Soil seed banks in the Pinus bungeana forestland of the Huanglong Mountains on the Loess Plateau

    Corresponding author: LI Deng-wu

Abstract: This study aims to understand the composition structure and function characteristics of the soil seed banks in the Pinus bungeana forestland of the Huanglong Mountain area. A comparative study in species composition,vertical distribution,diversity,and other community ecological factors of soil seed banks in Pinus bungeana forests,which was undertaken by adopting the germination and grain combining methods. Treatments included three layers:0-5,5-10,and 10-15 cm layers and analysis included three indexes:the Margalef abundance,Shannon-Wiener diversity,and Pielou evenness degree. Regeneration and succession for four structural types namely,trees,shrubs,herbs,and lianas were also compared(12 plots,3 replications). The results indicated that the germination period was identical to the seed period in species structure. The soil seed bank contained 44 species belonging to 34 genera and 26 families in 2009. For individual seed number and species number,a significant difference(P<0.01)was found among soil layers with:0-5 cm >5-10 cm>10-15 cm. Index averages were Margalef abundance:3.87,Shannon-Wiener diversity index:3.63,and Pielou evenness degree index:1.15. For regeneration and succession,P. bungeana had a stronger regeneration capability with seeds at 39.2% of all tree species. Also,the herbaceous plants were 19.00% more than the woody plants in seeds and 36.36% in species number. Our results show there are significant differences in the vertical distribution of soil seed banks,and the composition of species remained relatively stable in the Huanglong Mountain area.[Ch,3 fig. 1 tab. 21 ref.]
