Classification and Identification of Mountain-Plain Urban Land Use Conflicts from the Perspective of Ecological Security
The identification of mountain-plain urban land use conflict areas is crucial for preventing the destabilization of regional ecosystems.Taking Chang'an District in Xi'an as a case study area,the study uses a multi-dimensional evaluation approach that integrates the significance of ecosystem services,ecological sensitivity,and landscape connectivity to construct an ecological security pattern from an ecological security perspective.By conducting an overlay analysis of the ecological security pattern with areas of human activities(arable land and construction land),conflict areas are identified,and management strategies are formulated accordingly.The results indicate:1)A total of 79 ecological source areas(the total area at 867.57 km2)and 178 potential ecological corridors(the total length at 258.59km)are identified in Chang'an District;2)Types of land use conflict are subdivided into 12 categories,distributed in the piedmont area north of the Qinling Mountains and in the middle and lower reaches of the main river basins;and 3)Based on the classification of the conflict areas,conflict control areas of different levels are delineated,including the first-level control areas(conflicts between construction land/arable land and ecological source areas),the second-level control areas(conflicts with medium ecological buffer zones),and the third-level control areas(conflicts with high ecological buffer zones),and the corresponding control strategies are formulated.In this sense,the study enhances the accuracy of identification of conflict area,while reducing the occurrence of land use conflicts.This differentiated management approach is helpful for improving the targeted implementation of control measures.
