[Study on evaluative function model of algae blooms in the representative valleys along Three-Gorges area].
Algal will turn abio-phosphate and ADP (Adenosine biphosphate) into ATP (Adenosine Triphosphate) for storing energy under enough sunlight. As environment conditions change, there will be a reversible process that ATP turns into ADP in order to release energy. Based on local monitoring data from representative valleys along the Three-Gorges valley during algae blooms, the activation energy deltaE of green alga photophosphorylation, the effective energy delta e and the integrated nutritional index TLI(sigma) in these water areas under different hydrological conditions are studied, and then the algae blooms evaluative Function F which has three parameters deltaE, delta e and TLI(sigma) has been constructed. Based on the impact degree of inner factors and environmental factors described above to algae blooms, correlative weight coefficient of deltaE, delta e and TLI(sigma) were introduced as a1 = 0.3, a2 = 0.3 and a3 = 0.4 respectively. Computing results and local monitoring data indicate that F is more reasonable, persuasible and generalizable than a single TLI(sigma) to predicate algae blooms or eutrophication in water environment.
