摘要: 本文通过红松年轮生长分析,用红松年生长量与23个气候因子逐步回归。结果表明:红松生长与7月平均温度,≥5℃积温,年降水量密切相关。根据这3个气候因子综合进行红松生长量适宜性区划,划分出:红松生长不适宜区,适宜较差区,适宜区3个区域。这与实际红松分布区域是吻合的。充分证明了红松的分布与其气候相适应,更进一步的说明了红松阔叶林是该地区的一种稳定的地带性植物群落。红松生长适宜区的区划,对人造红松林也会提供一定的科学依据。

关键词: 生境, 逐步回归, 红松林分布

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
