Soil Mass Movement (landslip)

Mass movement (landslip) occurs on sloping ground where large slabs of the ground surface slide downhill. Mapping shows the extent of, or potential for, landslip, while detailed proportion data are supplied for calculating total land areas affected by, or with potential for, mass movement (spatial data statistics).

块体运动 (Mass movement)，又称滑坡 (Landslip)，发生于坡地之上，此时地表的大块岩土体沿坡向下滑移。相关测绘成果可展示滑坡的现有分布范围及潜在发生区域，同时配套提供了详细的占比统计数据，用于核算受块体运动影响或存在块体运动发生潜力的土地总面积（空间数据统计）。
