大型基础设施对地缘区人居环境的影响研究

基础设施的价值本源是对人的需求满足,通过与人居环境系统相互作用,表现为对良好人居环境的追求.以可持续的人居环境为目标,以系统思想分析大型基础设施和人居环境系统的作用机理,构建相互作用模型.即基础设施作为人居环境的承载体,通过能源动力、水资源、交通运输、邮电通讯、生态环境和防灾等子系统聚集,实现功能耦合,对自然、人类、社会、居住和支撑等子系统构成的人居环境系统产生相关作用.同时,人居环境系统的适应性促使其与基础设施影响反馈以构成闭环.以上海某典型交通枢纽地区的交通基础设施为例,设计了4个层次29个指标的大型交通基础设施对地缘区人居环境影响度指标体系,基于GA-BP混合算法的影响度模型进行测度.结果表明,大型基础设施与地缘区人居环境呈显著正向相关；社区配套设施完备程度是大型基础设施影响人居环境的主要传导途径；环境污染等指标反映出大型基础设施对人居环境的负面影响,是规划和建设的重点控制路径.

Effect Degree Modeling of Large-scale Infrastructure to Geo-regional Human Settlements

Infrastructure value originates from satisfaction of human beings needs,interacts with human settlement system,and reflects the demand for good environment.From a target of sustainable human settlements,it established a model to analyze the interaction mechanism between large-scale and urban human settlements.The infrastructure system couples by the accumulation of subsystems among energy power,water resource,transportation,post and telecommunication,ecological environment and disaster prevention,and intera...
