Abstract

With the high-density construction of coastal power grid, Soil Erosion (SE) in subtropical coastal mountainous area is seriously concerned. Based on the Revised Universal Soil Loss Equation (RUSLE) with Sentinel-2 image, taking the Fujian-Tangyuan Electric Transmission Line (ETL) as the study case, designing the 'region-line-point ' study area, and making the SE disturbance formula, the paper discusses the seasonal variation and spatial pattern of soil erosion generated from ETL. 1) The seasonal variation (2018-2020) of SE in the study region is apparently characterized as that SE in spring varies greatly (0.83 ～ 4.21t/hm² ∙a), and that in summer (1.42～3.05t/hm² ∙a) is heavy, and that in autumn and winter (0.79～0.94t/hm² ∙a) is weak. The slight erosion class occupied more than 82.91% of the study area. 2) The construction of the ETL impresses greater impact on the average SE density and the area proportion of the slight erosion class in the “point” zone than those in “region or line”. 3)The SE disturbance impacts of the ETL on the “point” zone in spring and summer are 3.43 and 2.71t/hm² ·a respectively. 4) The spatial pattern of the SE disturbance caused by ETL is characterized by the point-dispersion-pattern, non-line pattern and non-region pattern. The research results provide the detailed temporal-spatial boundaries for SE assessment and controlling measurement during ETL building.
