山西外引园林树种限制性生态因子关联度分析

Limiting Ecological Factor Correlation Analysis of Shanxi Exotic Tree Species

摘要: 采用实地调查法对山西外引园林树种的生物学特性、生态学习性以及当地的主要生态因子等进行了系统调查。依据主导因子引种理论，分析了不同生态因子在引进植物适应性栽培过程中所发挥的作用。最后对影响外引树种的生态因子进行了关联度分析，提出了影响山西省外引树种生态适应性的主导因子及贡献排序。

Abstract: A systematic investigation including biological characteristics, ecological habits and environment factors of exotic tree species in Shanxi was carried out through the field method. According to the introduced theory of dominant factor, the analysis about different ecological factors in the process of introducing plant adaptability cultivation was performed. On this basis, the correlation degrees of ecological factors were analyzed. Finally, the key factors and contributions that will affect the growth of exotic tree species were put forward.
