Summary:In order to study the responds of stomatal traits of desert plant to climate change and the effects on plant carbon sequestration capacity, the typical plants Nitraria tangutorum was chosen as research materials. According to annual average precipitation of Dengkou and the plant growth regulation, two precipitation enhancement period(early growing season and late growing season) were designed, each precipitation enhancement period with two rain enhancement gradient(50% and 100%), the artificial simulation of precipitation experiment to natural N. tangutorum shrubs was conducted. The stomata size, density and conductance of N. tangutorum leaves in different rainfall simulation treatment were studied with a Motic digital imaging microscope. The results showed that the precipitation treatments increased the stomata size(length and width) and stomata conductance of leaves compared with the control, on the contrary, the stomata density decrease in precipitation treatments, and the density of lower epidermis of lea
