized the research progress of agroforestry system in the utilization of solar radiation,water,nutrition,land and other natural resources. We concluded that agroforestry system was important to improve the utilization of natural resources. However,the degree of this improvement was different due to differences in climate,forest category and tree density and stand age,crop types. The research scale,research content,method and research prospects were also proposed in this paper.
