This study on the size,composition and biodiversity of soil seed bank in Jinan,Yutai and Shouguang showed that the density of soil seed bank was 1 317.8±728.5 grains/m2 in Jinan,1 043.4±289.4 grains/m2 in Yutai and 483.4±129.5 grains/m2 in Shouguang respectively.The seed banks were mainly composed of dwarfish and short-life annuals including Gramineae,Compositae,Cruciferae and Amaranthaceae.42 species were found,among which,31 were annuals,9 were perennials,2 were shrubs,accounted for 73.8%,21.4% and 4.8% respectively.The index of similarity were 0.174 between Jinan and Yutai,0.010 between Jinan and Shouguang and 0.150 between Yutai and Shouguang.The Margalef index,Simpson's diversity index,Shannon-Weiner index and index of Eveness were 2.695,0.553,1.22,0.42 in Jinan respectively,while those were 4.115,0.711,1.96,0.59 in Yutai,and 1.966,0.796,1.80,0.72 in Shouguang respectively.
