摘要: 为探寻坡度分布与用地类型的关系,根据Landsat8影像和DEM提取了洛阳市偃师区坡度与用地类型数据,对其关系进行分析,得出偃师区坡度较缓、用地类型分布较为合理,适宜人类居住、生活;用地类型主要受6°、15°、35°坡度影响较大,草地面积分布在≤6°范围内低于建设用地, >6°后则大于建设用地;坡度<15°时耕地面积占据主导地位,>15°坡度林地面积则居于支配地位;坡度>35°后除林草地外,其他用地鲜有分布;用地类型多样性指数在6°~15°坡度内达到最大,是人类活动的密集区。偃师区根据地形坡度合理布局用地类型,既降低了水土流失、增加了土壤有机质含量,也提高了人民生活水平,其经验值得借鉴与推广。

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
