海底洞穴是一种珍贵的自然资源。诲底原生洞穴由于海底的冲刷、崩塌和泥沙淤积,大都荡然无存。现存为数不多的海底洞穴,大都与陆地有关系,或是陆地下沉将地面洞穴带到水下,或是海平面上升将地面洞穴淹没,或是海浪冲蚀海岸掏出深邃的海蚀穴。海底洞穴既有游览价值,并为研究地壳变化、海水位置和人文考古诸方面提供了重要信息。 Seabed caves are a precious natural resource. End of the original cave due to the erosion of the sea floor, collapse and sedimentation, mostly gone. The few existing submarine caves, mostly related to land, or land submerged ground caves under water, or the sea level rise will be buried in the ground caves, or surf washed out deep sea abyss. Seabed caves have both excursion value and provide important information for studying crustal changes, seawater location and human archeology.
