  moss layer
The greatest increase of seedling recruitment was observed in the plots with the moss layer removed.
      
In a four-year removal experiment we investigated the effect of removing a dominant species (Nardus stricta), the litter layer and moss layer on species composition of established vegetation and on numbers and species composition of seedlings.
      
On the Karula Upland, South Estonia, the forest moss layer was analysed using a transect of 726 contiguous 0.2×0.2 m plots.
      
The majority of added particles were fixed in the upper part (90% in 1-3 cm) of the moss layer.

: The canopy density and the interception rate of Sichuan Miyaluo subalpine forest are in positive correlation,the interception rate reaches 24% when the canopy density is 0.7 and decreases to 9.5% when the canopy density is 0.3(measured during May and July)litter of arrow bamboo fir mixed stand has the maximum water retaining capacity(6.0 mm)and music fir mixed stand has the minimum(2.8mm),because the former has more associated broad leaf trees and shrubs.The maximum soil water holding capacity,maximum litter water holding capacity and maximum moss layer water holding capacity of the primitive fir forest of Minjiang is much greater than that of the other vegetation types such as secondary growth after cutting.The runoff of the well coverd valley is greater than that of wasteland or open forestland.As to different cutting methods,the runoff increment is:clear cutting> selection cutting>no cutting.Compared with other forest types of China,the relative forest evapotranspiration ratio(Evapotranspiration/preci pitation)of the upper reaches of the Yangtze River is relatively low(30~40%)because of the high altitude and the greater amount of precipitation.

长江上游森林林冠截留量与林分郁闭度呈正相关, 当亚高山冷杉林的林分郁闭度为0.7时(5~7月), 平均截留率为24%, 当郁闭度在0.3时(5~7月), 平均截留率降为9.5%;从枯落物持水量来看, 箭竹冷杉林最大(6.0mm), 藓类冷杉林最小(2.8mm), 主要因为前者有较多的落叶伴生树种和灌木。岷江冷杉原始林的土壤最大持水量、枯落物最大持水量、苔藓层最大持水量比皆伐后形成的其他森林类型要大2.3~17.2倍, 从而具有更好的水源涵养功能。植被对径流的影响初步结论是, 森林大流域的年径流量常常大于少林或无林流域的径流量;不同采伐强度径流量比较是皆伐迹地>择伐迹地>原始森林。与全国其他森林类型的蒸发散研究比较显示, 长江上游森林的相对蒸散率较低, 为30%~40%, 这主要是由于海拔较高, 降水量大所致。

Maximum interception capacity and interception ratio of litters and moss in subalpine Abies fabri forest of upper reach of Yangtze River are between 2.4~2.9mm and 20%~30% respectively. Interception capacity of different components of litters and moss rank as follows: litters layer>moss layer>humus layer. Initial water content, precipitation quantity and precipitation intensity are the major factors influencing water transport in litters and moss layer. Interception capacity and interception ratio decrease with the increasing of precipitation intensity and initial water content and rise with the increasing of precipitation. When precipitation quantity exceeds the threshold of interception capacity of litters and moss, the litters and moss layer will loss its interception function and only maintain its runoff deterrence role. At last, that how to solve the comparability problems in measuring the interception function of litters and moss is still a problem in forest hydrology research is proposed.

长江上游亚高山峨眉冷杉林地被物层平均降雨截留为 2 .4~ 2 .9mm,对林下降雨的平均截留率在 2 0 %~30 %之间。地被物层各组分对降雨的截留作用大小排序为枯枝落叶层 >苔藓层 >腐殖质层。初始含水量、降雨量和降雨强度是影响地被物层水分传输的主导因子。地被物层截留与雨强、初始含水量均呈负相关 ,与降雨量在一定范围内呈正相关 ,但当地被物吸水达到其截留极值点后 ,完全成为一层水流通道 ,只起阻延水流速度的作用。文中最后提出如何解决地被物截留作用的可比性问题将是森林水文的一个难点。
