Study on Soil Seed Bank in Saline-Alkali Wetlands of Tianjin Binhai New Area

Abstract:

Field survey and laboratory experiment were conducted to study the characteristics of soil seed banks (SSBs) in typical Saline-alkali wetlands in Tianjin Binhai New Area. The composition, diversity and temporal and spatial distribution of SSBs in three sampling plots were analyzed. The results show that there are 26 species in the SSBs, with species density 6809~30644 grains/m2 and ecological dominance at 0.51~0.81. The diversity index show a relatively low value - the highest Shannon-Wener value is 1.78. The similarity coefficients between SSB and aboveground vegetation are low as well, the lowest value is 0.21. Vertical distribution demonstrates significantly obvious condition with 0-5cm layer having the most species.
