中文摘要：
应用除趋势对应分析（DCA）与双项轨迹方差法（TTLQV）相结合的方法，对云顶山亚高山革甸群落格局进行分析。结果表明．在亚高山草甸群落格局分析中，这2种方法的结合可以成功地揭示群落的特征。披针苔草＋车前群系、披针苔草＋蒲公英群系和嵩草＋车前群系的格局差异明显．随着海拔的升高，草甸群落的格局规模增大，群落分布格局不仅受优势种的生物学特性影响．还受环境因子制约．结果很好的揭示了云顶山亚高山草甸群落的结构特征。
英文摘要：
The detrended correspondence analysis （DCA） ordination technique combining two-term local quadrat variance （TTLQV） method was used for community pattern analysis of a subalpine meadow community on Yunding Mountain, Shanxi. The results showed that the combined application of these two methods can successfully reveal community structure in the pattern analysis Of a subalpine meadow community. The patterns of form. Carex lanceolata ＋ Plantago asiaticadepressa, form Carex lanceolata ＋ Taraxacurn rnongolicurn, and form Kobresia bellardii ＋Plantago asiaticadepressa were significantly different from each other. The scale of the pattern gradually increased with increased elevation. The community pattern of subalpine meadow was not only related to the biological characteristics of dominant species, but was also affected by environmental factors. The results also successfully reveal the characteristics of community structure of subalpine meadow on Yunding Mountain.
