新疆天山西部树皮生地衣群落最小面积的初步研究

摘要

我们采用Sorensen和Kulcinsky平均相似系数研究了分布在天山西部山脉的树皮生地衣群落的最小面积.结果表明，树皮生地衣群落的定性和定量最小面积分别为25～50cm2和51～72cm2，同时证明了整体取样技术适合树皮生地衣的植物群落学研究.%The minimal area of a corticolous lichens community in Western Tianshan was studied by using the method of mean similarity coefficients of Sorensen and Kulcinsky. The determination of the qualitative and quantitative minimal areas,which are 25～50 cm2 and 51～72cm2,respectively,allows the phytosociological study of the corticolous communities of Western Tianshan by means of integral sampling.
