摘要
对韶山景观竹林进行林相整理、疏伐抚育并施以氮、磷、钾和复合肥处理,处理20个月后对植物群落多样性进行了调查。结果表明:人工施抚育明显改变了林内的层次结构和盖度,灌木和草本层部分种类增加,对照与处理在总数上差异达显著水平;施肥处理后,样地中草本层和整个群落的多样性指数明显增加,与对照相比均达到显著水平;处理后草本层和整个群落的相似系数与对照的差异达显著水平。
The landscape forests of Phyllostachys heterocycla cv.pubescens in shaofeng were fertilized with nitrogenous,kalium,phosphor and compound fertilizer.The plant community biodiversity in the forests were investigated after treated for 20 months.The results show that the fertilizers obviously changed the forest＇s plant hiberarchy and cover percent,the plant species in the shrub and herb layers increased,and compared the two layers with the control, the differences reached a remakable level on the whole;the plant diversity in the whole community and in the herb layer increased notablely,and compared them to the control,the differences in the aspects of targets reached a significant level;compared the treated herb layer（with P,N and compound fertilizer）and whole community to the control,the differences in the aspect of similarity coefficients reached a remarkable level.
