摘要:
基于1984、1989、2001、2010年和2015年等5个时相的Landsat-5/8 TM/MSS遥感影像,利用监督分类和目视解译法对福州及其周边地区城市土地利用类型进行分类,发现这一地区在1984~2015年间经历了低速、低速、高速以及快速扩展等4个过程;城镇扩展强度指数分别为0.15、0.53、1.99和1.75,扩展强度呈现增加趋势;扩展弹性系数从0.91下降到0.75,说明城市的发展与区域的人口关系较为合理;紧凑度从0.09下降到0.06,分形维数从1.28增加至1.34,显示出该区城镇用地日益趋向复杂化趋势,福州城区及周边地区的城市扩展速率等明显受自然条件、社会经济条件以及政策规划等因素的影响较大。
Abstract:
In order to explore the development features, based on the 1984, 1989, 2001, 2010 and 2015 when five phase of Lands at TM - 5/8 / MSS remote sensing image analysis, using the method of supervised classification and visual interpretation of fuzhou city and its surrounding areas of land use types are classified, it found in fuzhou and the surrounding areas of town land area is growing fast during the study, the agricultural land area is narrow.The analysis results show that the fuzhou and surrounding areas between 1984 and 2015 experienced a low speed, low speed, high speed and rapid expansion of the four process; Urban expansion intensity index were 0.1469, 0.5343, 1.9980 and 1.7525 changes in the process; Extended elasticity coefficient decreased from 0.9080 to 0.9080, indicating the development of the city and a reasonable relationship between the population of the region; Compact degree decreased from 0.09 to 0.09, fractal dimension increased from 1.28 to 1.34, showing the towns land increasingly complicated trend. Fuzhou city and surrounding areas of the change of the urban expansion rate significantly affected by natural conditions and social economic conditions and influenced by the policy planning.
