| 摘 要： | 根据夏玉米对气象条件的要求,确定了河南省夏玉米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G IS技术对夏玉米不同生育期的温度、降水和日照等气候资源进行了网格推算。采用模糊数学方法,将全省划分为适宜种植区、次适宜种植区和不适宜种植区3个分区,并分别评述了各区域的特点,提出了建议。最后利用各县(市)夏玉米种植面积比例对本次区划结果进行了验证。

| Abstract: | According to the relationship between quality summer maize 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 such as temperature, precipitation and sunlight in grids were established by using the principles of Geographical Information System. Summer maize suitable planting area in Henan province was divided to three regions by using fuzzy mathematics method, which were suitable zone, sub-suitable zone and unsuitable zone. The characteristics in each zone were analyzed and suggestions were put forward as well. |
