为探讨附著生物的出现季节与数量，本研究自民国七十一年三月至七十二年五月於嘉义县布袋海湾之牡蛎养殖区内，每月以塑胶板做为基质，於不同地点及水深放置一、二与三个月，以采集当地之附著生物。

In this paper, two types of transport models widely used for water and salinity in soils are introduced; one is physical models, which include convection-dispersion Equation, stream tube model and HYDRUS developed by US Salinity Laboratory. At the same time, the parameter research is related to physical models. Another is system models, such as Transfer Function Model and BP-Network model. The resemblances and the differences among these modeling are compared and analyzed.
