The "spring period" is a multifaceted term that refers to a season of ecological transition, a specific concept in physics, and a historical geopolitical era. 1. The Ecological and Meteorological Season
: Spring also marks the period of snowmelt runoff . In many high-altitude regions, snowmelt contributions to rivers peak between April and June, serving as a vital water source but also posing risks for spring flooding [12, 22]. 3. The "Spring Period" in History and Society spring period
For farmers, the spring period is the most high-stakes time of the year. It is primarily the for major crops, where success depends on a delicate balance of moisture and temperature [23]. The "spring period" is a multifaceted term that
Spring is officially defined by the vernal equinox, but its biological reality—known as —often begins much earlier. It is primarily the for major crops, where
This report confirms that the Spring Period is a critical ecological and cultural bridge between winter’s dormancy and summer’s peak productivity.
: In cold and arid regions, the "prespring period" is divided into stages based on the freezing and thawing of soil. Managing moisture reserves during this time is critical; for instance, winter management practices for pastures directly influence the feed supply available for livestock in the early spring [7].
: Research shows that the onset of spring is advancing globally due to climate change [3]. For example, studies on bird migration have noted that the onset of spring is moving forward at an average rate of 0.18 days per year , outpacing the rate at which some migratory species can adjust their arrival times [3, 26].
