Abstracts

Urban sprawl is an international phenomenon happening principally in quickly developing areas. A study on the spatiotemporal features of urban sprawl is useful for the sustainable land management, landscape and urban land planning. The present research explores the trends, types and changes of landscape of urban sprawl in the context of a rapid urbanization process in Pleiku city and in the Central Highland of Viet Nam from 2000 to 2019. The results show the expansion of the Pleiku city has witnessed a fluctuation in its land uses through two decades. The rate of land use in residential areas has been increasing by 0.22 percent, infrastructures (0.61 percent), and other land (0.41 percent). This assertion is further supported by the rapid reduction of the vacant land (1.14 percent) and agriculture land (0.21%). Moreover, three types of urban sprawl are distinguished by analyzing covered urban area maps from the analysis of Satellite data images and current land use maps. Firstly, it is the outlying type with the area of 3.97 km2 , almost 62.72 percent of the total newly increased urban area. Secondly, the area of the infilling type is 1.11 km2 , which makes up 17.54 percent, and the figure for the edge-expansion area is 1.25 km2 , accounting for 19.75% of the total urban sprawl area. Studying trends and types of urban sprawl are useful to manage and properly allocate for sustainable land resource as well as urban land use planning.
