【摘要】 对1987年营造的水曲柳针叶混交林和水曲柳纯林的静态持水能力进行了研究,结果表明:枯落物最大持水量和有效持水量分别为16.07~21.65 t.hm-2和9.05~12.82 t.hm-2,林地土壤的单位面积有效持水量变化范围为257.6~506.6 t.hm-2,土壤饱和持水量的变化范围为2 871.2~3 035 t.hm-2。综合比较,水曲柳针叶混交林静态持水能力都要好于水曲柳纯林,在3种水曲柳针叶混交林中水曲柳红松混交林持水量最大;其次是水曲柳云杉混交林;水曲柳落叶松混交林最小。更多还原

【Abstract】 Moisture retention power of the mixed and pure forest of Fraxinus mandshurica was investigated.The results indicated that the maximum moisture capacity of the litter varied from 16.07 to 21.65 t·hm².And its effective moisture capacity varied from 9.05 to 12.82 t·hm^-2.The saturation moisture capacity of the soil varied from 2 871.2 to 3 035.0 t·hm^-2,and its effective moisture capacity varied from 257.6 to 506.6 t·hm^-2.Static moisture retention power of the mixed forest of Fraxinus mandchurica with conifer was better than pure forest of Fraxinus mandchurica. Among three mixed forest of Fraxinus mandshurica and conifer,water conservation capacity declined order was the mixed forest of Fraxinus mandshurica with Pinus koraiensis,the mixed forest of Fraxinus mandshurica with Picea asperata,the mixed forest of Fraxinus mandshurica with Larix.更多还原
