[Objective] The effects of different management measures on water conservation capacity of litter layer of natural secondary forest were studied

and the management measures that are most conducive to improving the water source conservation capacity of litter layer are determined in order to provide theoretical basis and reference for the healthy management of natural secondary forest in this area.[Methods] Field measurement and indoor immersion method were used to analyze the change of water storage index in the litter layer

and to analyze the effects of five different kinds of management measures. The plots without management measures were set as the control

the water conservation of the stand was adopted

and the water conservation indicators were evaluated.[Results] ① After the transformation measures

the accumulation of litter was higher than that of the unmodified stands

and the amount of litter accumulated after 4 years was increased by 27%~39% compared with that before the transformation. ② After the implementation of the management measures

the growth rate of the maximum water holding capacity of the 2 a litter layer was 4.61%~9.30%

and the growth rate of 2 a to 4 a after the transformation was 6.31%~7.66%. ③ After 2-year and 4-yearr transformation

the natural water holding capacity of litter was:introduction of shrubs > closure of hills for afforestation > squash selective cutting > strip clear cutting > tending and thinning > unreconstructed. The growth rate after the 2-year transformation was 0.61%~29.68%

while the growth rate after the 4-year transformation was 1.82%~31.91%. ④ After the transformation

the effective growth rate of the litter layer after 2 years was 3.67%~8.08%

and the growth rate after 2-4 years was 4.51%~5.95%.[Conclusion] The water storage index of the litter layer in the forest with the implementation of management measures was higher than that in the unreformed forest stand. The management measures of shrubs introduced had the most obvious influence on the water storage capacity of litter.
