摘要
[目的]识别石家庄市生态安全格局,提出优化方案。[方法]采用现场调研和遥感影像解析,辨识对区域生态安全有重要影响的生态核心区和廊道;以城市建成区、工业区、交通干线等人工设施及土地建设适宜性分析得出的适宜建设区作为生态阻力消耗区,采用"源-消耗反馈链接"分析寻找最小阻力廊道。[结果]建立了以新的生态核心区、缓冲区和"三横三纵"生态廊道为主体的新生态格局。[结论]通过生态安全格局优化,石家庄市区域的生态安全性显著提高,可为区域经济社会发展提供更为稳定的生态保障。
[Objective] The aim was to recognize the ecological security pattern in Shijiazhuang and propose optimization scheme.[Method] Through field survey and remote sensing image analysis,ecological core areas and corridors having important influence to regional ecological safety were recognized.In urban built-up area,planning construction areas,road,rail and other artificial facilities and suitable construction areas derived from suitability analysis as ecological resistance consumption area,corridor of least resistance was found using of Source Grid-Cost Back link model.[Result] A new ecological pattern was built based on the new ecological core area,buffering area and ＂3 east to west and 3 north to south＂ corridors as main structure.[Conclusion] The ecological security of Shijiazhuang regional pattern was markedly improved,and can provide a more stable ecological protection for social and economic development in Shijiazhuang.
