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.
