| 摘 要： | 利用河南省30个农业气象基本站的土壤测墒资料,把冬小麦干旱划分为轻、中、重3个干旱等级,通过构建干旱指数函数,分别计算出不同干旱等级的干旱指数,绘制干旱指数分布图,结果表明:河南省冬小麦干旱以豫北林州,豫西大部,豫中许昌,豫南西平、驻马店等地发生较频繁且以轻旱为主。

| Abstract: | Using the soil humidity data of 30 agrometeorological base station in Henan province,the winter wheat drought is divided into 3 grades,such as light,moderate and heavy.The drought exponential function was constructed and the drought index was calculated and drawn.The results showed that drought locality were Linzhou,large parts in the west,Xuchang in the middle,Xiping and Zhumadian in the south.And the light drought is the mainly drought type in the areas. |
