摘　　要：采用RS、GIS和GPS技术对2008年济南市TM卫星假彩色数字影像进行解译,并利用GPS仪进行了野外考察验证,现场调查了济南市湿地生物多样性,获取了较为全面、完整和系统的济南市湿地资源信息,建立了全市湿地资源数据库并进行了济南市不同湿地类型碳汇功能的初步研究。结果表明,济南市湿地总面积为327.6 km2,其中天然湿地面积为258.3 km2,占济南市湿地面积的78.85%,济南市湿地面积比全国、山东省湿地面积分别高出0.4%、3.1%,主要分布在济南境内的黄河两岸和商河等区县;济南市湿地总碳储量为747万t,约占济南市整个生态系统碳汇的8.9%,与全球湿地总碳储量的比例基本相当,2008年碳增量为32万t,其中沼泽湿地碳储量和碳增量均最大,分别为541万t和27万t,分别占济南市湿地资源的84.4%和72.4%。Integrated techniques of RS, GIS and GPS were used to translate Landsat TM artificial satellite remote sense portrait of Jinan City, Shandong Province and field sites were investigated by GPS, by which the completed wetland resource information were acquired. Also the biodiversities of wetland resource in Jinan were investigated, based on which to establish the wetland resource database. Carbon sequestration of different wetlands was estimated and their function was analyzed. Results showed that total area of wetland of Jinan was 327.6 km2, including natural wetland area 258.3 km^2 accounting for total wetland area of 78.85%, which was 0.4% and 3.1% bigger than wetland area of the whole Chinese average and Shandong Province. The wetlands mainly locate at both banks of Jinan section of Yellow River and Shanghe. Total carbon sequestration of wetland in Jinan was 7.47million tons, accounting for 8.9% of the whole city ecosystem carbon sequestration and roughly equivalent to the whole world wetland total carbon sequestration. Carbon sequestration increment in 2008 was 0. 32million tons, in which the highest of total carbon sequestration and its increment was separately 5.41million tons and 0. 27million tons in the swamp wetland, accounting for 84.4% and 72.4% of the whole Jinan wet/and.
