急用！因为不是环境专业的，所以对一些术语感觉很难翻译，特请求帮助，谢谢了。内容如下： 通过对比分析长江干流上游入库水文站寸滩、乌江入库断面武隆、出库水文站宜昌以及入海水文站大通1956-2000年的多年平均以及2004-2005年实测水沙特征值、总磷含量，并结合室内吸附模拟实验，对三峡库区蓄水过程对悬浮物、总磷的截留效应，以及长江中下游由于悬浮物减少而引发的悬浮物对磷吸附和沉降能力的减弱进行了研究分析。研究结果表明：（1）三峡水库对泥沙的截留效应明显，蓄水之后的2004-2005年，宜昌断面泥沙截留率分别为65%和69%，年泥沙截留量分别为1.19亿吨和1.81亿吨；（2）三峡水库蓄水之后，三峡水库段对磷酸盐具有相当高的自净作用，从寸滩到宜昌，总磷平均浓度下降了37.5%；同时，长江中下游河段对总磷的自净作用消减的负荷远远低于入江的总磷负荷，从三峡库区出库断面宜昌到入海断面大通，总磷平均浓度上升了20.0%（3）一方面三峡水库蓄水对悬浮物和总磷产生高比例的截留，另一方面由于下游悬浮物减少而引发的总磷吸附沉降量的降低，结合长江中下游悬浮物对磷酸盐的室内吸附模拟实验结果，三峡水库蓄水对长江口总磷通量的影响量分别为38222.1吨（2004年）和35758.2吨（2005年）。 [ Last edited by weiwei1125 on 2009-6-13 at 21:33 ] |

| Analysis by comparing the upper reaches of the Yangtze River Hydrological Station Cuntan warehousing, storage section of Wujiang Wulong, Yichang hydrological station of the Treasury, as well as hydrological stations Chase into the sea for many years an average of years 1956-2000 and 2004-2005, the characteristics of the measured value of water and sediment, total phosphorus content, combined with adsorption indoor simulation experiments, the Three Gorges reservoir area on the storage process of suspended solids, total phosphorus retention effect, as well as middle and lower reaches of the Yangtze River as a result of suspended solids to reduce the suspended solids caused by phosphorus adsorption and sedimentation of the weakening of the ability to carry out a study analysis. The results show that: (1) of the Three Gorges Reservoir on the apparent effects of sediment retention, water storage, after 2004-2005, the Yichang section of sediment retention rates were 65% and 69%, the annual volume of sediment retained 119 million tons, respectively and 181 million tons; (2) of the Three Gorges Reservoir, the Three Gorges Reservoir on the phosphate segment with very high self-purification, from Cuntan to Yichang, the average concentration of total phosphorus decreased by 37.5%; At the same time, the middle and lower reaches of Yangtze River the role of self-purification of the total phosphorus load reduction is far lower than the total phosphorus load to the River, the Three Gorges reservoir area from the Yichang section of the Treasury to the Chase section into the sea, the average total phosphorus concentration increased by 20.0% (3) on the one hand, of the Three Gorges Reservoir suspended solids and total phosphorus retention have a high percentage of on the other hand, to reduce the suspended solids as a result of the lower reaches of the total phosphorus adsorption caused by the reduction of settlement, combined with middle and lower reaches of the Yangtze River suspended matter on phosphate adsorption indoor simulation results, with the Three Gorges Reservoir water flux of the Yangtze Delta affect the amount of total phosphorus were 38,222.1 tons (2004) and 35,758.2 tons (2005). |
