对10年生连香树人工群落与环境关系的研究表明，土壤中有机质、有效Ca、Fe、Ms和N之间有较强的相关性；土壤有效元素除N和Mn外，一般都不直接影响群落对土壤中各对应的有效元素的吸收和积累．连香树在不同生境条件下，对土壤元素的吸收有一定的选择性．影响连香树地径、胸径、树高和生物量的因子顺序表现为土壤化学性质＞土壤物理性质＞气候因子；土壤有效P对连香树生长的影响小．连香树适宜生长在海拔 2200～2700m，且土壤疏松多孔、富含有机质、自然含水率较高以及空气平均湿度较大的区域．

The relationship between 10 years old C. japonicurn plantation forest community and its environmental conditions was studied by grey correlation method and cluster analysis. The reuslts showed that there existed closer relations a mong soil organic matter, available Ca, Fe, Mg and N. Except for N and Mn, all soil available elements tested had no di reet impact on the absorption and accumulation of corresponding elements by the community. The tree species in differ ent habitats was found to absorb soil elements selectively to some extent. The factors affecting the basal diameter, DBH, height and biomass of C. japonicum could be lined as soil chemical characteristics ＞ soil physical properties ＞ cli mate factors, in which, available P had little impact on the growth of C. japonicum. It is suggested that C. japonicum could be restored in the ares with higher air moisture and with fertile porous soil between elevation of 2200 ～ 2700m.
