地理信息系统(GIS)在非点源污染控制中的应用

Application of GIS in the Control of Nonpoint-Source(NPS)Pollution

GIS技术是一种兼容、存储、管理、分析、显示和应用地理信息的计算机系统 ,具有强大的空间分析功能 ,把它用非点源 (NPS)污染的分析已经成为一种切实可行的方法。国外在该领域通过十几年的研究 ,取得了一些经验和成果 ,这对我国在该领域的研究是一种有益的启示。本文阐述了非点源污染与 GIS技术的特点及二者结合应用过程中应该注意的要点 。

GIS is an information system with powerful spatial analyzing capability.It can compatible、storage、manage、analyze、display and apply geographic spatial information.It has been regarded as a feasible method to apply GIS in NPS pollution control plan.There are many researches on combining GIS with NPS pollution models in the developed countries.All these progress and experience can be a valuable inspiration to our research.The feaures and essentials of NPS pollution and GIS was discussed in this paper.A few examples were illustrated at the end of the paper.
