黑土区水蚀坡耕地土壤穿透阻力时空变异特征及传递函数

Shuitu Baochi Xuebao
[目的] 为探明侵蚀坡耕地黑土硬度的时空特征及关键驱动因素。[方法] 基于典型水蚀坡耕地110个样点土壤穿透阻力动态监测及其相关因素的测定,在阐明土壤穿透阻力时空特征的基础上,利用多元线性回归(MLR)和随机森林(RFR)模型分析土壤穿透阻力的影响因素,并进一步构建其传递函数。[结果] 土壤穿透阻力时空变异性受土层深度、水分条件及农事活动等因素的综合影响,耕作层土壤穿透阻力空间上的异质性显著低于亚表层,变异系数分别为17.4%和26.3%。随土壤由湿变干和距离翻耕的时间增加,空间异质性呈增强趋势 ...
