In northern regions, pollution of falling snow and piling one and its influence on the natural environment are becoming serious problems.Snow as well as rain is polluted while falling down through the air and after laying on the ground one is contaminated with harmful materials originated by human activities. Such polluted snow melts in a very short period in spring and influences the environment, especially water quality. Actually, eutrophication and pollution of organic substances and heavy metals are observed. This study, recognizing the facts above, aims at clearing the actual conditions of polluted snow and pollution mechanism and proposing some pollution control methods in order to control the water environment. It was found out that;1. Snow laid on the ground is extremely polluted by a great amount of road dusts and wastes of human activities.2. Most of these polluting matters are solid and contain organic matters, nutrients and heavy metals in a high concentration. This phenomenon cannot be ignored in order to conserve natural environment.3. For the prevention of pollution of water environment, trial to lessen the deposits from the urban activities, partial gathering and treatment of polluted snow and pollution control of the land for piling up the snow gathered from the streets are necessary.4.

在北方地区，降雪和堆雪的污染及其对自然环境的影响已成为严重问题。雪和雨在空中落下时受到污染，落在地面上则受到人类活动产生的有害物质的污染。这种受污染的雪在春季融化时间很短，对环境特别是水质造成影响。事实上，富营养化和有机物质、重金属污染是存在的。本研究正是在认识到上述事实的基础上，旨在明确雪地污染的实际情况和污染机理，并提出一些污染控制方法，以达到控制水环境的目的。研究发现；1．地面积雪受到大量道路扬尘和人类活动废弃物的严重污染。2．这些污染物大多为固体，含有高浓度的有机物、营养物质和重金属。为了保护自然环境，这一现象不容忽视。3．为防止水环境污染，应尝试减少城市活动沉积物、污染雪的部分收集和处理以及街道积雪堆放用地的污染控制。 4．其他的
