| 中文摘要: |
| 本文基于1988—2014年的监测数据,针对象山港海洋生态环境状况,建立了象山港海洋生态环境评价的科学方法,结果表明:(1)根据象山港生物生态、水质、水动力、水团提出了三类三级评价指标体系,其中水质指标的确定综合考虑了水体中主要超标物质、长时间序列的波动及变化趋势;(2)根据东海E2断面、象山港及口门监测数据统计分析确定象山港的活性磷酸盐和无机氮的环境污染变化推荐基准年分别为1993年和1992年;结合频数分析法,象山港海域活性磷酸盐和无机氮的推荐基准值分别是0.023 mg/L和0.50 mg/L;(3)评价分级根据生态环境现状及分区衔接确定为3个等级,其中水质指标选择2011年25%、75%所对应的营养盐浓度值为分级依据;(4)评价结果表明,2011年象山港从口门至港底生态环境分别为好、较好、一般,2014年为好、较好、一般、差;与2011年相比2014年象山港2、4、5、7、8、9区的综合环境有所下降。 |

| Based on the monitoring data from 1988 to 2014, combined with the ecological environment condition of Xiangshan Bay, a scientific evaluation method of marine ecological environment in Xiangshan Bay was established.The results showed that:(1)The evaluation index system in Xiangshan Bay was composed of biology and ecology, water quality, water power and water mass. The determination of water quality index was on the comprehensive consideration of the over standard rate, fluctuation and trend.(2)The base year of phosphate and inorganic in Xiangshan bay was 1993 and 1992 by data statistical analysis from the E2 section of east sea and the mouth of Xiangshan Bay. And then combined with the frequency analysis the recommended reference values of phosphate and inorganic nitrogen in Xiangshan Bay was 0.023 mg/L and 0.50 mg/L.(3)Three evaluation classes was determined by the present ecological environment situation and the partition, while the 25% and 75% of the nutrient concentration values was chose for the classification basis.(4) The marine environment evaluation results was "perfect"、"good"、"general" or "poor" in Xiangshan Bay, which can be divided into 3-4 different areas. The comprehensive environment of 2, 4, 5, 7, 8, 9 zones in 2014 was poorer than 2011. |
