Abstract：Based on the remote sensing interpretation data of the Three Gorges Reservoir area (Chongqing section), the study area was
divided into 3 175 4×4 km evaluation units, and a spatial conflict measurement model for land use was constructed on the basis of the
characteristics of landscape ecology and land use system. Four types of land use spatial conflicts were classified on the basis of the
spatial conflict measurement value of the evaluation unit. Finally, the principal component analysis was carried out on the driving
factors of the land use space conflict of the study area. The results show that: 1)the spatial conflict in the study area is in a
rather severe state during the study period, and the proportion of the severe conflict type and the moderate conflict type is over
55%. 2) From the point of view of spatial distribution, the high value area of land use spatial conflict is concentrated in the
northeast and southwest regions and it shifts from the northeast to the southwest, with the passage of time. Finally, it expands
outward with the main urban area in southwest China as the center, while the types of general and minor conflicts are distributed in
the northernmost and southeastern fringes. 3) The change trend from 1990 to 2010 shows that some moderate conflict types have been
transformed into severe conflict types, indicating that the land use space conflicts in the study area are continuously strengthening,
and the conflict areas are converted from woodland and grassland to wetland, cultivated land and construction land. 4) The driving
factors of space conflict in the Three Gorges Reservoir area (Chongqing section) can be summarized as economic development, population
growth pressure and the construction of the Three Gorges Project.
