Spatiotemporal differentiation of terrace-to-slope conversion in Rongcheng City and its impacts on soil erosion
摘要
Abstract
[Objective]This study explores the spatiotemporal distribution characteristics of terrace-to-slope conversion patches in hilly areas and analyzes their impacts on soil erosion and major influencing factors,thereby providing a theoretical basis for the coordinated development of agricultural modernization and ecological economy.[Methods]Rongcheng City in the hilly region of the Jiaodong Peninsula was selected as the study area.Based on high-resolution remote sensing images,1:10 000 digital topographic maps,and multi-year field survey data,the geographical center of gravity model was applied to investigate the distribution of terrace-to-slope conversion patches from 2014 to 2024.The Chinese Soil Loss Equation(CSLE)and the geodetector method were then used to analyze the variations in soil erosion and its driving factors after terrace-to-slope conversion.[Results](1)From 2014 to 2024,the total area of terrace-to-slope conversion in the study area reached 1 468.91 hm².This process 62.51％.However,erosion levels remained higher than those before conversion.(3)Slope gradient,vegetation cover,and per capita economic forest area in rural areas showed the strongest explanatory power for soil erosion after terrace-to-slope conversion,with q-values of 0.38,0.24,and 0.139,respectively.Moreover,the interaction between slope gradient and vegetation cover exhibited the highest explanatory power,with a q-value of 0.725.[Conclusion]In the hilly region of the Jiaodong Peninsula,soil erosion tends to stabilize in the fifth year after terrace-to-slope conversion.However,influenced by factors such as slope gradient,vegetation cover,and human activities,soil erosion levels still differ from the original state before conversion.Therefore,during the implementation of terrace-to-slope conversion,it is necessary to further optimize the integrated design of topography,waterways,production roads,and soil and water conservation measures from both ecological and economic perspectives,so as to achieve precise management and long-term ecological protection.关键词
