【摘要】 该文利用顺德国家气象站和自动站资料,运用气候学计算方法、5 d滑动平均法、分组法和直方图法分析了顺德地区的光照和热量资源。结果表明:顺德月太阳辐射呈现单峰型,以7月最大,2月最小。年平均太阳辐射总量为4 531.874 MJ/m2,属于太阳能资料较贫乏带。顺德月光合有效辐射(PAR)为119.68~263.38 MJ/m2,平均为184.286 MJ/m2,也呈现弱单峰型。≥15℃的初日提前不明显,终日延迟趋势显著。制作保证率日期表,以供农业气象分析查询使用。顺德积温地域分布存在"东高西低"形势。更多还原

【Abstract】 Based on the observed data from Shunde and regional automatic weather stations,the method of climatological calculation,five day running average method,grouping and histogram method were used to analyze the agrometeorological conditions of heat and Light in Shunde。The results show that: 1annual variation of solar radiation took the form of one- peak,with July maximum and February minimum. 2Yearly solar radiation 4 531. 874 MJ / m2 belong to the poor; 3PAR ranged from 119. 68 ~ 263. 38 MJ / m2 and the average is 184. 286 MJ / m2,annual variation of PAR took the form of one- peak too. 4the initial dates of ≥15 ℃ isn’t obviously earlier beginning,but later ending in the final dates. 5Make table of surance rate for the query of agrometeorological conditions. 6Distribution of accumulated temperature of ≥15 ℃ in Shunde " East High and west low" situation.更多还原
