| 摘 要： | 在辽宁章古台地区风蚀荒漠化地设置固定标准地和临时标准地,对平均树高和平均胸径的生长状况进行多重比较,樟子松在纯林和混交林中生长差异显著,混交林中生长状况好于纯林,树高、胸径生长状况最好的分别为樟子松 皂角和樟子松 胡枝子混交林。对年龄相近的樟子松纯林和樟子松杨树混交林单位面积林木生物量分析,混交林中林木生物量高于纯林。研究表明,实现沙区樟子松可持续利用的有效途径是选择适宜树种,营造混交林。

| Abstract: | Growth status of Pinus sylvestris var.mongolica was studied by setting fixed and temporary sample plots and conduting multiple comparisons among average height and DBH of the trees.The growth difference is remarkable and better one is in the mixture forests.The better ones are Pinus Gleditsia and Pinus Lespedeza.Biomass of unit area in the same ages in mixed forests is better than in pure ones.The conclusion shows that choosing suitable mixed forest type for deserts is the effective way to realize sustainable use of P.sylvestris var.monglicas in desert region. |
