模糊综合评价在评估岩滩水库水质周年变化中的应用

用模糊综合评价方法评价岩滩水库4个类型监测区水质周年变化。结果表明,各监测区周年水质均为Ⅲ类。影响水质的主要因子是TN,TN超标倍数（WTN）分析表明,在相同水质等级（Ⅲ类）内,汉达监测区水质最好,TN超标倍数（WTN）值处于0.0960.883范围;江栋监测区水质最差,TN超标倍数（WTN）值处于0.5571.358范围。水质周年变化与大水面养殖状况关系密切,建议在大水面开展鱼类养殖、促进库区移民增收的同时,充分保护养殖水域环境,提高大水面资源综合、可持续利用水平。...

Summary:用模糊综合评价方法评价岩滩水库4个类型监测区水质周年变化。结果表明,各监测区周年水质均为Ⅲ类。影响水质的主要因子是TN,TN超标倍数（WTN）分析表明,在相同水质等级（Ⅲ类）内,汉达监测区水质最好,TN超标倍数（WTN）值处于0.0960.883范围;江栋监测区水质最差,TN超标倍数（WTN）值处于0.5571.358范围。水质周年变化与大水面养殖状况关系密切,建议在大水面开展鱼类养殖、促进库区移民增收的同时,充分保护养殖水域环境,提高大水面资源综合、可持续利用水平。

Using fuzzy evaluation the annual variation of water quality in four monitoring areas of Yantan Reservoir was evalualed. The results showed that the annual variation of water quality in Yantan reservoir was at grade Ⅲ, the main influence factor was total nitrogen（TN）, the analysis of TN exceeded multiple（WTN） indicated that at the same grade（grade Ⅲ）, the water quality of Hada monitoring area was the best, WTN ranged from 0.096 to 0.883; the water quality of Jiangdong monitoring area was the worst, the WTN ranged from 0.557 to 1.358. The annual variation of water quality had a close relationship with the condition of large aquaculture area, we should protect the water environment, improve the level of large waters resources＇ comprehensive and sustainable utilization when we developed the large aquaculture and promoted the income of immigrants in reservior area.
