【摘要】 为定量化探索环泉州湾地区不同时期城市化格局演变,以Landsat TM/ETM遥感影像为数据源,从建设用地扩展速度、扩展强度、时空分布特征、建设用地转移、扩展驱动力等5个方面分析了泉州市中心城区1995—2010年建设用地的变化情况,并结合自然环境和社会经济数据分析其建设用地变化的自然和人文驱动力。研究结果表明:(1)泉州市中心城区建设用地主要集中分布于原泉州城区、惠安县和晋江市,并呈现出以泉州湾为中心,沿着晋江、洛阳江为发展轴线,环湾、向湾扩展的空间动态格局;(2)1995—2010年期间泉州市中心城区建设用地呈现逐年增长的趋势,其扩展速度主要分为1995—2005年的较高速发展阶段和2005—2010年的较低速发展阶段;(3)1995—2010年间新增建设用地的最大来源为耕地,次要来源为园地和林地;(4)自然因素和社会因素共同驱动着泉州市中心城区建设用地的扩展,地形、人口和经济增长、政策是其主要的驱动力因素。更多还原

【Abstract】 Based on Landsat TM/ETM imagery and statistic data,the quantitative research has been undertaken to explore the dynamic changes of the urbanization patterns,the construction land expansion from 1995 to 2010and its natural and cultural driving force in Quanzhou urban area using five determinants:expansion speed,expansion intensity,spatial and temporal distribution,land use changes and expansion drives etc. The results showed that:(1)The urban construction land in Quanzhou City is mainly distributed in the old Quanzhou City,Huian County and Jinjiang City,which expanded along the development axis of Luoyang River and Jingjiang River;(2)The urban construction land in Quanzhou City grew gradually during period between 1995and 2010,which could be divided into two phases:the rapid development between 1995and 2005,and slow development between 2005and 2010;(3)The new built-up land was mainly converted from cropland with some from orchard and forest;(4)Physical and social factors such as population and topography economic growth,policy play important roles in the expansion of construction land in urban area of Quanzhou City.更多还原
