Shuitu Baochi Xuebao, 2008 运用空间代替时间的方法研究了25年生柳杉人工林(对照)采伐后形成的柳杉人工幼龄林、经济林、苗圃地、皆伐迹地、农耕地5种土地利用类型初期土壤有机碳含量和碳储量变化。结果表明,5种土地利用类型和对照的土壤有机碳含量和碳储量均随土层的加深而降低;除经济林外,苗圃地、柳杉人工幼龄林、农耕地和皆伐迹地的土壤平均有机碳含量分别比对照降低了10.8%,28.1%,37.8%,40.1%;5种不同土地利用类型土壤碳储量排序为:皆伐迹地(214.2±17.0 t C/hm2)>经济林(191.3±13.4 t C/hm2)

Shuitu Baochi Xuebao, 2017 通过野外调查与室内试验相结合的方法，选取不同坡度（10o，15o，20o）的针阔混交林、灌木林、园地、坡耕地、荒地5种土地利用类型，观测土壤抗剪强度指标、含水率、容重、干密度、总孔隙度、有机质、土壤团聚体MWD值（干筛和湿筛），运用模糊贴近度法和逐步回归分析法分析影响不同土地利用类型土壤抗剪强度的因素。结果表明：相同土地利用类型土壤黏聚力随着坡度的增加先增大后减小；在针阔混交林中，团聚体湿筛MWD值与土壤黏聚力的贴近度最大，在荒地中则是有机质，而在其他3个土地利用类型 ...
