柘林湾-南澳岛海洋牧场由网箱养殖区、贝类底播区、海藻养殖区和人工鱼礁区4个不同的功能区构成。根据2011年夏季（8月）海水营养盐的调查数据，分析其表层海水营养盐含量的空间分布特征，并对其污染现状进行综合评价。结果表明，氮、磷营养盐的空间分布均呈现由西北部柘林湾近岸海域向东南部海域递减的变化趋势。不同功能区中，无机氮（ DIN）和活性磷酸盐（ PO4-P）的高值出现在网箱养殖区，硅酸盐（ SiO3-Si）的高值出现在贝类底播区，人工鱼礁区的营养盐水平均较低。单因子污染指数、污染物分担率和综合污染指数评价结果也表明，海洋牧场受到DIN和PO4-P污染的程度以及富营养化程度均呈现由西北海域向东南海域递减、近岸向离岸递减的变化趋势。网箱养殖区受DIN和PO4-P污染最重，呈现严重富营养化，其次为贝类底播区，而人工鱼礁区和对比区受到的污染程度均较轻。

The marine ranching in Zhelin Bay-Nanao Island is divided into four different function areas:cage culture area,shellfish farming area,seaweed culture area and artificial reef area. Based on the survey data in that marine ranching in August of 2011,we analyzed the spatial distribution characteristics of nutrients in the surface seawater and evaluated the nutritional status. The results show that the contents of dissolved inorganic nitrogen( DIN)and active phosphate( PO4-P)decreased from the northwest of Zhelin Bay to the southeast of the investigated area. Among the four different function areas,the high-value of DIN and PO4-P occurred in the cage culture area,while the maximum content of silicate( SiO3-Si)was occurred in the shellfish framing area. Nutrient salts levels in the artificial reef area were relatively low. We assessed the sea water quality in the marine ranching by using single factor index,share rate of pollutants and comprehensive pollution index. The results suggest that the nutrient pollution trend caused by DIN and PO4-P in the marine ranching declined from the northwest to the southeast and from inshore to offshore waters. Moreover,the pollution and eutrophi-cation state in the cage culture area was most serious,followed by the shellfish farming area,while the artificial reef area and control area were found for less pollution.
