摘　　要：文章在充分借鉴和应用国内外砂岩型铀矿的成矿理论、成果认识的基础上,通过对中国构造地质背景分析和成矿规律总结,厘定出8条砂岩型铀矿的成矿要素和12种预测类型(矿床式)。同时,采用固体矿产矿床模型综合地质信息预测技术,全过程在GIS平台上圈定了预测区88片、预测靶区709片;采用修正体积法估算资源量,对全国砂岩型铀矿作出全面、客观评价,为今后找矿战略部署和战略选区提供科学依据。By referring and applying metallogenic theory and results at home and broad,8 mineralization elements and 12 predictive（deposit） model was summarized for sandstone-hosted uranium deposit in China.Geological information integration and deposit model method and GIS technology were adopted in the whole evaluating process,88 prediction areas and 709 target districts were delineated,and their resource potential was estimated with modified volume method.The evaluation can be regarded a general and objective assessment to national wide uranium resources and has provided scientific criteria for the strategic deploy and target screen of future uranium exploration.
