This paper describes the process of urbanization and land use change in the urban ecosystems of the National Capital Region (NCR) of Delhi, India. Two types of land use change are considered-from natural to urban and from agricultural to urban. Both types are explained in terms of economic variables known to be drivers of change. A panel data method was used, and economic variables were combined with GIS-based information on land use change during 1986-2004 for 11 administrative units of the NCR. The results suggest that investment in the construction sector plays a major role in converting the land from natural to urban areas, while differences in land productivity seems to be the major driver for change from agricultural to urban uses.
本文描述了印度德里国家首都辖区(NCR)城市生态系统中的城市化进程和土地利用变化。考虑了两种类型的土地利用变化——从自然用地转变为城市用地,以及从农业用地转变为城市用地。这两种类型的变化均依据已知的作为变化驱动因素的经济变量进行解释。采用了面板数据方法,并将经济变量与基于地理信息系统(GIS)的1986 - 2004年期间NCR 11个行政单位土地利用变化信息相结合。结果表明,建筑部门的投资在将土地从自然用地转变为城市用地方面发挥着主要作用,而土地生产力的差异似乎是从农业用地转变为城市用地的主要驱动因素。
