农业气候区划工作是指导利用,开发各地气候资源的战略性措施。沿用的方法大都是先用某一气候象素(如降水量)做为一级区划的标准,把所讨论的范围分成为若干大区。再用另一要素(如积温或无霜期)做为进一步划分亚区的标准,从而进行定性的分区评价。其不足之处是:气象要素对所属气候区的具体贡献大小以及所有要素的综合贡献大小都不能从数量上精确地知道,且由于技术问题也不可能将要素选取的多一些。考虑到农业气候要素与当地作物产量形成间的模糊关系,以及产量是众多气象要素综合 Agricultural climate zoning work is to guide the use and development of climate resources around the strategic measures. Most of the methods used are first to use a certain climate pixels (such as precipitation) as a standard zoning, the discussion of the area is divided into a number of regions. Then use another factor (such as accumulated temperature or frost-free period) as a criterion for further sub-region, so as to conduct qualitative sub-region assessment. The shortcomings are: the specific contributions of meteorological elements to the climatic zones and the comprehensive contribution of all the elements can not be quantitatively known, and because of technical problems, it is impossible to select more elements. Taking into account the fuzzy relationship between the agro-climatic factors and the formation of the local crop yields, as well as the production of many meteorological elements
