摘要
本研究选择不同海拔的高寒草甸为研究对象,对不同海拔梯度温度、湿度及土壤养分进行了研究,研究结果显示:随着海拔的逐渐升高,地表温度逐渐降低,土壤湿度逐渐增大,土壤养分含量总体变化规律不明显,土壤全钾含量与温度呈负相关关系,且达到显著水平。
This study choose different altitude as the research object, alpine meadow of different elevation gradient temperature, humidity and soil nutrient was studied. The results showed that： with the rising of altitude, the surface temperature gradually decreased, soil moisture increased gradually. The soil nutrient content change law is not obvious, negatively related with temperature, reached significant level.
