【目的】对比分析天山北坡不同下垫面融雪期积雪特性（积雪深度、积雪密度、液态含水率、雪层温度）及其影响因素。【方法】通过对融雪期林地、草地、裸地积雪特性、气象因子（气温、太阳辐射、空气相对湿度）和土壤因子（土壤含水率、土壤温度）等数据进行实时监测，利用Pearson相关分析方法对比分析气象因子、土壤因子与3种下垫面积雪特性间的相关性。【结果】融雪期林地、草地、裸地平均积雪深度分别为8.06、18.67、16.34 cm；林地积雪层平均积雪密度、平均液态含水率均大于草地和裸地，分别为0.48 g/cm3、0.66%；林地平均积雪层温度（-0.032 ℃）均小于草地、裸地；融雪期裸地积雪深度与太阳辐射显著负相关，相关系数为-0.960；草地积雪密度与太阳辐射显著正相关；裸地积雪密度、液态含水率、积...
