摘要
随着城市化的加速发展,构建绿色基础设施(GI)网络对于提升城市的生态韧性和推动可持续发展显得尤为关键。选取合肥市主城区作为研究对象,以2000、2010、2020年的土地数据为基础数据,通过PLUS模型对2030年合肥市主城区土地利用格局进行模拟预测;运用形态学空间格局分析法(MSPA)对该区域2030年的GI要素进行深入分析,识别出核心区面积为117.81 km^(2);对核心区的景观连通性进行了详细分析,共提取24块GI源地;利用电路模型提取48条GI廊道,基于Pinchpoint Mapper工具,增设47块踏脚石,通过踏脚石提取110条三级廊道,以此完善2030年合肥市主城区GI网络。该研究完善了未来合肥市主城区的GI网络,为城市发展提供了新的理论依据。
With the rapid pace of urbanization,the development of Green Infrastructure(GI)networks has become crucial for enhancing urban ecological resilience and promoting sustainable development.This study focuses on the main urban area of Hefei,uses land data from 2000,2010,and 2020 as the base data,and employs PLUS model to simulate and predict the land-use patterns of Hefei′s main urban area for 2030.The Morphological Spatial Pattern Analysis(MSPA)method is used to conduct an indepth analysis of the GI elements in the region for 2030,identifying a core area covering 117.81 km^(2).A detailed analysis of landscape connectivity within the core area is conducted,extracting 24 GI source patches.The circuit theory model is applied to identify GI corridors,resulting in the identification of 48 GI corridors.Based on the Pinchpoint Mapper tool,47 stepping stones are added,and 110 tertiary corridors are extracted through these stepping stones to improve the GI network for Hefei′s main urban area in 2030.This study contributes to the refinement of the GI network in Hefei′s main urban area,providing new theoretical insights for urban development.
