  pollution by water
There are many lakes in Florida, but this was the only lake which suffered pollution by water discharge from a nearby agricultural chemical plant.
      


The paper made a research on the mean water recycling in construction with examples. It is pointed that mean water can not only reduce environmental pollution by water but also provide an approach to releasing the shortage of water in city.\;

Water depth,an important hydrological factor in shallow lake,has great influence on hydrodynamics,ecological and chemical processes.Based on the field observations from 1993 to 2002,we perform correlative analyses and establish the relation regression equations water depth to total nitrogen,total phosphorus,and chlorophyll(Chla) a in seven subareas in Taihu Lake.The changes in water depth are found to have more significant influence on the concentrations of nitrogen and phosphorus in Meiliang Bay than in other...

Water depth,an important hydrological factor in shallow lake,has great influence on hydrodynamics,ecological and chemical processes.Based on the field observations from 1993 to 2002,we perform correlative analyses and establish the relation regression equations water depth to total nitrogen,total phosphorus,and chlorophyll(Chla) a in seven subareas in Taihu Lake.The changes in water depth are found to have more significant influence on the concentrations of nitrogen and phosphorus in Meiliang Bay than in other subareas,but the influence on the Chla concentration is not apparent,either in heavily polluted or better water quality subareas.the prominent effect of water depth on the concentrations of the total nitrogen and the total phosphorus in partial area of Taihu Lake suggests a feasible approach to reducing water pollution by water level regulation.

水深作为重要的湖泊水文因子,对湖泊水动力过程、化学过程和生态过程具有重要的影响。通过对1993-2002年太湖水深水质实测资料的回归分析,建立了太湖7个分区的水深与总氮、总磷、叶绿素a浓度的回归方程。结果表明,叶绿素a浓度对水深变化的响应并不显著。一般情况下,水深变化对营养盐浓度的影响不显著,但在特定的湖区,如梅梁湾,水深变化对营养盐浓度的影响显著。鉴于水深变化可以对太湖局部区域的水环境具有显著的影响,因此存在通过太湖流域水利工程的联合运行,人为调控特定湖区水深,在一定程度上改善水质的可能性。
