Abstract: In order to explore the relationship between slope distribution and land use type, the data of slope and land use type in Yanshi district of Luoyang city were extracted based on Landsat8 image and DEM, and the relationship was analyzed. The results showed that the slope of Yanshi district was slow and the distribution of land use type was reasonable, which was suitable for human living and living. The land use type was mainly affected by the slope of 6°, 15° and 35°, and the grassland area distribution was lower than that of construction land within ≤6°, but larger than that of construction land after >6°. When slope is less than 15°, arable land is dominant, while woodland is dominant when slope is greater than 15°. After slope >35°, there is little distribution in other land areas except forest and grassland. The diversity index of land use type reaches the maximum within the slope of 6°~15°, which is the intensive area of human activities. The rational layout of land use types in Yanshi district according to terrain slope not only reduces soil erosion, increases soil organic matter content, but also improves people's living standard, and its experience is worth learning and popularizing.

Key words: land use type, slope, image, diversity index
