基于高分辨率遥感影像的平潭综合实验区景观格局分析
Landscape pattern analysis of Pingtan Comprehensive Experimental Zone based on high spatial resolution remote sensing imagery

为揭示平潭综合实验区自成立至今的生态环境发展态势，以期为实验区后续开发建设中的生态建设和保护提供科学依据. 利用RS和GIS技术，基于2016年SPOT-7遥感影像，对福建省平潭综合实验区完成初期建设目标后的区域景观格局和景观脆弱性开展研究，结果表明：平潭岛中部区域的景观破碎化程度大于外周区域，整体景观脆弱性由北至南呈现“低-高-低-中”的空间分布结构. 平潭综合实验区在下一阶段的开发建设中应及时制定并落实科学有效的景观生态保护措施，以遏制其景观破碎化加剧的趋势.
In order to reveal the ecological situation and development trend of Pingtan Comprehensive Experimental Zone since its establishment，and provide scientific basis for following development and construction. Based on the remote sensing and GIS techniques，the landscape pattern and landscape fragility of Pingtan Comprehensive Experimental Zone after the initial construction were analyzed by using the SPOT-7 image dated on February 7，2016. The results showed that the landscape fragmentation in the central area of Pingtan Island was greater than that in the peripheral area，and the overall landscape fragility from north to south presented the spatial distribution structure of “low- high- low- middle”. Therefore，in order to curb the broken trend of the landscape of Pingtan Comprehensive Experimental Zone，some effective ecological protection measures must been developed and implemented during the construction
