摘　　要：基于GIS和RS技术,采用动态度、湿地动态变化图谱和质心转移的方法,对1990—2015年扎龙湿地景观的时空动态变化进行分析.结果表明:①扎龙湿地以沼泽湿地为主,占比约为92%;②1990—2015年研究区沼泽湿地和水体的面积均有所增加,水体面积的变化幅度大于沼泽湿地面积的变化幅度,沼泽湿地的质心向西南方向移动,而水体的质心则先向西北后向东北转移;③扎龙湿地面积增加主要受气候变化和人类活动影响.Dynamic degree,wetland atlas,centroid transfer and normalization of ellipses were adopted to analyze the temporal and spatial dynamic changes of Zhalong wetland from 1990 to 2015 based on GIS and RS technology.The results showed that:①The marsh wetland was considered to be the main distribution in Zhalong wetland,accounting for about 92%.②The area of both the marsh wetland and the water body increased somewhat in the study area from 1990 to 2015;the change range of the water body area was greater than that of the marsh wetland;the center of the marsh wetland moved to the southwest,while the center of the water body shifted to the northwest and then to the northeast.③Climate change and human activities were considered to be the main factors for the increase of area in Zhalong wetland.
