卫星遥感和地理信息系统在湿地资源调查中的应用

A study on the methodology of investigation of the wetland resources by using satellite remote sensing and geographic information system

以若尔盖高原为调查研究区，湿地资源（沼泽、泥炭）为调查研究对象，通过地貌区划、湿地资源分类系统、图象处理与机助解译分类、目视解译景观综合分析判读、遥感制图等方面的应用研究，完成了研究区 １： １０万湿地资源现状调查，建立了湿地资源信息管理系统，较系统地确定了采用卫星遥感、地理信息系统和地面调查相结合的技术手段开展湿地资源宏观调查的应用方法。

This paper discusses the methodolgy of the wetland resources investigation by using Landsat data and Geographic Information System technology. The technical procedures have been established, which include geomorphologic divisions, ciassification system of wetland (swamp land and peat), image processing and image intepretation by using computer. The survey of the present situation of wetland resources on Ruoergai Plateau in Sichuan province on the scale of 1: 100000 has been completed. The application of the methodology results in an attributcd database and an information system of wetland resources.
