摘　　要：根据植物区系分区的原则和方法,将崂山地区划分为五个植物小区,分别为北九水植物小区(A小区)、仰口植物小区(B小区)、北九水到太清宫过渡的植物小区(C小区)、太清宫植物小区(D小区)、华楼和夏庄植物小区(E小区)。在此基础上,绘制崂山植物区系分区图,探讨各个植物小区的种的丰富度、相似性系数和特有性等区系特征。结果表明:A小区的植物种类最丰富,植物种类数占总种数的70.4%,E小区最贫乏(22.1%);A小区和C小区两个植物小区的物种相似性系数最高(53.3%),D小区和E小区的相似性系数最低(30.8%);特有种在各小区所占比例中B小区比例最高(17.29%),E小区比例最小(7.21%)。According to the principles and ways of the floritic division,the scheme of the floritic division of Mt.Laoshan was put forward.And then,the map of the floritic division of Mt.Laoshan was drawn.Finally,the flora features of each minor plant district including species abundance,conformity coefficient of species and the endemic species were discussed.As a result,number of species distributed in A minor plant district was the most abundance（70.4%）,number of species distributed in E minor plant district was the least（22.1%）.The conformity coefficient of species between A and C minor plant districts was the highest（53.3%）;however,the conformity coefficient between D and E minor plant districts was the lowest（30.8%）.The percentage of endemic species distributed in B minor plant district was the most;the percentage in E minor plant district was reverse.
