中文摘要	采用3S技术对2012年宁夏旱区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,实地调查了宁夏湿地典型植被,获取了较为全面、完整和系统的宁夏湿地资源数据,在此基础上研究了不同湿地类型碳汇功能。结果表明:宁夏湿地总面积为19.65万hm~2,占国土面积的3.1%,位居我国西部干旱半干旱地区之首。其中自然湿地面积(包括河流湿地、湖泊湿地、沼泽湿地)为17.03万hm~2,占宁夏湿地面积的82.38%,主要分布在宁夏沿黄经济区。宁夏湿地总碳储量为1502.80万t,约占宁夏旱区五种主要生态系统(林地、灌木、草地、湿地、特色经果林)碳汇的45.03%,比全球湿地总碳储量占全球陆地生态系统碳库的百分比(10%-35%)高出10多个百分点。预测了2015年的碳汇潜力为1593.48万t,与2012年相比,2015年湿地面积增加0.34万hm~2,碳汇量增加90.68万t。
英文摘要	Integrated techniques of 3S were used to translate the Landsat TM artificial satellite remote senseportrait of Ningxia arid land,and field sites were investigated by GPS,by which the completed wetland resource information were acquired. Also the typical vegetation of wetland in Ningxia were investigated 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 Ningxia was 19. 65 * 104hm~2,accounting for total land area of 3. 1%, ranking the first among the western arid and semi arid regions. The natural wetland area (including river wetland, lake wetland,wetland) was 17. 03 * 104 hm~2,accounting for 82. 38% of the total,they are located mainly along the Yellow River economic zone. The wetland carbon reserves was of 1502. 80 * 10~4T,accounting for 45. 03% of the carbon sequestration of the five major ecosystems (woodland,shrub,grasslands,wetlands,and features fruit trees) in Ningxia arid areas,it was 10 percentage points more higher than the percentage of the global total wetland carbon reserves of the global terrestrial ecosystem carbon pools (10%-35%). Predicted carbon reserves of 2015 is 1593. 48 * 10~4 T. Compared with 2012,wetland area will increase 0. 34 * 10~4hm~2 in 2015, carbon sequestration increase 90. 68 * 10~4T.
