摘 要 ：对以实验数据为基础建立的初步空间模型进行了验证 ,并用 Maunder和 Mauring的线性回归模型对苇田子模型进行了修正。模拟结果显示 ,辽河三角洲 8万 hm2 苇田每年灌期大约可以去除 32 0 0～ 4 0 0 0 t总氮和 80 t的活性磷 ,但这仅相当于其潜力的 1 /1 0。因此 ,运用河口湿地作为富含营养物质河水入海前的最后过滤屏障 ,对于防止近海水体的富营养化具有重要意义。

Abstract:The simulation model described in the first part of this paper is extrapolated into the whole study area in combination with the water balance data. Total nutrient input and output can be calculated from the model. Validation against field data indicated that the preliminary model is robust enough to simulate the nutrient distribution in the system (correlation coefficiency R TN = 0.717; R SRP = 0.821, higher than the significant value 0.708). But the process model used for the reed field is much...
