摘要

博戈索-普雷斯泰地区的采矿活动已经存在了一个多世纪。对黄金的高需求导致了该地区采矿活动的密集,并导致了土地利用的变化。本研究评估了由于采矿而发生土地利用变化的Bogoso-Prestea黄金租赁区总面积为4 379.93公顷,方法是对20年期间的土地利用流量进行估算和分析。1986 - 2006。研究结果表明,矿区土地覆盖面积从1986年的4.69 ha增加到2006年的530.84 ha,占研究面积的12.1%。与1986年的0.41%相比,2006年的定居点增加到4.95%,这表明主要由于采矿而发生了重大的农村迁移。农业用地从1986年的97.8%下降到2006年的82.7%。该研究还显示,1996年至2006年期间,由于采矿造成的土地利用仅增加了0.67%,如果这种趋势继续下去,那么在2006年至2016年期间,由于采矿造成的土地利用可能不会带来任何显着的增长。

Land Use Changes within the Bogoso-Prestea Gold Concession, South West Ghana
Mining activities have existed in the Bogoso-Prestea area for over a century. The high demand for gold has led to intense mining activities in the area and has resulted in land use changes. This study evaluated a total area of 4 379.93 ha within the Bogoso-Prestea Gold Concession that has experienced land use change due to mining using estimation of areas and analysis of land use flows over a period of twenty years ie.1986 - 2006. Results from the study revealed that mining increased in land coverage from 4.69 ha in 1986 to 530.84 ha in 2006, an increase to 12.1% of the study area. Settlements increased to 4.95% in 2006 as compared to 0.41% in 1986, showing a significant rural migration primarily due to mining. Agricultural land use reduced from 97.8% in 1986 to 82.7% in 2006. The study also revealed that land use due to mining increased by only 0.67 % between 1996 and 2006 and if this trend continues, then land use due to mining under the prevailing conditions might not introduce any significant increment between 2006 and 2016.
