新疆天山西部岩面生地衣群落最小面积的初步研究

Primary Study the Minimal Area of Saxicolous Lichen Community of Western Tianshan

我们采用Srensen和Kulcinsky平均相似性系数 ,研究了分布在天山西部山脉的岩面生地衣群落的最小面积。结果表明 ,岩面生地衣群落的定性和定量最小面积分别为 30～ 6 0cm2 和 40～ 70cm2 ,同时证明了整体取样技术适合岩面生地衣的植物群落学研究。

The minimal area of a saxicolous lichen community of western Tianshan in Xinjiang was studied by the methode of the mesn similarity coefficients of Sorensen and Kulcinsky. The determination of the qualitative and quantitative minimal areas which are 30～60cm and 45～70cm, respectively allows the phytosociolgical study of the saxicolous community of western Tianshan by the method of integral sampling.
