| 摘 要： | 由于人口的增长,人们对粮食、烧柴的需求与日俱增,致使森林面积减少,土壤等自然资源退化,生态环境恶化。对此于20世纪70年代提出了“复合农林业(Agroforestry)”,并发展成一门新兴的学科。它有意识地将多年生木本植物与农作物或家畜结合起来,在为农村提供烧柴、木材、饲料、粮食的同时,又可保持土壤肥力,达到持久农业的目的。它对我国大面积山丘地区自然资源的综合利用与保护有着重要的意义。

| Abstract: | Agroforestry is an approach to land use based on integrating trees and shrubs intocrop and livestock production systems.It has the potential to provide rural householdswith food,fodder,fuelwood and other tree,crop and animal products.At the sametime,it can help ensure the sustained productivity of the natural resource by enhan-cing soil fertility,controlling erosion and improving the microclimate of crop lands.It has great potential to improve the utilization and protection of hilly and mountainousregions which cover about 65% of the country in China. |
