摘　　要：以吉林省汪清县金沟岭林场落叶松人工林为研究对象,利用混交度、大小比数和角尺度3个林分结构参数,分析其不同龄组空间结构。结果表明:各龄组的样地混角度均为0.5,处于中度混交;中龄林为均匀分布,近熟林为团状分布,成熟林为团状或均匀分布;中龄林中落叶松处于中庸状态,大部分阔叶树处于中庸或劣态,近成熟林中落叶松和阔叶树逐渐转为亚优势状态。With the Larix gmelinii plantations in Jingouling forest farm of Wangqing county, Jilin province as the research object, by using three stand structure parameters （ mixed degree （/14） and angle measurement, size score （W）, the space structure ofL. gmelinii of different age-groups were investigated and analyzed. The results show that the sample M values in each age-group were 0.5, being a moderate mixed plantation; the mid-maturation forests showed uniform distribution; the near-mature forests distributed with reunion distribution; The mature forests took on patches or uniform distribution; the mid-maturation larch forests were in the doctrine of the mean state, the most broad leaved tree were in the middle or inferior state; the near mature larch forests and hardwood trees gradually transferred into the advantage status.
