中文摘要：
为了进一步优化江苏省冬小麦种植结构,利用江苏省1961—2010年气候资料和冬小麦产量资料,通过快速聚类分析法进行气候预分区,然后采用灰色关联分析法,建立分区冬小麦综合气候评价模型。以综合气候评价值为指标,对冬小麦种植区进行气候区划。结果表明：江苏省冬小麦种植区可分为弱筋小麦种植区、中弱筋小麦种植过渡区、中强筋小麦种植过渡区、强筋小麦种植区4个区。基于GIS,综合考虑了气象因素和小麦生态因素的气候区划结果将更加精细、准确、指导性更强。
英文摘要：
To optimize the plantation structure of winter wheat in Jiangsu Province,using the climatic data and yield data of wheat during 1961-2010.Firstly,preliminary climatic regions were made based on K-means Cluster Analysis in this paper.Then,a comprehensive climate evaluation model of winter wheat was established with the grey relational analysis.At last,the comprehensive evaluation value was used for the climatic division.The results showed that,quality wheat suitable planning area in Jiangsu Province was divided into four regions：the weak gluten wheat planning region,medium weak gluten wheat transition region,medium strong gluten wheat transition region and strong gluten wheat planning area.By using the principles of geographical information system,the wheat climatic regionalization with meteorological factors and ecological factors was regarded to be more precise,accurate and more instructive.
