Shuitu Baochi Xuebao, 2006 在贵阳市乌当区采集了9种母质（岩）上发育的土壤样品763个，分别测定了土壤的主要理化性质和主要重金属元素含量，通过对比分析表明不同母质（岩）发育的土壤理化性质和重金属含量都具有很大的差异。土壤理化性质的差异性主要表现为：石灰岩、红色粘土、老风化壳和页岩发育的土壤质地粘重。砂岩发育的土壤质地较轻，钙质紫色砂页岩、白云岩、砂页岩和河流冲积物发育的土壤质地适中；石灰岩、白云岩和钙质紫色砂页岩发育的土壤pH值为中性至微碱性。河流冲积物发育的土壤pH值为中性，其余5种母质（岩）发育的土壤pH值为酸性至强酸性 ...

Wildlife Letters, Volume 4, Issue 1, Page 23-31, March 2026.American badgers, a medium‐sized carnivore occurring in much of North America, are important predators in prairie landscapes though our understanding of their habitat use requirements in these areas is unclear. We used a multi‐scale approach to understand American badger habitat use at both local and landscape scales.

World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Shuitu Baochi Xuebao, 2002 土壤质量是现代土壤学研究的前沿领域，它不仅注重土壤在生态系统内支撑生物生产力、保持环境质量的功能，而且还强调食物安全和动植物的健康。近年来，土壤质量问题为国内外土壤学研究的热点，就土壤质量的概念、评价指标、土壤质量与生产力、土壤质量与环境质量及动物、人类健康等方面进行了研究及报导。土壤质量物理指标是土壤最基本的质量指标，土壤结构是土壤质量物理指标重要内容，他控制了生态系统内的许多功能，特别是在黄土高原地区，土壤为化学物质成分均一且抗侵蚀较弱的黄土，土壤结构特性决定了该区土壤质量的主要功能 ...
