| 摘 要： | 应用物种多样性Shannon-wiener指数(Hsw)、Simpson指数(Hsim)、Pielou均匀性指数(Jsw和Jsim)以及生态优势度(C)指标对甘肃省白水江自然保护区持续林业示范区次生灌木林物种多样性进行了测算。结果表明,该区物种多样性指数分别是:Hsw=l.7319-2.9314;Hsim=0.7550-0.9343;Jsw=0.6720-0.9050:Jsim=0.8199-0.9732。表明该区群落组成成分复杂、种类丰富。生态优势度指数低(0.0657-0.2450),人为活动影响强烈,最后阐述了生物多样性的保护策略及与社会经济系统的相互作用关系。

| Abstract: | The species diversity of secondary shrub forest is estimated by applying Shannon-wiener index, Simpson index, Pielou index (evenness) and ecological dominance in Gansu Baishuijiang natural reserve. The results show that the species diversity indexes are as follows: Hsw=l.7319-2.9314, Hsim=0.7550-9343, Jsw=0.6720-0.9050, Jsim=0.8199-0.9732 respectively. According to the above measured values, this community consists of abundant and complex species. The ecological dominance index is lower because of the stronger influences of mankind. This paper lastly sets forth the tacties of biological diversity protection and its relation to the social ecoromic system. |
