大洋多金属结核开发对环境的影响

Effects of Exploitation of Oceanic Polymetallic Nodule upon Environment

首先强调了大洋多金属结核开发过程中不能忽视环境影响的研究。概述了目前环境研究的重点及趋势，并分别讨论了深海采矿过程、海面活动及岸上加工所造成的环境影响。总结归纳认为，大洋多金属结核开发对环境的影响有３个主要问题，这说法是海底采矿、采矿船的废水排放和岸上加工所产生的环境影响，其中海底采矿活动又是最为重要的影响因素。

An emphasis is put on that researches should not be neglected about effects of exploitation of oceanic polymetallic nodule upon environment. The focal points and trend of the researches being carried out are briefly described, and impacts of sea-bed mining, activities on the sea and work on land on surroundings respectively. It is concluded that the enviromental impacts are mainly resulted from submarine mining, waste water discharge of mining ships and processing onshore, of which the submarine mining is the most crucial impact on the environment.
