特高压输变电工程具有线路路径长、扰动区域分散等特点。其线路施工道路区是水土流失防治分区之一,监督管理相对困难。为了快速准确监测特高压输变电工程线路施工道路扰动,精细管控水土流失问题,开展智能化的水土保持监测研究十分必要。本文以锡盟-胜利1000kV特高压交流输变电工程为研究对象,利用差分主成分分析法快速准确识别出施工道路,从而监测其扰动。经现场验证,差分主成分分析法提取效果与目视遥感解译的效果基本一致。该方法可以为特高压输变电工程线路施工道路水土保持监测工作提供技术支撑。
UHV (Ultra-High Voltage) transmission and transformation engineering always has long lines and scattered disturbance area. As one of the water and soil conservation area, construction roads of UHV transmission and transformation are difficult to supervise. In order to get better control of water and soil conservation, research on intelligent monitoring methods of construction roads is urgently needed. In this paper, the Ximeng~Shengli UHV Power Transmission and Transformation Project Area is used as the research area. The differential principal component analysis method is used to automatically identify the UHV construction road. The algorithm can quickly and accurately identify the construction road through multiple experiments. The results show that the extraction effect of differential principal component analysis is basically consistent with the effect of visual remote sensing interpretation. The method can provide technical support for the monitoring work of UHV power transmission and transformation engineering.
