摘要
对突脉青冈林分结构各层次持水能力及其林地土壤的持水能力和渗透性能的分析，结果表明：突脉青冈纯林中，密度为３０００株ｈｍ－２的林分林冠层持水量最大为９．４０４ｔｈｍ－２；若以林分的持水能力即地上部分与土壤的持水能力总量为指标，以４０５０株ｈｍ－２的林分为最好，总持水量最大，为１４９．５７２ｔｈｍ－２．
Based on analyzing the water storage capacity of forest structure stories and the water holding capacity and penetrating capacity of each woodland soil systematically,the results show that among pure Cyclobalanopsis elevaticostata stands,crown water holding capacity of stand whose density is 3000 culm\5hm -2 ,has the largest water storage capacity 9 404t\5hm -2 ,if total water storage capacity both aboveground and soil is regarded as the evaluating index,that of stand with 3000 culm\5hm -2 density is the largest one 149 572t\5hm -2 .Moreover the profits of stand water conservation in soil is estimated.
