| 摘 要： | 将土壤水分含量和电导率作为分析土壤特性的随机变量,分析了小柴旦盐湖盆地不同深度土壤层(0 ～20、20～40、40～60、60～ 80、80 ～ 100 cm)的经典统计和地统计特征,比较了不同土地利用类型和不同深度的土壤水分含量和电导率的空间变化特征.结果表明:土壤电导率大体表现为由南北向中心减小的趋势,在垂直方向上无明显变化规律,其变异系数有由表层向下逐渐减小的趋势；土壤水分含量从北向南有增大的趋势,在垂直方向上由表层向下逐渐增大,其变异系数由表层向下逐渐减小.

| Abstract: | By taking soil water and conductivity as random variable of the soil characteristics,this paper analyzes classical statistical and geo-statistical characteristics of different depth of soil layer in Xiaochaidan salt lake basin,and also the soil water and conductivity's space characteristics of different land use type and soil layer.The results show that a) soil conductivity has the reduction trend from south and north to the center,and no obvious change rule in the vertical direction,but the coefficient of ... |
