遥感和GIS支持下的城市植被制图及其特征分析

 以上海城市植被为研究对象，探索城市植被的分类理论和方法，提出一套适用于城市植被分类与制图的方法。根据城市植被信息获取的方式以及生态-外貌分类原则，建立了基于植物生活型的、可用图形表示的城市植被分类体系，分天然与半天然植被和人工植被两个大类，共有9个植被型和34个植被亚型。在遥感和地理信息系统(GIS)技术的支持下，建立研究区的城市植被信息数据库，并在此基础上对城市植被类型的特征以及与土地利用的关系进行分析比较，以期掌握城市植被类型的数量特征及其空间分布，同时按不同分类级别用计算机进行城市植被制图。城市植被

ANALYSIS ON THE CHARACTERISTICS OF URBAN VEGETATION AND ITS MAPPING BASED ON REMOTE SENSING AND GEOGRAPHIC INFORMATION SYSTEM

A set of methodologies for urban vegetation classification and mapping are suggested. The urban vegetation classification system was established based on the acquirement method of urban vegetation information and eco_physiognomy classification principle. The system can be mapped according to plant life form. There are 9 vegetation types and 34 sub_vegetation types which are natural or semi_natural vegetation and artificial vegetation. The database for sample area was set up by using remote sensing data and Geographic Information System(GIS), based on which the relationship between the urban vegetation and the land_use pattern was analyzed in order to know the characteristics of urban vegetation well. Spatial positioning and quantification of urban vegetation laid a foundation for the estimation of ecological benefit of urban vegetation and urban ecological planning and management.
