摘要: 利用主成分分析法(PCA)和多组判别分析法(MGDA)研究了东北地区城市地带性植被类型判别模型:①以东北地区210个城市(镇)个气象因子为变量,组成210×7矩阵,用PCA方法进行分类和排序,其结果明显划分个城市(镇)地带性植被类型;②影响城市(镇)地带性植被类型分布的气候因子,主要是热量和水分条件以及二者的综合状况;③采用MGDA法建立了东北地区城市地带性植被类型判别函数模型,预测城市地带性植被类型;④确定城市(镇)地带性植被类型,并提出了3种城市森林生态建设模式,为城市森林生态建设提供科学依据.

Abstract: Discriminant model of urban zonal vegetation types in Northeast China was established with principal component analysis(PCA)and multiple group discriminant analysis(MGDA). The results showed that 210?7 matrix was established with variables of 210 cities(towns)and 7 climate factors. According to classification and ordination from principal component analysis, there were obviously 7 city(town)zonal vegetation types.Temperature, moisture and their integrate situation the main climate factor influencing distribution of city(town)zonal vegetation types. Discriminant function model of urban zonal vegetation types in Northeastern China was established with multiple group discriminant analysis, and predicted urban zonal vegetation types. Urban zonal vegetation types were validated, and 3 urban forest ecological construction models were put forward.The study provided scientific basis for urban forest ecological construction.
