| 摘 要： | 针对黄土高原退耕区域不同植被恢复类型中植被群落特征及多样性的问题,以农地(F)为对照,对天然侧柏(B)次生林、不同林龄(5、20 a)刺槐人工林(C5,C20)、荆条灌丛(H5)和苜蓿草地(M)6种不同植被恢复类型群落特征及物种多样性变化研究。结果表明,通过植被恢复,物种丰富度均比农地增加,乔木>灌木>草本;群落丰富度指数撂荒地最高,农地最低,顺序为:H5>C20>C5>B>J>M>F;Simpon优势度指数,B>C5>C20>J>M>H5>F。Shannon-Wiener多样性指数:C20>C5>B>H5>J>M>F;Sheldon均匀度指数:B>C20>C5>J>M>F>H5。通过植被恢复,物种数量提高,群落多样性改善,有利于植被生态效应的建设。

| Abstract: | Taking farmland(F) as the control,the species diversity of vegetation population and community of six vegetation restoration types were studied,such as Platycladus orientalis(B),20-year Robinia pseudoacacia(C-20),5-year R.pseudoacacia(C-5),5-year abandoned land(H-5),and Medicago sativa(M).The results showed that species richness increased after vegetation restoration and with the order of tree > bush > grass;the sequence of the index of community richness was H-5>C-20>C-5>B>J>M>F;the final sequence of Simpo... |
