Abstract:

Using standard climate statistics from 8 Meteorological stations in Xing'an League and 18 meteorological stations in neighboring provinces and regions during 1971-2000, the authors established a regression model between climate division factors of spring maize and geographic information ,identified the indicators of comprehensive climate division factors in Xing'an League, and also divided the Xing'an League to appropriate ,more appropriate and inappropriate areas for maize planting, at the same time ,the authors made some recommendations to avoid the hazards. Divisional results have an important reference value to the rational use of climate situation,to reduce the risk of maize production and farming structural adjustment.
