The changes of river-lake relationship have become one of the important influencing factors on water environmental quality of Poyang Lake. the influence mechanisms of river-lake relationship change on water environment were revealed according to the development and evolution of Poyang Lake and the effects of river-lake relationship change on pollution load into the lake, water quality, sediment, and plankton bloom, etc. From the perspective of biogeochemical cycles of nitrogen and phosphorus, it is revealed that the influence mechanisms of river-lake relation change on generation, transportation, transformation and degradation, as well as the distribution and partition of nitrogen and phosphorus in water and sediment. the coupling model of water quality-hydrodynamic was used to assess the influence of river-lake relation change on water quality and water hydrodynamic. the SWAT model and GIS technique were utilized to calculate the influence of river-lake relation change on input of nutrient load and that on distribution of typical wetland vegetation. the influence of river-lake relation change on algal blooms was discovered through utilizing the methods of situ observation and laboratory simulation experiment. ©, 2015, Science Press.
