Abstract
[Objective] The research aimed to analyze the variation characteristics of sunshine hours in Puyang City in recent 51 yens. [ Method] Based on the monthly sunshine hours data in five meteorological stations of Puyang City during I960 -2010, the annual, seasonal and monthly variation trends of sunshine hows, time node of abrupt variation were analyzed by using the climate trend coefficient, climate tendency rale, sliding average method, SNR and so on. The objective fact and rule of sunshine variation in Puyaug in recent 51 years were re vealed. [ Result] The annual sunshine hours presented the declining trend in Puyang City in recent 51 years, and the declining range was 14.30 h/a. The seasonal sunshine hours presented the declining trend over the years, and the declining range was during -0.66 and -1.89 h/a. The maximum declining range was - 1. 89 h/a in summer. The monthly sunshine hours presented the declining Irend over the years, and the declining range was during -21.51 and -2.13 h/a. The maximum declining range was -21.51 h/a in July. The annual sunshine hours had one abrupt variation in 1983. The sunshine hours was more in the 1960s and 1970s. In the late 1980s, it was relatively less. [ Conclu sion ] The research provided the guidance value for the adjustment of plantation structure and the transformation of agricultural developed man ner in Puyang City.关键词
