摘要:
 以小陇山日本落叶松人工林为研究对象，运用全林整体生长模型对不同地位级日本落叶松人工林数量成熟龄、工艺成熟龄、经济成熟龄采伐年龄确定进行了初步研究。结果表明，小陇山3个地位级的日本落叶松林生均具有速生和分化快的特点；小陇山林区日本落叶松人工林的数量成熟龄主要集中在15~20 a;经济材的工艺成熟龄集中20~25 a，大径材在40 a时工艺成熟龄尚未达到，中径材为25 a，小径材为15 a; 经济成熟龄主要集中在15~35 a。因此，可根据日本落叶松人工林在不同地位级上的林木成熟年龄特征，指导确定小陇山林区不同地位级日本落叶松主伐期。
Abstract:
 Taking the Larix kaempferi plantations in Xiaolongshan region as research objects,the whole L.kaempferi stand model was used to analyze the maturity in quantity,in technique,and economic values.The plantations that belonged to three different classes presented the features of fast growth and differentiation.The quantity maturity age and technical maturity age were around 15-20 and 20-25 a,respectively.For big-diameter timber,the technical maturity age was more than 40 years,for middle-diameter timber and small-diameter timber,it was 25 and 15 a,respectively.The economic mature age was around 15-35 a.Guided by the mature ages established,the optimal timber harvest time of L.kaempferi plantations that were in different site classes in Xiaolongshan forest region could be determined.
