摘　　要：以RS和GIS技术为支撑,基于多时相Landsat遥感数据,采用人工解译方法提取锦葫沿海四个城市空间特征信息,结合地学统计方法,定量研究了城市扩张速度、强度、紧凑度及城市用地分维数四个指标。结果表明:1990-2010年城市扩张面积为8166 hm2,扩张速度为7.37%,扩张强度为0.11;城市用地扩展速度最快的是葫芦岛市;扩展强度最大的是锦州;锦州市、葫芦岛市城市空间越来越分散;葫芦岛市的城市用地边界最为复杂。该结论可以作为城市规划的前期研究,并为城市空间扩展的驱动机制研究及空间扩展模拟打下基础。Supported by RS and GIS, based on the Landsat remote sensing data for phase, using artificial interpretation method to extract Jinzhou--huludao coastal four coastal cities space characteristic information, combined with geological statistics method, do quantitative analysis on the speed of urban expansion, the intensity of urban land fractal dimension, compactness.Results showed that, the urban expansion area in 1990--2010 was 8166 hectares, the expansion rate was 7.37%, and expansion intensity was 0.11.The fastest urban land expansion is the huludao city, and the largest extension strength is jinzhou city.The urban space of Jinzhou and Huludao is more and more scattered, and urban land boundary of Huludao city is the most complicated.The conclusion could be used as a preliminary study of urban planning, and lay the foundation for the study of the driving mechanism of urban spatial expansion and the expansion of space simulation.
