摘要
利用无人机航空三维倾斜摄影技术获取熊耳山—伏牛山矿集区重点区段矿山的高精度数字高程模型(DEM)、数字正射影像图(DOM)、数字线划地图(DLG)和数字栅格地图(DRG),并进行数据处理和三维建模。得到的三维模型包含丰富的矿山信息,可以有效便捷地识别提取因矿山活动引发的土地资源损毁、挖损、占压、地形地貌景观破坏及崩塌、滑坡、泥石流、地面塌陷、地裂缝等地质灾害信息,并进行防治与监测工作。对调查区内林地、草地、湿地等空间分布、类型及范围监测,进行植被覆盖率计算。通过对坡高、坡度、坡向及边坡质地分析,为边坡林草地生态修复提供基础数据支持。
High-precision digital elevation model(DEM),digital orthophoto map(DOM),digital line graphic(DLG)and digital raster graphic(DRG)of the key section mine at ore concentration area in Bears Ears-Funiu mountain were obtained using the aerial oblique photography technology by UAV,and the data processing and 3D modeling were carried out.The obtained three-dimensional model contains rich mine information,which can effectively and conveniently identify and extract the geological disaster information such as land resource damage,excavation loss,occupancy,topographic and landform landscape damage and collapse,landslide,mudslide,ground collapse as well as ground cracks caused by mining activities,and carry out prevention and monitoring work.The spatial distribution,type and extent of woodland,grassland and wetland in the survey area were monitored,and the vegetation coverage rate was calculated.Through the analysis of slope height,slope,aspect and slope texture,basic data support is provided for the ecological restoration of slope forest and grassland.
