| 摘 要： | 通过对金佛山地区不同生境下土壤有机质和全氮含量的测定表明，0～10 cm土层内，有机质含量的顺序为西坡(108.088 g/kg)>南坡(92.229 g/kg)>山顶(89.727 g/kg)>北坡(80.881 g/kg)，全氮含量的顺序为山顶(6.482 g/kg)>南坡(92.229 g/kg)>西坡(4.355 g/kg)>北坡(3.928 g/kg)，土壤C/N顺序为西坡(24.82)>北坡(20.59)>南坡(16.12)>山顶(13.84)；10～20 cm土层内，有机质含量的顺序为山顶(93.895 g/kg)>西坡(70.319 g/kg)>南坡(67.970 g/kg)>北坡(63.255 g/kg)，全氮含量的顺序为山顶(5.528 g/kg)>西坡(4.055 g/kg)>南坡(3.867 g/kg)>北坡(3.460 g/kg)，土壤C/N顺序为北坡(18.28)>南坡(17.58)>西坡(17.34)>山顶(16.99)。不同生境之间的土壤有机质和全氮含量存在差异，且0～10 cm土层高于10～20 cm土层。土壤有机质和全氮含量之间呈显著正相关。

| Abstract: | The contents of organic matter(OM),total nitrogen(TN) and C/N ratio of soil under different habitats in Jinfo Mountain were studied and the results showed that the order of OM content in 0 to 10 cm soil layer was west slope(108.088 g/kg)>south slope(92.229 g/kg) >summit(89.727 g/kg)>north slope(80.881 g/kg).The order of TN content was summit(6.482 g/kg)>south slope(5.722 g/kg)>west slope(4.355 g/kg)>north slope(3.928 g/kg).The order of C/N ratio was west slope(24.82)>north slope(20.59)>south slope(16.12)>su... |
