河岸带生态系统管理模型研究进展

Research Progress on Riparian Ecosystem Management Model

以河岸带生态系统管理模型REMM为例,介绍了国外河岸带研究的最新成果。河岸带生态系统管理模型(REMM)是一种计算机模拟模型,它可以模拟河岸带的水文、C、N、P营养物质循环、迁移及植被的生长过程。REMM输入的数据是田间的N、P等营养物质、沉积物,输出的是地表径流和浅地表径流及通过渗漏转移溪流和周围水体中的营养物质、沉积物的数量。河岸带包括三个区,REMM允许用户定义每一个区域的不同植被类型组合,以便找出拦截污染物效果较好的缓冲带类型,模型的模拟数据可以为建立植物缓冲带,提供决策依据。最后对REMM模型进行了分析与评价。

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.
