Abstract:: By using GIS and RS technology, the coastal wetland landscape changes of Yancheng form 1987 to 2007 were compared, its landscape changes and effect of ecological environment were analyzed. The result indicated that:(1) the coastal wetland landscape in Yancheng was disturbed intensively by human activity, landscape fragmentation was obvious. During 1987-2007, the average pattern area changed from 753.910 hm² to 124.470 hm²; the average dimension varied from 1.036 to 1.027;(2)the response of coastal wetland eco-environmental mainly performances as the coastal wetland in Yancheng is the key of reclamation, natural wetland area largely lost, the ninth five-years and the tenth five-years reclamation area near the city was 1/3 of the wetland area; the living environment of Red-crowned cranes faced threats, biodiversity declined, the population of red-crowned cranes wintering declined since 2000, wetland ecosystem, the water environment and soil environment in coastal wetland faced the threats.
