项目摘要

The type of the water circulation of lakes is extremely different by each lake. It is, while there are lakes that the water is seldom exchanged, and there is some a distribution of the water as if like the river on intense lakes. Especially, it is lakes without the runoff river to receive the environmental pollution. "The closed lake" taken up in this study are lakes without inflow and runoff river, and it is lakes which is most easy to receive the environmental pollution superscription description way. Especially the drop acidic product has been made the cause of this pollution in lakes to be a problem than the direct and artificial pollution. Recently, seeing effect has produced that the forest does withering on stalk by acid rain and acidic mist, etc. the increase of the drop acidic product which becomes serious year by year begins to have also appeared in lakes. Especially, a snowfall for winters is stored in lakes in the region with the snow in all basins. This time, also drop aci … More dic product simultaneously, basin. The acidic product in the basin flows into lakes with the spring snowmelt in short time. The acidic product in the basin flows into lakes with the spring snowmelt in short time. As this result, the acidity of lakes inside increases in the spring, and the serious effect in the ecosystem is brought about.In this study, the continual observation was carried out in order to clarify which degree effect drop acidic product gives in water quality of Kirigome Lake and Karigome Lake, Goshiki-numa which is located in Nikko City in Tochigi Prefecture and Hokkaido Mashu Lake, lakes in Izu Islands Mikurajima. As a first step, water balance of quantity of water which flows into each lakes and quantity of water which escapes to each lakes escape was done. And, the spring water which was located around lakes was sampled, and snowfall and rainfall of the catchments were collected and were analyzed, while the water quality is analyzed. Like the above, the water balance of the blockage lake was analyzed, and the material balance of acidic product which in addition, flowed with this from the basin was done, and the buffering capacity of each lake was obtained.Though as the result, the forest damage of the nearby region was also recognized either lakes , the acidification of the lake water body in this region at the 10〜20 unit could not be recognized. However, in the home, lakes put under the more serious environment are not few either, and the continual monitoring study seems to be indispensable. Less

每个湖泊的湖泊水循环类型截然不同。尽管有湖泊，但很少交换水，而且水分布好像像河上的河流一样。尤其是，没有径流河的湖泊才能受到环境污染。在这项研究中，“封闭的湖泊”是没有流入和径流河的湖泊，这是湖泊最容易获得环境污染超标准描述方式。尤其是将滴酸性产物的原因与直接和人工污染相比，这是湖泊中这种污染的原因。最近，看到的效果使森林通过酸雨和酸性雾气在茎上枯萎。尤其是，冬天的降雪存储在该地区的湖泊中，所有低音都降雪。这次，也丢弃了ACI…更多的DIC产品，简称为BASIN。盆地中的酸性产物在短时间内随着春天的融雪而流入湖泊。盆地中的酸性产物在短时间内随着春天的融雪而流入湖泊。 As this result, the acidity of lakes inside increases in the spring, and the serious effect in the ecosystem is brought about.In this study, the continuous observation was carried out in order to clarify which degree effect drop acidic product gives in water quality of Kirigome Lake and Karigome Lake, Goshiki-numa which is located in Nikko City in Tochigi Prefecture and Hokkaido Mashu Lake, lakes in Izu Islands Mikurajima。第一步，已经完成了流入每个湖泊的水数量，并逃到每个湖泊的水数量。而且，采样了位于湖泊周围的泉水，并分析了水质，并分析了集水区的降雪和降雨。像上面一样，分析了堵塞湖的水平，除了从盆地提供的酸性产品的材料平衡，并获得了每个湖泊的缓冲能力。结果，近地区的森林损害也被识别出湖泊的森林损害，要么是湖泊的酸化，要么在10-20个单位的湖泊水体中都无法识别。但是，在家里，湖泊在更严重的环境下也不是很少，而且持续的监测研究似乎是必不可少的。较少的
