The effect of spatial pattern on nutrient removal is investigated using a spatial simulation model. Field data have been used from reed marshes in the Liaohe Delta, China. Four scenarios have been designed to test the effect of different landscape components on nutrient removal in the reed marsh: canal density, reed area size, reed area shrinking pattern, and pumping station position. Using the same spatial model especially designed for the study area, the efficiency of nutrient removal in each of these scenarios is simulated. The results indicate that spatial variations within each factor cause less than 10% change in the removal of total nutrients. More canals make little difference. Smaller areas are more efficient than larger ones. Some shrinkage patterns are better than others. Close proximity of the pumping station to the border of the area to be irrigated is more efficient than more distant locations. These conclusions provide theoretical support to strategic decisions for local land use planning, and contribute to the understanding of the relationship between landscape patterns and functions.
