东海区国家级海洋保护区环境现状及影响因素分析

Analysis on Present Environment Situation and Influencing Factors of the National Marine Reserve Area in DongHai District,China

文章根据2015—2016年东海区海洋保护区的调查研究资料,对东海区18个国家级海洋保护区环境现状进行分析。结果表明:东海区国家级海洋保护区环境状况总体较好,所有的保护区沉积物质量均符合第一类沉积物质量标准。浙江南麂列岛、福建深沪湾、浙江洞头、福建福瑶列岛、福建长乐、福建崇武、福建湄洲岛、福建厦门和城洲岛等9个保护区水质指标均符合相应的水质要求,其他保护区水质部分指标存在超标现象,超标因子主要是无机氮和活性磷酸盐,自然保护区中二者超标率均为50%,特别保护区中二者超标比率分别为50%和21.4%。水体营养物质过剩和人类活动加剧是东海区海洋保护区面临的主要环境问题。

According to the survey data of 18 marine reserves in Donghai district from 2015 to2016,the environmental status of the protected areas was analyzed.The results showed that the environmental conditions of the national marine reserves were generally good,and the sediment quality conformed to the first type of sediment quality standard.Part of the reserve quality index existed violation.The main super standard factors were inorganic nitrogen and active phosphate.The two factors in the nature reserve was 50%,in the special protected area ratio were 50% and21.4% respectively.The main environmental problems of the marine protected areas were eutrophication and the intensification of human activities in Donghai district.
