The Ecological Adaptation Evaluation Of The Introduced Species Of Shanxi Garden Based On The Dominant Factor Analysis

This paper has made a systematic investigation for the biological characteristics, ecological habits and life force of landscape trees in Shanxi using field survey method. According to the theory of dominant factor introduction, it analyzes the dominant factor that influences the ecological adaptability of introducing landscape trees in Shanxi, and the different ecological factors that play in the process of introducing adaptive cultivation. It makes correlation analysis on ecological factors affecting external species, in order to understand the situation of external species and the adaptability evaluation of tree species in Shanxi Garden, and accelerate the development of the process of introducing city landscape greening tree species. In that, it expands the introduction and vision, and riches the diversity of city greening tree species.Using the grey correlation analysis method, it analyzes dominant ecological factors on the planting and origin area. It shows that the key factor that affects the tree introduction in Shanxi area is the extreme low temperature and annual precipitation.
