摘要
为研究林分密度动态变化规律提供一个理论参考水平，且为合理经营森林提供一种确定林分极限密度的较佳方法，本文以长白落叶松（ＬａｒｉｘｏｌｇｅｎｓｉｓＨｅｎｆｙ）人工林为研究对象，在设置的３６块标准地上采用重复抽样的方法。每块标准地随机抽取２０个样方、在保证各样方株数分布为正态分布的前提下，引入顺序统计量分布的理论．采用抽象化的方法确定各标准地的林分极限密度。利用Ｒｅｉｎｅｋｅ公式ＩｎＮ＝Ｋ十β１ｎＤｇ进行回归，得出林分极限密度线斜率为β＝－１．１４５７９。
Based on larch (Larix olgensis Henry) plantations, repeation sampling method was used on 36 plots and for each plot, 20 samples were taken out using random sampling. On the condition that the individuals on plots show normal distribution, the theroy of orderly statistical distribution was used. The limited stand density of the sample plot was determined by abstractlization method. Using the Reineke equation InN=K+ glnDg, the slope of limited stand density line was β=-1. 14579. Thus it supplied a theoretical reference basis for the stand density dynamics and a better method of determining the limited stand density for the reasonable management.
