4.2 Analysis of Lake Water Area Impact Factor
Poyang Lake is a classical river-connected drain lake. In terms of Fig 4
show the complex hydrological relationship of Poyang lake. This study
considered runoff, precipitation, evaporation, lakebed, and water
utilization. The groundwater does not select which exchange relationship
is too complicated to obtain. In the analysis, using inflow and net
outflow to express the influence of runoff, net outflow means the total
runoff of five rivers into the lake minus runoff from the lake estuary,
selected sediment to investigate the variation of the lakebed, and land
use to investigate the water utilization.
