The designation of the ecological line can protect the basic ecological city environment, the city group structure, and the limited urban land resources in order to relieve the urban ecological resource pressure. In the processing of remote sensing image the useful information is extracted. Based on ArcGIS model, Huangdao District of Qingdao city is taken, as an example in the form of a moder that can be visualized in ArcMap. And ArcCatalog is adopted in the model to store and control the information data.%生态控制线的划定,可以保护城市基本生态环境,维护城市组团结构,对城市有限的土地资源进行强制性保护,从而缓解城市生态资源面临的巨大压力.通过遥感图像的处理提取有用信息,基于ArcGIS模型建立工具,以青岛市黄岛区为例建立模型,在ArcMap中实现可视化,并且用ArcCatalog进行模型的数据存储与管理.
