摘要:
依据宝天曼栎类天然次生林32块样地的调查资料,建立栎类天然次生林群落稳定性综合评价指标体系,定义了稳定度指数计算公式及评价方法,运用EXCEL和SPSS统计软件进行数据处理。结果表明,该地区栎类天然次生林群落稳定性因乔木的树种组成而异,锐齿栎+短柄木包树群落结构最优;125 0 m以上随海拔的升高其稳定性呈增强趋势;样地分布显示,该群落稳定性较强与较差2类几乎各占1/2,因此宝天曼栎类天然次生林群落的稳定性应成为值得关注的重要问题。西北林学院学报21卷第5期闫东锋等宝天曼栎类天然次生林群落稳定性研究
Abstract:
Based on the data collected from 32 samples plots of natural secondary oak forests in Baotianman Nature Reserve,the system of comprehensive assessment indexes of community stabity of natural secondary oak forests was established,the computation formula and assessment method of stability degree indexes were defined,and statistic sofwares of EXCEL and SPSS were adopted to process data.The results indicated that the community stabilityies of natural oak secondary forest varied with the composition of tree species,The community with the tree species of Quercus acutidentata + Q.glanduifera var.breripetiolata was the most stable one.On vertical gradient,community stabitity increased along with the increase of altitude above 1 250 m.The distribution of the sample plots showed that those with relatively good and bad community stability almost went halves,indicating the severity of the community stability in this region.
