Abstract

Abstract

The area of tidal flat in Jiangsu Province is the biggest in China,and the dynamic change of tidal flat erosion and accumulation is complicated.Spartina alterniflora is introduced artificially to the Jiangsu coast,which has significantly influenced the regional tidalflat evolution in terms of the deposition rate, sediment distribution patterns and tidal creek geometry.A ccording to surface elevations of stations and calculated sedimentation rates in different stages,the applicability of Pethick-Allen model is analysed in Jiangsu tidal salt marshes.¹³⁷Cs analysis is carried out for sediment samples from the salt marshes of Wangang to determine the sedimentation rate.A ccording to the ¹³⁷Cs analysis and the data form relative literatre,using P-A model for calculating the sedimentation rates in different stages of Jiangsu tidal flat,the results show that the original patterns of tidalflat accretion has been modified since the introduction of Spartina alterniflora,this "intruding organism" has caused rapid accretion.Surficial sediment samples were collected on typical section,and analyzed for grain size by a laser particle analyzer(Mastersizer 2000, produced by Malvern Instruments in the UK),the result shows that fine-grained sediment has been trapped by the plant,and the sediments deposited on Suaeda salsa and Spartinaang elica flats enter the upside marsh mostly through drainage creeks rather than from gently sloping tidal flats.Analysis results of remote sensing and in situ obser vations indicate that the creeks developed on the Spartina alterniflora flat have a relatively small ratio of width to depth,a relatively high density,and are more stable than other tidal flat creek systems in the region.
