本文对湿地松引种到沙地后形态、生理、生态对沙地的适应与早期生长状况研究,认为湿地松目前是生长在该区沙地松树中最好的树种。但需采取一些造林技术措施,实现湿地松在沙地的定居。

In this paper, adaptability to sandy land and situation in early growth stage of Slash Pine were dis cussed; some technical questions of pine afforestation were analysed; successful possiblity of the pine afforestation in the area was studied.
