| 摘 要： | 长白山森林是水源用材林,森林覆被率65.2%。森林龄组结构不合理,表现在成过熟林多,更新的幼令林少。一、原始林的采伐更新,应考虑更新树种,森林环境条件,进行生态摸拟。应用生态型的采伐更新方式进行。更新树种为耐阴的云杉、冷杉、红松等树种时,采用择伐方式。更新树种为喜光的落叶松或杨树等阔叶树种时,可采用1—2ha内的小面积皆伐,保证上方光照,以利更新。二、次生林采伐更新方式,可结合改造进行,以窄带皆伐(10—15m宽)或团状择伐为主,及时更新。

| Abstract: | Forest in Changbai Mountain is a source of water and timber. The forest-covering rate is 65.2 percent.The structure of age-class distribution isn't right because of many overmature forest and little young age forest. Preliminary forest cutting and regeenration, we must consider the reproduction trees, forest enviroment, ecological analogy. The second forest cutting and reproduction.mainly adapt clear-strip cutting(10-15m)or round selection cutting |
