青藏铁路沿线植物群落β多样性研究
β-diversity of Plant Communities along the Line of Qinghai-Tibetan Railway
摘要
Abstract
[Objective] The aim was to analyze β-diversity of plant communities along the line of Qinghai-Tibetan railway and understand change pattern of plant communities along the line of Qinghai-Tibetan railway.[Method] The plant communities diversity along the line of Qinghai-Tibetan railway had been quantitatively analyzed by using β-diversity index formulas.[Result] Theβ3w index of all transect was descend along the railway.The max.was 4.135 at 9 transect and the min.was 1.000 at 24 transect.The βC index and βT index between the 1 transect and other transects had the same diversification trend.The max.of βC and βT was 44.500 and 4.188 between 1 and 12 transect and between 1 and 9 transect.The min.was 7.000 and 1.100 between 1 and 2 transect and between 1 and 24 transect.The value of βCJ and βCS was 0.875,0.978,0.984 as well as 0.778,0.935,0.968 between 1 and 2,5,17 transects,and the other values of βCJ andβCS was 1.000.TheβC andβT index at any every two transects had similar diversification trend.The max.ofβC andβT was 43.000 and 3.542 between 24 and 25 transect and between 2 and 3 transect.The min.was 7.000 and 0.678 between 1 and 2 transect and between 20 and 21 transect.The max.of βCJ andβCS was 1.000 all between 2 and 3 transect.The min.was 0.440 and 0.333 all between 20 and 21 transect.[Conclusion] The results provide theoretical basis for vegetation management and biodiversity conservation of Qinghai-Tibetan railway.关键词
