数字滑坡技术及其应用

“数字滑坡”技术，就是以遥感（RS）和空间定位方法为主，结合其他勘探、试验、调查手段获取数字形式的、与地理坐标配准的滑坡基本信息；并利用GIS技术存贮和管理这些数字信息；在此基础上，根据滑坡地学原理进行空间分析，研制各类模型，并服务于滑坡调查、监测、研究、滑坡灾害评价、危险预测、灾情评估、滑坡防治等。通过金龙山三维数字模型，卫星监测易贡滑坡、三峡库区重点城镇滑坡及千将坪滑坡等地的遥感调查说明数字滑坡技术的实际应用。

Progress and Applications for Digital Landslide

The essence of digital landslide technique is to capture basic landside information through remote sensing (RS) and spatial positioning combined with other survey methods; and by using GIS technique to manage and store the digital information; and then based on the landslide geo principium to make spatial analysis and establish digital three dimensional, geo referenced and multi elements thematic landslide model serving the landslide survey, monitoring, assessment and disaster prediction and so on. This paper introduces the application for digital landslide technique through 4 examples: ① three dimensional landslide models for Jinlong Mountain;②satellite monitoring Yigong Landslide;③study for landslides in key towns of the Three Gorges;④Qianjiangpin Landslide
