摘要: 近10年来，福建省地质调查研究院对陆相火山岩区填图方法进行了不断的探索与试验，特别是对福安市幅等4幅1∶50000区域地质调查项目进行全面系统的调研与总结，取得了重要进展，将火山岩区“火山地层-岩相(岩性)”双重填图法发展完善成为“火山构造-岩性岩相-火山地层”三位一体的填图方法。将该填图方法作一简单的总结，以求共同提高新一轮区调填图的质量。

Abstract: In recent ten years, Fujian Institute of Geology Survey and Research explores continually the mapping methods in the nonmarine volcanic terrain Fu'an and other three breadths 1∶50000-scale regional geological surveying item obtained important progression in mapping methods of volcanic terrain, which was developing “volcanic sequence-rock facies(lithology)” diplex mapping method into “volcanic construction-lithologic rock facies-volcanic sequence” triune mapping method in the volcanic terrain. We sum up the mapping method in order to improve the mapping quality in new round regional geological surveying together.
