摘要
由于厦门西海域独特的地理位置,周边城市规模扩大和经济发展,使得厦门西海域承受沉重的环境负载.本文根据厦门西海域功能特点,以及在对厦门西海域水质状况分析的基础上,分析了西海域对主要排海污染物的环境承载力.西海域无机氮和无机磷平均含量基本符合四类或超四类国家海水水质标准,西海域已无无机氮和无机磷承载能力;西海域化学耗氧量、重金属(铜、铅、镉、汞和砷)和油类还存在相当的承载能力.
Xiamen western waters bears heavy environmental loads due to its unique geography position, the expanding of circumjacent city＇ s scale and the development of the city economy. According to the functions of the western waters and based on the water quality analyses, this paper analyzes the environmental capacities of some poilu- tants. The average contents of DIN and DIP are in compliance with or worse than the class Ⅳ by the national sea water quality standard, so the environmental capacities of DIN and DIP has already been zeroed. However, there are still lower carrying capacities for COD, heavy metal （Cu, Pb, Cd, Hg and As） and oils. The investigation results may provide the data for the environmental management and the control of pollution.
