摘要: 采用灰色关联法,对冀北山区华北落叶松人工林与油松天然次生林群落稳定性进行研究。结果表明:同一海拔样地比较,落叶松林土壤肥力高于油松林;除坡顶样地外,落叶松林同海拔样地内植被生长状况优于油松林;除坡中样地外,油松林同海拔样地内林下草本物种多样性优于落叶松林;除坡顶样地外,落叶松林综合稳定性评价优于油松林。
英文摘要: By using the grey correlation method , the community stability of plantation of Larix principis-rupprechtii and the natural secondary forest of Pinus tabulaeformis in the mountain areas of northern Hebei was studied .The results show that at the same altitude plots ,the soil fertility of larch forest is higher than that of Pinus tabulae f ormis .In addition to the top plots of the hill ,the vegetation grow th status of larch forest is superior to that of the Pinus tabulae f ormis at the same altitude .In addition to the middle plots of the hill ,the herbaceous species diversity of Pinus tabulae f ormis is higher than that of larch forest at the same altitude .In addition to the top plots of the hill ,the larch forest stability is better than that of Pinus tabulae f ormis .
