| Abstract: |
| Using standard climate statistics from 26 meteorological stations during 1971~2000 and 1:25 million ge-ographic information, the authors established a regression model between climatic regionalization factors of potato planting
area and geographic information, identified the indicators of comprehensive climatic regionalization factors in Xing' an League, and also divided the Xing’an League into appropriate, second appropriate and inappropriate areas for potato planting by GIS technology. The result shows that north-west of Xing’an League in Inner Mongolia is a high quality potato - producing base because of its cool climate , big day-night temperature difference and good wetting degree. Potato planting area should be gradually expanded in this region. The climate of south Xing’an League is disadvantageous for high quality and high-yield potato planting because of its too high temperature in July，little precipitation and small day-night temperature difference. Potato planting area should be gradually reduced in this region. The central south of Xing’an League is second appropriate for potato planting because of its mid heat resources and relatively higher precipitation. The divisional results have an important reference value to the rational use of climate situation , farming structural adjust-ment, and the improvement of the quality and yield of potato production. |
