The land coverage of the Yellow River Delta was observed as very dynamic during the last decades (Fig.1). This is caused by strong change in usage of natural resources and change in the agricultural system. The land cover map of 1979 displays a mainly untouched Yellow River Delta. After settlement foundation of Dongying city in 1983 the Delta region started to change due to population and settlement groth, river relocation, and intensification of usage of the land surface around the city of Dongying. Just from visual interpretation one can see (Fig.1) that the change is quite strong and fast - documented by classification of 4 time steps of Landsat imagery of the last 35 years.
