【摘要】 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技术对棉花不同生育期的温度、降水和日照等气候资源进行了网格推算。根据棉花生产的气候适宜度函数和不同生育阶段的参数,分别计算了棉花不同生育期内光、温、水的气候适宜度,采用相对权重法得到综合适宜度。最后确定了基于气候适宜度的河南省棉花的农业气候区划指标和相应等级,并对各区域的特点及建议进行了分别评述。最后利用各县(市)棉花种植面积比例对本次区划结果进行了验证。更多还原

【Abstract】 Based on the geographic information and climate data of 114 meteorological stations in Henan Province from 1971 to 2000, the climatic elements in grids such as air temperature, precipitation and sunshine hours were established by using the principles of Geographical Information System. According to the climatic suitability models and the parameters in different stages of cotton growth, the climate suitability values of precipitation, air temperature and sunshine hours were calculated. The comprehensive impact of the three factors was evaluated by the relative weight method. The agricultural climatic regionalization indexes and different grades were studied and defined. The characteristics in each region were analyzed and suggestions were put forward as well. At last, the results were verified by the ratio between cotton planting area and cultivated area.更多还原
