| 以2006-2015年江苏省地表水监测数据为基础，统计分析了该10年间的水生态环境质量特征和趋势，并对太湖湖体主要水质指标的变化特征进行了拟合。结果表明：全省水生态环境质量在2006-2015年间总体呈改善趋势，水质主要污染指标均有不同程度下降；太湖主要水质指标下降趋势显著，高锰酸盐指数和氨氮浓度基本进入稳定期，总氮浓度也接近稳定期，太湖总磷浓度仍处于不稳定的变化期；“十二五”期间全省水生态环境改善的幅度均较“十一五”有所收窄，全省水生态环境治理进入攻坚克难阶段。 |

| Statistical analysis of variation characteristics and trend from 2006 to 2015 of aquatic eco-environment quality in Jiangsu Province were carried out based on the monitoring data of surface water. A data fitting work for main water quality indicators in Taihu Lake was done as well. It was found that there was a significant improvement trend for aquatic eco-environment quality in Jiangsu Province, and the concentrations of main quality indicator all performance a decrease trend during the studied 10 years. The main water quality indicators in Taihu Lake decreased significantly, and the concentrations of permanganate index and ammonia nitrogen entered into a stabilization period and the concentration of total nitrogen closed to a stabilization period. The phosphorous concentration in Taihu Lake was still unstable. The data also indicated that the improvement degree of aquatic eco-environment quality in Chinese 12th five-year-plan period was less than that in 11th five-year-plan period. The improvement for aquatic eco-environment quality already entered the critical phase to overcome difficulties. |
