| 摘 要： | 农田蒸散是形成土壤干旱的主要因素。本文采用陶祖文的彭曼修正公式对冀东地区的唐山、秦皇岛、乐亭、遵化等地3～11月的可能蒸散与可能实际蒸散进行了计算,并与本省南部的曲周做了可能蒸散量的对比分析。在统计分析的基础上,按《干旱分析方法的探讨》一文给出的华北地区干旱指标,用唐山农业气象站1980～1989年观测旱作地段的土壤湿度资料,对当地干旱的发生与干旱的指标进行了分析和验证。

| Abstract: | Field evaporation is the main factor in relation to drought. Using Porman Corrected Formula. Tle authors made a calculation to the possible and actual evaporation in field of East Hebei (Tangshan, Qinhuangdao)from March to November, and compared the result with that in Quzhou, South Hebei. By statistic analysis to the information of soil humidity detected by Tangshan wheat Bureau from 1980 to 1989, according to the standard presented in the artical"A Research On The Method Analysing Drought",the drought frequency and its grade in arid area of East Hebei was analysed and examed. |
