Abstract: Using a newly-discovered combination of PCA(principal component analysis) and TOPSIS(technique for order preference by similarity to ideal solution),a study was carried out to evaluate and zone the meteorological hydrothermal resources for winter wheat in Hebei Province.Results show that Hebei Province can be divided into four zones in terms of climate suitability of winter wheat,i.e.South Hebei,the most suitable area for growth of winter wheat,where the heat and water resources match well;Central Hebei and Circum-Bohai area,where the relative imbalance of heat and water resources hinders somewhat growth of winter wheat;Northeast Hebei,where the water resource is tolerable,but lacks heat resource to match it;and North and Northeast Hebei,where the climate resources are the most unsuitable for growing winter wheat.
