摘要
构建生态安全格局对徽州生态系统稳定及推动区域经济可持续发展具有重要意义。本文以传统地域景观徽文化核心区为例,通过叠加生态敏感性评价、形态学空间格局分析(morphological spatial pattern analysis,MSPA)及景观连通性评价结果来识别生态源地,并运用电路理论提取生态廊道来判定生态夹点及障碍点。结果表明:2000、2010、2020年,研究区分别识别生态源地52、56、50个,总面积分别为2471.46、2481.12、2201.15 km2,分别占研究区总面积的25.6%、25.7%、22.8%;分别提取生态廊道124、141、113条,总长度分别为893.29、890.82、774.93 km;分别识别生态节点185、173、619处,最终构成以生态源点-生态廊道-生态节点组成的点线面相结合的徽文化核心区生态安全格局。最后,基于研究结果和区域生态现状,提出分区管控与生态修复、生态-文化复合网络构建、跨区域协作与生态补偿策略以提升区域生态可持续发展能力。
Constructing an ecological security pattern is crucial to stabilizing the ecosystem of Huizhou and promoting the sustainable development of the regional economy.Taking the core area of the traditional regional landscape in Huizhou culture as an example,the ecological sources were identified by superimposing the results of ecological sensitivity evaluation,MSPA(morphological spatial pattern analysis)and landscape connectivity assessment.Circuit theory was applied to extract ecological corridors and determine ecological pinch points and barrier points.The results show that 52,56 and 50 ecological source sites were identified in the study area in 2000,2010,and 2020,with total areas of 2471.46,2481.12,and 2201.15 km2,accounting for 25.6%,25.7%and 22.8%of the total area of the study area,respectively.A total of 124,141 and 113 ecological corridors were extracted,with total lengths of 893.29,890.82 and 774.93 km,respectively,and 185,173 and 619 ecological nodes were identified.These findings finally constitute the ecological security pattern of the core area of Huizhou culture,combining ecological source sites(points),corridors(lines),and nodes(surfaces).Based on the research results and the regional ecological status,strategies of zoning control and ecological restoration,construction of an ecological-cultural composite network,the cross-regional collaboration,and an ecological compensation mechanism are proposed to enhance the regional capacity for ecological sustainable development.
