摘要
The annual mean temperature and other 10 climatic factors were selected as the main factors for comparison by using the method of Euclidean fuzzy distance similitude priority ratio. The sequence of similarity degree of climatic and ecological conditions of 126 cities or stations in China and of the main persimmon production region in Japan were analyzed by QBASIC programme. And the China’s suitable climatic and ecological region for introducing Japanese sweet persimmon ( Diospyros kaki ) were divided in the light of practical introduction and cultivation experiments. The authors divided China into 3 climatic and ecological regions according to their suitability for cultivating Japanese sweet persimmon.
