摘　　要：生态优先和绿色低碳的高质量城市发展已成为中国式现代化城市建设的方向。国土空间规划也对生态安全和土地要素配置提出了新的要求。生态用地具有典型的“边缘”景观特质,其生态功能和生态系统服务功能给城市带来了社会、经济和文化等多重效益的叠加。文章以成都市为研究区域,运用景观生态学的研究方法,对城市的景观格局指数进行辨析和量化,解读生态用地产生的边缘效应及其支撑、扩散和过滤功效。通过成都生态建设在城市空间、功能和社会文化3个方向上的实践,验证了生态用地产生的边缘正效应能够促成城市与自然环境的协同融合,推动城市发展。文章进一步提出了生态用地建设与环境保护的国土空间规划策略。Prioritizing ecology and pursuing green,low-carbon,high-quality urban development has become the direction for urban construction in the context of Chinese-style modernization.Territorial spatial planning has also introduced new requirements for ecological security and land resource allocation.Ecological land,characterized by its distinctive“edge”landscape features,provides multiple overlapping benefits—social,economic,and cultural—through its ecological functions and ecosystem services.Taking Chengdu as the study area,this article employs landscape ecology research methods to analyze and quantify the city's landscape pattern indices,interpreting the edge effects of ecological land and its functions in support,diffusion,and filtration.By examining Chengdu's practices in ecological construction across three dimensions—urban space,functionality,and socio-cultural aspects—the study validates that the positive edge effects of ecological land can foster the synergistic integration of urban and natural environments,thereby driving urban development.The article further proposes territorial spatial planning strategies for ecological land construction and environmental protection.
