基于2005—2017年中国及周边地区9场地震滑坡制作的全国滑坡危险性
Shuitu Baochi Xuebao目的通过构建随机森林模型，全面评估和预测全国范围内的滑坡危险性，为防灾减灾提供科学依据和决策支持。方法基于9个典型地震区域（如汶川、芦山、鲁甸等）的滑坡样本数据，综合提取滑坡正负样本点，并结合地形、降雨、土地利用、NDVI等多因子数据，利用栅格标准化处理和波段合成技术，构建随机森林模型进行训练与验证。在此基础上，应用模型对全国范围的滑坡危险性进行预测，并通过AUC值等指标评估模型性能，分析关键影响因子及其作用机制。结果1）随机森林模型在多个地震区域均表现出较高的预测性能，AUC值最高接近1 ...

Suitability analysis and recommendations for professional monitoring techniques and methods of landslides in the Three Gorges Reservoir: A case study of the Zigui section in Hubei Province [PDF]
The Three Gorges Reservoir area is one of the earliest regions in China to systematically implement professional monitoring and early warning for geological disasters such as landslides. Since the impoundment of the Three Gorges Reservoir in 2003, nearly

Shuitu Baochi Xuebao, 2020 研究植被对重力侵蚀的作用机理可为黄土高原水土保持规划提供依据。通过对坡度70°、坡高1.5 m的黄土沟坡裸地模型和根土复合模型（简称根土模型）的降雨模拟试验，对比分析暴雨条件下植被对沟坡重力侵蚀的影响。结果表明：植被对沟坡重力侵蚀总量的影响不显著，根土模型5次降雨后次降雨重力侵蚀量平均值仅较裸地模型减小12%。植被能够-定程度上促使沟坡雨后重力侵蚀的增长，根土模型雨后重力侵蚀总量占次降雨重力侵蚀总量的比例为12%，而裸地模型相应的比例仅为1%。沟坡植被对不同类型重力侵蚀的影响差异较大 ...

Shuitu Baochi Xuebao, 2016 “5·12”汶川地震引发了大量的山体滑坡，在降雨径流的冲刷下，造成更加严重的次生灾害。为研究震区滑坡堆积体的壤中流产流特征，采用室内人工降雨装置，对在不同降雨强度（1.0，1.5，2.0 mm/min）和土石比(1︰1，1︰2，1︰4)条件下滑坡堆积体壤中流产流开展人工降雨—产流过程的试验。结果表明：（1）在不同土石比的条件下，壤中流总体趋势体现为在开始阶段增长极快，然后趋于稳定阶段直至降雨停止后，壤中流产流量迅速减小。（2）壤中流累计产流量和降雨时间为线性显著相关（R2为0.946 5～0.999 6）

Shuitu Baochi Xuebao[目的] 经验性降雨阈值存在地域局限性,在黄土高原开展滑坡灾害降雨阈值模型研究具有重要意义。[方法] 以黄土高原延河流域为研究区,综合Sentinel-1A、DEM、GPM降雨等多源数据,首先基于时序InSAR对延河流域进行滑坡识别;然后计算降雨因子与滑坡形变量间的相关性,确定前期降雨天数和前期有效降雨衰减系数;最后计算前期有效降雨量(E)、降雨强度(I)和降雨历时(D),并结合幂函数建立E-D、I-D和E-I降雨阈值模型。[结果] (1)共识别出2017—2021年107个滑坡 ...
