- Abstract:
- Research on the development and utilization of low-slope hilly land resources was carried out in order to provide reference for alleviating land shortage and optimizing regional land resource allocation in the study area. Taking the Three Gorges reservoir area as the research area, we firstly defined the scope of low-slope hilly land resources, and then evaluated the ecological sensitivity and the importance of ecosystem service function based on the ArcGIS 10.1 platform. Based on the evaluation results, the ecological source was extracted. Then the minimum accumulated resistance model was used to construct the ecological security pattern in the study area. The ecological security pattern was superposed with the spatial distribution map of gentle-slope hilly land resources. Area of gentle-slope hilly land resources was 3 930.90 km2.There were four land development types:prohibited, limited,moderate and priority developments,their areas were 1 182.02 km2,1 775.19 km2,835.71 km2 and 137.98 km2, respectively. Most of the gentle-slope hills were prohibited and limited developments, and the area suitable for human development was small. The features of each development type were carried out, and corresponding development and utilization suggestions were put forward.The research method based on the ecological security pattern is conducive to promoting the rational development in the study area, which is conducive to the protection of the ecological environment.
