摘要: 海南岛北部(简称琼北)广泛发育的新生代岩被,构成平面上似曲尺状,地形上呈波状起伏,一望无际的火山岩低丘台地。火山岩覆盖面积达4159.8平方公里,占本岛总面积的12.3%。琼北与隔海相望的雷州半岛同属陆间裂谷型构造,强烈的新构造运动使琼雷地区成为我国重要的新生代火山活动区域之一。琼北因火山活动持续时间更长,强度较大,火山地貌尤为发育。繁多的火山地貌类型,特异的形态,为国内所罕见,不失为我国又一"天然火山博物馆"。本文根据多年野外考察和参考有关资料,对琼北地区的火山锥及其他火山地貌试作分类,并对丰富的火山旅游资源给予粗浅的评价。

Abstract: The Cenozoic volcanic rock covers an area of 4159 km2 in north Hainan, consisting 12.3% of the total area of the island. Belonging to tectonics of the rift valley type,the north Hainan is one of the most active Cenozoic volcanic areas in China. Volcanic geomorphy is well developed as a result of long-time and intensive volcanic activities.
