Based on the landform information data and six phases of landscape data of the East China Sea, the landform types and landscape dynamics of the continental coast of the East China Sea were studied from 1990 to 2015, and the temporal and spatial distribution of landscape patterns under various topographical types were analyzed. The results showed that: (1) the landform type of the East China Sea coast was dominated by hilly landforms, followed by small rolling hills, plain, platform and medium rolling hills. The forest land was a dominated landscape type, followed by cultivated land and construction land. (2) The change of plain, platform and hilly landforms was mainly based on the conversion of cultivated land to construction land, while the small and medium rolling hills were mainly grassland to forest land. (3) The intensity of landscape change under different geomorphological units was in order of plain > platform > hills > small rolling hills > medium rolling hills. The degree of landscape change in 2005-2015 was less than that in 1990-2005, and the intensity of landscape changes was decreasing. (4) The landform type had great influence on the fractal dimension and stability index of the landscape. The fractal dimension of the waters was the largest in the plain. The fractal dimension of the cultivated land was the largest in the platform and hills, while the dimension of the small rolling hills was the largest in the unused land. The construction land had the largest fractal dimension and the opposite stability index. The cultivated land tended to be stable in low-lying landform types. Forest land and grassland were mostly distributed in hills and mountainous areas with higher elevations. The water area and construction land had the largest fractal dimension and stronger stability in the plain.
