Soil Seed Bank.

Zhang Zhiquan ( Department of Biology, Life Science School, Zhongshan University, Guangzhou, 510275)  
Soil seed bank has generally been defined as the amount of viable seeds present in the soil of defined area. Soil seed banks have been studied in various ways in various habitats, including arable soil, pastures, natural forests, forest plantations, lake shores, freshwater tidal marshes, salt marshes, prairie glacial marshes, deserts. On the basis of studies on relationships between latitude and the number of buried seeds in the soil, is does not appear to be a latitudinal trend in density of the buried seeds. It is concluded that there are four types of seed banks (TypesⅠ-Ⅳ) and three kinds of seed banks(Types A,B,C) Which are similar basically according to some research data. In frequently disturbed habitats the species composition of the seed banks and vegetation was usually similar. As the vegetation matures, the disparity between these two increased. A knowledge of the seed bank is of great value in the agriculture, forestry, conservation management and revegetation of mining wastelands.
