为保护磷矿资源,优化利用磷矿资源,以中国、美国、摩洛哥三个产磷大国为研究对象,分别从国家、行业和企业三个层面,选取了磷矿基础储量、矿产平均品位、矿产集中度以及开采成本等10能个反应磷矿资源开采优势的指标,通过综合层次分析法(AHP)得到各指标权重向量,建立了磷矿开采优势指标的综合评判模型,利用逼近理想解排序法(TOPSIS)计算各国磷矿资源开采的优势.计算结果表明,中国、美国、摩洛哥三国基于磷矿开采指标的综合优势度分别为27.1%,41.7%,79.8%,从而确定摩洛哥磷矿资源开采水平最有优势.该评价方法结果合理、客观和实用,为各国的各种资源开采及资源保护提供有利的依据.

In order to protect the phosphate rock resources, it is important to optimize their usage. With the phosphorus productions in China, the United States and Morocco as examples, in three aspects including the country, the industry and the enterprise, this paper select ten indices reflecting the phosphate rock resource exploitation levels, including the phosphate rock foundation reserves, the average mineral taste, the mineral concentration and the mining cost, through the complex Analytic Hierarchy Process (AHP) to obtain the index weight vector, so as to establish a phosphate rock mining index comprehensive evaluation model, and using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to calculate the phosphate rock resource exploitation advantages for respective countries. It is shown that the phosphate production indices of China, the United States and Morocco based on the comprehensive dominance analysis are, respectively, 27.1%, 41.7% and 79.8%, thereby, the phosphate rock resource exploitation level of Morocco is the highest. This evaluation method result is reasonable and objective and practical, and can serve as a basis for the exploitation and protection of various resources.
