| 摘 要： | 依据2020年在澜沧江流域分层抽样调查的120个云南松样地数据，提取云南松群落数据和地形因子数据，采用典型对应分析法研究澜沧江流域云南松群落的分布与海拔、坡向和坡度的相关关系。结果表明，地形因子中对澜沧江流域云南松群落分布影响较大的因子为海拔，其次为坡度，坡向对云南松林分布的影响较小。

Relationship between Pinus yunnanensis Communnity Distribution and Topographic Factors in Lancang River Basin |
| |
| Abstract: | Based on the data of 120 Pinus yunnanensis sample plots in Lancang River Basin in 2020, this paper extracted the data of Pinus yunnanensis community and topographic factors to study the relationships between the distribution of Pinus yunnanensis community and elevation, aspect, and slope by canonical correspondence analysis (CCA) in Lancang River Basin. The results showed that elevation was the most important topographical factor affecting the distribution of Pinus yunnanensis community in Lancang River Basin, followed by slope, while aspect had little influence on the distribution of Pinus yunnanensis community. |
