DIVISION OF FOREST CLIMATIC REGIONS IN HAINAN ISLAND BY STEPWISE DISCRIMINATORY ANALYSIS

On the basis of flora classification, eleven forest climatic factors with close relation to the tropical forestry were selected as an index for the regional division. The Oidham distance coefficient was adopted for the predetermining classification, using stepwise discriminatory method for analysing and the classified division was tested.
