| 摘 要： | 通过对安徽省中南部主要森林类型林下枯落物蓄积量、持水量、吸水速率等的研究，结果表明：①针叶林中杉木（CK）枯落物的厚度最大，达到95mm，针阔混交林的蓄积量最大，为21．94t／hm2，马尾松枯落物的厚度较低，苦槠蓄积量最低。②马尾松×枫香的最大持水量为12．62t／hm2，其他林分的最大持水量均在10t／hm2以下，其中苦槠最低，为2．04t／hm2。③针阔混交林的有效拦蓄能力明显高于阔叶林和针叶林，有效拦蓄量最高的是马尾松×枫香，为17．69t／hm2．苦槠的有效拦蓄量最低，仅为2．47t／hmz。两种不同杉木林分有效拦蓄量均达到10t／hm2左右。可见针阔混交林的水文生态效益优于阔叶纯林和针叶纯林。

| Abstract: | In this paper the hydrological characteristics including the litter accumulations, water-holding capacities and water absorption rates of the main forest types in central and southern Anhui were studied. The results indicated that： ①In the coniferous forests, the thickness of the leaf litter of Cunninghamia lanceolata （check control） was the biggest, reaching 95 mm, and that of Pinus massoniana was smaller. The leaf litter accumulation in the mixed coniferous and broad-leaved forest was the biggest, being 21.94 t/hm2, and that in the forest of Castanopsis sclerophylla was the smallest. ②The maximum water-holding capacity in the mixed forest of Pinus massoniana and Liquidambarformosana Castanopsis sclerophyUa was 12.62 t/hm2, and those in other forests were below 10 t/hm2, with that in the forest of Castanopsis sclerophylla being the lowest, only 2.04 t/hm2. ③The effective rainwater conservation capacity of the mixed coniferous and broad-leaved forest was obviously higher than those of the broad-leaved and coniferous pure forests, and that of the mixed forest of Pinus massoniana and Liquidambarformosana was the highest, being 17.69 t/hm2, while that of Castanopsis sclerophylla was the lowest, being only 2.47 t/hm2. The rainwater conservalion capacities of the 2 different stands of Cunningharaia lanceolata both reached about 10 t/hm2. The results showed that the hydroecological benefits of the mixed coniferous and broad-leaved forest were higher than those of the broadleaved and coniferous pure forests. |
