摘要
用种毗连法和种小区法对五台山２４００２８００ｍ的亚高山草甸的小格局分析．结果表明：在小格局中，大部分种与优势种苔草呈正关联；小格局规模都较小，各个种趋于交错分布；不同规模的格局应用不同的分析方法，小格局不能用中格局分析方法进行研究；种小区法和种毗连法都是有效的小格局分析方法，从本文结果看前者优于后者．
The species juxtaposition and species region methods were used in the anslyses of small scale pattern in subalpine meadow on the Wutai Mountains at 2400～2800 m. The interspecific relations, pattern scales and some ecological relationships in the meadow were clearly illustrated by the analyses. In the small scale pattern of the subalpine meadow, most species were positively correlated with dominant species, Carex sp.; scales in small scale pattern were small and species tended to be inter distributed with their leaves, stems and tillers; different pattern scales should be analysed by different pattern analysis methods. The two techniques used here are suitable for small scale pattern study. Comparitively, the result from species region is better than that from species juxtaposition.
