摘要
山地—平原型城市的土地利用冲突区识别对于预防区域生态系统失稳至关重要。从生态安全视角出发,以西安市长安区为例,融合生态系统服务重要性-生态敏感性-景观连通性的多维评价方法构建生态安全格局;通过生态安全格局与人为活动区域(耕地、建设用地)的叠合分析识别冲突区,并据此制定管控策略。结果表明:1)长安区共识别生态源地79处(总面积867.57 km^(2)),潜在生态廊道178条(总长258.59 km);2)土地利用冲突类型被细分为12类,分布于秦岭北麓山前区域以及主要流域中下游;3)根据冲突区分级结果,划定不同级别的冲突管控区,即一级管控区(建设用地/耕地与生态源地等冲突)、二级管控区(与中安全缓冲区冲突)、三级管控区(与高安全缓冲区冲突)并制定相应级别的管控策略。因此,本研究在提升冲突区识别准确性的同时减少了土地利用冲突发生,这种差异化管理有助于管控实施的针对性和落地性。
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 km^(2))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.
