This article takes The Riparian Ecosystem Management Model (REMM) as an example, introduced the newest achievement of riparian zone abroad. REMM is a computer simulation model; it is used to simulate hydrology, nitrogen (N), phosphorus (P), and carbon (C) cycling and transport and plant growth for riparian zone. Inputs to REMM are the water, sediment, nitrogen, and phosphorus loadings in surface runoff and subsurface flow from a field. Outputs from REMM are the water, sediment, nitrogen, and phosphorus in surface runoff, subsurface flow, and seepage to a stream or adjacent aquatic ecosystem .The riparian buffer consisted of three zones; REMM allows the user to define vegetation types for each zone in order to let the user to investigate which vegetation buffer is more efficiency. Output from REMM will allow designers to develop buffer systems to help control non-point source pollution. Analyzed and appraised to REMM model finally.
