| 摘 要： | 分析了元阳梯田区域12个植物群落土壤层和枯落物层涵养水源的能力,结果表明:各阔叶林地土壤容重都小于1.00 g/cm3,针叶林群落改善土壤结构的能力弱于阔叶林。山地山龙眼群落土层的平均总孔隙度最大,为61.80%,饱和蓄水量和非毛管持水量最高,分别为1 235.9和226.4 t/hm2。木姜子、红果树阔叶混交林的土壤涵养水分能力强,表层土田间持水量为77.20%和75.72%。阔叶林枯落物的持水能力强,针叶林群落产生的枯落物量大,杉木林和云南松林的枯落物持水总量为991.54和1 570.40 g/m2。云南松群落和山地山龙眼群落综合持水能力较强,分别为2 521.6和2 163.8 t/hm2。草地群落持水能力最弱,仅为1 099.4 t/hm2。

| Abstract: | The paper analyzes the capacity of water conservation of soil and litters of 12 plant communities in terraced field region of Yuanyang.The outcomes show that the soil volume weight of each broad-leaved forest is smaller than 1.0 g/cm3 and the capability for improving soil structure of coniferous forest community is weaker than that of broad-leaved forest.Among the 12 plant communities,the average total porosity of Helicia clivicola community is maximum as 61.8%,and the saturated water storage capacity and t... |
