Abstract—3S technology is the effective method to carry out
the dynamic monitoring of soil and water erosion. The paper
select XiangXi watershed as the study region. Firstly, extracting
erosion factors like vegetation coverage, land-use types and slop
information, then conducting spatial overlay analysis to extract
distribution of soil erosion intensity. Finally, analysing the
change tendency by using transfer matrix to provide basic data
for soil and water conservation. Results suggested that the
intensity of soil erosion was getting better from 2016 to 2017, the
Micro-degree and Slight-degree were slightly increased, the
Medium-degree and Dought-degree were slightly reduced, the
Extrem-degree and Vigorous-degree were alleviated.
Index Terms—Soil and water erosion, dynamic monitoring, 3S technology, transfer matrix.
