为探寻中小城市的可持续发展,借鉴沿海经济发达地区的经验,选择丽江及厦门作为研究对象,基于3个时相的TM/ETM+遥感影像数据,在遥感与地理信息系统技术支持下,研究了厦门市和丽江盆地在城市化过程中的景观格局演变。结果表明:1987～2007年厦门市景观格局演变明显,建设用地大幅度增加,从1987年的67.9km2增加到2007年的284.2km2,而耕地面积则从1987年的729.0km2减少到2007年的442.7km2。1989～2006年丽江盆地建设用地从1989年的11.40km2增加到2006年的25.39km2,耕地面积从1989年的137.48km2增加到2000年的154.72km2,2006年又降到146km2,先升后降,呈明显波动。两个城市扩展的途径类似:主要通过侵蚀耕地为主要特征。景观格局演变对区域水环境质量影响较大,对旅游业的影响较小。
In order to explore the sustainable development of small and medium-sized cities, learn from the experience of coastal economically developed areas and select Lijiang and Xiamen as the research objects, based on TM / ETM + remote sensing image data of three phases, with the support of remote sensing and geographic information system Landscape Pattern Evolution of Xiamen City and Lijiang Basin in the Process of Urbanization. The results show that the landscape pattern of Xiamen City evolved significantly from 1987 to 2007, with a substantial increase of construction land, from 67.9km2 in 1987 to 284.2km2 in 2007, while the cultivated area decreased from 729.0km2 in 1987 to 442.7 in 2007 km2.1989 ~ The land for construction in the Lijiang Basin increased from 11.40km2 in 1989 to 25.39km2 in 2006. The area of arable land increased from 137.48km2 in 1989 to 154.72km2 in 2000 and dropped to 146km2 in 2006, Drop, showed significant fluctuations. The way the two cities expanded was similar: the main feature was the erosion of arable land. The evolution of landscape pattern has a great impact on the quality of regional water environment and has less impact on tourism.
