Abstract: Provided by State Key Laboratory of Resource and Environmental Information System, which belonged to the Institute of Geographic Science and Natural Resources Research, CAS, land cover data of Beijing-Tianjin-Hebei region in the year of 2000, 2005 and 2010 and 1:1 million digital topography data were used to have a research on land cover change of Beijing-Tianjin-Hebei region in recent 10 years based on different geomorphic units. Variations about the values of leading level, coverage degree and dynamic degree based on different geomorphic units were computed, which would help to have a further discussion about the spatio-temporal differentiation of land cover based on different geomorphic units. The results showed that the major changes of land cover in Beijing-Tianjin-Hebei region in the last ten years were the changes from arable land to the built-up and residential areas, which were dramatic in the geomorphic units of plains, hills and small undulating mountains, while arable land continued shrinking, especially in the geomorphic units of plains, terraces and hills. On the whole, differences about changes of land cover based on different geomorphic units in Beijing-Tianjin-Hebei region in recent 10 years were obvious. To be specific, land cover changes in the geomorphic units of plains, hills and small undulating mountains were dramatic. In the first five years from the year of 2000 to 2010, woodland and meadow had an obvious expansion, especially in the geomorphic units of plains, large undulating mountains and hills, while the expansion of woodland and meadow in the last 5 years from the year of 2000 to 2010 was not obvious. At last the significance of the research of land cover changes in Beijing-Tianjin-Hebei region based on different geomorphic units were discussed, which proved that the research was meaningful, what's more, some recommendations about the research on inherent relationship between geomorphic units and land cover changes were made, which paid more attention to the secondary classification system of both geomorphic units and land cover.
