Case Study

Last Updated: 2008-07-15

The study region is the Taipei¡VTaoyuan area, which is located in northern Taiwan, includes Taipei City, Taipei County, Keelung City and Taoyuan County, and has an area of 3659 km2. Geographically, Taipei-Taoyuan area is quite diverse, ranging in altitude from sea level along the coast to about 2450 m in the mountainous region at its southern tip. Urban development dominates the Taipei Basin where rivers intersect, but reduces in the slope areas. The study region spans a range of landscape types, from urban centers in the Taipei Basin, through rural/agricultural lands, to forested slope lands. The North-South Expressways link major cities and extend along the west coast towards southern Taiwan .

Taipei-Taoyuan is an attractive region for studying urban land cover change for the following reasons. First, Taipei-Taoyuan region is the most densely populated area in Taiwan, with urbanization having occurred along the North-South transportation corridor and resulted in uncontrolled urban sprawl. Owing to the close proximity to Taiwan¡¦s major socioeconomic center, Taipei City, and the existence of major public facilities such as Taoyuan International Airport, the population of Taipei and Taoyuan Counties is growing rapidly and both areas are becoming in creasingly urban. In just 35 years (1971-2006), population of the Taipei-Taoyuan area increased 44.26%, from 6.0 to 8.7 million, making the region home to one-third of the total population of Taiwan. Second, the region has a strong agricultural history, but the agricultural landscape has rapidly been transformed from rural into industrial and urban uses owing to urban expansion. Recently, the speed of urban sprawl has been most notable in the Taipei-Taoyuan area. The statistics shows that urban areas have grown by more than 58% and agricultural areas have decreased by 160.54 km2 during 1990-2006. Finally, the region can be considered as a ¡§mixed urban-rural prototype¡¨, and thus representative of Taiwanese rural landscapes generally, which are undergoing a transformation from agricultural to post-industrial economy.
