| 摘 要： | 以内乡宝天曼自然保护区为研究区域,选择不同海拔下的土壤为研究对象,通过野外采样和室内测试分析,研究土壤理化性质和酶活性的海拔异质性.结果表明:各海拔梯度土壤均为偏酸性土壤,按照全国第二次土壤普查养分分级标准,有机质含量较丰且在较高海拔位置处含量较高,各海拔高度全氮和碱解氮含量均较低,全磷含量处于中等以上的水平,有效磷含量处于缺或极缺水平,土壤全钾和速效钾含量属于中等以上水平.各土层的土壤脲酶、磷酸化酶与土壤各养分指标之间均无显著的相关关系,单一的土壤酶活性指标不能很好地代表土壤肥力状况.

| Abstract: | Physicochemical property and enzyme activities of soils at different altitude of Neixiang Baotianman Nature Reserve,Henan Province,were investigated.Results showed that all of soils were acidic.According to the soil fertility classification of the second soil census,organic matter content was abundant,and increased with altitude.At each altitude,content of the total nitrogen,alkali hydrolysable nitrogen and available phosphorus were low or very low.The content of total phosphorus,total potassium and available potassium content were above medium level.Moreover,correlation analysis showed no significant correlation between soil enzymes(urease and phosphorylase)and fertility factors.Therefore,single enzyme activity of soils should not be enough for reflecting soil fertility in Neixiang Baotianman Nature Reserve. |
