摘要
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人稳定期,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人攻坚克难阶段。
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 d ata fitting work for main w ater quality indicators in Taihu Lake was done as well.It was found that there was a significant improvement trend for aquatic eco-environm ent quality in Jiangsu P rovince,and the concentrations of main quality indicator all perform ance a decrease trend during the studied 10 years.The main water quality indicators in Taihu Lake decreased significantly,and the concentrations of perm anganate 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-environm ent quality in C hinese 12th five-yearplan period was less than that in 11,h five-year-plan period.The improvement for aquatic eco-environm ent quality already entered the critical phase to overcome difficulties.
