Abstract: | Our study dear with the determination of sapwood sap flow of a single Populus euphratica tree by heat pulse technique and the calculation of water consumption of an entire forest stand, given the correlation between sap flow and sapwood area of P. euphratica. The relation between diameter at breast height (DBH) and sapwood area constitutes a powerful model; these variables are highly correlated. By means of an analysis of DBH in the sample plot, the distribution of the sapwood area of the forest land was obtained and the water consumption of this P. euphratica forest, in the lower reaches of the Heihe River, calculated as 214.9 mm by standard specific conductivity of the sample tree. |
