摘　　要：为了进一步查清大庆湿地资源的类型、面积、分布现状及湿地资源的动态变化情况,采用遥感解译与野外实地调查相结合,应用法国2007年SPOT5影像和美国Landsat TM5影像数据相结合、现状调查与历史资料分析相结合等手段和方法,以生态学为基础,对遥感卫星影像进行处理,获得所需年份大庆湿地数据,建立动态度模型,简述了大庆湿地近20年来的演化特征及原因。得出人为因子是威胁湿地的主要因子,从而为有效地保护大庆湿地生态系统及其环境功能,可持续性地管理和合理利用湿地资源提供科学依据。Some methods like combining remote sensing interpretation with field investigation,combining SPOT5 image data in France in 2007 with TM5 image data in America,and combining investigation of present situation with analysis of historical data,were used to further investigate the types,areas,distribution status and dynamic changes of the wetland resources in Daqing.The image of remote sensing satellite was disposed based on ecology,then the data of Daqing wetland in the years needed were obtained.From this,models of dynamic degree were established and the reasons and characteristics of evolution of Daqing wetland in recent 20 years were described briefly.Besides,human interference was found to be the main factor to threat the wetland.It could provide certain scientific basis for effective protection of the ecosystem and its environmental function in Daqing wetland,and also for sustainable management and reasonable use of the wetland resources.
