| 摘要: |
| 入湖河流是外源氮磷输入湖泊的主要途径，是湖泊外源输入控制的关键中间环节.本文主要开展我国一些典型湖泊及其主要入湖河流总氮、总磷浓度对比研究，结合入湖河流氮磷输入对湖体营养水平和富营养化程度的影响分析，初步探讨我国入湖河流与湖体氮磷水质协同控制的必要性和途径.结果表明，目前入湖河流氮磷水平仍然是我国一些典型湖泊水体氮磷水平和富营养化程度的重要影响因素之一；单纯依靠入湖河流氮磷协同控制已经无法较好地实现我国一些湖泊氮磷水平达到Ⅲ类及以下水平和中营养化水平及以下，建议结合内源控制、生态修复等综合治理；除了入湖河流氮磷水质，水量也是湖泊水体氮磷水平和富营养化程度的重要因素之一.进一步结合国际上入湖河流和湖泊氮磷协同控制，以及《地表水环境质量标准》（GB 3838—2002）和相关配套政策、措施等，最终提出我国入湖河流与湖体氮磷协同控制政策建议，以期为富营养化湖泊外源氮磷输入控制，湖泊内源治理和生态修复有效开展等提供支撑和依据. |

| Abstract: |
| Inflow rivers is the main way for exogenous nitrogen and phosphorus input to lakes, which is also the key transition zone to control the external sources of lakes. Comparative analysis of total nitrogen (TN) and total phosphorus (TP) concentrations of typical lakes and their main inflow rivers from different regions of China was carried out. Based on these analyses, the influence of nitrogen and phosphorus input by the main inflow rivers on the eutrophication of lakes was discussed. Finally, the collaborative control of nutrients of water (TN and TP) between lakes and their inflow rivers was also discussed. Results showed that the exogenous input of TN and TP still had a significant effect on the TN, TP and trophic status index (TSI) of the lakes in China during the 13th Five-Year Plan period. Water quality could not reach class Ⅲ and maintain mesotrophic status for some lakes in China only by collaborative control of nitrogen and phosphorus between lakes and their inflow rivers. Control of internal load and ecological restoration should also be comprehensively applied to the eutrophication governance of lakes in China. Additionally, the water quality (TN and TP concentrations) and water volume of inflow rivers have jointly affected on the TN and TP concentrations and TSI of the lake in China. Based on the measures, regulations and laws from other developed countries, also combined with the present situation of water quality of lakes and their inflow rivers, policy and proposal about collaborative control on nitrogen and phosphorus of lakes and their inflow rivers was proposed. This research would support the control of exogenous nitrogen and phosphorus and ecological restoration for eutrophic lakes in China. |
