Shuitu Baochi Xuebao, 2017 为了探究砒砂岩区不同造林树种水文特征，以该地区油松、侧柏、青杨、山杏、沙棘、柠条为研究对象，通过浸泡法和环刀法，对比分析了不同树种枯落物层和土壤层的持水特性。结果表明：砒砂岩区主要造林树种枯落物蓄积量变动范围为1.55~7.89 t/hm2，青杨林下枯落物最大持水率最高为281.26%，其他树种枯落物最大持水率依次为油松（217.14%）、侧柏（201.05%）、山杏（202.79%）、沙棘（170.96%）、柠条（158.08%）撂荒地（143.88%）。油松林下土壤层容重最小为1.46 g/cm3 ...

Shuitu Baochi Xuebao目的蓄水陶土作为一种新型土壤改良剂，其 对黄土高原土壤的水力特性影响如何尚未得知。为此研究不同粒径和添加量的蓄水陶土对土壤水力特性的影响。方法通过选取山西省太原市西山耕层的粉壤土为供试土壤进行室内物理试验，设置2种蓄水陶土粒径（M：2~5 mm，L：5~10 mm）和4种蓄水陶土添加量（0、5%、10%、20%），测定土壤水分特征曲线和饱和导水率，分析不同粒径和添加量下土壤的水力特性参数的变化。结果1）与不添加蓄水陶土的CK相比，添加蓄水陶土能够增强土壤的渗蓄能力。随着添加量和粒径的增加 ...
