摘要: 本文通过≥℃的生长度日(Growing degree-days)和潜在蒸散率(PER)建立水-温影响函数(f(PER,GDD))评价阔叶红松林分布区的气候适宜性,结合GCMs气候变化情景分析阔叶松林分布对气候变化响应。结果表明:随着气候变暖,阔叶红松林分布范围将缩小,南界北撤,分布区适宜性下降。同时,运用林窗模型(ForestGapModel)模拟不同气候情景下云冷杉阔叶红松林的动态变化。模拟显示:不同的气候变暖幅度在决定阔叶红树林结构组成和生物量上起重要作用。GISS和OSU情景下,云冷杉阔叶红松林将逐渐向枫桦紫椴阔叶红松林演变,而GFD和UKMO情景下,云冷杉阔叶松林向蒙古栋、紫椴、裂叶榆等阔叶树种组成的阔叶林演变。

Abstract: Based on the establishment of water-temperature function with GDD(Growing degree-days) and PER(Rate ofpotential evapotranspiration), this paper analyzed climatic suitability of current distribution of broad-leaved Pinus koraiensis forests and assess responses of the distribution to climate change(GCMs scenarios).The result show that distribution area of broad-leaved Pinus koraiensis forests will shrink greatly, and climatic suitability decreasewithin the area, and the southern boundary of the forests shift northward about l~2 latitude degrees under fourclimate change scenarios. By using Forest GaP Model, the dynamic responses of the forests to climate change aresimulated. Within 4℃ warming, the biomass(t/hm2), especially the biomass of Ptnus koraiensis, increase quickly,and biomass of some coniferous species, such as Picea jzoensis and Ables nephrolepis, will decrease and somebroad-leaved species increase during 100 modelling years. When warming over 4℃, the biomass decrease greatly,and Pinus koraiensis and other coniferous species will be replaced by broad-leaved species, and broad-leaved Pinus koraiensis forests change to broad-leaved forests.

Key words: broad-leaved Pinus koraiensis forest, response of global climate change, forest gap model
