Watershed, as geography unit with specific boundaries, is a compound ecosystem, within which aii components are inextricabiy iinked by water. These components interact with one eiement responding to the action or change of another. Nowadays, integrated watershed management has been regarded as an efficiency approach of soiving the confiicts between resources utiiization and environment protection. However, Integrated Watershed Management need deai with iots of muitidiscipiinary probiem, intergovernmentai harmony issues. There are no mature theory and actabie methods, so the integrated watershed management oniy iimited to a perfect goais. This paper, based on the research and experience review about watershed management, discusses the technoiogy integrated watershed management. The integrated watershed management can be performed by five steps, i.e. (1)To confirm the watershed probiem and coiiecting the information about it;(2)To anaiyze and assess the watershed process;(3)To make integrated anaiysis and assessment;(4)To make out the watershed pian;and (5)To actuaiize the watershed pian and make some adjustment according to the reaiity. In integrated watershed anaiysis and management, it is the key technoiogy to deveiop watershed information and integrated modei. Stiii, there are some important watershed eiements information can't be acguired efficientiy, inciuding runoff, water guaiity, soii water and so on. In China, Some watershed database in iarge scaie need be deveioped and effective share reguiations need be make out. In watershed simuiation technoiogy, the probiems about integration between GIS and watershed process modei, different discipiined modeis and professionai modei visuaiization need be soived.
