摘 要:在生态安全背景下,构建生态安全格局是生态文明建设的重要基础之一。本文选取长春市九台区为研究对象,基于生态服务功能重要性评价、最小累计阻力模型、电路理论确定生态源地、生态廊道和生态夹点,从而构建九台区生态格局。研究结果表明:①九台区生态源地共829.93 hm^(2),占研究区总面积的24.62%,土地利用类型为林地和水域;②九台区生态廊道共34条,呈辐射状分布在生态源地之间,主要分布在九台区中部和东北部;生态夹点8个,零散分布在九台区南部、西南部和东北部,维护生态源地之间的连通性。对九台区生态源地、生态廊道和生态夹点分类保护和修复,重点保护九台区生态源地,实施严格监管,使其更好地发挥生态功能;将生态廊道和生态夹点划入国土空间规划的生态控制区,在对生态环境不产生破坏的前提下,适当进行开发建设活动。本文研究结果对于九台区提出更具前瞻性的生态设计规划、城镇空间发展预景和土地利用空间布局的优化战略具有重要意义。In the context of ecological security,building an ecological security pattern is one of the important foundations for the construction of ecological civilization.This paper selects Jiutai District in Changchun City as the research object,and determines the ecological source,ecological corridor and ecological pinch based on the importance evaluation of ecological service function,minimum cumulative resistance model and circuit theory,so as to construct the ecological pattern of Jiutai District.The results show that the ecological source area of Jiutai district is 829.93 hm^(2),accounting for 24.62%of the total area of the study area.The land use types are forest land and water area.There are 34 ecological corridors in Jiutai District,which are distributed among the ecological sources,mainly in the middle and northeast of Jiutai District;there are 8 ecological pinch points,which are scattered in the south,southwest and northeast of Jiutai District,so as to maintain the connectivity between the ecological sources.The ecological sources,ecological corridors and ecological pinch points in Jiutai District are classified,protected and restored.The ecology of Jiutai District is mainly protected source,implement strict supervision to make it better play its ecological function.The ecological corridor and ecological pinch are included in the ecological control area of land spatial planning,and development and construction activities are carried out appropriately on the premise of no damage to the ecological environment.The results are of great significance for Jiutai District to put forward ecological design planning,urban spatial development preview and land use spatial layout optimization strategy.
