| Abstract: | In the Malan forest region of the Mt.Ziwuling on the Loess Plateau,three kinds of communities,i.e.the Pinus tabulaeformis forests,Quercus liaotungensis forests and shrub grasslands,were selected as the experimental plots.The seeds of Q.liaotungensis were sowed to build the seedling cohorts in three habitats.According to the growth data gathered continuously in three years,the dynamic life tables,curves of cumulative survival rate,cumulative mortality rate and hazard rate are drawn in this paper.The results ... |
