Abstract

To provide a basis for the regulation of hydrological ecological function and the species allocation of vegetation in Caohai Watershed,6 forest stands in Weining Caohai watershed(Pinusyunnanensis forest, Pinusyunnanensis- Populusyunnanensis forest, Populusyunnanensis forest,Camellia sinensis forest, Pinusarmandi forest and Cunninghamialanceolata forest)were chosen as research subjects,combined with field measurement and indoor immersion method,the differences in the thickness of litters,accumulations and water conservation processes were analyzed and compared,and the functions of water conservation were comprehensively ranked by coordinate analysis method.The results showed that:the total thickness of the litter layer of the six forest stands varied from 1.34to 3.26cm,the amount of accumulation was between 0.62 and 3.53 t/hm 2,and the maximum water-holding capacity was between0.76 and 5.57 t/hm 2,the maximum water-holding ratewas between 119.05 and 207.69%.The thickness accumulation and the maximum water holding capacity of the undecomposed layer were significantly higher than the semi-decomposed layer;the water-holding capacity of the undecomposed layer and the semi-decomposed layer of litter had a significant logarithmic relationship with the water immersion time:Q=alnt+b, R 2 >0.82;the water absorption rate of the litter had a power function relationship with the water immersion time:v=kt n, R 2 >0.98.The results of comprehensive analysis showed that the water conservation functions of the litter layers in the six forest stands from large to small: Pinusyunnanensis forest > Populusyunnanensis forest >Coniferous and broad-leaved mixed forest > Cunninghamialanceolata forest > Pinusarmandi forest > Camellia sinensis forest.The amount of accumulation of Pinusyunnanensis forest was the largest,the water holding capacity of Populusyunnanensis forest was the largest,and the water holding rate was the largest of Coniferous and broad-leaved mixed forest.From the perspective of water conservation function,it is recommended that the preferred tree species for vegetation restoration are Pinusyunnanensis and Populusyunnanensis in Caohai watershed.

Key words： Caohai watershed; litter; amount of accumulation; water conservation; forest land infiltration
