| 摘 要： | 景观格局变化分析是研究保护区生态环境质量的重要参考和依据，分析这种变化造成的生态效应对物种多样性保护具有重要意义。对2003年和2015年两幅双台河口保护区遥感图像，在地理信息系统（geographic information system，GIS）平台下通过人工目视解译得到景观分类图像。根据景观格局指数分析得出，从2003年到2015年，双台河口区域城建用地面积大幅增加，破碎化程度变大，农业用地也有小幅度增加；而芦苇湿地景观面积则减小，破碎化呈加剧趋势。要合理规划保护区建设，加大管理力度，使保护区湿地景观得到有效恢复。 |

| Abstract： | Landscape pattern change analysis is an important reference and basis for studying ecological environment quality of protected area. Analysis of ecological effects resulting from this change is important for the conservation of species diversity. In this paper, through two remote sensing images of Shuangtai estuary protected area in 2003 and 2015 in geographic information system (GIS) platform, landscape classification image were obtained by visual interpretation. According to the analysis of landscape pattern index, urban construction land area in Shuangtai estuary increased quickly, fragmentation became larger, and agricultural land also increased in a slight range; while reed wetland landscape area reduced, and fragmentation exacerbated. To make wetland landscape change better, protected area need to be planned rationally, and management actions need to be improved to effectively recover the wetland landscape of protected area. |
