摘　　要：以黄骅湿地为例,通过对湿地信息源分类和解译标志的建立,利用GIS和RS技术进行湿地信息提取,以实现湿地类型分布和湿地面积的调查。结果表明,黄骅湿地总面积10 138.6 hm2,其中河流湿地650.1 hm2,库塘湿地3 436.5 hm2,沼泽湿地1 737.2 hm2,沿海滩涂湿地247.5 hm2,虾池2 422.9 hm2,盐田1 644.4 hm2,湿地人工化程度严重,应加强措施对天然湿地进行保护。The study on Huanghua Wetland was based on the Geographic Information Systems（GIS） technology and Remote Sensing（RS）,and through the information retrieval results, the wetland resource including the classification and surface area calculation was investigated. The result indicated that total areas of wetland was 10 138.6 hm^2 ,and the area of river wetland was 650.1 hm^2,reservoir wetland was 3 436.5 hm^2 ,smash wetland was 1 737.2 hm^2,coast wetland was 2 47.5 hm^2,shri,np factory was 2 422.9 hm^2 and the salt factory was 1644.4 hm^2.The artificial wetland was increased notably and wetland must be protecteat.
