| 摘要: |
| 依据2009年广西桂平市东塔鱼类产卵场水质调查监测结果,选择溶解氧(DO)、高锰酸盐指数(CODMn)、总氮(TN)、总磷(TP)4个代表性指标作为评价因子,参照《地表水环境质量标准(GB 3838-2002)》,应用模糊综合评价模型对该产卵场水质状况进行综合评价。结果表明,该产卵场水质为Ⅴ类,不符合天然鱼类产卵场水质要求;重点污染物是总氮。建议有关部门开展产卵场沿江污染源治理工作,加强产卵场水域环境的管理,进一步改善水质,修复产卵场水域环境,更好地保护鱼类生物多样性。 |

| Abstract: |
| Based on the water quality monitoring results of fish reproduction spot in the river of Dongta,Guiping city,Guangxi in 2009,the dissolved oxygen (DO),permanganate index (CODMn),total nitrogen (TN) and total phosphorus (TP) 4 representative indicators were selected as evaluation factors.According to Surface Water Quality Standard (GB 3838-2002),fuzzy comprehensive evaluation model was used to evaluate the water quality of the fish reproduction spot.The results showed that the water quality of the spawning grounds was the class Ⅴ,which didn't meet the water quality requirements of natural fish spawning grounds and major pollutants are nitrogen.The relevant department should abate pollution sources and strengthen environmental management to improve the water quality,recover water environment and protect the fish biodirersity of spawning grounds along the river. |
