本文依据河北省太行山区25个气象站生长季内≥0。C的活动积温和降水量资料,采用相对干燥度指标,对太行山区旱涝对空分布作了探讨,揭示出该区旱涝灾害的时空分布规律具有一致性、区域性和波动性。最后,针对农业生产实际作了旱涝灾害的农业气候分析。 This article is based on 25 meteorological stations in Taihang Mountain area of ​​Hebei Province during the growing season ≥0. Using the relative dryness index, the distribution of drought and flood in the Taihang Mountains was discussed, and the spatial and temporal distribution of drought and flood disasters in this area was consistent, regional and fluctuant. Finally, agriculture and climatic analysis of the real drought and flood disaster.
