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 ...

基于改进稳定映射法的云南省土壤侵蚀强度变化轨迹及其驱动因素

Shuitu Baochi Xuebao
目的揭示云南省1990—2022年土壤侵蚀强度的变化轨迹，分析其变化类型及驱动因素，为制定有效的土壤侵蚀防治策略提供科学依据。方法基于RUSLE模型定量评估云南省土壤侵蚀强度状况，并引入年际变化速率捕捉其动态特征；采用改进的稳定映射法(STD)，结合变化速率和变化频率，识别土壤侵蚀强度变化轨迹类型；利用随机森林模型分析驱动因素的贡献度，并比较不同轨迹类型分区的驱动因子特征。结果1) 云南省土壤侵蚀年际变化趋势以基本稳定为主，大幅减少和大幅增加区域面积变化显著；2)土壤侵蚀强度变化轨迹呈显著空间分异 ...
