摘　　要：通过在博茨瓦纳中部区Tonota-Foley一带的找矿勘查,探讨土壤地球化学测量方法在博茨瓦纳热带干旱草原景观区的应用效果。利用该方法,在Tonota-Foley一带圈定出化探综合异常17处,通过对典型异常的查证工作,运用槽探工程,查明了异常源为方解石蛇纹岩体,说明土壤地球化学测量方法适用于博茨瓦纳中部地区的景观条件,圈定的异常准确、有效,该方法可在博茨瓦纳同类地区推广使用。The authors explained the application effect of the soil geochemical survey in the tropical arid steppe landscape area of Bot-swana,exemplified by the prospecting in Tonota-Foley, within central area of Botswana. By using this method, the authors delineated 17 geochemical composite anomalies in Tonota-Foley and found that the sources of anomalies are calcite serpentine, as evidenced by trenc-hing in the typical anomaly areas. It is shown that soil geochemical survey, which is accurate and effective in delineating anomalies, is suitable for the landscape of the central area of Botswana. This method can be extensively employed in similar landscape areas of Bot-swana.
