摘要

采用均匀分布和典型样地相结合的方法

对徐州地区4条省道绿化状况进行了调查

并利用重要值、丰富度指数、Shannon—Weiner多样性指数、Pielou均匀度指数、相似性指数分析其植物组成及多样性。结果表明:(1)4条省道共有乔木31种

灌木17种

草本40种。杨树、女贞、龙柏、三叶草在徐州地区主要省道绿化中发挥着重要作用

其重要值和出现频率均排在前列。(2)省道S323乔灌种类最多

省道S253草本最多

人工绿化的乔、灌在一定程度上抑制了杂草生长。植物群落综合Shannon—Weiner指数排序为S323>S322>S253>S251。每条省道的丰富度指数、Shannon—Weiner指数和Pielou指数均为草本>乔木>灌木。(3)两两省道之间的相似性指数均为30%～50%

草本植物的共有种对相似性指数贡献最大。在进行道路绿化的过程中

需要乔灌草统一考虑

特别是增加草本植物的多样性以抑制杂草生长。

Abstract

According to plants investigation with the combined method of uniform distribution with typical sampling area

the plant species and diversity along four provincial roads in Xuzhou area were studied by using significant value

richness index

Shannon-Wiener index

Pielou evenness index and similarity index.Results showed that(1)there were 31kinds of arbor

17kinds of shrub and 40kinds of herbage along the four roads.Populus

Ligustrum lucidum

Juniperus chinensis cv.kaizuk and Trifolium played important roles

and their significant value and frequency of occurrence were at the top.(2)The species of arbor and shrub occurred mostly in S323and the species of herbage

mostly in S253.Artificial trees and shrubs inhibited the growth of weeds to some extent.Comprehensive Shannon-Wiener index was in the order of S323>S322>S253>S251.Richness index

Shannon-Wiener index and Pielou evenness index were all in the order of herbage>arbor>shrub along every provincial road.(3)The similarity index was between 30%and50% and herbage species had the greatest contribution to it.During road greening

we need consider the community as a whole

especially increase the diversity of herb to inhibit weed growth.
