Based on the remote sensing, geographic information systems technology and the basic principles of landscape ecology, we analyzed the dynamics of suburban agricultural landscape changes in Kaifeng city during the urbanization process from 1975 to 2004. The results showed that: in 1975, the agricultural landscape features were characterized by a typical suburban agricultural landscape pattern, and landscape types were mainly dry land and paddy fields landscape types, followed by the construction land landscape types. Landscape was composed of a mosaic of agriculture, urban and natural vegetations. In 2004, urbanization in the western suburbs was obvious, with dense buildings and roads, and the main types were irrigated land and construction land landscapes. The northern suburbs basically remained the countryside agricultural landscape. However, from 1975 to 2004, in the two sampling areas, landscape dynamics were both significant. The areas of dry land, paddy fields, scrub and sandy landscape type decreased, and reed landscape types disappeared, while the area of roads, ponds, rivers, green land, construction land, irrigated land landscapes increased. Landscape changes have a close relation with urbanization and diverting water from the Yellow River.
