摘要：调查了海拉尔市巴音岱林场不同分布格局、不同带间距的人工樟子松林带内植被恢复过程及物种多样性的差异,分析了林草界面生态学效应,研究了林草界面对带间植被自然恢复的作用。结果表明,宽的带间距带内物种多样性和生物量变化曲线出现了两个高峰,而窄的带间距带内只有一个高峰,说明该地区林带之间距离不应小于12 m;当林带之间距离为16～28 m时草本物种多样性出现最大值。植被恢复效果表现为带间距12 m差于带间距24 m,虽然都差于天然植被,但边际效应大大地加速了群落演替的进程。研究区樟子松林草界面边缘效应影响域为20 m,其小尺度范围内生境异质性也很明显。行带式造林带间距离不应大于40 m,超出边缘效应影响域不利于带间植被恢复。
A survey of vegetation diversity and recovery process in different Mongolian pine fixing sand belts was conducted in Baiyindai forestry centre,Hulunbuir City,Inner Mongolia,China.Its goal is to disclose the boundary ecological effect of forest and grassland,and clarify the effect of landscape boundary on vegetation restoration.The results show that there are two peaks of species richness and biomass change when the distance between neighboring forest belts was 24 meters;while there is only one peak when the distance between the belts is only 12 meters.Accordingly,the distance between belts should be no less than 12 meters.Herbage species richness and biomass will come into the maximum value when the distance between the belts vary from 16 meters to 28 meters.The vegetation restoration in the 12-m interval belt is poorer than that in the 24-m interval belt,and the vegetation restoration in the 24-m interval belt is poorer than that in natural vegetation.It show that the boundary effect accelerates the process of community succession.The boundary effect area of the pine forest belts is no more than 20 meters,and habitat heterogeneity is very obvious in the small scale.The duration of forest belt should not be more than 40 meters,otherwise the vegetation will be hard recovered because of not within the boundary effect area.
