基于分层多尺度分割的水土流失图斑落地方法研究
Extraction method of soil erosion vector based on layered multiscale segmentation
摘要
Abstract
Through combining requirements of soil erosion control work with the grid results of soil erosion,the accurate identifi-cation,positioning,and cutting of soil erosion vector suitable for control could be achieved,which is helpful to promoting applica-tion of dynamic monitoring of soil and water erosion.We take Lingchuan County,Guilin City as the research area,propose a meth-od of extracting soil erosion vector based on layered multiscale segmentation,and accurately identify soil erosion vectors in the re-search area.The results show that the layered multiscale segmentation method achieves a good balance between soil erosion grid results and land use vectors,the accuracy of soil erosion vector based on layered multiscale segmentation method reaches 90％,and has advantages such as accuracy,efficiency,and easy application compared to traditional methods.The extracted vectors can directly support the subsequent soil erosion control work.The research results can provide basic data and decision-making refer-ences for improving the quality and efficiency of comprehensive management of Lijiang River Watershed,and also provide method-ological references for the implementation of extracting soil erosion vectors nationwide.关键词
