本研究利用地理空间工具和技术，研究了1990-2000年和2000-2010年期间赞比亚快速城市化的城市卢萨卡城市土地利用（urban- lu）变化的时空格局。结果表明：1990 - 2010年，我市经历了快速的城市增长，城市用地面积增长约233%；结果还表明，与1990年代相比，2000年代的城市-陆域扩张更为强烈。在空间上，城市呈现出无序的城市- lu格局，与主要道路和城市中心的格局相关联，汲取了殖民时代的遗产。卢萨卡已经成为一个高度无规划的城市，大约40%的城市代表着未规划的住宅用地，主要是非正式定居点（30%）。商业和工业用地的增长也与高密度住宅用地的增长保持一致。规划的居住用地、公共机构用地和服务用地增长缓慢。研究结果进一步揭示了非正式住区对商业、工业和规划中高密度住宅用地的空间依赖性。该研究讨论并为战略性城市规划提供了重要见解，可以控制观察到的计划外城市增长并刺激城市可持续发展。
This study examines the spatiotemporal patterns of urban land use (urban-LU) change in the rapidly urbanising city of Lusaka, Zambia, during the 1990-2000 and 2000-2010 periods, using geospatial tools and techniques. The results show that the city experienced rapid urban growth, with about a 233% increase in the total urban-LU area from 1990 - 2010. The results also show that urban-LU expansion was more intense during the 2000s than during the 1990s. Spatially, the city displays a disordered pattern of urban-LU associated with the pattern of major roads and the city centre, which draws its legacies from the colonial era. Lusaka has emerged as a highly unplanned city with approximately 40% of the city representing unplanned residential land use dominated by informal settlements (30%). The growth of commercial and industrial land use has also been consistent with high density residential land uses. The growth of planned residential, and public institutions and service land uses has been slow. The results further reveal spatial dependency of informal settlements on commercial and industrial, and planned medium to high density residential land uses. The study discusses and offers vital insights for strategic urban planning that can control the observed unplanned urban growth and stimulate sustainable urban development.
