摘要
采用2002年丽江城区的Landsat7 ETM遥感影像(校正后)和2010年10月28日Landsat7 ETM卫星遥感影像(待校正),运用RS和GIS相结合的技术,对丽江市建成区扩展状况进行研究,并结合相关资料分析丽江市建成区的扩张特点以及驱动力。结果表明,2002~2010年丽江市建成区由3 970.92 hm^2扩展到6 680.79 hm^2,平均年增长面积为338.73 hm^2。丽江城市建成区在方位上的扩展特征为沿原中心城区边缘扩展,向西北、正南和东南方向的扩展较为明显,正东、正西和东北方向的扩展较为缓慢。这些变化主要是受人口、经济发展、自然环境、城市规划与政策、旅游发展等因素影响。
In this paper,adopting Landsat7 ETM remote sensing images of Lijiang City in 2002（ after correction） and October 28,2010 Landsat7 ETM satellite remote sensing image（ after correction）,using remote sensing and GIS technology,and combined with some relevant information,the built-up area expansion characteristics and driving forces in Lijiang City were analyzed. The results show that,the urban built-up area of Lijiang expanding from 3 970. 92 hectares in 2002 to 6 680. 79 hectares in 2010,the average annual growth area of 338. 73 hectares. The urban built-up area of Lijiang in the range of the diffusion along the edge of the city centre,to expand the northwest,south and southeast of the more obvious,and extended east,west and northeast direction slowly. These changes were mainly affected by population,economic development and natural environment,urban planning and policy,tourism development and other factors.
