色季拉山急尖长苞冷杉林下苔藓植物多样性研究
|
摘要
对色季拉山(定位站附近)急尖长苞冷杉林下苔藓植物进行了调查,从种类组成、相似性、α多样性等方面进行了分析。结果表明:色季拉山急尖长苞冷杉林下苔藓植物共10科16属20种(含1亚种),其中塔藓科属数最多,为3个;科内种数超过3种的共有4个优势科,分别为曲尾藓科、塔藓科、真藓科、丛藓科;属内种数大于3种的优势属仅丝瓜藓属1个。苔藓植物水生种类极少,仅1种,土生、岩石(岩石薄土)、腐木种类为该研究区域苔藓植物分布的广泛类型。5个样地共有种类数量变化不大,导致种相似性系数也很接近。通过Shannon指数、Simpson指数、Pielous指数的计算,各指数所反映的苔藓植物多样性情况基本是一致的,此研究区域苔藓植物丰富度高,均匀度也比较高。
By means of species composition,similarity coefficient and diversity index,the characteristics of diversity bryophyte in Sejila Mountain were studied.The resuLts showed that there were 20 species(including one infraspecies taxa)belonging to 16 genera of 10 families;the maximum number of genera was Hylocomiaceae including three species;there were a total of 4 dominant families with more than 3 species in the family, namely Dicranaceae, Hyocomiaceae, Bryaceae and Pottiaceae; there was only one genera with more than three species, namely Pohlia.The total number of species in the 5 plots changed a little,which led to the similarity coefficient being close to each other.Through the calcuLation of Shannon index,Simpson index and Pielous index, the each index reflected that the diversity of bryophytes was basically consistented.The bryophyte richness and uniformity were high in this area.
