河南省优质小麦精细化农业气候区划研究

Study on Precise Comprehensive Agricultural Climate Regional Planning of Quality Wheat in Henan Province

根据优质专用小麦生产对气象条件的要求,确定了河南省优质专用小麦的气候区划指标和相应等级。利用河南114个气象站点1971—2000年气候资料和台站地理信息,采用GIS技术对各气候要素进行了网格推算。采用专家打分法,将全省划分为强筋小麦适宜种植区、强筋中筋过渡区、中筋小麦适宜种植区、中筋弱筋小麦过渡区和弱筋小麦适宜种植区5个分区,并对各区域的特点及建议进行了分别评述。

According to the relationship between quality wheat and meteorological conditions, the agricultural climatic regionalization indexes and different grades were studied and defined. Based on the geographic information and climate data of 114 meteorological stations in Henan Province from 1971 to 2000, the climatic elements in grids were established by using the principles of Geographical Information System. Quality wheat suitable planning area in Henan Province was divided to five regions by using Expert Marking Method, which were strong gluten wheat suitable region, strong gluten wheat and medium gluten wheat transition region, medium gluten wheat suitable region, medium gluten wheat and weak gluten wheat transition region, weak gluten wheat suitable region. The characteristics in each region were analyzed and suggestions were put forward as well.
