| 摘 要： | 本文于1981－1984年植物生长季节对四川卧龙自然保护区森林土壤水分状况，进行了定位研究，试验林地设置在1200－4300m海拔高度的不同生物气候带的森林类型下。选择的五处试验林地是：①常绿阔叶林下的山地黄壤；②次生落叶阔叶林下的山地棕壤；③针阔混交林下的山地暗棕壤；④暗针叶林下的山地棕色暗针叶林土；⑤高山草甸植被下的高山草甸土。试验结果阐明了试验林地土壤的蓄水性能，枯枝落叶层最大蓄36-313t/ha，森林土壤的渗透系数在1．54－5．33mm/min，试验林地生长季节森林土壤水分贮量，都在最佳含水量下限以下，试验林地森林土壤水分供给（生态湿度）顺序为：山地棕色暗针叶林土（重湿）＞高山草甸土（重温）＞山地棕壤（湿）＞山地黄壤（较湿）＞山地暗棕壤（较湿一潮）。

| Abstract: | Permanent sample plots were located under forests in the 30°45' ~31°25'N and 102°52'~103°24' E, between 1200~4300 m above sea level, in the Wolong Natural Reserve. There are five mountain forest soil types for the sample plots:(1) mountain yellow soils under the evergreen forest, (2) mountain brown forest soils under the deciduous and broadleaf forest, (3) mountain dark brown forest soils under the coniferous deciduous and broad-leaf mixed forest, (4) mountain brown dark coniferous forest soils under the pure fir forest, (5) alpine meadow soils of the alpine meadow zone.Observation began in 1981 and ended in 1984. It is found that the forest soil moisture storage capacities in the experimental forest field are: maximum water-holding capacities of forest floor 36~313 t/ha, water-storage capacity of forest soil 611~2334 t/ha, forest soil permeability coefficient 1.54-5.33 mm/min, the degree of forest soil moisture supply: mountain brown dark coniferous forest soils (heavy moist)>alpine meadow soils (heavy moist)> mountain brown forest soils (moist)>mountain yellow soils (light moist)> mountain dark brown forest soils (low-light moist). |
