摘要
文章选择了１９５２年斯珀尔提出的评价林分密度的四个标准，对国内外现有的十二种密度进行了综合评价。林分密度指数（ＳＤＩ）、相对密度（ＲＤ）、树冠竞争因子（ＣＣＦ）、树木面积比和点密度既能反映树冠平均生长，又与林分疏伐直接相关，并为描述林分最大密度，预测死亡率，以及林分疏伐时最佳林分密度的确定等提供了方便的尺度。
According to the standard of evaluating stand density measures first proposed by Spurs in 1952,twelve measurs are reviewed and appraised comprehensively.Some measures of stand density such as stand density index, relative density,crown competition factor, tree-area ratio and point density not only indicate thecrow average growth. but also are directly correlative with thinning, and provide convenient measures in describing maximum stand density, predicting mortalityprobabilities and dertermining the best stand density of thinning.
