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。
In this paper, the annual growth of Pinus koraiensis was analyzed with the growth of Pinus koraiensis and the regression of 23 climatic factors. The results showed that the growth of Korean pine was closely related to the average temperature in July, ≥5 ℃ accumulated temperature and annual precipitation. Based on these three climatic factors, the suitable zonation of growth of Korean pine was comprehensively divided into three regions: unsuitable growth area, suitable poor area and suitable area. This is consistent with the actual distribution area of Korean pine. It fully proves that the distribution of Korean pine is compatible with the climate. It further illustrates that the Korean pine broad-leaved forest is a stable zonal plant community in this area. Korean pine growth suitable for regional zoning, artificial korean pine forests will also provide some scientific evidence.
