厦门城市森林改造不同树种幼林生长差异分析

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。

Analysis on the Differences in the Growth of Different Species of Urban Forest in Xiamen

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 i...
