基于GIS的凤嘴江水污染控制规划数据库研究

Research on Data Base of GIS based Water Pollution Control Planning System for Fengzui River

地理信息系统 (GIS)是 2 0世纪 6 0年代兴起的新技术 ,将它应用于水污染控制规划 (WPCP)是一个新的研究领域 ,其中数据库技术是整个系统的基础和信息源 ,也是系统发展的瓶颈技术之一 ,有必要进行深入和全面的研究。由于水污染控制规划系统本身的复杂性 ,决定了其所涉及的数据比一般的管理信息系统复杂得多。本研究以 Geo MediaProfessional3.0为基础平台 ,对系统数据库建库过程中涉及的数据特点、数据结构与数据模型、数据组织与管理、数据库功能分析等问题进行了研究 ,开发了基于 GIS技术的凤嘴江水污染控制规划数据库 ,较好地满足了 GIS应用的要求 ,为相关数据库的建设提供了经验。

WT5”BZ]Geographic information system (GIS) is a technology appeared in the 1960s, and its using in water pollution control planning (WPCP) is still a new field on which worthing spending much time to study. As information base, data base is one of the bottle necks related to the system’s application. Because of the complication of WPCP, its data base is also a time consuming and complex technology. In this paper, data base properties、data base model、data organization and management of GIS based WPCP for Fengzui River, Nanchuan City, were studied, and the data base was developed. [WT5”HZ]
