| 摘 要： | 选取周口10个气象站点1961—2017年的逐日气象资料,应用气候线性倾向率法、相关分析法、ArcGIS空间插值等,分析周口气候生产潜力时空变化特征。结果表明,1961—2017年周口夏玉米光合生产潜力、光温生产潜力和气候生产潜力年际变化均呈显著下降趋势,且年际波动较大;光合生产潜力空间分布呈现一定的带状分布,光温生产潜力空间分布特征不明显,气候生产潜力呈辐散型分布。

| Abstract: | Based on the daily meteorological data of 10 meteorological stations in Zhoukou from 1961 to 2017,the temporal and spatial variation characteristics of climate production potential in Zhoukou were analyzed by using the methods of climate linear tendency rate,correlation analysis and ArcGIS spatial interpolation.The results showed that the annual variation of photosynthetic production potential,light and temperature production potential and climate production potential of summer maize in Zhoukou from 1961 to 2017 showed a significant downward trend,and the annual fluctuation was large.The spatial distribution of photosynthetic production potential showed a certain zonal distribution,the spatial distribution of light and temperature production potential was not obvious,and the distribution of climate production potential was divergent. |
