北京地区的湿地资源对保持区内水资源和生物多样性有重要作用.但因其为小型内陆型湿地,未引起足够重视.文中以TM/ETM+和IKONOS遥感影像为主要数据源,采用遥感融合技术,结合野外湿地环境调查,对区内不同类型湿地进行监测和分析.研究后发现,北京地区主要以河流湿地、水库湖泊湿地和城市公园湿地为主.近几年来,总面积减少一半以上.同时,湿地的生态环境趋于恶化.在此基础上,分析了区内湿地变化的驱动因子,并提出相应的保护与利用措施,为今后湿地保护与恢复提供参考依据.
Wetland resources in Beijing have played an important role in maintaining water resources and biodiversity in the area, but not enough attention has been paid to them because they are small inland wetlands.Taking TM / ETM + and IKONOS remote sensing images as the main data sources, remote sensing Integration technology, combined with field wetland environmental survey, to monitor and analyze the different types of wetlands in the region after the study found that Beijing mainly wetlands rivers and lakes, reservoir wetlands and wetland park mainly in recent years, the total area by more than half At the same time, the ecological environment of wetland tended to deteriorate.On this basis, the driving factors of wetland change in the region were analyzed and corresponding measures of protection and utilization were put forward to provide references for the future wetland conservation and restoration.
