摘要
湿地研究的关键在于定量化获取和分析湿地信息 ,RS和 GIS技术为湿地研究提供了新的方法和技术支持。从湿地资源调查、湿地识别和湿地分类、湿地动态变化监测、湿地制图、湿地与环境因素定量模型、湿地信息系统 6个方面 ,对国内外学者利用 RS和 GIS进行湿地研究的工作进展予以回顾。在此基础上概要说明 RS和 GIS技术在湿地研究中存在的问题及发展前景 ,指出 RS和GIS技术在湿地研究中的应用应从拓宽研究领域和完善技术体系两方面向更高。
The key of wetland research is to obtain and analyze quantitatively wetland info rmation. RS and GIS technology provide a new method for wetland research. In thi s paper the application of RS and GIS technology on wetland research is reviewed from the aspects of the survey of wetland resources, wetland identification and classification, the monitoring of wetland dynamic change, wetland mapping, the quantitative model of wetland and environmental factors, wetland information sys tem. In the meanwhile, the problem and development trend of RS and GIS technolog y on wetland are analyzed. The application of RS and GIS technology on wetland s hould be further developed from broadening the research fields and advancing tec hnology system.
