| 摘 要： | 采用丰富度指数、Shannon-weiner指数、Simpson指数、Pielou均匀度指数、Alatalo均匀度指数5种多样性测度指标,对沧州沿海区、过渡区和内陆区的林木种质资源进行了多样性比较分析,结果表明:Shannon-weiner指数和Simpson指数在3个区域的变化趋势大致相同,均表现为内陆区经济林最大,沿海区用材林最大,而用材林+经济林二指数较为接近.过渡区物种丰富度最高,其次为内陆区和沿海区.沧州市林木资源总体的均匀度偏低(均匀度指数<0.6),仅杨、柳、榆、白蜡、枣等几种乡土树种就占到全部林木资源的90%以上. |

| Abstract: | Five diversity indexes,including richness index,Shannon-Weiner index,Simpson index,Pielou evenness index,and Alatalo evenness index,were used to analyze diversity of forest resources in littoral zone,transition zone,and hinterland zone in Cangzhou City,Hebei Province. Results showed that the changing tendencies of Shannon-Weiner index and Simpson index were approximately similar in the littoral zone,transition zone,and hinterland zone. The economic forest in the hinterland zone and the timber forest in the ... |
