摘　　要：近年来三亚滨海旅游发展迅速，给近岸海洋环境带来了负面影响。为比较三亚旅游旺季，不同滨海旅游活动海域的水质状况，于2013年1—4月对亚龙湾不同滨海活动海域水体中的pH值、溶解氧、亚硝酸盐、磷酸盐、总磷和化学需氧量进行了测定和分析。结果表明，溶解氧含量为6．3～7．4mg／L，其中，参照点〉游泳区〉生活区外围〉快艇游弋区（P〉0.05）；亚硝酸盐含量为0．0038～0．0057mL／L，其中，快艇游弋区〉游泳区〉生活区外围〉参照点，且快艇游弋区显著高于参照点（P〈0．05）；磷酸盐和总磷含量分别为0．0075～0．0127mL／L和0．0114—0．0627mL／L，其中，快艇游弋区〉生活区外围〉游泳区〉参照点，且快艇游弋区显著高于游泳区和参照点（P〈0．05）；化学需氧量含量为0．48～1．28mL／L，其中，生活区外围〉快艇游弋区〉游泳区〉参照点（P〉0.05）。结论：在旅游旺季，亚龙湾海域水体水质整体上符合Ⅰ类海水水质标准，但是各种滨海旅游活动对其近岸水体水质产生了不同程度的影响，使得旅游旺季某些海域水体在个别月份达到了Ⅱ类水质标准。对近岸水体水质影响最大的是快艇游弋活动，其次为沿岸酒店和宾馆的住宿活动。The coastal tourism in Sanya city has developed in recent years, and coastal waters environment was affected. Some water quality parameters of pit, dissolved oxygen, nitrite, phosphates, total phosphorus and chemical oxygen demand were measured for evaluating the water quality affected by different coastal tourism activities from January to April in 2013 in Yalong Bay. Results showed as followed： concentration range of dissolved oxygen was 6.3-7.4 mg/L and the comparison of that was control area〉swimming area〉living area〉speed-boat cruising area （P〉0.05）.Concentration range of nitrite was 0.003 8-0.005 7 mL/L and comparison of that was speed-boat cruising area 〉swimming area 〉living area〉control area,furthermore ,there was significant difference for the concentration of nitrite between speed-boat area and controlling area（P〈0.05 ）. Concentration ranges of phosphates and total phosphorus were 0.007 5-0.012 7 mL/L and 0.011 4-0.062 7 mL/L respectively, and the comparison of that was speed-boat cruising area 〉 living area 〉swimming area 〉control area,in addition ,concentration of both was higher significantly in speed-boat cruising area than that in controlling area and swimming area （P〈0.05）.Concentration range of chemical oxygen demand was 0.48-1.28 mL/L and the comparison of that was living area〉speed-boat cruising area〉swimming area〉control area （P〉0.05）.Conclusions were as followed： water quality of Yalong Bay was accordance with Ⅰ water quality standards overall in tourist rush season, but meets Ⅱ water quality standards in specific months because of the impact of different coastal tourist activities. Activities of speed-boat cruising and living area had more influence than other coastal tourist activities in coastal area of Yalong Bay in tourism rush season.
