| 中文摘要: |
| 根据浙江省2005—2016年经济发展主要指标与地表水环境质量监测统计数据，分析了近十年浙江省地表水环境质量变化趋势及经济发展对地表水环境治理的作用。结果表明：2005年以来，浙江省地表水环境质量呈好转趋势，Ⅰ—Ⅲ类水体显著增加，劣Ⅴ类水体显著减少，氨氮和总磷的超标率已超过化学需氧量，成为水质定类的主要指标，全省国内生产总值和环境污染治理投资的增加有效地促进了水体的水质改善。 |
| 英文摘要: |
| Based on the main economic indicators and the monitoring data of surface water environmental quality in Zhejiang Province from 2005 to 2016, the change trend of surface water environmental quality in the last decade and the effects of economic development on the surface water environmental improvement were discussed. The results showed that since 2005, surface water environmental quality in Zhejiang has been improved, water bodies at grade Ⅰto Ⅲ increased remarkably, worse than grade Ⅴ water bodies significantly decreased. Ammonia and total phosphorus whose over standard rates were larger than that of chemical oxygen demand, became the main indexes in water quality classification. The increase of GDP and investment on environmental pollution control in Zhejiang Province has effectively improved the water quality. |
