| 摘 要： | 卫星遥感技术应用在高压输电选线中, 具有常规方法无法比拟的优势。在西北-华北500 KV高压直流输电线路工程的宁-蒙-陕段的选线研究中, 通过对多时相遥感数据处理, 获取了研究区内的地质、地貌等相关信息, 并分析了沿线沙地的动态演化及分布规律。研究结果表明, 区域沙丘属于半固定沙丘, 移动速度缓慢, 全区的沙化地总体表现为负增长。尤其是基于地形图等高线要素获取数字高程模型(DEM ) , 对研究区进行三维虚拟地理景观可视化模拟, 并利用相应的遥感图像进行叠加复合, 获取真实三维地表景观, 提高可视化效果。在此基础上通过综合分析区内地形、地貌、工程地质、岩性构造、地理条件及居民地分布等相关因素, 提出了两套选线方案作对比分析, 为高压输电线选线方案的最终确立提供了科学依据。

| Abstract: | Satellite remote sensing technology applied in the route selection of the high voltage transmission lines has the advantage that the normal method can't compare to.In the study of the route selection engineering of the 500 kV high voltage direct current transmission lines in Ning-Meng-Shan subsection of northwest-north China,we acquired the relative information of geology,physiognomy and so on in the research district,and analyzed temporal evolution and distribution rule of sand dune and desertification along the route,according to processing multi-temporal images.The result suggests that the sand dune is characterized by semi-active dune,the move speed is very slow,and all round the district desertification shows negative increase.Especially we acquired the digital elevation model based on the contour element of the map and visually simulated dummy three-dimensional geography sight in the study area,also we obtained real three-dimensional surface sight by attaching and compounding the relative remote sensing image,which improved the visual impact.The article proposes two schemes of routing selection according to synthetically analyze landform,physiognomy,engineering geology,lithology,structure,geographical condition,the distributing of habitation and correlative factors based on the results of the processing which mentioned above.It provides the scientific ground for ultimately establishment of the scheme for routing selection on the high voltage transmission lines. |
