摘　　要：以万分之一彩红外航空遥感图像为主要信息源,以ArcGIS和ERDAS为主要研究工具,对宁波市的城市绿化生态环境效益及其空间特征进行了研究.研究结果表明:不同道路的绿化系统具有不同的相对环境效益;宁波市城市绿化生态环境效益分布不均;相对绿化环境效益与绿化覆盖率密切相关.研究结果丰富了城市绿化评价指标,为城市绿化系统的设计,特别是为不同环境要求的功能区绿化系统设计、城市绿化群落布局的合理性评价和城市绿化规划提供有价值的技术参数.The studying object is urban afforestation in Ningbo city and the main data is color-infrared remote sensing image,which was made in 1998 and its scale is 1 ： 10000.ArcGiS and ERDAS-based, the econvironmental effects and the spatial character of the urban afforestation are studied. The results indicate： 1） Different situation of afforestation of the road system has differential effects. 2） Eco-environmental effect is not balanced in Ningbo city. 3） There is correlativity between the relative environment effect and the rate of green coverage in these regions. The relative environment effect will be large, if there is a big coverage rate of green coverage in a particular area. 4） The method provides an important index for the evaluation of urban green area and is useful for studying of the green environmental benefit. At the same time, the findings of the study will also provide useful parameters for the design of green systems, especially to design for regions with special demands of green reg;ons, and rationality for urban green community distribution and urban green planning.
