摘  要：
于2015年8月对亚龙湾近岸海域进行现场监测,采用单因子指数法、有机体污染指数法、水质富营养化法对亚龙湾近岸海域环境进行评价。结果表明:2015年亚龙湾近岸海洋环境良好,海水水域溶解氧(DO)、化学需氧量(COD)、溶解无机氮(DIN)、溶解无机磷(DIP)及重金属含量较低,符合第1类海水水质标准;沉积物重金属、石油类、有机碳、硫化物含量测值存在一定的差异,但变化较小,均在第1类海洋沉积物标准要求范围内;监测海域单因子评价指数值均小于1,未出现超标现象;有机体污染指数较小,其中有65%的站点有机体污染指数(A值)小于0,35%的站位A值0-1;有机体污染水平评价多为良好;水质营养化水平程度较弱,除了个别站位出现中等营养化水平,绝大部分监测站点属于贫营养化。对比历史资料,近年来亚龙湾近岸海域海洋环境各化学要素测值存在差异但变化幅度不大,说明亚龙湾开展旅游活动对海洋生态环境未造成明显的不利影响。

摘  要：
We monitored the coastal waters of the Yalong Bay in August, 2015. And use the single factor index method, organic pollution index method and the method of water quality eutrophication to research the environment of Yalong Bay coastal waters. The results show that the environment of Yalong Bay is good in 2015. The content of DO, COD, DIN, DIP and heavy metal is low in the seawater of Yalong Bay, it meets the first kind of sea water quality standard. Although the measurement values of sediments of heavy metal, petroleum material, organic carbon and sulfide's content are different, they change very little. And they all meet the first kind of sea water quality standard. The values of single factor evaluation index are less than 1, and they are not more than the standard. The organic pollution index is low. The organism pollution factor index of 65% monitoring stations is less than zero in monitoring area. A-value of 35% monitoring stations changes from zero to one. The assessment level of organic pollution is always good.The degree of water quality eutrophication level is weak. Except that individual monitoring stations are at the medium level of eutrop hication, the vast majority of monitoring sites are at the very low level of eutrophication.Through comparing with the historical datas, each chemical factor's measured value of marine environment changes little in Yalong bay inshore coastal waters these years.These results attest that the tourism activities in the Yalong Bay don't cause obvious adverse effect to marine ecological environment.
