摘      要：The paper, by the flexible classification in fuzzy mathematics, uses precipitation, meantemperature, sunshine duration, dry index (namely evaporation to precipitation in the corre-sponding period) and cumulative temperature≥10°C between March to September asclassifying indices, and classifies the whole region of Ningxia. We have obtained resultswhich are basically in accordance with the previous divisions, but has some differences.
