  • 摘要: 为研究宜兴滆湖地区河蟹生态养殖池塘对水环境的影响，于2017年5—10月对江苏省宜兴市高塍镇滆湖渔场3个河蟹生态养殖池塘和水源进行水质监测，并采用灰色关联分析法对水质进行评价，结果表明，整个养殖期间池塘T、DO和pH与水源差异较小，TN、NH3-N、NO2--N和NO3--N总体低于水源，TP、PO43--P和CODMn总体高于水源，池塘对水体的净化效果主要体现在对各种形式含氮化合物的吸收转化.池塘和水源水质等级在Ⅲ类以上的频率分别为76.7%和50%，主要超标指标均为TN、TP和CODMn.池塘和水源的水质排序结果表明，养殖前中期池塘水质大体优于水源，后期及起捕后劣于水源，若将养殖尾水不经处理直接排放到水源，最终汇入滆湖，会对滆湖水体造成污染.高温季节及时割去伊乐藻冠层和适当降低放养密度，可能是优化宜兴滆湖地区河蟹生态养殖模式、提高生态效益的两个方向.
    Abstract: This study aims to explore the impact of Eriocheir sinesis farming on the surrounding water environment in Gehu Lake area. Water quality monitoring has been conducted in three ponds and water source from May to October in 2017 at Gehu Fish Farm, Gaocheng Town, Yixing City, Jiangsu Province. Water quality was evaluated using the method of grey correlation analysis. The results showed that throughout the farming cycle, the differences of T, DO and pH between ponds and water source were not significant. Levels of TN, NH3-N, NO2--N and NO3--N of pond waters were generally lower than those in the water source, and levels of TP, PO43--P and CODMn of ponds were generally higher than those in the water source. Water quality could be improved in farming ponds due to the absorption and transformation of various nitrogen compounds by water plants. The frequencies of water quality grade better than the class Ⅲ in ponds and water source were 76.7% and 50% respectively. The main indicators higher than the standard were TN, TP and CODMn. Water quality of ponds was generally better than that of water source in the early and middle stages of the farming cycle, but worse than that of the water source in the later stages and after harvesting. If the pond water was discharged directly into the water source, it would eventually run into Ge Lake, which would pollute the water body of Ge Lake. We suggested that cutting off Elodea canopy regularly during the high-temperature season and reducing the stocking density as two management options to optimize the farming mode of Eriocheir sinesis in Yixing Ge Lake area and improve its ecological performance.
