| 摘 要： | 本文论述了如何以效应生长量分析为基础,通过对华北落叶松人工林间伐林分的研究,建立与间伐有关的系列断面积收获预估模型。以此为基础,提出了一套确定抚育间伐强度和预测目标径级收获量的具体方法.通过对伐前密度为5550株·hm~(-2),地位指数级为10的华北落叶松人工林的研究,提出了间伐起始期15a,间隔期5a,采取4次间伐,间伐株强分别为30.3％,17.1％.22.4％,7.8％的间伐体制。

| Abstract: | A yield model for sequential estimation of basal area in stand in relation to thinning cut was established by analyzing the response increment. Based on the model, a series of instructions to determine the intensity of tending cut and to predict the yield of goal diameter were put forward. For the studied larix principis - rupprechtii plantation with site index of 10 and stand density of 5550 trees per hectare,the initial stage for thinning -15 years with interval of 5 years and the thinning intensities according to tree number-30. 3%, 17. 1%, 22. 4% and 7. 8%for the consecutive 4 cut were suggested. |
