专业解析

The term "深海底" (shēn hǎi dǐ) refers to the deepest regions of the ocean floor, typically defined as areas below 3,000 meters in depth. In English, it is most accurately translated as the"abyssal zone" or"abyssal plain", a permanently dark and high-pressure environment devoid of sunlight. This zone is characterized by extreme conditions, including near-freezing temperatures, sparse nutrients, and unique ecosystems adapted to chemosynthesis rather than photosynthesis.

The abyssal plain constitutes over 50% of Earth's surface, making it the largest habitat on the planet. Its geological features include sediment-covered plains, hydrothermal vents, and seamounts. Organisms here, such as giant tube worms and bioluminescent fish, rely on organic debris sinking from upper ocean layers or microbial processes around volcanic vents.

Scientific studies highlight its role in carbon sequestration, as deep-sea sediments store vast amounts of organic carbon. Additionally, mineral deposits like polymetallic nodules found in these regions have sparked interest in deep-sea mining, though ecological impacts remain a concern.

For linguistic reference, authoritative dictionaries like the Oxford English Dictionary define "abyssal" as "relating to the depths of the ocean," rooted in the Greek ábyssos ("bottomless"). This aligns with the Chinese term's emphasis on profound depth and ecological isolation.

网络扩展解释

"深海底"一词可从以下几个方面详细解释：

一、基本定义深海底指海洋中水深超过200米的区域，是海洋的深水底部，覆盖地球约71%表面积，水体体积占全球总水量97%。

二、环境特征

物理条件：水温低、海床柔软且环境稳定，无阳光照射和季节性变化。
地理范围：包括太平洋、大西洋、印度洋和北冰洋等主要大洋的底部区域，通常以海底地形线为分界。

三、生物特点该区域因缺乏光合作用条件，植物种类匮乏，但栖息着大量适应高压、黑暗环境的深海动物，如管虫、深海鱼类等。

四、延伸含义在成语或文学语境中，"海底"可比喻隐藏的真相或秘密，而"深"字本身带有"程度高""距离大"的引申义，因此"深海底"也可用于形容事物被深层次隐藏的状态。
