近年来，许多城市在冬季降雪后不再大规模使用融雪剂，这一变化背后有多重原因。首先，传统氯化钠、氯化钙等融雪剂虽然能快速融化冰雪，但对环境和基础设施具有显著危害。它们会腐蚀道路、桥梁钢筋，缩短使用寿命；渗入土壤后影响植物生长，甚至污染地下水。其次，随着环保理念深入人心，各地政府更加注重生态友好型除雪方式。例如，采用机械除雪为主、人工清扫为辅的方式，或使用环保型融雪材料（如醋酸钙镁）替代传统盐类。此外，部分城市通过精细化天气预报提前部署除雪力量，减少对化学融雪剂的依赖。2024年多地明确限制或禁止在人行道、绿地周边使用融雪剂，正是这一趋势的体现。总体来看，‘少用或不用融雪剂’不仅体现了城市管理的科学化，也反映了可持续发展的新要求。
In recent years, many cities have stopped using large amounts of chemical de-icing agents after snowfall—a shift driven by multiple factors. Traditional de-icers like sodium chloride and calcium chloride melt ice quickly but cause significant environmental and infrastructural damage. They corrode steel reinforcements in roads and bridges, shortening their service life, and can leach into soil, harming vegetation and even contaminating groundwater. As environmental awareness grows, municipal governments are increasingly adopting eco-friendly snow removal methods. These include prioritizing mechanical plowing supplemented by manual clearing, or replacing salt-based agents with biodegradable alternatives like calcium magnesium acetate. Moreover, improved weather forecasting now allows cities to pre-deploy snow-clearing resources more efficiently, reducing reliance on chemical treatments. In 2024, numerous regions explicitly restricted or banned the use of de-icing agents near sidewalks and green spaces—a clear sign of this evolving approach. Overall, the move toward minimizing or eliminating chemical de-icers reflects both smarter urban management and a stronger commitment to sustainable development.
