1. The results show that : in the 2 - 4m of road buffer zones and 0 - 10m of infrastrctuer buffer zones , the density of dominant species and biomass will decrease for herbs , and abundance and proportion will get bigger than other exents ( inner species increasing owing to the outer species invading ) ; in the shrub disturbence extent , there exists an inverse relationship between the influence degrees and buffer zones ; in the 40m of infrastructure buffer zones , there has the biggest influence on the trees , however , the effect of road buffer zones is unobvious , only a small change on the morphology
   结果表明，草本类，游道影响源干扰区在2 4m ，设施类在0 10m ，原有优势种密度减小，物种丰度较其它干扰范围内有所增加(外部种入侵导致本地植物的种类数目增多) ，均匀度也增大，生物量减少；灌木类，在干扰范围内，影响程度与影响源的距离成负相关关系；乔木类，接近设施类40m处影响最大，游道类影响源则影响效果不明显，只有形态上略有变化。
