摘　　要：对厦门城市森林改造后的林分,测定不同光照强度、不同土壤条件下套种树种的生长情况,结果表明：无论是耐荫还是喜光树种,幼林在相对光强大的位置的生长比光强小的地方好;而不同土壤条件下树高生长差异不明显。说明采用林冠下套种改造,需要先进行适当的间伐,使相对光照强度提高到40%-50%以上,林冠下套种树种才能正常生长。The urban forest stands, whose interplanting species growth under different light intensities and different soil conditions was measured, were rebuilt in Xiamen. The results showed that： tolerant and light-loving young plants lived better at the position with strong light than at the position with weak light; the plant height growth difference wasn＇t evident under different soil conditions, which showed that a proper thinning should be conducted first for interplanting under the canopy, so the relatively light intensity raised to 40--50 96 and more, the tree species being interplanted under the canopy could live normally.
