The two tree water consumption characteristics, Populus simonii and Robinia pseudoacacie, and the interactions mechanism with environment factors were both studied at the level of leaf and singletree in terms of the modern technology of heat pulse sap flow and thermal dissipation sap flow probe. The two main purposes of study are to provide the science evidence in estimating the ecologic water consumption rules and to arrange better densities of the two tree species stand.
