【摘要】 本文通过解译多时相南昌市遥感影像,分析了28年间南昌市主要建成区扩展的时空特点,并对其驱动力进行了探讨。南昌市主要建成区的用地扩展目前处于快速增长阶段,扩展过程中分别受到了交通线和赣江的引导作用和限制作用,并且以占用耕地为主。人口、工业发展、利用外资以及政策等方面的因素构成了南昌市主要建成区用地扩展的软环境影响因子,交通区位、自然条件等硬件条件也不同程度地影响着主要建成区的扩展方向。更多还原

【Abstract】 Urban land use sprawl,as a form of urbanization,can reflect the development of a city to a certain degree. By interpreting remote sensing images of 1976,1989,1995,1998,1999,2000 and 2004,this paper analyses the spatial and temporal characteristics of the area changes of the major built-up area in Nanchang. In addition,the driving forces for its urban land use sprawl are discussed. It is found,temporally,the course of the urban land use sprawl can be divided into three stages of steady increase (1976～1995),slow growth(1995～1998) and speedy development(1998～2004). Spatially,the sprawl in the main built-up area of Nanchang was inducted by transport condition and was restricted by the Ganjiang River. The farming area was influenced mostly by the urban land sprawl. Besides,as there are Ganjiang River beside of the Nangchang city and many lakes inside and outside of it,the phenomenon that the waters area was taken up was also distinct. Population,industrial development,use of foreign investment and policy constitute the soft-environmental factors impacting the urban land sprawl. According to the research on industrial development in central part of China,Nangchang is in its industrialization intermediate stage. Hence,the urban land use sprawl of it would last a long time. Besides,the orientation of the sprawl was affected by where the city is locatesd according to the transport and the natural conditions to varying degrees.更多还原
