英文摘要	Pinus svlvestris var mongolica is a main tree species of the farmland shelter-belt and environmental protection system in the arid region of Northeast China. However, water resource in Shenyang city, Liaoning Province is much short-handed, soil moisture cannot satisfy the water requirements of P. mongolica growth under local natural conditions, more and more trees are being planted which needed to be irrigated, thus studying the transpiration characteristics of such tree species and its relationship with the meteorological factors and growth parameters is very important to the survival of trees in this region. On this background we took a research on the transpiration of indigenous P. mongolica tree species, while simultaneously monitoring the atmospheric and soil moisture contents. In this study, the sap flow rate (J(s)) of selected three 5a of P. mongolica tree samples were measured during 11th May to 15th October in 2019 by using the stem heat balance technique. Finally, we got results as follows: In the whole growing season, P. mongolica consumed water of 953.5 L (average value). Diurnal variation of J(s) fluctuation was transitionally changing in the growing season, adjusting to its way of water consumption. J(s) of P. mongolica tree species varied greatly under different weather, J(s) in rainy days were rather slow both in day and night, which reflect that the dynamic of water absorption diverse in the three trees. The vertical distribution of soil moisture content was observed throughout the whole growing season. In the 0.3-0.4 m soil layer contributed to most of the plant transpiration as the highest coefficient of determination at this layer. The variation in J(s) of P. mongolica could be described by a multiple linear regression against the meteorological variables. The Kendall's tau analysis indicated air temperature (T-a), solar radiation (R-n), and vapor pressure deficit (VPD) had great influence on sap flow of P. mongolica. To sum up, in the studied district afforestation was limited to T-a, R-n, VPD and top soil moisture factors.
