In this study, a new modeling method based on metasynthesis is proposed from the macro and micro levels. And the system analysis and design agent-oriented based on POMDP are provided in the same time. Finally, the two case studies are given and the experimental results have shown efficiency and rationality of this modeling method. Under greenhouse conditions, rice was taken as test object and the interactive effects of selenium and mercury in rice seedlings grown in solution culture were researched by the use of quadratic-orthogonal-rotation-combination design. The results showed that low mercury concentration (<30 µg/L) promoted selenium absorption in rice roots and shoots, which may be associated with selenium’s favorable effect on plant. Higher mercury concentration (>30 µg/ L) reduced selenium accumulation in rice roots and stems, as well as the transfer of selenium to the rice shoot. When the mercury concentration was fixed at 100 µg/L, Se in the growth medium significantly reduced Hg accumulation in the roots and the effect of Se on Hg accumulation in shoots displayed a similar pattern. However, with the increase of selenium concentration of the solution, the Hg transfer coefficient from the root to the shoot remained unchanged.
