3. Abstract : on the loess plateau, water is the main limiting factors for vegetation growth. root distribution characters have special ecological meaning as it reflected the utilizations of trees to the environments. even - aged stands of robinia pseudoacacia on slope lands facing south and north were selected as sampling plots for root distribution investigation. investigatiing results showed that indicated that on all sites, root biomass decreased with depth, and the distribution depth of fine root was deeper than that of coarser root. the results of variance analysis indicated that there were great differences in root biomass among different diameter classes, and coarser root was the main sources of variance, and the root biomass, especially fine root ( < 3mm ) biomass on northern exposition sites was bigger than that on southern exposition sites. analysis of the vertical root distribution parameters, root extinction coefficient, indicated that the value of on northern exposition was more than 0. 982, while the value of on southern exposition was less than 0. 982, which indicated that the vertical root distribution depth of robinia pseudoacacia on southern exposition was deeper than that on southern exposition. and the distribution depth of fine roots ( < 1mm ) was deeper than that of thicker roots ( < 3mm ), which was in favor of the uptake of water and nutrients from deeper layers, helped the trees to adapt the arid environment, and promoted the growth of the upper parts of the tree
   文摘:在中國西北黃土高原地區，水分是樹木生長發育的主要限制因子.根 系 分佈特徵由於反映了樹木對環境條件的利用程度而具有更加特殊的生態意義.本研究選擇陽坡和陰坡不同立地上年齡一致的刺槐林調查了根 系 分佈特徵.根 系 垂直分佈特徵的調查結果表明，在所有立地上，根 系 生物量隨著深度的增加而降低，其中細根的分佈深度大於粗根的分佈深度.方差分析結果表明:不同立地上不同徑級根 系 的分佈特徵也有明顯的差別，粗根是差異存在的主要原因，陰坡立地上的根 系 生物量，特別是細根生物量大於陽坡立地上的.對根 系 消 弱 系 數 的分析結果表明，陰坡立地上的根 系 消 弱 系 數 大於0 . 982 ，而陽坡立地上的根 系 消 弱 系 數 小於0 . 982 ，說明陰坡立地上刺槐根 系 的生物量在深層土壤中的分佈相對量更大一些.其中細根的根 系 消 弱 系 數 大於粗根的，這種根 系 分佈特徵有利於根 系 對深層土壤水分養分的吸收利用，進而促進樹木地上部分的生長發育.圖3表3參15
