摘要:  以三峡库区重庆段为研究区,基于生态安全视角,以生态敏感性与生态系统服务功能重要性评价结果提取生态源地,采用最小累积阻力模型构建生态安全格局,在生态安全格局基础上对三峡库区重庆段2015年的土地利用冲突进行识别,以期为三峡库区重庆段土地利用规划管理提供参考依据。结果表明:(1)耕地冲突分布较为分散,极严重冲突集中分布于奉节县、开县、石柱县与涪陵区,严重与较严重冲突集中分布于重庆市主城区的外围区县,一般与不冲突集中分布于长寿区和巴南区;(2)建设用地冲突分布较为集中,极严重冲突集中分布于重庆市主城区,严重和较严重冲突分布较为分散,各区县均有分布,一般和不冲突也集中分布于重庆市主城区,且大多位于极严重冲突的外围;(3)综合土地利用冲突的极严重冲突集中分布于重庆市主城区的中心区域与奉节县,严重与较严重冲突各区县均有分布,一般与不冲突集中分布于极严重冲突的外围区域。 

Abstract: The Chongqing section of Three Gorges reservoir area was used as the case study area. From the perspective of ecological security,ecological sources were identified via evaluation of ecological sensitivity and ecosystem service value. Ecological security pattern was built via the Minimum Cumulative Resistance model. Based on Ecological security pattern,the land use conflict was identified of the Chongqing section of Three Gorges reservoir area in 2015. we expect the research results will provide reference for the land use planning and management. The results show that: (1)The spatial distribution of cultivated land conflict was relatively scattered,the type of very serious conflict was mainly distributed in Fengjie,Kai,Shizhu and Fuling counties. The type of serious conflict and lower serious conflict were mainly distributed in the peripheral counties of the main city of Chongqing. The type of general conflict and non-conflict were mainly distributed in Changshou and Banan counties;(2)The spatial distribution of construction land conflict was relatively concentrated,the type of very serious conflict was mainly distributed in the main city of Chongqing. The spatial distribution of serious conflict and lower serious conflict were relatively scattered. The type of general conflict and non-conflict were also mainly distributed in the main city of Chongqing,and located on the periphery of very serious conflict;(3)The type of very serious integrated land conflict was mainly distributed in the central of the main city of Chongqing and Fengjie county. The type of serious conflict and lower serious conflict were distributed in every county. The type of general conflict and non-conflict were mainly distributed in the peripheral areas with very serious conflict.
