By taking urban greening of Tai' an City of Shandong Province for example,selecting remote sensing image Quickbird with high resolution, and combining visual interpretation with automatic classification of the computer,based on urban green space systematic planning map,green space information of the built - up area has been selected for the research centering on green lands in urban parks,productive green lands,green lands attached to residential areas and units,green lands attached to the road,other green lands,water surfaces and so on. Through the statistics and analysis,the distribution condition of each type of urban green land has been obtained,and some suggestions have been proposed in view of existing problems of urban greening. It should enhance the construction of green lands in urban parka, residential areas and units, improve road greening level,implement vertical greening,increase the area of productive green lands and fully make use of idle lands.%以山东省泰安市城市绿化为例,选用高分辨率遥感影像Quickbird,采用目视解译和计算机自动分类相结合的方法,结合城市绿地系统规划图,围绕城市公园绿地、生产绿地、居民区及单位附属绿地、道路附属绿地、其他绿地、水面等,提取泰安市建成区绿地信息并加以研究.经过统计分析,得出各类城市绿地的分布现状,并针对城市绿化存在问题给出一些建议,认为应加强公园绿地、居民区和单位附属绿地建设,提高道路绿化水平,推行立体绿化,增加生产绿地面积并且充分利用闲置土地.
