摘要
对水胡黄天然次生林的植物物种组成及多样性进行分析的结果表明:两个地点所有物种的共有度为0.681;通过调查,标准地中共记录植物物种60种,分别隶属于39科、54属,其中乔木16种、灌木14种(藤本2种)、草本30种;茂林河林场木本植物的物种多样性明显高于建设营林所,其丰富度指数为30,Shannon-Weiner指数达到2.602,均匀度指数为0.914,优势度指数为0.116;而且两个地点的乔木层的多样性指数明显高于灌木层的多样性指数。
Plant species composition and diversity of Shuihuhuang natural secondary forests were studied in this paper. The results showed that total degree of all species at two locations was 0. 681. A Total of 60 plant species from 54 genera in 39 families were found in all standard ground, among which, 16 arbor specieses, 14 shrub specieses （2 liana speeieses） and 30 herb specieses. The species diversity of woody plants in Maolin River Forest was significantly higher than Jianshe forest, its richness index was 30, Shannon - Weiner index was 2. 602, evenness index was 0. 914, dominance index was 0. 116. And the two locations of the diversity index of tree layer were significantly higher than the diversity index of shrub layer.
