| Abstract: | Vernicia fordii, distributed and planted in 15 provinces and regions inSouth China, is an important industrial oil tree. 82 production counties whichare different in climatic conditions have been sampled. Principal componentanalysis is applied to reduce 18 original variables to six new variables,and the method of cluster anaiysis is used to classify the tung oil treeproduction areas in China into 3 climatic regions and 7 climatic subdivisions.The study facilitates a reference to the layout of the development of tungoil tree plantations. |
