基于七溪岭自然保护区穗花杉群落生态系统的调查,发现穗花杉群落的主要伴生树种为壳斗科、樟科树种;应用物种丰富度指数、多样性指数、均匀度等指标测定珍稀濒危植物穗花杉群落在不同海拔梯度的物种多样性,分析发现穗花杉群落分布的特定性和物种多样性的梯度变化规律,受海拔和坡位影响明显。
Based on the investigation of the Eupatorium chinensis community ecosystem in Qixiling Nature Reserve, the main associated species of Pinus koraiensis were Pinaceae and Lauraceae species. The species richness index, diversity index and evenness index were used to determine the species diversity of rare and endangered plants The species diversity of Pinus massoniana at different altitudes shows that the distribution of Pinus massoniana and the gradient of species diversity are affected by the altitude and slope position obviously.
