摘要

非洲城市正在经历不受控制的扩张。本文的重点是评价1972 - 2009年城市扩张对阿库雷土地利用类型的影响。利用1972年MSS、1986年Landsat Thematic™和Landsat Enhanced Thematic Mapper Plus (ETM+) 2002年和2009年从google earth网站获取的卫星图像,进行分类后对比分析,绘制了阿库雷土地利用/土地覆盖变化的空间动态,并确定了城市扩张。问卷调查也被用来确定负责Akure扩张的因素。结果表明:1972年至1986年,阿库雷市建成区面积从1.00%迅速扩大到2.46%,1986年为2.46%,2002年为3.90%,年增长率分别为10.63%和3.66%。据预测,到2022年,阿库雷的建成率将扩大到2.66%。该研究建议审查过时的1980年总体规划和发展控制机制,这些规划和机制将指导伴随着阿库雷植被损失的快速扩张。

Analysis of the Urban Expansion for the Akure, Ondo State, Nigeria
African cities are experiencing uncontrolled expansion. The focus of this paper is to evaluate the impact of urban expansion on landuse types of Akure for the period of 1972 to 2009. In analyzing the urban expansion of the city, 1972 MSS, 1986 Landsat Thematic ™ and Landsat Enhanced Thematic Mapper Plus (ETM+) images for 2002 and 2009 satellite image captured from google earth website were used in a post classification comparison analysis to map the spatial dynamics of landuse/ land cover changes and identify the urban expansion of Akure. Questionnaire was also used to determine the factors responsible for the expansion of Akure. The findings showed a rapid expansion in the built-up area of Akure from 1.00% in 1972 to 2.46% in 1986, 2.46% in 1986 to 3.90% in 2002 with an annual growth rate of 10.63% and 3.66% due to increasing population of Akure within these periods respectively. Prediction made showed that the built-up of Akure would expand to 2.66% in 2022. The study recommends review of the outdated 1980 master plan and development control mechanism that will guide the rapid expansion that had been accompanied by loss of vegetation in Akure.
