摘要: 为破解低海拔平原地区人工造雪的气象条件制约难题，提升造雪效率、降低能耗成本，本文以温度、湿度、风速为核心研究要素，结合浙江省湖州市低海拔平原人工造雪实践案例，系统剖析了低海拔平原人工造雪的核心气象逻辑、关键气象要素阈值要求及各要素对造雪质量的影响机制，并从监测网络构建、窗口期捕捉、技术手段适配三方面提出针对性的气象适配优化策略。研究表明，−2℃~−5℃的温度、≤60%的相对湿度、≤3 m/s的风速为低海拔平原高效造雪的最优气象阈值，三者的协同匹配是造雪成功的关键；通过构建分钟级精准气象监测网络、精准捕捉低温低湿微风的造雪窗口期以及适配专用造雪设备与人工干预技术，可有效突破低海拔平原低温不足、湿度偏高和风速不稳定的天然气象短板。本文研究成果为低海拔平原地区滑雪场运营、节庆雪景营造等场景的人工造雪作业提供了科学的实操参考，对推动冰雪运动在低海拔平原地区的普及具有重要实践意义。

Abstract: To address the constraints of meteorological conditions on artificial snowmaking in low-altitude plain areas, improve snowmaking efficiency and reduce energy consumption costs, this paper takes temperature, humidity and wind speed as the core research factors, and combines the practical cases of artificial snowmaking in the low-altitude plain of Huzhou City, Zhejiang Province. It systematically analyzes the core meteorological logic of artificial snowmaking in low-altitude plain areas, the threshold requirements of key meteorological factors and the influence mechanism of each factor on snowmaking quality, compares the differences in snowmaking meteorological conditions between the northern and southern low-altitude plains, and puts forward targeted meteorological adaptation optimization strategies from three aspects: construction of monitoring network, capture of snowmaking windows and adaptation of technical means. The results show that the optimal meteorological thresholds for efficient artificial snowmaking in low-altitude plain areas are a temperature of −2˚C to −5˚C, a relative humidity of ≤60%, and a wind speed of ≤3 m/s, and the coordinated matching of the three is the key to successful snowmaking. By constructing a minute-level accurate meteorological monitoring network, accurately capturing the snowmaking window with low temperature, low humidity and gentle wind, and adapting special snowmaking equipment and artificial intervention technologies, the inherent meteorological shortcomings of low-altitude plains such as insufficient low temperature, high humidity and unstable wind speed can be effectively overcome. The research results of this paper provide a scientific and practical reference for artificial snowmaking operations in scenarios such as ski resort operation and festival snow scene construction in low-altitude plain areas, and have important practical significance for promoting the popularization of ice and snow sports in these areas.
