摘要： 在分析植物群落和生态因子数据的基础上,利用PCA排序、相关和回归分析等多元分析技术,描述了大兴沙地草本植被的空间分布与主要生态因子的相关性,数量地表达了植被分布与环境的关系。结果表明:土壤中小于0.001mm颗粒含量和土壤全P含量是影响植被分布的主导生态因子。
关键词: 大兴沙地, 植被分析, 生态因子, 多元分析
Abstract: Based on the analysis of plant communities and ecological factor data,by the correlation analysis and regression analysis,the relations between the spatial distribution of herbaceous vegetation in sandy land in Daxing and ecological factors were discussed and expressed quantitatively in the paper.The result shows that the < 0.001 mm grain content and the total phosphorus content in soil are key factors which strongly affect the vegetation distribution.
Key words: Daxing sandy land, Vegetation analysis, Ecological factors, Multivariate analysis
