Shuitu Baochi Xuebao, 2011 人参生长的土壤理化环境决定人参的产量,良好的土壤结构能防止土壤侵蚀。试验研究了人参床土的土壤结构及持水性能,分析了老参地土壤物理性状恶化的原因,测定了人参床土颗粒组成、中干团粒、湿团粒、水稳性团聚体、微团聚体占干土重的百分含量及结构破坏率。结果表明:人参床土以物理性砂粒(>0.01mm)为主,约占49%～63%,质地属于砂壤土。人参床土中>1mm干团粒、0.5～2mm水稳性团聚体、>0.01mm微团聚体与产量具有显著的相关性。床土的总孔隙度为55.78%～72.69%,总孔隙度 ...

Shuitu Baochi Xuebao目的探讨采煤塌陷区地裂缝对土壤水分运移规律的影响，揭示其运移机制，并阐明植被与土壤理化性质在该过程中的调控作用。方法以曹家滩矿区的典型植被［沙蒿（Artemisia desertorum）、早熟禾（Poa annua）、生物结皮］作为研究对象，采用双环入渗仪和微型蒸渗仪，监测不同处理下土壤水分的入渗率和蒸发特征。结合土壤理化性质（体积质量、孔隙度、机械组成等），分析不同植被-土壤系统下地裂缝对水分运移的影响机制。结果1）采动地裂缝对周边土壤水分运移产生显著影响 ...

Shuitu Baochi Xuebao, 2002 通过对影响土壤渗透的多个因素的测定，研究了石质山地不同土壤不同层次的渗透能力，不同水温对渗透的影响，渗透筒不同插入深度对渗透的影响，由此可以得出，土壤的渗透能力是由各立地条件的土壤理化性质决定的。影响土壤入渗性能的最主要因素是土壤的总孔隙度和非毛管孔隙，这与土壤容重和土壤含水量也有很大关系。入渗与水温表现为较好的线性关系。
