贵州2010年6月28日关岭滑坡遥感应急调查

2010年6月28日，贵州省关岭县发生大规模滑坡，2010年6月30日中国国土资源航空物探遥感中心根据国土资源部中国地质调查局的部署，紧急派机飞往灾区进行航摄，获取了灾后第3天的高分辨率航摄图像数据，经正射处理后，进行解译提供灾区使用。该解译以QuickBird数据、航摄数据及1∶50 000数字地形、航摄立体像对生成的DEM分别作为滑坡前后的遥感数据源及地理控制数据源。采用数字滑坡技术估算了628关岭滑坡灾害的灾损，解译了滑坡的形态结构及运动方式，利用滑坡前后DEM计算了原斜坡滑走及堆积的滑坡方量，分析了628关岭滑坡成因及存在的地质灾害隐患，并提出防治措施建议。

Remote sensing interpretation on June 28,2010 Guanling landslide,Guizhou Province,China

On June 28,2010,a large-scale landslide occurred in the county of Guanling,Guizhou Province.On June 30,China Aero Geophysical Survey & Remote Sensing Center for Land and Resources(AGRS) carried out the urgent remote sensing flight disposed by China Geological Survey Administration,and high-resolution aerial image data of three days after landslide was captured.Then,ortho-rectification was completed for disaster interpretation and analysis.QuickBird data,aerial photo,1∶50 000 digital topographic data and DEM were taken as pre-and post-6.28 landslide remote sensing data and geographical control data respectively.Disaster loss assessment and landslide morphological structure and movement properties were interpreted by using digital landslide technology.Landslide volume was estimated by using the DEM calculation of pre-and post-landslide.Based on the analysis of formation factors of 6.28 landslide and hidden geo-hazard interpretation,suggestions are proposed for disaster prevention and mitigation.
