9.The summit of DBH distribution curve was all partial to left, but the skewness of shady slope forest (SK=0.75) was lower than that of sunny slope forest (SK=1.03), and the kurtosis of shady slope forest (K=1.05) was higher than that of sunny slope forest (K=0.94), indicating that sunny slope forest had a larger stand density than shady slope forest.
两种林分直径分布都呈现顶峰左偏(林分密度偏大)的现象,但阴坡林分的偏度系数(SK为0.75)小于阳坡林分(SK为1.03)、而峰度系数(K为1.05)大于阳坡林分(K为0.94),说明阳坡林分密度偏大的程度大于阴坡林分.收藏指正
