摘　　要：笔者研究了桉农间作系统树影的变化特征,为寻找出一种桉农间作模式,促进桉树林地的可持续生产,又能在一定程度上缓解我国土地资源紧缺的矛盾。结果表明:正东西走向大宽行桉农间作模式能使系统内遮荫程度尽量地减小,能使光照资源最大程度进入农作物间作带,满足间作物对光热资源的需求。Our research aims to find an agricultural intercropping eucalyptus model, which promotes the sustainable production of eucalyptus forest, and to some extent, alleviate the shortage of land resources in China. The analysis data showed that east-west line big wide mode of eucalyptus agricultural intercropping system was as far as possible to reduce the degree of shade, and by which the sun light could enter the intercropping with crops to the greatest extent, and satisfied the need for light and heat from the crops.
