摘　　要：构建科学合理的生态安全格局是高水平保护区域生态系统、推进生态文明建设、保障国土空间安全的关键路径。借助生态系统服务供需理论,从自然生态基底和人类经济活动耦合协同的视角,指出生态系统服务供需水平核算及评估是构建生态安全格局的基础和关键。引入电路理论,提出基于生态系统服务供需协同的“源地识别—阻力面建立—廊道提取”生态安全格局构建思路及框架。以安徽省为实例,从食物供需服务、产水服务、固碳服务及游憩服务4个方面对安徽省生态系统服务供需情况进行评价,确定安徽省生态源地、提取生态廊道、识别生态夹点和障碍点,并划定生态保护区、生态修复区和生态建设区等3类生态功能分区,形成安徽省“两带、两轴、两屏、三区、多点”的生态安全格局,为安徽省国土空间生态修复和生态经济可持续发展提供科学依据。Construction of a rational ecological security pattern is a key path to protect regional ecosystem,promote ecological civilization development,and safeguard national space security.Based on the demand-supply theory in ecosystem service,it is argued that the calculation and assessment of demand-supply level of ecosystem service are the foundation and key points of establishing ecological security pattern from the perspective of integrating natural ecology and economic activity.With the introduction of circuit theory,the concept and framework of ecological security pattern through"source identification-resistance surface establishment-corridor extraction"are put forward.With Anhui province as an example,the demand-supply of the ecosystem service is assessed from four aspects:food demand-supply,water production,carbon sequestration,and recreation,then the provincial ecological sources,corridors,pinch points,and barrier points are identified,and three types of ecological zones are delineated:ecological protection zone,ecological restoration zone,and ecological construction zone.An ecological security pattern of"two belts,two axes,two screens,three zones,multiple points"is formulated,offering scientific guidance for territorial space ecological restoration and sustainable development of ecological economy in Anhui province.
