摘　　要：以矿产系统勘查为目的,提出了"多目标矿产预测评价"新理念。根据矿产勘查不同阶段和不同比例尺的任务要求,将多目标矿产预测评价分为:成矿区带、矿区(带)、矿田、矿床和矿体共五个尺度。较系统地探讨了不同尺度下多目标矿产预测评价的基本特征、目的任务与研究内容。在"求异"和"创新"思维指导下,把地质异常、成矿多样性及成矿谱系的联合分析研究作为矿产预测评价的切入点,初步构建了从求异到求序的"三联式"多目标矿产预测评价的理论框架与方法基础,并进一步探讨了多目标矿产预测评价中"综合预测、系统勘查、优化评价"基本准则的深刻内涵。In this paper, with the purpose of systematic mineral prospecting, the new argument of 'multitarget minerals prediction and assessment' is put forward. Based on assignments and requirements in different stages and scales of mineral prospecting, 'multitarget minerals prediction and assessment' is classified into 5 kinds: multitarget minerals predictions and assessments of mineralization areas, oreforming belts, ore fields, ore deposits and ore bodies. The basic characteristics, assignments and contents of different scales of multitarget minerals predictions and assessments are systematically discussed. The 'threecomponent' minerals prediction is a new theory and approach of minerals prospecting by the synthetic combination and comprehensive studies of geologic anomaly, mineralization diversity and ore deposit spectrum. Based on the theory of the 'threecomponent' minerals prediction, the theoretical frame and method basis of the 'threecomponent' multitarget minerals prediction and assessment are preliminarily established. Furthermore, the basic rules such as synthetic prediction, systematic prospecting and optimized assessment are discussed on the multitarget minerals prediction and assessment.
