摘要
海南岛地貌单元可分为地貌区、地貌亚区、地貌形态成因类型和微地貌4级.全岛有北部台地平原区和南部山地丘陵区2个地貌区,包括14个地貌亚区.岛内均有台地、山地、阶地、丘陵以及平原,但以台地和山地为主.考虑外营力种类和作用方向以及地貌发育历史,在海南岛内可划出5种地貌成因类型:即1)侵蚀、剥蚀构造地貌、2)剥蚀侵蚀地貌、3)河积地貌、4)海成地貌、5)火山地貌.
Geomorphologic units of Hainan Island can be divided into four classes： geomorphic regions, sub-geomorphic regions, landform-genetic types, and micro relief. They are divided into two big geomorphic regions, called a north mesa plain and a south mountains region. They contain 14 sub-regions. There are mountains, hills, platforms, terraces, and plains. However, the dominant geomorphologic landforms are mesa and mountain that covers 32.6% of the whole area of Hainan Island. Taking into consideration of the kinds and directions of exogenic forces and history of geomorphic development, five geomorphologic genetic types, including erosional and denudation structural landform, denudational and erosional landform, riverine accumulation landform, marine-built landform, and volcano landform, are delimited
