For
example, the water element is mainly converted and
transferred between the farmland and natural wetland
habitats. Thus, for conceptualizing the wetland ecohydrology
of a given region, the basic elements can be generalized
as three spheres as conceptualized in Fig. 1: the sphere of
human disturbances, the sphere of hydrological dynamics
and the response sphere of wetland natural ecosystems.
These three spheres take the water element as the core, and
the conversion of water
