巴尔干半岛(英Balkan Peninsula)是座很大的半岛,在欧洲各半岛中,按面积位居“老大”,它的南部又是欧洲古文明的发祥地,加之民族林立,所以自古以来,地区性名字很多,但在19世纪前的几千年间,本身却没有一个涵盖全境的统一名称。这种局面一直延续到19世纪初,稍后方有了些变化。 相似文献

摩尔多瓦位于巴尔干半岛的东北部,西面与罗马尼亚隔着普鲁特河相望,其他三面均被乌克兰围绕。普鲁特河是多瑙河最后一条支流,在距离边境线几十公里的上游有一个小镇切尔诺夫策,诞生过二十世纪的一位德语大诗人保罗·策兰。当时这个小镇和摩尔多瓦均隶属罗马尼亚,现在它归入乌克兰的版图内。 相似文献

Skadar Lake,the largest lake on the Balkan Peninsula,is famous for a wide range of endemic and rare,or even endangered plant and animal species.Different anthropogenic pressures have,however,influenced the fragile equilibria of the lake ecosystem,with metal pollution as one of the primary concerns.Therefore,this study investigated spatial distribution of metal pollutants in the water and sediment phase of Skadar Lake,and anthropogenic and environmental factors affecting this distribution.A sieving analysis showed that sediment in Skadar Lake is mainly distributed in the three smallest fractions(colloid,clay and silt).Eleven metals were analyzed in the lake surface and bottom water,and only six of them were detected:potassium,magnesium,calcium,nickel,aluminum and manganese.They were all present at low concentrations.In contrast,sediments contained elevated levels of some metals with concentrations between 28.1-126.8 mg kg~(-1) for Ni,23.6-79.2 mg kg~(-1) for Cr,9.2-36.9 mg kg~(-1) for Cu,199-878 mg kg~(-1) for Mn and 9.6-23.1 g kg~(-1) for Fe.Nickel exceeded consensus-based guidelines for safety towards freshwater dwelling organisms.The organic matter content of the sediment fluctuated between 4.7 and 21.5%.No correlations were found between metal concentrations,organic matter and sediment particle size fractions,suggesting that the latter are not the main factors controlling metal accumulation in Skadar Lake. 相似文献
