基于气象站监测数据的特高压输变电工程水土流失监测

Monitoring of soil and water loss in UHV power transmission and transfer project based on meteorological station monitoring data

特高压输电线路工程建设过程会影响地表生态结构,对线路沿线植被、地貌等造成明显影响,进一步加重了水土流失。随着环境保护意识的提高,特高压工程建设越来越需要考虑水土流失监测。提出一种水土流失监测方法,使用气象站来监测输电线路周围地区的气象变化。通过对监测数据分析来确定水土流失情况,为输电线路沿线地表环境恢复和保护提供数据支撑。相较传统的人工监测方式,所提出的监测方法可以大大提高监测精度和效率,并且节省了财力、物力。实际应用于陕西—湖北±800 kV特高压直流输电工程的水土流失监测,效果显著。

The construction of UHV transmission line project will affect the surface ecological structure, significantly affect the vegetation and landform along the line, and further aggravate the water and soil loss.With the improvement of environmental protection awareness, it is more and more necessary to consider soil erosion monitoring in UHV project construction.In this paper, a soil erosion detection method is proposed, which uses the meteorological station to monitor the meteorological changes around the transmission line.The water and soil loss is determined through the analysis of monitoring data, so as to provide data support for the restoration and protection of surface environment along the transmission line.Compared with the traditional manual detection method, the detection method proposed in this paper can greatly improve the monitoring accuracy and efficiency, and save financial and material resources.The method proposed in this paper has been applied to soil and water loss monitoring of Shaanxi Hubei ± 800 kV HVDC transmission project, and the effect is remarkable.
