基于实地和遥感调查的离子型轻稀土尾砂土壤侵蚀对植被修复措施响应
Shuitu Baochi Xuebao, 2020 稀土开采产生大量尾砂，导致严重土壤侵蚀，伴生水质和地质灾害，评价植被修复措施对稀土尾砂土壤侵蚀治理效果可为措施优选提供理论依据。以寻乌县离子型轻稀土尾砂区为研究区，基于1982—2015年GIMMS NDVI 3 g、DEM等遥感和尾砂理化性状现场调查数据，采用空间代时间方法，结合RUSLE模型及其全微分公式探究不同修复年限土壤侵蚀量对植被修复措施的响应机理。结果表明：1982—2015年研究区土壤侵蚀模数显著下降，倾向率为-60 t/（km2·10a），突变年份为2008年；在植被修复措施实施年 ...

Shuitu Baochi Xuebao, 2023 为探究生物结皮发育驱动下土壤水蚀特征及机理,选取苔藓发育为优势种的退耕样地,设计5个盖度等级(1%~20%,20%~40%,40%~60%,60%~80%,80%~100%),以裸地为对照,在不同水流剪切力(6.12~19.64 Pa)下进行冲刷试验。结果表明:结皮发育显著影响土壤养分含量,且高盖度结皮覆盖下养分表聚效应更加明显。生物结皮发育显著影响土壤分离能力,裸地土壤分离能力为生物结皮的3.58~348.95倍,裸地细沟可蚀性(0.293 5 s/m)为生物结皮(0.001 0~0.082 2 s ...
