摘要:
 按照营造日本落叶松林立地条件进行划分，将适宜、较适宜和不适宜分为Ⅰ级、Ⅱ级和Ⅲ级。选择不同立地类型的幼、中、近、成4个林龄段的典型日本落叶松林分在2008年分别设置面积为20 m×30 m的样地， 2013年和2015年进行了复测，固定样地取自未被人为干扰及未遭受自然灾害的自然生长的林分样地33块，采用ForStat2.2软件进行拟合计算。建立了小陇山林区人工日本落叶松林的8个林分整体生长预测模型，各参数的平均相对误差和相对均方误都<6.5%。获得的全林整体模型可对小陇山林区不同条件下的日本落叶松林分的生长进行预测，可对间伐进行预测分析，绘制不同立地指数条件下的林分密度控制图，从而指导小陇山林区日本落叶松林分的经营活动。
Abstract:
 The site conditions of building Larix kaempferi were divided into three levels: most suitable (Ⅰ),suitable (Ⅱ),not suitable (Ⅲ).Sampling plots,each with an area of 20 m×20 m,were established in 2008 in the typical L.kaempferi plantations with different development stages: young,middle,nearly mature,and mature.Data were extracted repeatedly in 2013 and 2015.Fixed sampling plots with a number of 33 were selected from those in which no human disturbance or natural disaster occurred.The software ForStat2.2 was adopted to establish the whole development model of 8 L.kaempferi stands.The mean relative error and relative mean square error of each model were less than 6.5%.The growth of L.kaempferi plantation under different conditions in Xiaolongshan region was predicted though the whole stand model.The thinning was predicted and analyzed.The stand density control diagram was drawn under different site index conditions.So management activities of L.kaempferi plantation in Xiaolongshan region were guided by the model.
