摘　　要：通过云南普朗铜矿典型植被覆盖下土壤温湿度原位监测,结合气象资料,分析雨季矿山表层土壤温湿度时空分布特征及其与气象要素的环境响应机制。结果表明:随着土层加深,土壤平均温度逐渐减小,土壤温度波动性减小;土壤温度并不随着海拔的升高而降低,3950 m林地土壤温度小于4150 m草地处,植被覆盖可以保持土壤温度的稳定性;浅表层土壤水分整体上较深层水分高,土壤平均湿度从高到低的顺序为林地、草甸、草坡;各深度土壤温湿度皮尔逊相关系数达0.6以上,土层深度越深,土壤温湿度相关关系越强;各层土壤温度与气温的相关系数达0.8以上,越靠近地表,土壤温度与气温相关关系越强;土壤湿度与降雨的相关系数在0.47~0.60之间。Through in situ monitoring of soil temperature and humidity under typical vegetation coverage in Pulang copper mine in Yunnan Province,combined with meteorological data,the spatial and temporal distribution characteristics of soil temperature and humidity in the mine surface during the rainy season and its environmental response mechanism with meteorological factors were analyzed.The results show that the average soil temperature decreases gradually,and the fluctuation of soil temperature decreases with the deepening of soil layer.The soil temperature does not decrease with the increase of altitude,and the soil temperature of 3950 m woodland is less than that of 4150 m grassland,and the vegetation coverage can maintain the stability of soil temperature.The soil moisture in the shallow surface layer is higher than that in the deeper layer as a whole,and the average soil moisture is in the order of woodland,meadow and grass slope from high to low.The Pearson correlation coefficient of soil temperature and humidity in all depths amounted to more than 0.6,and the deeper the depth of the soil layer,the stronger the correlation of soil temperature and humidity.The correlation coefficient of soil temperature and air temperature in all layers amounted to more than 0.8,and the closer to the surface,the stronger the correlation of soil temperature and air temperature.The correlation coefficient of soil moisture and rainfall is between 0.47~0.60.
