摘要
为研究天然落叶松林的树种组成，对黑河地区１２２块样地的蓄积量和生长量进行聚类分析，并对分析结果和树种组成进行频率分析。研究结果表明：要保证天然落叶松林的高产，落叶松在林分中的比例应占绝对优势，但不完全是１００％。落叶松断面积在阴坡应控制在９０％～９５％，在阳坡应控制在８５％～９０％；落叶松株数在阴坡应控制在８６％～９２％，在阳坡应控制在８０％～８５％
The volume and increment of larch stand in 127 experimental plots in Heihe District were systematically analyzed. The frequency analysis was also made on analyzed results and tree components. The research result indicated that, concerning tree species components, larch should be the dominant but it must not reach 100% for high-production stand. The basal area proportion of Dahurian larch should be controlled to 90%-95% on shady slope and to 85%-90% on sunny slope. The tree number proportion of larch should be controlled to 80%-92% on shade slope and to 80%-85% on sunny slope.
