| 摘 要： | 在大量调查研究的基础上，得出了影响侵蚀沟内油松天然更新的因子有：沟坡方向，侵蚀沟部位（纵向位置），侵蚀沟深度和地被物厚度，对侵蚀沟内外油松的生长对比以及侵蚀沟内油松更新幼树连续5年生长量的调查研究表明；侵蚀沟内油松天然更新幼树连年生长量很大，侵蚀沟内外油松径生长量相当，树高生长量却相差悬殊，沟内油松树高是沟外油松树高的2倍。

| Abstract: | The paper concluded that the factors of affecting the regeneration of Chinese pine are the direction of gully?the position in gully?the deeper of gully and the deeper of ground cover according to lots of researches.The comparison between growth of Chinese pine in and out of gully and the growth of Chinese pine in gully in recent 5 years indicated that the growth of regeneration sapling of Chinese pine in gully is very large,the diameter of Chinese pine in and out of gully is about the same, but the height is very different.The height of Chinese pine in gully is double as that out of gully. |
