The Study on Soil Seed Bank between Different Land-Use Types of Wetlands in Tianjin Binhai New Area

Abstract:

In order to study the characteristic of soil seed bank in saline wetlands,samples from different land-use types of wetlands were selected.After the germination test,the results showed that the reserves of SSB in the four plots are huge,but the species composition is uncomplicated,the germinated seedlings are all coastal indicating halophytes.The differences between the four plots are obvious, P-value is almost less than 0.05.Artificial landscape wetlands have the largest variance coefficient.Compared with artificial wetlands,natural conservation wetlands show unique characteristic,it has the highest species richness,it has the stablest vegetation community structure,but the density of SSB is lowest for the low interference.Natural conservation wetlands have played important role in maintaining biodiversity.Therefore, the wetland ecosystem services should be fully taken into consideration when using wetlands.Appropriate protection of wetlands are needed,for it can helps to improve the ability of SSB in vegetation recovery.
