Ecohydrological functions of litter in man-made Acacia Mangium and Pinus elliotii plantations
马占相思 (Acacia mangium)与湿地松 (Pinus elliotii)人工林枯落物层的水文生态功能

The ecohydrological functions of litter were studied,which include litter storage,annual litterfall and dynamics,water holding capacity,interception effect on rainfall,restraining effect on soil water evaporation,and retarding effect on runoff.The results are suggested as follows. litter storage in Acacia magium and Pinus elliotii plantations are 32 3t/hm 2 and 18 7t/hm 2.Annual litterfall are 11 14t/hm 2 and 7 30t/hm 2,The maximum water holding rates are 253 7% and 216 7%,and ...
