摘要
通过介绍和分析英国地质调查局(BGS)在2011年和2012年定量化评估主要矿物元素全球供应风险的方法和结果,指出由于方法的改进,第二次评估结果较第一次发生了一些明显变化;两次评估的最大共同点及亮点在于利用多源数据计算不同指标,不断完善指标体系,及时更新基础数据,以及从政治稳定性角度对管理指标的考察;但同时也存在指标权重等问题。
Through the introduction and analysis of methods and results of quantitative evaluation of supply risk of major mineral elements by British Geological Survey in 2011 and 2012 ,we pointed out that the second evaluation＇s results had significant changes compared to the first due to the improvement of method, calculating different indicators based on multi-source data, improving indictor system constantly, updating basic data timely and measuring management indicator from political stability are the greatest commonalities and highlights of the two evaluations,but there are also some disadvantages,such as indicator weight.
