模拟寒冷地区融雪过程中的养分输送仍然是一个重大的科学挑战。现有营养模型在寒冷地区应用的一个主要限制是融雪的代表性不足，包括水文和生物地球化学过程。这一短暂的时期可占加拿大大草原和加拿大北部年地表径流总量的80%以上，大气沉降、冬季雪的重新分布、雪晶中的离子排除、冻土以及融化过程中积雪覆盖面积的损耗等过程会影响雪和土壤养分的分布和释放，从而影响融雪径流养分浓度的时间和大小。
Modelling nutrient transport during snowmelt in cold regions remains a major scientific challenge. A key limitation of existing nutrient models for application in cold regions is the inadequate representation of snowmelt, including hydrological and biogeochemical processes. This brief period can account for more than 80% of the total annual surface runoff in the Canadian Prairies and Northern Canada and processes such as atmospheric deposition, overwinter redistribution of snow, ion exclusion from snow crystals, frozen soils, and snow‐covered area depletion during melt influence the distribution and release of snow and soil nutrients, thus affecting the timing and magnitude of snowmelt runoff nutrient concentrations.
