瑞典人酷爱大自然的一种“情结”令人感叹!瑞典450万平方公里国土中有220万平方公里被森林所覆盖。由于森林资源特别丰富,其造纸、造船及家具等行业尤为发达。在这个国家,森林是不可随便被砍伐的。要砍伐得按计划进行。或许是为了保持本国的森林资源,他们为此立下的种种法规,可谓缜密而严苛。在非森林砍伐区内,谁要是无端剥损一块树皮、折断一根树枝、采摘一片树叶,都将会被视作违法行为而受到重罚。瑞典的水力资源十分丰厚。有勘测数据表明,该国陆地湖泊达万余个,在世界上被誉为“万湖之国”。瑞典的海岸线也特别长,整个东部及南部均被波罗的海所包围,人均耕地面积不足半分地,但他们不像有些国家因此而毁林垦荒,围海造田,以牺牲大自然的美丽来换取瓜果粮油的丰收。在本世纪初,他们就发现湖泊存在干涸的危险,有关科学家就开始从事湖泊生态的研究。为了防止湖水自然缺钙的问题,他们竟用飞机向湖水中撒播各种补钙物;而为了将湖水里的繁杂藻类作彻底的清理,他们还发明了一种很科学的除藻机械,只要用装置这种机械的船只在水面上缓缓驰过,那转动的机械就会把湖中的杂藻连根拔除干净。
Swedes love nature a “complex ” sigh! Sweden 4.5 million square kilometers of land 2.2 million square kilometers of land covered by forests. Due to the particularly rich forest resources, its papermaking, shipbuilding and furniture industries are particularly developed. In this country, forests can not be deforested. To cut according to plan. Perhaps in order to maintain the country’s forest resources, the laws and regulations that they have laid down for this purpose are meticulous and harsh. Anyone in the non-deforestation area who has unjustly stripped a bark, broken a branch, or picked a leaf, will be punished severely for being considered illegal. Sweden’s water resources are very rich. Survey data show that the land lakes in the country up to more than a thousand, in the world known as the “Lake Country.” Sweden’s coastline is also exceptionally long. The whole of the eastern and southern parts of the country are surrounded by the Baltic Sea. Per capita arable land is less than one-half of the land. However, unlike some countries, land is deforested, land reclaimed from the sea, and fruits are sacrificed for the beauty of nature The harvest of grain and oil. At the beginning of this century, they discovered the danger of the lake drying up and scientists started to study lake ecology. In order to prevent the natural calcium deficiency in the lake, they actually used airplanes to spread various calcium supplements into the lake. In order to thoroughly clean the complex algae in the lake, they also invented a very scientific algae removal machine as long as With mechanical devices such as boats slowly over the water, then the rotating machinery will be the lake’s algae removed by root.
