摘　　要：选取太原城区为研究区域,以1∶2.5万彩红外航空影像为信息源,应用VIRTUOZO对影像进行解译,在MAPGIS界面下根据解译结果提取研究城区绿地缀块信息,并建立数据库.在此基础上,对8种绿地类型的缀块大小、形状以及整体格局进行定量分析,研究结果表明:(1)城区绿地缀块大小分布极不均衡,8种类型都是以小缀块为最多,单位附属绿地和公园绿地占总面积的比例最大,优势相对较强;(2)居住绿地与圆形最接近,形状较紧凑;行道树和防护绿地与圆形相差最大,形状较松散;(3)各种绿地类型面积差距不大,均匀度较高,优势度较小.居住绿地的破碎化程度最大,公园最小.城市村落分离度最大,单位附属绿地和居住绿地分离度最小.The greenland landscape of Taiyuan City zone was studied by using large-scale aerial photographs （1 ： 25 000） as an information source. A greenland map of this city was made through MAPGIS software, and a related database was set up. Based on the database,the current landscape pattern characteristics were analyzed, which include patch size, patch shape and landscape pattern as a whole. The results were as follows ： （1）The distributions of patch size are extremely uneven in eight types of greenland,each of which includes many small patches. The area of affiliated greenland or parks is bigger than that of other types, so both of them are the main components. （2）The residential greenland is similar to circle and more compact. The shape of shade trees is greatly different to circle and quite loose. （3）There aren＇t great disparities in areas among all types. So the degree of evenness is high and the dominance is low. The degree of fragmentation of residential greenland is the highest ,that of parks lowest. The degree of separation of urban country is highest, those of affiliated and residential greenland lowest.
