| 摘 要： | 毛乌素沙地防护林结构的研究结果表明,樟子松纯林的直径和树高结构均比混交林结构有规律,且符合一般树种的变化规律。在叶层结构中,樟子松纯林和林带的叶层峰值比混交林和油松林带的叶层峰值出现的树高较低,且随着树高的增加而缓慢的减小,构成较厚的叶层。所以该地区应积极发展樟子松片状或带状林的营造建设,提高樟子松林的生态效益。

| Abstract: | The results of investigation on the structure of the protective forest belt in sandy area in Maowusu indicate that the structures of the diameter at breast height(DBH)and the height of pure forest of Pinus sylvestris var. are more regular than those of the mixed forest. And it coincides with the changing rule of general species. The crown of the Pinus sylvestris var. is lower than that of mixed forest and P. tabulaeformis. And it decreases with the height of the tree increasing, forming a thick tree crown. According to the analysis, the forest square or the forest belt of the pinus sylvestris var. should be developed in order to improve the ecological efficiency. |
