摘　　要：人工同龄纯林树冠面积比例系数计算及林分标准密度（立木株数）确定的研究熊奎山（甘肃省林业勘察设计研究院兰州７３００２０）关键词人工同龄纯林，树冠面积比例系数，林分标准密度确定Ｒｅｉｎｅｋｅ（１９８３）指出：具有完满立木度的同龄纯林，具有相同的单位面积株...? The crown area proportional coefficient of pure artificial even aged stand means the ratio of the area of the stand to its crown. Standard density refers to the theoretical density of the pure artificial even aged stand area when its crown density is 1.0. According to the method of studing the forest site classification and evoluation in Nanling mountainous region, when the arrangements of forest tree in a stand are the rectangle and isosceles triangle, the crown area proportional coefficient and range of its variation have been concluded in this paper, if canopy density is 1.0. And we calculate stand standard density (stem number) of two kinds of arrangements, which provides the scientific bases for precisely determing the standard density and quantitative intermediate cutting of a pure artificial even aged stand.
