Soil erosion is t he first and most important problem to a highway construction project.Usually

highway construction units do riot carry out soil and water conversion supervision

so implementing the supervision is very essential to highway engineering.Meanwhile it is proved to be feasible from theory or prac- tice.The program of implementing soil and water conversion supervision in highway engineering should in- elude establishing standards and regulations

deciding operation model

drawing up operation program

mak- ing management ways and working systems

and determining the major contents of supervision.
