南京地区寺庙园林植物群落特征研究

选择了南京地区的10个寺庭和10个寺园作为调查研究对象，运用植物群落学的方法，共记录维管植物146种（含变种），隶属于96属．63科。对各植物群落优势种群、物种丰富度、物种多样性及群落相似性进行了分析，结果表明：①寺庭和寺园的优势树种均为乔木。乔木在整个植物群落中占主导地位；灌木层（0．32株／m^2）的总体密度大于乔木层（0．21株／m^2）。寺园的乔木密度（2．4株／m^2）和灌木密度（4．5株／m^2）均大于寺庭。②寺园样地物种丰富度和Simpson指数均高于寺庭样地，反映了寺园样地为寺庙附属绿地，物种丰富度较高，群落层次与结构较合理；乔木层和灌木层的Pielou指数均较高，说明寺庙园林中各树种的数量分布均匀。③各寺园的相似性系数相对高于寺庭，但均未超过50％，反应了寺园中物种的种类相对丰富度较高，相对于树种较少的寺庭，树种重复出现几率明显提高。

Study on Plant Community Feature in Nanjing Temple Garden

10 temple courtyards and 10 temple gardens were chose as the researching object in the Nanjing temples. There were 146 species of vascular (including varieties),which belong to 96 genera and 63 families. The richness index, simpson index, species diversity and similarity index of gardening plant community were analyzed. The results showed: ①The dominant species of temple courtyards and temple gardens were all trees;The density of shrub layer (0.32 strains/m~2) was greater than the tree layer (0.21strains/m~2).②Both of the simpson index and the Species diversity in temple garden plots were higher than the temple courtyard plots;The pielou index were on a higher level both in the tree layer and the shrub layer,which indicated that quantities of each tree species were on a average level.③The similarity index in temple gardens was higher than the temple courtyards, both less than 50%,which indicated that the repetitong rate of each tree species was obvious greater in the temple gardens than in the temple courtyards.
