Abstract:: Using the observation data of Photosynthetically Active Radiation(PAR) and adjacent weather stations of an international horticultural expo address (Chanba) from April to October in 2011, and the application of statistical methods, the basic characteristics and the origins of those PAR and η_Q (Photosynthetic active radiation coefficient) data was analyzed. The results showed that from April to October in 2011, Xi’an international horticultural EXPO address displayed 5 095.2 mol/m² PAR, with a monthly and daily average sum of 727.9 mol/m², 23.8 mol/(m²·d), respectively. PAR sum was higher in summer than in spring, and it is greater in spring than in autumn due to the intensive autumn precipitation; the daily changes of PAR were bigger at noon, and smaller in the morning and evening. PAR in spring and summer were evidently higher than autumn, PAR in sunny days were often 500～600 mol/m², and it was always 200～300 mol/m² in cloudy days; η_Q had obvious monthly and seasonal variation characteristics. The fitted curve showed twin-peak type: July and October for peak months, May and September for valley months. η_Q value was maximum in summer, it ranked the second in autumn, and it was minimum in the spring; Daily-change characteristics of η_Q indicated that cloudy days were clearly higher than sunny days, with an average difference of 0.47 mol/MJ. Finally, the most suitable climatology experience formula for η_Q calculation in Chanba Xi’an was put forward.
