| 中文摘要: |
| 滴水湖的水源大治河水质较差, 总体为V类。 滴水湖生态系统脆弱, 水体已呈富营养化,2006 年— 2008年连续3年的湖水年平均富营养化指数 (TLI) 均超过了 70, 透明度呈逐年下降趋势, 氮、磷是滴水湖污染最重要的因素。据此, 提出了“立法先行、加强监管、污染控制、生态修复、硬件保障、科技创新 ”的滴水湖水质保护思路。 |

Theecosystem inthe DishuiLake wasweak and eutrophicaition had been confirmed. Theannualaverageofcom prehensive nutritionalstatueindex (TL I) exceeded 70in 2006 to 2008 with the decreasingtransparency. Nitro gen and Phosphoruscontributed alottothepollution ofthe DishuiLake.
