摘　　要：目的应用模糊数学综合评价法对唐山南湖公园主要湖泊水环境质量进行评价,累积南湖水质监测数据,为制定切实可行的水环境保护计划,选择适宜的水环境保护措施提供科学依据。方法选择唐山南湖公园的3个主要湖面洗星池、养龙水和青天镜,共设13个采样点,于2014年4、5和6月各连续3 d采集浅层湖水(水面下0.5 m),测定主要污染物指标,计算模糊综合指数,对各湖面和南湖整体水质进行评价。结果总磷、总氮、氨氮、亚硝酸盐氮的超标率分别为88.89%、77.78%、33.33%和22.22%,氰化物、挥发酚、硫化物、氟离子及重金属指标均达标。南湖3个主要湖面水质合格率为55.56%,Ⅱ类和Ⅲ类水出现的频率均为11.11%,Ⅳ类水和Ⅴ类水出现的频率分别为33.33%和44.44%,Ⅰ类水质未出现。结论影响南湖整体水环境质量最大的指标为总磷、总氮,其次为氨氮。洗星池和养龙水以Ⅳ类水为主,青天镜以Ⅴ类水为主,整体来看南湖水质类别为Ⅴ类水,未达到国家标准。3个湖面的水质质量由好到差依次为养龙水、洗星池、青天镜。Objective To evaluate the quality of water environment in the South Lake Park by using fuzzy mathematics comprehensive evaluation method,cumulate water quality data,and provide scientific basis for making a feasible water protection plan and administration measures. Methods Thirteen sampling points were selected from three major lakes,including Xixing Pool,Yanglong Lake and Qingtianjing in Tangshan South Lake Park. Water samples were collected from shallow water（ 0. 5 m under water surface） of thirteen sampling points continuously for three days in each month during April,May and June in 2014. Main pollutants were measured,and then the fuzzy mathematics comprehensive index was calculated to evaluate the water quality of three major lakes and whole South Lake. Results The rate exceeded the national standard limit of total phosphorus,total nitrogen,ammonia and nitrite nitrogen was 88. 89%,77. 78%,33. 33% and 22. 22%,respectively. The concentrations of cyanide,volatile phenol,sulfide,fluoride and heavy metals were lower than the national standard limits. The qualified rate of these three lakes was 55. 56%. The frequencies of water quality reaching to class Ⅱand Ⅲ were 11. 11%,reaching to class Ⅳand Ⅴ were 33. 33% and 44. 44%,and never reaching to class Ⅰ. Conclusions The main pollutants that affected the overall water environmental quality were total phosphorus,total nitrogen and ammonia. The water quality of Xixing Pool and Yanglong Lake was in class Ⅳ,and Qingtianjing was in class Ⅴ. The overall water quality of South Lake Park was in class Ⅴ. The water quality of Yanglong Lake was the best,followed by Xixing Pool and Qingtianjing.
