Abstract: Through an analysis of the growth of the annual ring of Pinus Koraiensis the progressive regression of Pinus Koraiensis production and 23 climatic elements was made. The result shows that the production of Pinus Koraiensis closely correlates with the average temperature of July, the cumulative temperature of ≥5℃ and the annual precipitation. According to the three climatic elements mentioned above, the suitable districts for the growth of Pinus Koraiensis are demarcated into three kinds: suitable, relatively poor, and unsuitable regions. These three kinds of regions are fit for the actual distribution of Pinus Koraiensis. It seems to prove that the growth of Pinus Koraiensis is suitable to modern climate. The mixed broadleaved trees-Pinus Koraiensis forest is a stable climate in the mountainous region of Northeast China. This result also provides a scientific basis for the distribution of the artificial Pinus Koraiensis forests.

Key words: zonal community, progressive regression, Pinus Koraiensis distribution area
