| 摘 要： | 借助地理信息系统与数学模型,利用福建省气象观测数据,通过二次趋势面与反距离权重插值模型推算福建相关气温因子,进而对秋花生种植气温限制因子进行动态聚类。结果表明,福建省秋花生种植气温重度限制、中度限制、轻度限制和无限制面积分别占耕地总面积的42.22%、18.21%、14.56%和25.01%,限制程度表现出由闽东南向闽西、闽中、闽北及闽东地区逐渐加重的空间分布趋势。

| Abstract: | Based on meteorological data and GIS,the correlative air temperature factors were calculated in Fujian Province by combining quadratic tendency curve model with inverse distance weighted interpolation,the dynamic clustering analysis was used to classify the restrained factor of air temperature for autumn peanut(Arachis hypogaea) planting.Results showed that the planting area for autumn peanut restrained by the air temperature took 42.22%,18.21%,14.56%,25.01% to the total farmland area for most serious,more serious, slight and none respectively.The Southeast of Fujian Province was the most suitable region for the autumn peanut planting,while the suitability for the autumn peanut planting ranged from the Southeast to the West,Middle,North and East of Fujian Province. |
