摘要:
 以福建东山岛为研究对象，采用形态学空间格局分析和景观连通指数提取连通性较好的生态源地斑块，基于最小累积阻力模型和重力模型，识别重要生态源地斑块，定量筛选廊道，构建了由19个生态源地和171条生态廊道组成的“源—廊—点”互通的海岛景观生态网络。结果表明，研究区生态网络面积共11 852.298 hm2，其中生态源地占52.76%，生态廊道占47.23%，生态踏脚石占0.01%。生态源地以林地、淡水水域为主；生态源地间的相互作用强度差异显著，总体上南高北低；生态廊道分布东南密、西北疏；生态源地与建设用地无明显冲突，廊道与建设用地冲突由南向北递减，二级廊道与建设用地冲突更加剧烈。研究结果可为东山岛生态网络构建和优化策略提供理论依据。
Abstract:
 As the development of urbanization,the connectivity between ecological patches is constantly affected.It is of great significance to the construction of urban ecological barrier by building ecological networks to enhance the overall connectivity of ecological land.Taking Dongshan Island in Fujian Province as the research object,morphological spatial pattern analysis and landscape connectivity index were used to extract ecogenic patches with better connectivity.Based on the minimum cumulative resistance model and gravity model,important ecogenic patches were identified,ecological corridors were quantitatively screened out.An island landscape ecological network composed of 19 ecological sources and 171 ecological corridors was constructed.The results indicated that the total area of ecological network was 11 852.298 hm2,in which the proportions of ecological functional zone,ecological corridor,network,ecological stepping stones accounted for 52.76%,47.24%,and 0.01%,respectively.The main ecological functional zone was mainly composed of forests and freshwater bodies.Significant differences in functional intensity were found between different ecological functional zones,high in the north,and low in the south,generally.Ecological corridors distributed densely in southeast,and sparsely in northwest.No obvious conflicts were observed between ecological functional zone and construction land.The conflict between ecological corridor and construction land decreased from south to north.The conflict between secondary corridor and construction land was more intense.The results provided theoretical basis for the construction and optimization of Dongshan Island ecological network.
