摘    要:对茂兰喀斯特森林两种主要演替群落——喀斯特原生乔木林和次生林枯落物的储量和水文特性进行了调查研究,结果表明:两种演替群落枯落物的平均总储量为4.77 t/hm2,喀斯特原生乔木林的总储量要高于次生林;两种演替群落之间,枯落物的最大持水率和最大持水量均为喀斯特原生乔木林高于次生林;枯落物不同层次之间,两种演替群落枯落物未分解层的最大持水率和最大持水量均高于半分解层;枯落物的持水量和吸水速率与浸泡时间分别存在明显的函数关系:V=a ln(t)+b和S=ktn;在自然状态下,茂兰喀斯特森林两种演替群落枯落物的平均有效拦蓄量为8.31 t/hm2,喀斯特原生乔木林的有效拦蓄量要高于次生林。

Abstract:An investigation and study on the amount of litter and hydrological characteristics of Karst primary forest and secondary forest were conducted in the Maolan Nature Reserve,and the results were as follows: the average amount of litter was 4.77 t/hm2,in two different succession communities,and the amount of karst primary forest was higher than that of secondary forest.The maximum rate of holding water and maximum retention of primary forest were higher than that of secondary forest.The maximum rate of holding water and maximum retention of non-decomposed layers were higher than semi-decomposed layers’in different layers of the two different succession communities.Water holding capacity and water absorption rate of litter had obvious functional relationships:V = a ln(t)+b and S=ktn.The average effective retaining content was 8.31 t/hm2 of the two different succession communities in Karst areas in natural state,and the effective retaining of litter of primary forest was higher than that of secondary forest.
Keywords:forest litter  hydrological characteristics  Karst areas
