摘要：

采用样方调查方法,对云南轿子山自然保护区高山柏群落植物多样性进行研究。研究结果表明,保护区内高山柏群落均分布在海拔3000m以上的多风、多岩石的向阳坡,以禄劝县境内的雪山乡最为集中。在山体上段(高于3500m)主要形成灌丛,而于山体下段(低于3500m)则形成森林;群落内层次结构和物种组成都较简单,高山柏群落内的种子植物在属级水平上以北温带分布类型及其变型最多,占总属数的53.25%;在种级水平上以轿子山-西南共有变型最多,占总种数的31.86%;物种丰富度、Simpson指数和Shannon-Wiener指数均是群落>草本层>灌木层>乔木层,而Pielou均匀度指数是草本层>群落>灌木层>乔木层,三个层次中各指数皆以草本层为最高。

摘要：

by use of the quadrat sampling method,the plant diversity of the Sabina communities in Jiaozishan Nature Reserve was studied. The results showed that the Sabina communities were located in the sunny and rocky places above 3000 m,especially in Xueshan town of Luquan County. It was mainly in form of shrub in the upper section of the mountain( above 3500m),and became forest in the lower sections( less than 3500m); the community layer structure and the species composition were relatively simple; at the genus level,seed plants of the community were mainly north temperate elements,accounting for 53. 25% of the total number of genera,while at the species level,the seed plants were mainly the Jiaozishan- Southwest variants,accounting for 31. 86% of the total number of species. Species richness,Simpson index and Shannon- Wiener index were all in the order of community > herb layer > shrub layer > tree layer,and Pielou index was in the order of herb layer > community > shrub layer > tree layer. Every index was the highest in the herb layer.
