【摘要】：随着我国城市化进程的不断加快,城市数量不断增加,城市规模逐步扩大,导致城市用地不断发生变化。城市用地的空间扩张愈发成为现在乃至将来土地利用变化的最主要特征和该领域研究所关注的焦点。研究城市用地扩展问题可以加深对城镇化本质的理解,进而可为城市可持续发展提供有效的决策依据,而遥感和GIS的发展无疑为研究城市用地扩展提供了重要的技术支撑。为此,全文以环泉州湾地区为例,以土地利用变化和城市用地扩展为切入点,选取2000、2005、2010年三期TM遥感影像数据为基础数据,基于GIS技术平台,采用目视解译与监督分类相结合的人机交互分类方法对环泉州湾地区遥感影像进行解译,定量地分析了环泉州湾地区2000-2010年土地利用变化、土地利用类型转换和土地利用景观格局变化。运用三期遥感影像土地利用分类结果图像和仿归一化植被指数(NDBI)方法提取环泉州湾地区建设用地图斑,在此基础上提取出环泉州湾地区城市用地图斑,并进行叠加分析,对研究区城市用地扩展的速度及强度进行定量分析,提出用地扩展综合指数模型,通过基于缓冲区和方向扇区来分析城市用地扩展的空间分异特征,分析城市扩展的空间形态变化以及探讨城市用地扩展模式。最后结合研究区的社会经济统计数据,分析了环泉州湾地区在研究时段内城市用地扩展的驱动力,为今后环泉州湾地区城市用地扩展决策提供参考依据,促进环湾城市社会经济与生态环境可持续发
[Abstract]:With the rapid development of urbanization in China, the number of cities is increasing and the scale of cities is expanding, which leads to the change of urban land use.The spatial expansion of urban land has increasingly become the most important feature of land use change and the focus of research in this field.The study of urban land expansion can deepen the understanding of the essence of urbanization and provide an effective decision basis for urban sustainable development. The development of remote sensing and GIS undoubtedly provides an important technical support for the study of urban land expansion.Therefore, this paper takes Huanzhou Bay area as an example, takes land use change and urban land expansion as the breakthrough point, selects the TM remote sensing image data of 2000.2005 and 2010 as the basic data, and based on the GIS technology platform.A human-computer interactive classification method combined with visual interpretation and supervised classification was used to interpret remote sensing images in Huanquan Bay area, and the land use changes in Huanquan Bay area from 2000 to 2010 were analyzed quantitatively.Land use type conversion and land use landscape pattern change.The land use classification results of three remote sensing images and the simulated vegetation index (NDBI) were used to extract the construction land spots in Huanquanzhou Bay area. On this basis, the urban land use map spots in Huanquan Bay area were extracted, and the superposition analysis was carried out.Based on the quantitative analysis of the speed and intensity of urban land expansion in the study area, a comprehensive exponential model of land use expansion is proposed to analyze the spatial differentiation characteristics of urban land expansion based on buffer zone and directional sector.This paper analyzes the spatial change of urban expansion and discusses the mode of urban land expansion.Finally, the driving force of urban land expansion in Huanquanzhou Bay area is analyzed according to the social and economic statistics of the study area, which provides a reference basis for the decision-making of urban land use expansion in Huanquan Bay area in the future.Promoting Sustainable Development of Social economy and Ecological Environment in Huan Wan City
