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。
採用灰色關聯法，對冀北山區華北落葉鬆人工林與油鬆天然次生林群落穩定性進行研究。結果錶明：同一海拔樣地比較，落葉鬆林土壤肥力高于油鬆林；除坡頂樣地外，落葉鬆林同海拔樣地內植被生長狀況優于油鬆林；除坡中樣地外，油鬆林同海拔樣地內林下草本物種多樣性優于落葉鬆林；除坡頂樣地外，落葉鬆林綜閤穩定性評價優于油鬆林。

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 .
