The Construction and Analysis of Eutrophication Model for Caohai of Dianchi Lake

Abstract

The aquatic ecosystem of lake is a complex open systems, this study that is based on the principles of maximum flux selects Caohai as the object, we apply complex systems analysis to construct eutropication model which is suitable for local conditions and select a larger time scale and control parameters to simulate the eutrophication status to find out the main factors and to put forward reasonable proposals for giving out optimal control techniques. This model can be expanded in time scale, spatial scale and the number of parameters, while the difficulty of calculation and analysis will not be increased. The trend and influencing factors of the system will be got at the same time.

“…Many studies focused on fertilization and quality of soil, water, and sediment have been reported (Lv et al, 2011;Mao et al, 2011;Shi et al, 2011;Yang et al, 2010). For the key source of agricultural pollution, many studies have used models to estimate the actual circumstances of NPS pollution (Wu et al, 2012;Li et al, 2012;Shi et al, 2005).…”
