Abstract

为了明晰黄土高原主要树种树干液流的动态特征,该文通过对已发表相关文献搜集与整理(19篇涉及11个
树种),采用meta分析手段归纳黄土高原主要树种树干液流动态、耗水规律及其影响因素。研究发现:(1)该区主要树
种树干液流存在明显的昼夜变化规律;(2)太阳辐射、水汽压亏缺、土壤含水率是影响树干液流的主要环境因素;
(3)树干液流测量手段、树木生长阶段以及测量时的天气条件会给树木蒸腾耗水估算带来不确定性;(4)11个树种的
蒸腾耗水量大小的顺序为:针叶树种(侧柏、油松)<乡土阔叶树种(白榆、辽东栎、旱柳、柠条、河北杨、小叶杨、山杏)<
外来阔叶树种(刺槐、苹果)。本研究为黄土高原地区造林树种的合理选择及树种耗水评价提供参考。

Other Abstract

To clarify the sap flow dynamic characteristics of main tree species on the Loess Plateau,we collected and
arranged the relevant 19published literatures with 11tree species and a meta analysis was used to summarize
the daily dynamics of stem sap flow,water consumption situation and their influence of environmental factors
of the 11tree species.The results suggested that:(1)stem sap flow of the main tree species exhibited diurnal
patterns in this area;(2)solar radiation,vapor pressure deficit and soil moisture were the principal factors affecting
stem sap flow;(3)estimate of tree water-consumption for transpiration always had uncertainty because of the difference
in the methods of measurement,trees growing stage and the weather condition of the measurement;(4)the
order of the transpiration in 11tree species was as following:native coniferous species(Platycladus orientalis,
Pinus tabuliformis)<native broadleaved species(Ulmus pumila,Quercus liaotungensis,Salix matsudana,
Caragana korshinskii,Populus hopeiensis,Populus simonii,Armeniaca sibirica)<exotic broadleaved
species(Robinia pseudoacacia,Malus pumila).This study will provide the reference for selection of afforestation
tree species and evaluation of tree water consumption on the Loess Plateau of China。
