摘要：本文通过对长白山脉西部蛟河林场３２ｈｍ２原始红松阔叶林中７７个林隙的调查，研究了红松阔叶林中１３个主要乔木树种对林隙大小和发育阶段的更新反应规律。结果表明：树种更新密度随林隙大小的变化呈现出单峰型的反应，除沙松、紫椴和花楷槭在林隙面积为４０～６０ｍ２时更新密度最大外，其它１０个树种的更新密度都在林隙面积为２０～４０ｍ２时最大。树种更新密度对林隙发育阶段有单峰型、双峰型和变化不明显３种反应类型。所有树种在林隙内的更新密度都大于其在非林隙林分下的密度。
Through investigation of 77 gaps in a 3.2hm 2 virgin old growth Korean pine broadleaved forest in Jiaohe forest farm,regeneration responses of 13 main tree species to gap size and gap developmental phase were studied.The result showed that the regeneration densities of trees changed with gap size,revealing a unimodal curve.Regeneration densities of three tree species among the 13 peaked at the gap size of 40～60m 2,while those of the other 10 species peaked at the gap size of 20～40m 2.The responses of tree species to gap developmental phase revealed three types i.e.the unimodal curve type,the double modal curve type,and the no significant response type.The regeneration density of each tree species in gaps was greater than their corresponding regeneration density in non gap stands.
