Abstract: Model of climatic potentiality of forest is established through Logistic curve of plant growth．The climatic potentiality of korean pine and the impacts of climatic change on climatic potentiality in Northeast China are calculated and analyzed by using meteorological data in different years．The results show that the highest volume of climatic potentiality of korean pine is 288m³／hm² and its lowest volume is only l15m³／hm²，the difference between the highest and lowest volumes is more than 1 times ．The impact of different climates on climatic potentiality is remarkable．
