摘要(Abstract)：

易发性评价是区域滑坡灾害风险预警与稳定性分析的基础，针对乡镇尺度的大比例尺精细化滑坡易发性评价，传统基于水文学和地貌学的斜坡单元划分方法难以满足评价精度。针对以上问题，以重庆市万州区大周镇为实例验证对象，形成了适用于精细化评价的改进斜坡单元划分方法。首先从斜坡地质环境孕灾规律出发，综合考虑地形地貌、物质组成、斜坡结构和灾害类型的均一性要求，提出了基于斜坡地质环境一致性的改进斜坡单元划分方法，选择重庆市万州区大周镇为实例验证对象，并与水文分析法、曲率分水岭法进行了对比分析。结果表明：(1)改进斜坡单元法划分的评价单元大小均匀性较好，未出现细碎单元或畸形长条状单元；(2)评价单元的总体形态特征更为合理，形态指数集中在1～2之间，呈现圆形或正方形斜坡形态；(3)改进斜坡单元划分的结果与已有灾害边界范围的叠加重合度最高，能更好地体现滑坡易发性评价或稳定性分析物理意义。研究结论对提高区域滑坡易发性评价的准确性与精度具有重要借鉴意义。
