四川盆地西缘中低山土壤质量研究及利用措施探讨

Shuitu Baochi Xuebao, 2006
以四川盆地西缘中低山坡地为研究样地，根据实际地貌特征分别选取3个典型山体、2个典型土壤类型。山体坡面不同坡位下土壤质量综合指数（PI）研究表明土壤质量指数随山体坡面位置相对海拔高度的降低而增高。不同利用方式下土壤质量综合指数（QI）研究表明，人工林的土壤质量指数值显著偏高，坡耕地的指数值最低。中低山坡地土壤质量的变化特征主要依赖于土地利用与覆盖之间的差异。故必须加强坡耕地规范治理，实施植被保护与重建等一系列土壤资源持续利用措施，实现土壤质量的持续健康发展。

重庆市典型工程堆积体边坡物理力学变化及稳定性特征

Shuitu Baochi Xuebao, 2017
：以重庆市城镇建设活动形成的典型工程堆积体为研究对象，对工程堆积体边坡物理力学特性和入渗特征进行了研究，同时确定工程堆积体边坡的危险滑动面及安全系数。在工程堆积体边坡上、中、下设置采样点，采集土壤样品进行土壤物理力学性质分析，采用野外双环入渗法进行入渗过程研究，运用GEO-SLOPE软件分析工程堆积体边坡稳定性。结果表明：（1）工程堆积体粒度分布不均匀，且中坡位>下坡位。（2）工程堆积体饱和含水量随坡位下降呈逐渐增加趋势；入渗率随时间变化呈快速减小、缓慢减小、稳定入渗3个阶段，2 m、2 a和4 ...

桥山林区不同林分和坡位土壤水分对典型降雨的响应

Shuitu Baochi Xuebao
目的降雨是土壤水分补给的主要来源，直接影响着土壤水分的分布特征，进而影响植被的生长状况，为探明桥山林区不同林分和坡位土壤水分对典型降雨的响应规律。方法以黄土高原南部桥山林区为研究对象，通过对典型林分(阔叶纯林和针阔混交林)不同土层深度土壤水分和降雨的监测，探究不同植被覆盖和坡位条件下的各层土壤水分体积分数对典型降雨的响应特征。结果1) 研究期，降雨量主要集中在8月、9月、10月，其中9月的降雨量最大为251.7 mm。各样点同一土层的土壤水分体积分数季节性差异显著(p≤0.05 ...
