河南洛阳城市寺庙园林植物群落特征

A Study of Luoyang City Plant Community Characters of Temple Gardens in Henan

以洛阳市城区范围内的5个佛寺庭院和2个祠庙庭院作为调查研究对象,运用植物群落学的方法,对各寺庙植物种群多样性、物种丰富度及群落相似性系数进行比较分析。结果表明:17个寺庙植物群落共有维管植物73种(包括变种),隶属49属33科,优势植物群落为乔木,其中常绿乔木占主导地位[1]。2各寺庙内寺庭与寺园乔灌木层均匀度指数值都比较高,说明寺庙内各树种分布数量比较均衡;各寺园物种丰富度及多样性指数均大于寺庭,说明寺园区域多为寺庙公共绿地。3各寺庙间相似性系数值较小,证明所调查的7个寺庙间植物种类重复概率比较低,各寺庙园林植物配置差异较大。

This paper takes the five Buddhist temple courtyards and the two Ancestral temple courtyards in Luoyang City as studying objects ,employing the method of phytocoenology to compare and analyze the population diversity, species richnessand community similarity of plants. The results are as follows：（1）there are 73 kinds of tracheophytes including their varieties,which are divided into 49 genera and 33 families. Arbor is the major plant community, among which evergreen trees take a leading position;（2）the average degree of evenness of shrub layer is relatively high in temple, thus the balance of species distribution in temple gardens is indicated. The plant species richness and diversity index were larger in temple garden ,The temple garden area is more public green space for the temple. （3）the similarity coefficient of each temple is low, thus indicating that there are relatively low of the plant species repetition rate in the seven temples, a large number of plant species and a low repeatability in temples.
