The region along the Great Wall is a typical dryland agricultural zone, serving as both potential area for staple grain production and key specialty crops like coarse grains cool-climate vegetables. Studying characteristics of drought during spring sowing period crucial developing diversified planting strategies ensuring food security. This study analyzes conditions from 1960 to 2023, revealing spatial temporal distribution in quantifying impact climate change on frequency intensity. By doing so, it fills gap existing research, which often lacks long-term, multi-dimensional analysis characteristics. Using daily meteorological data April 20 May between employs Meteorological Composite Drought Index (MCI) quantitatively identify examine evolution region. results show that, scale, mild moderate droughts 60.45% 25.19%, respectively, with no occurrences severe or extreme drought. On an annual intensity ratio affected stations increasing trend, decrease increase occurrences. Additionally, follows pattern “higher east than west” north south”. also finds that migration centers shows clear evolution, center shifting southwestward 1960s 2000s, then moving northeastward 2000s 2023. These findings provide critical support optimizing resistance offer new insights future research relationship change. It suggested practices water resource management policies should be adjusted according centers, particular focus mitigation measures period.
