摘要
文中用200块临时样地、2块全林树干解析皆伐样地的数据,建立了长白落叶松人工林林分密度效应模型,用动态规划的方法找出了最优密度,并对其抚育间伐技术进行了研究,编制了建筑材采伐表、出材量表及经济收益表。
Stand effect models of Larix olgensis plantations were fitted using 200 temporary plots and 2 clear cutting plots of stem analysis.The optimal stand density were found by the method of dynamic programing.Techniques of thinning were experimented.Tables of cutting,stand outturn and economic yields for building wood were constructed.
