Abstract: Based on the mathematic formularization of PVcurve,it's shown that PV curve is linear whenpressure p=0.and nonlinear when p>0.At the same time,the new analysis by computer(Schulter,1988)was introduced and applied to Populus simonii data processing.The results show that at the saturated state leaf osmotic potential is 1.0512MPa,elastic modulus 1.7MPa;and at the turgor loss point,the relative water content(RWC),osmotic potential and elastic modulus are 83.5%, 1.3478MPa and 0.17MPa ,respectively,In the analysis modification,the statistic probability is 0.01 and R²reaches to 0.991. In addition,six kinds of figures of PV curves explain in detail the water relation of this woody plant.

Key words: phosphorous-rich area around Dianchi Lake, phosphate-solubilizing bacteria, chemotaxis, phylogenetic diversity.
