| 摘 要： | 对长白山内2条相邻道路周围的植物和土壤进行了调查分析,在道路两侧设置垂直于道路的样地,分别计算距离道路不同距离样带内草本植物Shannon-Wiener多样性指数,Pielou均匀度指数。结果表明:在距道边5 m的影响范围内,植被表现出一定的边缘正效应;并对样带内土壤进行理化性质分析,铅含量与有机质呈显著正相关,与土壤pH呈显著负相关;边缘土壤氮含量和pH值较高,反应了道路对植被—土壤系统的影响因素主要来自汽车尾气,以及道路修建;同时也受到道路修筑时材料堆积和人为践踏等对原有植被及其基质破坏产生的影响,道路使用年限也对两侧植物以及土壤造成一定影响。

| Abstract: | In this paper,for the roads around plants and soil were investigated and analyzed within two adjacent roads around the Changbai mountains,set plots which perpendicular to the road on both sides,and calculate Shannon-Wiener diversity index,Pielou evenness index within the herb transect at different distances from the road.The results showed that within the 5 m affected areas from the road side,vegetation shows positive edge effects.And analysis of soil chemical properties,lead content and organic matter were... |
