Shuitu Baochi Xuebao, 2019 川西亚高山原始针叶林遭受大规模采伐后自然恢复形成的次生林已成为该区域的主要森林类型之一，也是我国西南林区水源涵养林的重要组成部分。现有亚高山森林水源涵养功能研究主要集中在暗针叶林，对天然次生林关注较少。选择川西米亚罗林区亚高山次生林自然恢复演替序列上高山柳灌丛、次生桦木阔叶林、岷江冷杉桦木针阔混交林，以相邻岷江冷杉成熟林为对照，采用空间代替时间的方法，基于土壤容重、孔隙度、持水性能等测定，分析了次生林恢复过程中土壤物理性质变化及土壤水源涵养效应动态，结果表明：（1）次生林恢复过程中 ...

Shuitu Baochi Xuebao, 2017 为揭示喀斯特地区不同石漠化程度土壤理化性质特征及其影响机制，以贵州毕节石漠化地区土壤为研究对象，在雨季前、中、后对潜在、轻度、中度、强度石漠化程度的土壤进行了为期4年的监测，分析了不同石漠化程度土壤理化性质及其各项指标之间的相关性特征。结果表明：同一石漠化程度下，土壤有机质、全磷、有效磷、全氮和水解氮含量表现为雨季中＞雨季后＞雨季前。随着石漠化程度的加深，土壤田间持水量、毛管持水量、毛管孔隙度和总孔隙度升高，全磷、有效磷和有机质含量减少。与潜在石漠化程度相比，轻度 ...

Shuitu Baochi Xuebao, 2016 为了解坡面整地措施对坡体稳定性的影响和土壤物理性质对土壤抗剪强度的差异性，选取石匣小流域4个标准样地，通过测量多个土壤物理性质指标（土壤容重、土壤含水率、总孔隙度、毛管孔隙度、非毛管孔隙度、紧实度和液限），研究不同坡面整地措施的土壤临界剪切力随深度的变化，以及土壤抗剪切破坏能力的强弱关系和影响因素。结果表明：原状土的临界剪切力随深度的增加而增加；通过库伦公式得出的土壤抗剪强度与土壤临界剪切力的回归方程为：σ=0.0123τf+0.6308。土壤物理性质对抗剪强度的影响不同，紧实度 ...
