Abstract
Based on October 2008 ~ October 2009 the water environment monitoring data, combined
long-term monitoring data from Baoding City Environmental Monitoring Station in 1988 to
This paper researched water environment of long-term changes and the annual changes in
Baiyangdian Lake. Research the water physical and chemical characteristics of some lakes
district of Baiyangdian in the angle of physical indicators, chemical indicators, biological
indicators, temporal division and main-control factors. Discribe the variation of nutrient
concentrations in a long-term. Discussed water environment on the overall spatial and temporal
changes in Baiyangdian lake, and analyzed the differences of water environment of different
areas in Baiyangdian lake in apparent phenomenon, nutrient loading, the master factors. The
result showing that: l factors of lakes in the whole range of Baiyangdian were larger difference in
horizontal distribution. The characteristic of water environment in Different region is different.
Beyond the nutrient limitate the growth of phytoplankton in several different regions in
Baiyangdian, may be there are some other limitatefactors. Pollutants is the most important
factors which affect the water environment in Baiyangdian lake. Throw the ponent
analysis,the priority pollutant anic pollutants then total nitrogen and total phosphorous. The
growth of algae may be not the most important factor.
Throw the ecological investigation about phytoplankton and aquatic plant, we described the
position, population, spatial distribution and historical situation. The result shows
that blue green microalgae is the dominant population of algae population in Baiyangdian lake,
and the green algae has the most species and the blue algae has the most biomass. The
biodiversity of phytoplankton is decreasing. The biomass of phytoplank
