摘要
本文研究了石灰岩发育土壤的孔隙状况及与淡竹林分胸径和高度之间的相关关系。研究指出：石灰岩发育的土壤其孔隙状况差异较大；淡竹林分平均胸径、优势胸径、平均高和优势高与土壤非毛管孔隙度和总孔隙度之间存在着明显的二次回归曲线关系，与毛菅孔隙度间的相关性不明显；3个土壤孔隙因子对淡竹生长的综合影响非常显著，其中非毛营孔隙度的影响最大，总孔隙度次之，毛菅孔隙度的影响相对较小。
The relationship between porosity of limestone soil and diameter and height of ph. glauca McCl. are studied in this paper. The following conclusions are obtained: (1)The porosity of limestone soil is very different. (2)The regression relationship between the diameter height of Ph. glauca and the non-capillary porosity,total porosity of limestone soil is very obvious. (3)The influence on Ph. glauca growth is: non-capillary porosity>total porosity>capillary porosity.
