Title: Effect of Biology Sand Barriers on Soil Seed Bank in Horqin Sandy Land
Abstract: Species,density and species diversity of soil seed bank have been studied in four different experimental sites with vegetation sandy barriers in different year in Horqin Sandy Land.Some conclusions can be drawn :(1) Number of species in 7 and 5 years are more than 3 years after jamming.If no jamming,no species exist in biggish mobile sandy dune.(2) There are maximum density of seed in soil seed bank after many-year restoration.(3) The variational trend of each experimental site is not obvious in diversity and similarity of species,except mobile sandy dune.(4) All in all,as the increase of restoration time,there is a gradually increasing trend for number of species and seeds after artificial control.It can supply new individual and accomplish succession after vegetation was destroyed,so can reach intention of people for controlling sandy land to inseminate gridding vegetable sandy barriers.
