摘  要:
The authors analysed and explored the theory,technology and method of construction of digital watershed,which integrated the result of research group, including high resolution remote sensing data settlement model,watershed special database,etc.According to analysis on user needs and the development of computer software and hardware,the evolution of digital watershed can be divided into three stages:initial stage,middle stage and high stage,which is a gradual and ameliorative processing.
