| 摘 要：本文通过在鼎湖山不同海拔梯度上各林型的土壤采样，研究了鼎湖山土壤化学性质对海拔梯度的响应。结果为：（1）鼎湖山土壤剖面C层随着海拔梯度的上升，土壤酸度降低。（2）鼎湖山位于海拔低的赤红壤的NH4-N，全钾，速效钾，交换性Na，交换性钾，交换性Mg和阳离子含量比位于海拔高的黄壤的对应养分含量要高。（3）鼎湖山土壤二氧化硅，锰含量随着海拔梯度的上升而下降，赤红壤含量高于黄壤；然而铁含量则随着海拔梯度的上升呈上升趋势，赤红壤含量低于黄壤，钙全量含量和磷含量也是赤红壤低于黄壤。（4）土壤Pb马尾松林含量最高，随着海拔梯度上升含量有下降趋势。土壤其它微量元素含量与海拔高度没有明显的相关关系。 |

| 摘 要(英文)：By sampling soils in different forest types，this paper studies the responses of soil chemical properties to altitude at Dinghushan. The results are：(1) The higher of altitude，the less of soil acidity in soil C horizon at Dinghushan；(2) There are more NH4-N，total K，available K， exchangeable K，exchangeable Na，exchangeable Mg and the content of exchangeable cations in lateritic red soil at low altitude than those in yellow soil at high altitude；(3) With increasing altitude，the contents of sio2 and Mn decrease，and the concentrations of this two minerals in lateritic red soil are higher than those in yellow soil. While it is contrary that the more contents of Fe，Ca and P are in yellow soil at higher altitude than those in lateritic red soil；(4) The pine forest has the highest content of Pb，and the Pb content is higher in soil at low altitude than that in high altitude. Other microelements are no evident correlativity with altitude. |
