The vulnerability and ecological environment problems in coastal city have become the focus of global attention because the coastal area ecosystems have dramatic changes.Ecological regionalization is a processto evaluate the regional status anddivide different types of ecological unit byselecting the corresponding ecological environment indexes,which is based on the location,natural resources,environmental conditions and the development and utilization ofrequirements.Taking Beidaihe new district as an example,this paper established an indicator system of ecological regionalization by selecting 14 indicators from 3 ecological elements,namely ecosystem sensitivity,construction land suitability and security of the landscape pattern.And then it made a spatial analysis by using GIS technology,and divided the district into 4 ecological zones,i.e.,ecological conservation zone,eco-tourism zone,eco-service,and ecological agriculture zone,and 15 ecological sub-regions,andproposed some strategies for the future development and protection.%滨海区域生态系统不稳定,沿海城市的生态环境问题已经成为全球关注的重点.滨海地区生态区划是根据滨海区域区位、自然资源、环境条件及开发利用要求,选取相应的生态环境指标对区域状态进行评价,并划分为不同类型的生态单元的过程.文章以北戴河新区为例,从生态敏感性、建设用地适宜性和景观格局安全性等3个生态要素中共选取14个指标建立生态区划指标体系,运用GIS技术进行生态要素的空间分析,最终将北戴河新区分为生态涵养、生态旅游、生态服务和生态农业等4个生态主区以及15个生态亚区,并针对4个区分别给出了未来发展方向和保护对策.
