沈阳市绿地生态信息获取与数据库建设研究

Acquisition and Database Construction for Ecological Information of Green Space in Shenyang City

随着城市化进程的不断加快,绿地在城市生态系统中发挥的作用越来越大,为快速、准确获得城市绿地生态信息,更有效地对城市绿地进行规划与管理。以沈阳市为例,采用Quickbird遥感影像技术,结合GPS实地定位调查验证对城市绿地进行系统调查,建成了基于ArcGIS平台的城市绿地生态信息空间数据库。该数据库系统效率高,稳定性好,用户界面友好,易于操作,可扩展性强,可使用数据、图像和图形三种形式来定性、定量的描述、分析城市绿地生态功能,能有效地管理不断变化的城市绿地系统的空间和属性数据。

With the rapid development of urbanization, green space plays a more and more, important role in urban ecological system. In order to acquire the ecological information of urban green space quickly and accurately and to plan and manage urban green space more effectively, the urban green space in Shenyang City was systematically investigated by using Quickbird remote Sensing image technology and global position system （GPS） site survey, and a spatial database for ecological information of urban green space was constructed based on AreGIS platform. This database has high system efficiency, good stability, friendly user interface, easy operation way and strong expansibility; it can use three ways （data, image and graphics） to qualitatively describe and quantitatively analyze ecological functions of orban green space, and it also can effectively manage spatial arid attribute data of continuously changeable urban green space system.
