Numerical Simulating Computation Of Self-organization Criticality For Algal Bloom In Valley Fluctuating Band And Photosynthetic Pigments Energy Transfer Mechanism

Because the algal blooms system is a water valley bio-chemical dynamical system which has the features of multi-factors coupling, multidimensional vanish-rising and self-organized criticality (SOC). The formation, eruption, spread, standing and fluctuating of algae have a complicated,non-linear and self-organized criticality relationships which are similar to the content of the water eutrophication substance.Sandpile Model(SM) is the typical example of SOC system which has the most physical meaning. SOC and SM study these systems, which are open systems with vanish-rising behavior. And the typical eutrophicated valley is just an open system with substance and energy exchange. So we can use SOC, SM, bio-chemical reaction mechanism and the monitoring data to deeply study and describe the inner-rules of Three-Gorge eutrophication and algal blooms.As the increasing understanding of eutrophication mechanism and the development of computer technology, more and more eutrophication studies focus on the mathematic modeling of eutrophication. After the systemic introduction of the mathematic modeling of eutrophication, this paper presented our studies on behaviors of algal blooms along Three-Gorge reservoir with the help of the theory of Self-Organized Criticality (SOC).According to the current decade local monitoring data such as total concentrations of nitrogen and phosphorus, water temperatures, flow velocities and light illuminations a numerical sandpile model based on self-organized criticality theory was constructed to reveal inherent dynamic mechanism of algal blooms and describe complex evolution process of alga growth in an open environmental system of water fluctuating band along riversides of the Three-Gorges valley. With the frequency-scale power law relationship we have charactered the avalanche behavior of numerical sandpile as a criterion to estimate algal bloom and predict the scales, verified also the self-organized criticality of the algal bloom system through finite size scaling analysis, and all results were consistent with the monitoring data very well. Simulating computation showed if there existed power law relationship in the sandpile model, the corresponding water fluctuating band system would appear algal bloom pollution, and absolute values of exponent of the power law were all directly proportional to scales of algal bloom.Photosynthesis efficient light absorption, transmission and conversion and control based on the microscopic mechanism of photosynthesis research are the core of the current international issues. Now it has been confirmed that the absorption of light photosynthesis transmission and transformation process is in a series of photosynthetic membranes of the photosynthetic pigment-protein complex of orderly conduct. This paper introduces the process of photosynthesis and the original key photosynthetic pigments, and then focused on the light energy absorbed by the photosynthetic pigments, and the settlement agreed to the transfer mechanism model. Through these models, the original theory expounded in the photosynthesis process of a series of photon excitons, electronics, ion transmission and conversion of the complex physical and chemical processes. Construction has been able to take the physical and chemical basis of the theoretical framework to explain algae outbreak.
