Abstract：In this study,the glass greenhouse production is chosen as the study object.Then,based on the meteorological data from 69 surface observation stations from 1981 to 2020,according to the re-quirements of suitable light and temperature conditions for greenhouse crop growth,this paper determines three energy consumption stages,namely,no energy consumption period,heating energy consumption period and cooling energy consumption period,from the perspective of annual greenhouse production en-ergy consumption.In accordance with the main limiting meteorological factors that affect the glass green-house energy consumption and the research methods of agricultural climate resources,this paper also de-termines ten greenhouse climate zoning indexes,such as the period length,the total solar radiation and the effective accumulated temperature for each of the three stages,and the negative accumulated tempera-ture during the heating energy consumption period.Moreover,the principal component analysis method,systematic clustering method and the geographical information system are used in delineating the advanta-geous areas of glass greenhouse production in Jiangsu Province based on energy consumption.The results show that the most suitable areas lie in the northeast of Jiangsu Province and Fengxian County of Xuzhou City,the suitable areas are mainly between the Yangtze River and the Huaihe River and in the northeast-ern regions of the Huaihe River,and the sub-suitable areas are mainly located in southern Jiangsu.
