摘要

通过分析不同林地类型土壤特性及林地枯落物水文特性

对缙云山4种类型(针阔混交林、常绿阔叶林、楠竹林和灌木林)林地涵养水源功能进行了研究。结果表明

灌木林表土层有机质含量为楠竹林的3.75倍

针阔混交林有机质含量为楠竹林的2.22倍

常绿阔叶林有机质含量为楠竹林的1.53倍。枯落物蓄积量为16.21~32.42t/hm2

枯落物最大持水率次序为针阔混交林>灌木林>常绿阔叶林>楠竹林

最大持水量为灌木林>针阔混交林>常绿阔叶林>楠竹林。土壤非毛管持水量由大到小依次是灌木林(66.2 mm)>针阔混交林(57.52 mm)>常绿阔叶林(47.99 mm)>楠竹林(46.98 mm)。灌木林土壤饱和蓄水量最好

为266.48 mm;针阔混交林较好

为190.4 mm;常绿阔叶林次之

为186.8 mm;楠竹林最差

为1 74.8 mm。灌木林和针阔混交林较楠竹林有更好的涵养水源功能。在今后的森林经营中

应考虑营造灌木林和混交林。
