A Depth Analysis Algorithm for Characterizing the Regional Evolution of Soil Erosion for Power Transmission Projects in Alpine Regions

Conventional soil erosion analysis algorithms are mainly based on hydrological simulation, which is affected by climate, geomorphology and other evolutionary factors, and the analysis results are not comprehensive, affecting the construction quality of power transmission and transformation projects. Therefore, the depth analysis algorithm of regional evolution characteristics of soil erosion for transmission and substation projects in alpine areas is designed. It analyzes the landscape pattern of soil erosion in transmission and substation projects in alpine area, obtains the information of spatial distribution, area and intensity of soil erosion in the project area, and analyzes the landscape pattern parameters such as fragmentation degree, fractal dimension and patch shape index of soil erosion landscape. We analyze the dominant factors in depth in relation to the evolution characteristics of soil erosion areas, taking climate factors, geological and geomorphological factors, vegetation cover factors, and human activity factors into consideration, so as to reveal the intrinsic mechanism of the regional evolution of soil erosion. Comparative experiments were conducted to verify that the algorithm has higher analyzing accuracy and can be applied in real life.
