摘 要: 在城镇化地区优先构建科学合理的区域生态安全格局,对于实现我国生态文明建设目标和新型城镇化发展战略具有重大的现实意义。本文以广东省为例,通过选择水资源供给、水源涵养、生物栖息地提供等关键生态系统服务指标并应用RS、GIS等空间技术方法识别其相应关键空间,综合叠加形成多层次、连续完整的区域生态安全体系,并构建"点、线、面"要素完善的区域生态安全战略格局,进而从城镇空间的区域格局、都市区结构、城镇建设三个层面提出具有针对性的空间策略,以期为优化城镇空间布局提供有效指引。 priority for constructing regional ecological security pattern in urbanization area is of great practical significance to realize the goal of ecological civilization construction and the development strategy of new urbanization.This paper takes Guangdong Province as an example,through the selection of water supply,water conservation,habitat providesand so on as the key ecosystem services indicators,then uses RS,GIS and other space technology methods to identify the corresponding key space,and builds the regional ecological security strategic pattern with perfect elements of 'point,line,surface',and thenputs forward the targeted spatial strategyfrom thethree aspects ofregional pattern,metropolitan area structure,and urban construction of urban space,in order to provide effective guidance for optimizing urban spatial layout.
