摘要
利用四幅不同时段的TM影像,获得青岛市城区的土地利用变化信息,并依此提取青岛市城市实体.在此基础上研究青岛市土地利用变化情况与青岛市城市实体的紧凑度与圆形率,并重点应用分型理论对青岛市城市实体进行研究,从计算结果看,2005年青岛市城市形态最为科学,而近年来青岛市城市扩展是盲目的、不科学的.
In this study, the land -use change information of Qingdao City was received using four different periods of TM images, while the Qingdao urban entity was extracted. Then the analysis in the land -use change information, the compactness and circularity ratio of the Qingdao urban entity were carried out based on the above studies. We focused on the application of fractal theory to study the entity of Qingdao urban entity. The results indicated that the urban morphology of Qingdao in 2005 is the most scientific while the urban expansion in recent years is blind and unscientific.
