基于景观生态安全格局评价的佛山市生态基础设施构建研究

Study on the Construction of Ecological Infrastructure in Foshan City Based on the Evaluation of Landscape Ecological Security Pattern

城市化作为全球性的事件,对地球支持系统和生态服务功能会带来长久的影响。快速城市化地区无序扩张造成了土地资源的浪费、生态环境的恶化,同时加剧了潜在的区域生态风险。从土地自然演进的视角,基于景观生态安全格局理论,分析了佛山市水文系统安全格局、地质灾害安全格局、生物保护安全格局以及乡土文化安全格局。在GIS与RS空间技术支持下,构建了低(底线)、中(适宜)、高(理想)3种不同安全水平的佛山市生态基础设施,并识别了建设用地与生态基础设施的生态冲突空间。

As a global event, urbanization will bring long-term effects to the supporting systems and ecosystem services of the whole world. Disorder sprawl to a waste of land resources and ecological environment deterioration aggravated ecological risk in the rapid urbanized region. From the perspective of the natural evolution of land, the hydrological system security pattern, geological disasters security pattern, biological protection security pattern and local culture security pattern were evaluated based on the landscape ecological security pattern theory. Three different security levels of ecological infrastructure of Foshan City including the low（bottom）level, medium （appropriate） level and high （ideal） level were built under the support of GIS and RS spatial technology. Ecological conficts space have been identifed between construction land and ecological infrastructure.
