- Abstract:
-
To clarify the sap flow dynamic characteristics of main tree species on the Loess Plateau, we collected and arranged the relevant 19 published literatures with 11 tree 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 11 tree 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 11 tree 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.
