摘要: 利用改进的ZELIG.CBA模型模拟了长白山杨桦林的动态变化过程.根据红松种源的存在与否,将模拟分为两种方案,结果表明,红松参加演替与否决定了山杨、白桦退出林分时间的早晚;红松种源存在时,演替的最终结果是阔叶红松林;无红松种源时,演替的最终结果是阔叶混交林,两种林分的生物量和蓄积量相差很大.

Abstract: The dynamics of polar birch forest in broad leaved Korean pine forest zone in Mt.Changbai was simulated by the validated ZELIG.CBA model. Based on the seeds sources of Korean pine available or not, two schemes were adopted.The results show that Korean pine determined the time when polar or birch would be replaced.If the seeds of Korean pine were available, the final stage of succession would be the broad leaved Korean pine forest.Otherwise, it would be a mixed broad leaved forest.The biomass and the volume of these two kinds of forest were quite different.
