Introducing Surface Elevation Table Technique to Monitor Surface Accretion Process in Marshes in Xingkai Lake
Study on the wetland accretion process plays an important role in revealing the regional environmental evolution and wetland development process.This study first introduces surface elevation table (SET) technique to monitor surface accretion depths and calculate the surface accretion rates at 4 sites in the marshes in Xingkai Lake during the years of 2011 and 2015.The results showed that the 4 sites maintained a layer of accreted material (7.31 ±2.87) mm,(7.70±2.55) mm,(5.71±2.36) mm and (6.30± 1.69) mm thickness during the five years of the study,respectively.The 4 sites had average surface accretion rates at (1.85±0.89) mm/yr,(2.27±0.91) mrm/yr,(1.63±0.94) mrm/yr and (1.45±0.77) mm/yr respectively,and there was no significant difference among 4 sites based on the linear regression analyses.This research will provide data and technical support for the high precision study on the accretion process in the inter-annual scale in the marshes in China.
