| 摘 要： | 在喀斯特森林生态系统水分生态循环过程中,苔藓植物蓄水层的存在具有重要的生态意义。本文通过对云台上喀斯特苔藓植物生物量、鲜重、饱和含水重的测量分析,计算出总的苔藓群落样品平均自然储水量为0.104 t/ha,饱和蓄水量为0.52 t/ha。森林下各个种苔藓群落吸水率和蓄水量有明显差别,其变化范围是:自然吸水率Rn=1~4,饱和吸水率Rm=8~31;自然蓄水量4.5~1 532.2g/m2,饱和蓄水量33~11 508.9 g/m2。在各种生态类型中,石生群落蓄水量最大。

| Abstract: | The water-holding layer of bryophyte communities is very important for water circulation and succession in karst forest ecosystem.The amount of average natural water-holding capacity at Yintaowan in Yuntai Mountain were estimated at 0.143t/ha and saturation water-holding capacity at 0.93t/ha,based on a computation of the analytical results for fresh weight,saturation water-holding weight and biomass of all the bryophyte communities in this area.Natural water-holding rate of bryophytes comnuminties is 1~4,saturation water-holding rate 8~31;natural water-holding capacity of bryophyte communities is 4.5~1532.2g/m2.Among three ecological groups,the water-holding capacity of bryophytes communities on dolomite rock is dominant. |
