Study on Influencing Factors of Soil Erosion in Waqie Town Based on InSAR Technology
摘要
Abstract
To support ecological governance and protection in the source region of the Yellow River,this study takes Waqie Town as the research area.InSAR technology was used to extract a DEM with stronger timeliness,higher accuracy,and higher resolution,and then to derive terrain factors that better reflect actual local conditions.Based on the RUSLE model,soil erosion modulus in Waqie Town from 2019 to 2023 was calculated.SPSS analysis shows that the influencing factors of soil erosion in Waqie Town can be ranked as R>P>L>C>S.Among them,the rainfall erosivity factor had the highest VIP value of 1.704 among all potential factors,with r=1,showing a perfect positive correlation and acting as the core driving factor;therefore,its influence should be reduced through corresponding drainage measures.The soil and water conservation practice factor maintained a VIP value above 1.3,with r=-0.9,showing a significant negative correlation and serving as the core inhibiting factor,which indicates that relevant engineering measures have a remarkable effect on suppressing soil erosion.The slope length factor L had a significantly negative regression coefficient of-12.33 and was identified as a secondary dominant control factor.The vegetation cover and crop management factor C,the slope factor S,and the soil erodibility factor K were secondary auxiliary factors.关键词
