A typical wetland in the core
area of Yancheng National Nature Reserve was chosen as study area. Using three
periods of remote sensing images in 1992, 2002 and 2011, different successional
stages of landscape have been discerned. And then by employing a
space-for-time substitution approach, related environmental factors of soil was
analyzed. The analysis results showed that the landscape types and its
successional time were the important
factors that influenced the spatial distributions of soil characteristic. The
detailed results revealed: (1) The Spartina marsh succession time was longer, more reduction
effect of soil water and salt content, more with the accumulation effect on
soil nutrients; (2) The Suaeda marsh
succession time was longer, more accumulation of soil water and salt content,
more with the weakening effect on soil nutrients; (3) The moisture, salinity of
soil decreased more and more, soil nutrient increased more and more as the grass
marsh existed longer time. This study could help us to evaluate the degradation
of wetland and the effect of wetland restoration, as well as to help us to
achieve the balance between utilization and reservation.
