摘要
基于历史资料初步统计分析了1950—2000年间内蒙古地区低温冷害发生规律,利用ArcGIS空间分析技术研究了低温冷害发生频次和影响程度的空间变异,结果表明内蒙古低温冷害的发生在时间上具有不确定性、链式连年频发的特点,在空间上具有广泛性与区域性,玉米主产区受低温冷害影响严重。研究结果为提高光温资源利用率,并进一步开展低温冷害风险评估与区划及其气候背景研究奠定了基础。
Based on historical records on the frequencies and impacts of chilling injury during 1950 to 2000,statistical and spatial analysis using ArcGIS demonstrated its temporal and spatial changes in Inner Mongolia. Low-temperature injury showed temporal uncertainty and successiveness,and spatial prevalence and regional characters. Maize production distributes over chilling affected regions in Inner Mongolia. The results would benefit studies on the use efficiency improvement of light-temperature resource,risk assessment and zonalization,and climatological background of chilling injury in Inner Mongolia.
