| 摘 要： | 在１￣７月对紫金山紫薇－山胡椒群落（Ｆｏｒｍ．Ｌａｇｅｒｓｔｒｏｅｍｉｓ ｉｎｄｉｃａ－Ｌｉｎｄｅｒａ ｇｌａｕｃａ）的早春草本层进行了定位连续的群落学调查统计。结果表明,生于落叶林下的含明党参（Ｃｈａｎｇｉｕｍ ｓｍｙｒｎｉｏｉｄｅｓ ｓｍｙｒｎｉｏｉｄｓ Ｗｏｌｆｆ．）早春草本层植物通常２月萌芽,在早春落叶乔木尚未展叶林内透光好的条件下旺盛生长,在６月初落叶乔木展叶郁闭度增高后完成生活史。早春

| Abstract: | According to the continuous observation to two perminent plots in Purple Mountain, Nanjing, the characteristics of community in which early\|spring herbs stratum including \%Changium smyrnioides \%Wolff. was located were studied. The early\|spring herbs usually accomplish their life cycle during January to June in the year accompanying with the change of deciduous arborous canopy density, it showed a harmonous phenological appearance among them. The Shannon\|wiener diversity index and Simpson diversity index of this herb stratum are 1.429, 0.699 (plot 1) and 2.059, 0.852 (plot 2) respectively. The aggregate distribution pattern of \%C. smyrnioides \%population may reflect its reduced feature. |
