基于遥感影像的双台河口保护区景观格局变化分析

Landscape pattern change analysis is 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 GIS platform, landscape classification image were got by visual interpretation. According to the analysis of landscape pattern index, urban construction land area increased quickly, fragmentation became larger, agricultural land also increased in a slight range; Meanwhile, reed wetland landscape reduced, fragmentation exacerbated. To make wetland landscape change better, protected area need to be planned rationally, and management actions need to be improved.
