摘要: 加强生态网络建设是改善城市生态环境和保护生物多样性的重要举措。以宁夏灵武市为例,基于遥感及社会经济数据,采用形态学空间格局分析法、Linkage Mapper以及改进的重力模型方法,分析了生态网络与社会经济景观“双网”格局及相互关系。结果表明: 2000—2020年,灵武市的土地利用/覆被发生了剧烈变化,沙地、草地面积锐减,林地、建设用地面积增加,工业区快速扩张;“双网”在连通性和稳定性方面均有所提升。人类活动密集区分布于城市区、绿洲农业区以及宁东能源工业区,生态源地及生态廊道主要分布于自然保护区中部,部分延伸到其他功能区;交通廊道呈现在农业区和宁东能源工业区密集分布、在两区之间贯通的“H”型格局,“双网”均以各自功能区空间为核心且存在交织分布;“双网”呈现从冲突走向协同发展的态势,空间上存在明显分区及交互情况,农业区和宁东能源工业区的生态均存在初期破坏、后期改善的情况。今后,需加强生态保护与社会经济发展的相互协调,可通过生态源地与廊道质量提升、生态节点建设与生态干扰点修复等组合措施提升生态质量。

Abstract: Strengthening ecological network construction is an important measure to improve urban ecological environment and protect biodiversity. With Lingwu City of Ningxia as an example, based on remote sensing and social and economic data, we comprehensively analyzed the “double network” (ecological network and social and economic landscape) pattern and their relationship by using morphological spatial pattern analysis, Linkage Mapper, and improved gravity model. The results showed that land use/cover changed dramatically from 2000 to 2020 in Lingwu City. The area of sandy land and grassland decreased sharply, that of forest and construction land increased, and industrial zones expanded rapidly. The connectivity and stability of “dual network” were improved. The intensive areas of human activities were distributed in urban area, oasis agricultural areas, and Ningdong energy industrial zone. The ecological source areas and ecological corridors were mainly distributed in the middle of the nature reserve, while some extended to the other three functional areas. The transportation corridor presented an “H” pattern that was dense in oasis agricultural area and Ningdong energy industrial zone, and connected between the two regions. The “double network” were centered around their respective functional area spaces and had interwoven distributions. The trend of the “double network” changed from conflict to coordinated situation, with obvious zoning and interaction in space. The oasis agricultural area and Ningdong energy industrial area destroyed the eco-logy in the early stage and improved that in the later stage. In the future, it is necessary to strengthen the coordination between ecological protection and social and economic development, which could improve ecological quality by combining measures such as improving the quality of ecological sources and corridors, constructing ecological nodes, and repairing ecological disturbance points.
