摘要: 双台河口国家级自然保护区位于辽河下游入海口,该地区湿地发育,区域内土地利用/覆被类型多样。本文基于5个不同时相的Landsat卫星系列TM、ETM和OLI-TIRS遥感影像,采用监督分类法对影像进行分类处理,然后结合GIS空间分析与数理统计方法,分析了1984—2013年期间双台河口国家级自然保护区土地利用/覆被变化情况。结果表明:1984—1992年期间芦苇沼泽和养殖水域大面积增加,天然水域和滩地大面积减少,养殖水域的单一土地利用动态度最大;1992—2000年期间耕地和滩地面积快速增长,天然水域和芦苇沼泽面积快速减少,研究区综合土地利用动态度最大;2000—2007年期间,养殖水域大面积增加;2007—2013年期间,城建用地大面积增加。双台河口自然保护区LUCC受多种因素影响,人口、经济和政策等是主要的社会经济因素,不同时期各社会经济因素对LUCC的推动作用有所差异。

Abstract: The national nature reserve of Shuangtai River Estuary is located in the lower reaches of Liaohe River Estuary, there are many wetlands in the region, the land use/cover types of which are various. The author analysed the land use and land cover (LUCC) and their driving forces in the national nature reserve of Shuangtai River Estuary from 1984 to 2013 by utilizing the Landsat TM, ETM, OLI-TIRS remote-sensing images of 5 different periods in the past 30 years. The method which combines GIS spatial analysis with mathematical statistics was adopted. The results show that the marsh reeds area and aquaculture area increased widely, the natural water area and beachland area diminished widely, the single land use dynamics of aquaculture area was the largest during 1984 to 1992. The farmland area and beachland area increased fast, the natural water area and marsh reeds diminished fast, the comprehensive land use dynamics was the largest during 1992 to 2000. The aquaculture area increased widely during 2000 to 2007. The construction land increased widely during 2007 to 2013. The LUCC of the national nature reserve of Shuangtai River Estuary was influenced by many factors and population, economy, policy were the mainly social economic factors.The performance of each factors were different during different periods.

Key words: remote sensing, GIS, Shuangtai River Estuary, LUCC, driving forces
