摘　　要：对古浪县第二次全国湿地资源调查的技术、结果进行了系统分析,探索了研究区内湿地资源调查更新的方法,通过"天空地"协同和"互联网+"的调查更新技术全面更新研究区内湿地资源调查数据库,以全面掌握湿地资源状况。研究结果:1)古浪县第二次湿地资源调查范围内的非湿地类型面积达4 615.35 hm2,占全县第二次湿地调查总面积的59.31%。2)变更后县域内湿地资源总面积4 131.54 hm2,以河流水面、内陆滩涂、水库水面、沟渠为主要用地类型,较第二次调查湿地面积净减少3 650.25 hm2。3)"天空地"协同遥感监测技术为湿地资源变更监测提供高精度多源数据,保证了调查、监测的精度和准确性。This study is to comprehensively analyze the technology and investigation result of the Second National Wetland Investigation about Gulang Province,and to research new technology about wetland investigation and updating.The research updates Gulang wetland investigation database by aerial remote sensing technique combined with internet-Investigation technique,and gains latest survey data of wetland around Gulang countywide.The research finds that:1)these is about 4 615.35 hm^2 non-wetland still retained in the boundaries of wetland,and the proportion of non-wetland is about 59.31%.2)the latest survey data of Gulang wetland is 4 131.54 hm^2,and the main land use type are inland river,tidal flats,reservoir,and man-made canal.By comparison,the latest wetland area is 3 650.25 hm^2 less than the Second National Wetland Investigation data.3)the aerial remote sensing technique based on different sensor can supply high accuracy positioning,high time resolution,high spatial resolution images for wetland investigating and updating,all of those will ensure the accuracy of wetland investigation and research.
