| 摘要: |
| 广东省水库水环境质量调查评价结果表明:广东省水库水质总体较好,但不同程度地发生了富营养化;在汛期,被评价的132座水库中中营养型水库111座,中富营养型水库12座,富营养化水库2座;非汛期,中营养型水库111座,中富营养型水库11座,富营养化水库1座.造成水库富营养化的主要原因是面污染的日益加剧、城市污水排放量的激增、水土流失造成水库泥沙淤积严重、水库蓄水量减少等.水库的富营养化影响了其使用功能.为恢复富营养水库的使用功能,其对策主要是减少面污染物排放量、提高污水处理率、加强水土流失的治理、清除淤泥等. |

| Abstract: |
| The investigations and evaluation on the water quality and eutrophication status of 132 reservoirs in Guangdong province reveal that the water quality is good in genera) while a majority of the reservoire are in mesotropher to eulropher status. The major factors causing reservoir eutrophication are more serious non-point sources pollution, rapid increase in sewage discharging, reservoir sedimentation resulting from soil erosion and decrease in reservoir storage. The countermeasures against reservoir eutrophication include reducing non-point sources pollutant, raising the rate of sewage treatment, controlling soil erosion, increasing reservoir storage and removing algae. |
