摘  要:
通过对重庆市缙云山3种水源涵养林林下枯落物储量调查分析及持水特性试验,得到不同森林类型林下枯落物储量、最大持水量、最大持水率等水文特征参数。结果表明,枯落物储量为标准地2>标准地1>标准地3,枯落物最大持水量为标准地1>标准地2>标准地3,枯落物最大持水率为标准地3>标准地1>标准地2;针阔混交林林下枯落物持水量大于针叶混交林林下枯落物持水量,进一步说明了林分结构越复杂,其林下枯落物持水量就越大。

摘  要:
Water-holding characteristic experiment and the investigation of the source of dried life thing reserves were con-ducted under 3 kinds of forest in Jinyun mountain area in Chongqing City.The source of dried life thing reserves and some hydrology characteristic parameter as maximum water-holding amount,the maximum water-holding rates were measured.The result indicated that source of dried life thing reserves in standard field No.2 was > that in standard field No.1> that in standard field No.3.In the maximum water-holding amount of dried life thing,the order was standard field No.1 > standard field No.2> standard field No.3.The order of maximum water-holding rates was standard field No.3 > standard field No.1> standard field No.2.The results indicated water-holding ability of dried life thing under broad leaf and needle leaf mingled forest was greater than needle leaf mingled forest.
