It seeds area and total yield are big in our country.This study combined Hubei province item of the project of country important food foisori science and technology. It considered the difference of climate character、 cultivate system and plant habit in the southeast of Hubei、 in the middle of Hubei、 in the northwest of Hubei and in the Jianghan plain four rice plant areas. It had formed " double season rice three ripe high yield in the southeast of Hubei mode "、" sparse、 manipulative、 weight middle season rice high yield in the middle of Hubei mode"、" zero till light-duty high yield plant in the Jinghan plain mode" and " cover with ground film wet in all process in the northwest of Hubei plant mode" four adaptive plant modes base on present plant modes.

And the average WDI for every month was calculated from 60 decades WDI and the drought frequency for every month was obtained with a drought criterion. Results showed that: in spring, North-western China, Northern China and Southern China have a higher drought frequency; in May to August, the region that has a higher drought frequency focus on North-western China and Northern China; from September to December, North-western China, Northern China, center China and Sichuan basin has a higher drought frequency (6) The relationship between average WDI for all the 720 decades in 20 years and average precipitation was analysed and was used to regionalize drought in China.

5分析我国近20年干旱发生的时空分布特征：利用1982-2001年NOAAAVHRR8km数据集，计算了20年来我国各旬干旱空间分布，并根据一定的干旱发生判断标准，统计我国不同地区在各月相发生干旱的频率和各月份平均WDI，初步分析我国干旱发生的时空格局，结果表明：在春季，西北地区、华北平原和华南大部分地区的干旱发生频率都比较高；在5-8月份，高频率干旱发生地区就主要集中在西北和华北平原地区；9-12月份干旱发生高频率地区在主要在西北、华北、华中和四川盆地等地。
