Study on the Structure of the Subalpine Meadow Community of Wuling Mountain
摘要/Abstract
通过对雾灵山亚高山草甸植物群落基本特征的研究, 发现在调查所涉及的52种植物中, 大叶章、硬质早熟禾、地榆、藁本、双花堇菜、细叶藁本、银莲花、披针叶苔草以及细叶苔草等植物的重要值较高, 在群落中占据明显优势 .群落的 Simpson指数为11.75;Shannon-wiener指数为 4.19;PIE指数为0.91.以这 3个指数为基础的群落均匀度指数分别为0.17,0.69,0.93.从总体来看, 群落的生态优势度指标偏高, 而物种多样性指数偏低 .瑙基耶尔生活型谱分析得到以下结果 :高位芽和地上芽植物各1种, 分别占总种数的 1.9% ;地面芽植物和隐芽植物占绝对多数, 分别为 31种和 16种, 占总数的 59.62 %和 30.77%;1a生植物有3种, 占5.77% .表明该地区为夏季较短, 冬季漫长, 气候严寒而潮湿的温带气候特征
It shows that the species of Calamagrost is purpurea, Poa sphondylodes,Carex lanceolata, Sanguisorba of f icinalis, Anemone cathayensis,Ligusticum sinense ,Viola bif lora ,Carex rigescens a ndLigusticum tenuissimum hav e g reater impo rtance v alue than the others of the 52 species thro ugh thestudy on the basic characters of the subalpine meadow community of Wuling mountain. The Simpsonindex of the communi ty is 11. 75, Shannon-wiener index i s 4. 19, and the PIE index i s 0. 91, as w el l asthe species ev enness index es which based o n the three fo renamed index es are 0. 17, 0. 69, 0. 93 separately. It comes to the conclusio n tha t the ecological dominance of the communi ty i s a li tt le hig her a ndthe species div ersi ty i s less than norma l. The life-fo rm spectrum analy si s show s tha t hemicrypto phy tepredominates absolutely in the community w hich processes 31 species. Crypto phy te, which processes16 species, i s secondly to hemicry ptophy te. Thero phy te is less, there are 3 species belong to i t. Phaenerophyteand chamaephy te are the least, they hav e only 1 species separat ly. The ratio of them in thecommuni ty are 59. 62% , 30. 77% , 5. 77% , 1. 92% a nd 1. 92% independently. This kind of life-formspect rum reflected the special envi ro nment and the local climate. And the result i s consistent wi th theconclusio n o f Raunkiaer.
