| 摘要: |
| 根据1980~1990年的定位观测.广西龙胜县里骆林场23~33年生杉木人工林生态系统的自然贮水量结构为:乔木层17.2mm.灌木层0.1mm.草本层0.9mm.枯枝落叶层0.2mm.土壤层354.7mm;依次占系统总贮水量的4.61%、0.03%、0.24%、0.05%、95.07%。系统对大气降水的年分配为:林冠截留198.5mm,灌草截留27.2mm,枯枝落叶截留78.0mm,地表径流14.7mm,地下渗透65.9mm,土壤持水354.7mm,蒸散量870.1mm;依次占年降水量的12.91%、1.77%、5.07%、0.96%、4.29%、23.06%和56.58%。 |

| Abstract: |
| Based on the fixed-position observations from 1980 to 1990 on Lilo forest farm of Longsheng county, Guangxi, the natural moisture constitution in 23 to 33 years old Cunninghamia lanceolata artificial forest ecosystem is 17.2 mm at tree synusia, 0.1 mm at shrub synusia, 0.9 mm at herb synusia, 0.2 mm at litter layer, 354.7 mm at soil layer, and taking up 4.61%,0.03%, 0.24%, 0.05% and 95.07% of the total moisture respectively. The annual distribution of the precipitation in the ecosystem is Crown-interception 198.5 mm, shrub-and herb-interception 27.2 mm, litter-interception 78.0 mm, surface runoff 14.7 mm, underground seepage 65.9 mm, soil water retained 354.7 mm, evapotranspiration 870.1 mm, and taking up 12.91%, 1.77%, 5.07%, 0.96%, 4.29%, 23.06% and 56.58% of the annual precitation respectively. |
