Based on the 15 m×15 m spatial distribution raster data of 11 types of land use in 2015 and the landscape pattern index, the landscape pattern characteristics of land use in the counties, floodplains and flood detention areas along the wide reaches of the Lower Yellow River, and gradient characteristics of the landscape patterns of land use in the 18 2km-buffer zones on both sides, are compared and analyzed. The results show that the dry farmland is the dominant landscape within the counties along the wide reaches, followed by the rural residential land, and they account for more than 80% of the total area of the counties. The paddy fields and the other categories of waters have a certain scale and the scale of the grassland is small. Influenced by factors such as functional orientation and natural conditions, there are obvious spatial differences in land use landscape patterns in the counties, floodplains and flood detention areas along the wide reaches of the Lower Yellow River. There are large-scale and densely-distributed construction land in the extra-floodplains area of the counties, the landscape fragmentation of which is high and the patch shape is complex. The landscape diversity of the Dongping Lake flood detention area is high, showing a complex ecological landscape with waters as the main body, and in the other two flood detention areas, the scale of woodland and grassland is small, the patch density and the landscape heterogeneity is low. The overall landscape fragmentation in the wide reaches’ floodplains is lower than that in the extra-floodplains area, the landscape diversity of the wandering reaches’ floodplains is relatively high, and the construction land is relatively large. Within 6 km of the two sides of the wide reaches, the paddy fields and the other categories of waters are large in scale and densely distributed, the scale of the urban land is small, and the overall landscape diversity in this region is high and relatively fragmented; the transition region is from about 6 km to 18 km; the landscape patterns tends to be stable over 20 km away.
