Abstract—The Inner Lake is a typical tide-influenced
waterfront body in Eastern China. Series of environmental
factors of the lake changed frequently and extensively due to its
location. Regulating the water exchange for an improved living
condition to restore macrophyte is very important to establish a
healthy ecosystem. A differentiation function for submerged
macrophyte restoration was proposed, and the numerical
differentiation model was established, in which the projection
pursuit theory was used to solve high-dimensional matters. The
restoration areas of Vallisneria gigantean L. in the Inner Lake
in different hydrological years were forecasted. The results
showed that the restoration regions in different typical years
varied to some extent. The main restoration areas in the three
years were similarly concentrated in the north and south parts
in the lake. It was difficult to restore the macrophytes in the
mainstream of the lake for its stronger water disturbance and
higher suspended sediment concentration.
Index Terms—Differentiation, inner lake, restoration,
