| 摘 要： | 本文采用数量化理论Ⅰ的方法,分析和比较了生态因了对云南松林上层木生物量的作用强度.共选择生态因子九个、即上类,土层厚度,坡向,坡位,坡形,海拔,林龄、林分密度和平均树高.结果表明,影响云南松树生物量的主要生态因子为林龄,林分密度、坡位、坡向和平均树高.但生物因子的作用比生境因子更强烈.

| Abstract: | By applying the method of quantification theory I , effect of ecological factors on the biomass of overstroey trees in the pine ( Pinus Yunnanensis) forest has been analysed and compared. Nine ecological factors: soil classification, soil depth, slop orienation, slop location, slop shape, height above sea level, stand age, stand density and average height, are choosed. This study shows that important ecological factors affecting the biomass of pine are stand age, stand density, slop orientation, solp shape and average height respectively. The effect of biotic factors on the biomass is much stroger than habitat factors on it. |
