摘要
在对红松适生范围、生态习性等广泛深入调查分析基础上,依据环境因子对树木生长影响的作用规律,首先推出一个能反映红松年生长量与水热因子间关系的W-T模式,进而分析了各种可能的气候变化对红松生长量与分布的影响。结果表明,气温升高,无论降水增减,都将使红松适生范围与生长量大幅度减少。但在可预见的气候变化范围内,红松不会退出我国的东部山地。
In this paper, the distribution and ecoiogical characteristics of Korean Pine is analyzedand a W──T model is built based on the effects of environmental factors on tree growthand necessary presumptions , the influence of various climate changes on the growth and dis-tribution, and the annual growth of Korean Pine under different climatic conditions, The re-sults show that the suitable area and the growth of Korean Pine will greatly decrease in re-sponse to the temperature rising no mater how the precipjitation changes( increse or decrease).In perceptible ranges of climate changes, Korean pine would not recede from the northeast China.
