摘要
生态文明理念下,如何融合山、水、林、田、湖、草“生命共同体”理念开展国土空间规划,成为学界关注的核心问题。其中,生态安全格局作为城市可持续发展的屏障,是探索和实践“生命共同体”理念的良机。眉山市的生态禀赋优越,正面临社会经济快速发展的机遇,因而探索其生态安全格局构建意义重大。以眉山为研究区域,文章通过测算各类生态系统服务,以“生命共同体”理念识别52个生态源地;以遥感生态指数细化阻力面;基于电路理论识别54条生态廊道,从而构建该地区生态安全格局。最后,文章识别生态安全格局关键战略点和障碍区,以生态保护和修复视角优化生态安全格局,为眉山的城市可持续发展提供科学的生态技术支撑。
Under the philosophy of ecological civilization,integrating the community of life of mountains,rivers,forests,fields,lakes and grasses into the territorial spatial planning has become a core concern.Among them,the ecological security pattern,as a barrier for the sustainable development of the city,is the best opportunity to explore and practice the concept of community of life.Meishan has superior ecological resources and is facing the opportunity of rapid social and economic development.It is of great significance to explore the construction of ecological security pattern.Taking Meishan as the research area,this paper identifies 52 ecological sources based on the concept of community of life by measuring various ecosystem services.The paper further refines the resistance surface based on the remote sensing ecological index,identifies 54 ecological corridors based on the circuit theory,and constructs an ecological security pattern.Finally,it identifies the key strategic points and obstacle areas of the ecological security pattern,optimizes the ecological security pattern from the perspective of ecological protection and restoration,and provides scientific ecological technical support for the sustainable development of Meishan City.
