【摘要】 以陆地卫星MSS和TM(ETM+)数据为主要信息源对济南市建成区近二十五年的空间扩展进行了动态监测,分5个时间段进行了分析。对济南市扩展过程对周边土地利用造成的影响,包括耕地、农村居民点和工矿、交通等其他建设用地的变化进行了定量分析。结果表明,25 a的监测期内济南市建成区面积年均扩展4.14×106m2,由1979 a的9.632×107m2增加到2004 a的1.9993×108m2。济南市建成区面积与城市总人口数、城镇居民人均年收入水平等存在着很强的相关性,是影响建成区扩展的主要驱动因子。更多还原

【Abstract】 Based on remote-sensed and GIS technology,the spatial expansion of built-up area of Jinan city in 25 years was monitored.Six images were used to extract the urban built-up area of Jinan in the past 25 years.The characteristic of the sprawl was analyzed and the increased area of the built-up area was calculated.The results show that the urban built-up area of Jinan city was 96.32 km2 in 1979 and increased to 199.93km2 in 2004,the built-up area increased by 103.61km2 during the past 25 years and expanded 4.14km2 per year.Large area of arable land,rural land,grasslands,woodlands and other land were converted to urban areas.Besides,the driving forces behind the sprawl phenomenon were analyzed from the population increase,the income level of city resident per year and the improvement of transportation aspect.更多还原
