摘要/Abstract

摘要：

研究了贵阳市花溪区大学城附近植物群落在火烧、道路、弃耕和砂石堆放等4种人为干扰类型对植物多样性的影响。结果表明:物种丰富度指数和多样性指数均以弃耕地最高,其次为火烧迹地和道路干扰样地,砂石堆放地物种丰富度和多样性指数最低;均匀度指数以砂石堆放地最低,其余3种干扰类型样地差别不大。弃耕地与火烧迹地的相似性指数最高,而弃耕地与砂石堆放地的相似性指数最低;经过与土壤水分含量进行相关分析,丰富度和均匀度指数与土壤水分呈显著正相关,多样性指数和生态优势度指数与土壤水分相关性不显著。

关键词: 人为干扰, 植物多样性, 土壤水分, 贵阳市

Abstract:

Characteristics of plant diversity of urban suburbs where such disturbances by human activities take place as farmland interference,road interference,engineering waste interference and fire interference were studied.The results showed that the species richness index and species diversity index of abandoned farmland were the highest,the second were road interference and fire interference types and the engineering waste interference was the lowest.Evenness index of engineering waste interference was the lowest and the three other types were not different obviously.The similarity indexes of abandoned farmland interference types and burned area interference type were the highest,but the similarity indexes of abandoned land and engineering waste interference land were the lowest.Correlation analysis with soil moisture content showed that soil moisture was positively correlated with richness index and evenness index,but not significantly correlated with diversity index and ecological dominance index.

Key words: human interference, plant diversity, soil moisture, Guiyang
