Investigation of Land Erosion Model of Houzhaihe Catchmentin Puding, Guizhou and Its Application
In typical karst area, the problems of water and soil loss are by far serious, for weak natural conditions and man_made adverse effect (breaking down for forest and reclaiming heath). With the stride development of RS (Remote Sensing) and the use of computers techniques, especially the swift development and universal application of GIS, the study of the water and soil loss has been made from quality to quantum that refer to erosion type, classification, morphology and module, as well as study of underlying hazard. In this article, Houzhaihe karst catchment of Puding has been selected as the test site in this study, based on predecessor's works, the quantitative model suitable to karst catchment have been established by RS and GIS techniques. With the support of the PAMAPGIS technology and RS information, the factors of water soil loss are automatically attained in GIS, thereby the actual and latent maps of water and soil loss has been made.
