丘陵区生态安全格局构建分析——以广安市小井乡为例

Construction of Ecological Security Patterns in Hilly Areas——Taking Xiaojing Township of Guang’an City as an Example

区域生态安全格局构建是化解生态保护与经济发展之间矛盾冲突的有效途径,进行区域生态安全格局构建研究具有重要理论和现实意义。以位于西南丘陵地区的广安市小井乡为研究区,采用最小累积阻力模型(MCR)对丘陵区生态安全格局构建进行了研究,构建了由9个生态源、18个生态节点和19条生态廊道组成的“点—线—面”结合的丘陵区生态安全格局,在此基础上划分出生态核心区、生态缓冲区、农业耕作区、人类活动区共4个生态功能区,并提出相应的生态安全管控措施,以期为区域制定生态环境管理和生态风险防控措施提供科学依据,同时也为丘陵地区开展生态安全格局构建提供参考。

The construction of regional ecological security pattern is an effective way to resolve the contradiction and conflict between ecological protection and economic development. It is of great theoretical and practical significance to study the construction of regional ecological security pattern. In this paper, Xiaojing Township, Guangan City, located in southwest hilly area, is taken as the study area, and the minimum cumulative resistance model (MCR) is used to study the construction of ecological se curity pattern in hilly area.A "point-line-surface" combination of 9 ecological sources, 18 ecological nodes and 19 ecological corridors was constructed. On this basis, the security pattern is divided into four ecological functional areas: ecological core area, ecological buffer zone, agricultural farming area and human activity area, and the corresponding ecological security control measures are put forward. In order to provide scientific basis for regional ecological environment management and ecological risk prevention and control measures, and also provide reference for the construction of ecological security pattern in hilly areas.
