摘　　要：矿产实物地质资料的筛选分级是实物地质资料采集、收藏的必要环节。本文在前人研究的基础上,引入模糊综合评价法,以地质特征、成矿背景和经济特征3类8项为评判因素,建立矿产实物地质资料的筛选分级评判模型。同时,以我国典型锡矿床为例,根据锡矿床的成矿背景、成矿区(带)、成矿时代、成因类型等资源分布特征,采用模糊综合评价法对锡矿实物地质资料进行筛选分级。结果表明,利用模糊综合评价法进行筛选分级是一种较为有效的手段。Resource distribution characteristics are considered as main factors for mineral physical geological data screening.In this paper,with comprehensive consideration of influence of various factors on the physical geological data screening,comprehensively fuzzy evaluation method is introduced on the basis of predecessors＇ research.Furthermore,the principle of screening classification for mineral physical geological data is established by the evaluation factors which include 8items of 3categories such as geological characteristics,metallogenic background and economic characteristics.Meanwhile,taking an example of China tin deposit,we selected and classified typical Chinese tin deposits according to the screening and grading principle by systematically analysis of resource distribution characteristics such as the metallogenic background,metallogenic zones（belts）,metallogenic epoch,genetic types.Results showed that,fuzzy evaluation is a relatively more effective method for classified screening due to the great fuzziness of the evaluation factors themselves on the tin physical geological data.
