Abstract

Water holding characteristics, including, water holding capacity, water holding rate and absorption rate, together with the litter stock from five public welfare forests with different tree composition and identity were measured. The purpose was to understand water-conserving functions of the three plantations. The results showed that litters from five public welfare forests have different characteristics. The great litter production of litter in different ecological public welfare forest types was of Pinus yunnanensis forest, followed by the litter of Alnus nepalensis forest, Cunninghamia lanceolata forest, Eucalyptus globulus forest, and the least amount of litter stock was from Quercus variabilis forest. The total water holding capacity and water holding rate of litter increased logarithmically with increasing immersing time, according with logarithmic equation W=a*ln(t)+b. Water absorption rates of litter in all plantations decreased according to power correlation with increasing time immersed in water, it accord with power equation W=a*t-b (P < 0.001).
