利用遥感和地理信息系统（GIS）对1987 - 2017年肯尼亚中部Kieni副县土地利用土地覆盖变化（LULCC）进行了调查。这是通过下载和处理1987年、1995年、2000年、2010年和2017年的陆地卫星图像来完成的。采用的方法有：数据识别与采集、图像处理、验证与呈现。分析了六种分类，分别是；裸地、丛林、农田、森林、草原和水体。结果表明：水体、农田和裸地的种类在30年间分别增加了314.86%、160.45%和73.18%；森林、灌木林和草地的土地利用、土地覆被类别分别减少了45.94%、38.73%和29.66%。综上所述，在1987年至2017年的30年间，研究区域的土地利用和土地覆盖发生了变化，结果表明，农田分类增加了1.5倍以上，而森林覆盖减少了约一半。
To investigate land use land cover changes (LULCC) in the Kieni sub-county in Central Kenya from 1987 to 2017, remote sensing and Geographical Information System (GIS) was used. This was done by downloading and processing landsat images of 1987, 1995, 2000, 2010 and 2017. Methods employed were, data identification and acquisition, image processing, validation and presentation. There were six classifications analysed which were; bare areas, bushlands, farmlands, forest, grasslands and waterbodies. The results showed an increase in the classes of water bodies, farmlands and bare areas by 314.86%, 160.45% and 73.18% respectively over the 30-year period. The results also showed a decrease in the land use land cover classes categories of forest, bushlands and grassland by 45.94%, 38.73% and 29.66% respectively. Therefore, in conclusion, there were land use and land cover changes in the study area over the 30-year period between 1987 and 2017 as illustrated by results that showed that farmlands classification increased by more than one and half times while forest cover was reduced by about a half.
