Objective] To provide the theoretical basis for ecological construction of returning farmland to forest in rocky desert area of north-west Guangxi.[ Method] Stand volume and water-holding characteristics of five types of forest litters of returning farmland to forest were re-searched in northwest Guangxi.[ Result] Total stand volume of five types of forest litters were in the order of Eucalyptus urophylla (11.59 t/hm2 ) >Zenia insignis(7.99 t/hm2 ) >Juglans regia (7.71 t/hm2 ) >Castanea mollissima(7.14 t/hm2 ) >Toona sinensis(3.70 t/hm2 ) .Water holding capacities of five types of forest litters were basically consistent,which were in the order of Toona sinensis >Castanea mollissima >Zenia insignis >Eucalyptus urophylla >Juglans regia.The water-holding capacity of the semi-decomposed litter was greater than that of the undecomposed litter.Water-holding capacity of the forest litter increased with the time prolonged.Semi-decomposed litter in-creased rapidly at 2 h; and undecomposed litter enhanced greatly when soaked for 4 h,and then entered into stable stage.Water absorption rate of the forest litter decreased as time prolonged.In the first 2 h,both the water absorption rate of semi-decomposed and undecomposed litter were the fastest.In 2-8 h after soaking,the rate gradually decreased.The rate declined slowly after 8 h.The effective interception rate of dif-ferent forest litters were in the order of Eucalyptus urophylla(36.89 t/hm2 ) >Castanea mollissima(26.65 t/hm2 ) >Zenia insignis(23.19 t/hm2) >Toona sinensis (16.64 t/hm2) >Juglans regia (15.36 t/hm2).[Conclusion] Eucalyptus urophylla has relatively great stand volume and effective holding capacity.During the construction of water conservation and soil and water conservation in future,we should increase the planting of Eucalyptus urophylla.%[目的]为桂西北石漠化地区退耕还林生态建设提供一定的理论依据。[方法]对桂西北5种退耕林分枯落物蓄积量与持水特性进行研究。[结果]5种林分林下枯落物总蓄积量大小依次为尾叶桉（11．59 t／hm2）、任豆（7．99 t／hm2）、核桃（7．71 t／hm2）、板栗（7．14 t／hm2）、香椿（3．70 t／hm2）；5种不同林分各分解层枯落物持水能力表现基本一致，从大到小均为香椿、板栗、任豆、尾叶桉、核桃，半分解层枯落物持水量大于未分解层；不同林分林下枯落物持水量随着时间增加而增加，半分解层在浸泡2h有较快上升，未分解层在浸泡4h明显上升，之后进入平稳阶段；不同林分枯落物吸水速率随着时间增加而减小，枯落物半分解层与未分解层吸水速率在浸泡2h内最快，2～8 h逐渐变小，8 h之后明显减缓；不同林分林下枯落物的有效拦蓄量大小为尾叶桉（36．89 t／hm2）、板栗（26．65 t／hm2）、任豆（23．19 t／hm2）、香椿（16．64 t／hm2）、核桃（15．36 t／hm2）。[结论]尾叶桉具有较大蓄积量和有效拦蓄量，今后在以涵养水源与水土保持为目标的森林经营中，可适当增加该树种的种植。
