摘要
湿地是一种重要的土地资源,也是人类生产、生活资料的重要源泉。利用GIS、RS、GPS技术研究湿地资源具有重要意义。安庆湿地由龙感湖、黄大湖、泊湖、菜子湖等组成。该区生物多样性和物种稀有性方面有其独特的意义,对研究人为活动影响下,湖泊湿地的发展变化及恢复有重要作用。建立湿地信息系统,为加强安庆湿地资源的开发利用和规划管理提供决策服务。
Wetland is not only an important land resource but also a source of human production and living materials utilize wetland resources. It is of great significance to the utilization of GIS, RS and GPS technology on the whole, to study how to scientifically manage and rationally use wetlands. The wetland in Anqing is distributed in the north bank of the Yangtze River, the largest in distribution in Ahhui province. It covers an area of 9.87×104hm2 being mainly composed of four lakes. It has invaluable function to conserve biological diversity and scarce species. At the same time, it is also a typical region to study the development and restoration of the lake wetland under the influence of human activities. Anqing wetland information system has two kinds of structure, one is logical, the other is functional. Database is the core, which is comprised of attribute data and special data. Information of the system comes from on-the-spot survey, statistical datum and remote sensing image and so on. In this paper, the structure of the system, design principle and function are preliminarily discussed in order to provide a new method for Anqing wetland research and management.
