Lake Lake (also Ladoga; historical name - Nevo) - Lake in Karelia (Northern and East Coast) and -Leningrad Region (Western, South and Southeast Beach), the largest freshwater lake in Europe. Refers to the pool Baltic Sea Atlantic Ocean. The area of \u200b\u200bthe lake without islands ranges from 17.6 thousand km² (with the islands of 18.1 thousand km²) the volume of the water mass - 908 km³; Length from the south to north - 219 km, the largest width - 138 km

The depth varies unevenly: in the northern part it ranges from 70 to 230 m, in South - from 20 to 70 m. On the shores of Ladoga Lake are located the city of Priozersk, New Ladoga, Schlisselburg in the Leningrad region, Sortavala, Pitkyaranta, Lachdenproje in Karelia. IN Ladoga lake 35 rivers fall, and only one - Neva takes the beginning.

    Flora and fauna

    Northern I. eastern coast Lake Lakes belong to the subzone of average taiga, and southern and western - to the subzone of South Taiga. For the average taiga, the delictic-blueberbickers are characterized without undergrowth, with closer-tremble and solid cover of brilliant green mosses. The South Taiga subzone dominates the dark rocks with the undergrowth, where Lipa, Clain, Ilm are sometimes found, a herbal tier appears with the participation of herbal herbs, and the moss cover is weaker than in the middle taiga. The most characteristic type of forest - spruce-rods.

    In the forecast regularly found 256 species of birds belonging to 17 detachments. On the transit span in the spring and autumn, more than 50 species of birds are marked here. Migration links forbid covers space from Iceland to India and from south Africa to the new land. The most attractive territories for the birds is the southern ligation.

    Here on the span there are swans, geese, ducks, stuffs, seagulls, crags, cranes and shepherds, as well as nesting river ducks, crested blacks, red-headed dums, grooves, stalls, large and medium crumbs, big dereg, herbal, golden rzhanki and others Kulikov, Gray Crane, Orlana Belochprot, Skops, Cobchik, Filin, Bearded Towa, Bolotnaya Owl and a number of other birds

    Slide 15.

    The lake is shipping, is part of the water highway, which is part of the Volga-Baltic waterway and the Belomorsko-Baltic Channel. The most intensive movement of ships is carried out in the south of the lake from the river. Lake Lake, despite the cold even in summer, attracts many vacationers: there are on the lake good beaches From the Neva to the Sviri River.

    Shipping in Ladoga is known since ancient times. In the 9th and 2nd centuries, the water trading path "from the Varyag in the Greeks", connecting the North Russia with South, Scandinavia and the Baltic States with Byzantium. The most intensive transport value of Ladoga acquired in Petrovsky times. On the shores of the lake began to be created by the shipyard, channels are built. The Lake Lake Channels in the early 18th century was associated with the upper Volga. But frequent excitements have long been a huge navigation to shipping. In the mouth of Volkhov, they sometimes gathered to 500 vessels in anticipation of favorable weather. This was the reason for the construction of south Bank Ladoga bypass channels. During the Great Patriotic War Ladoga transportation was the only link between the besieged Leningrad and the country. During the navigation, the carriage was carried out by Ladoga flotilla, and in the winter the road was laid in the ice of the lake, called the "Road of Life". In total, over the blockade of Lake Lake, about 1 million people were evacuated to the rear and 1.7 million tons of cargo were transported. Shipping in Ladoga is known since ancient times.

      Ladoga Lake Problems »Items: Ecology, Biology, Chemistry, Geography. Project goal: to study the degree of water pollution of Ladoga Lake, identify the causes of pollution, to propose measures to improve ecological status reservoir with attracting environmental organizations.

      Work in a team of 6 people. Preparation of Ladoga layout, as a visual manual for ecology lessons, geography. Preparation of theoretical substantiation of the issue (study of the history and geography of the lake, the biological and chemical and environmental aspects of the life of the reservoir).

      1ETAP: Studying special literature, information from the Internet, personal trips to Ladoga, photographing the lake and the surrounding nature. 2Etap: Identification of pollution sources and a description of environmental protection in the territory of the Lake Ladoga (presentation). 3Etap: organization and performance at the city interactive event "Save natural heritage! ", Dedicated to the day of the earth.

      Environmental situation in Ladoga proposed to eliminate landfills in the territory of the Lake Ladoga, set containers. Local enterprises proposed to establish smokers and sewage treatment plants.

      Lake Ladoga about 600 industrial enterprises (Volkhovsky chemical plant, boiler houses, petrochemical production, as well as motor vehicles, burning dumps), including cellulose-paper plants (Feling pulp and paper plant, Svetogorsky and Priozersky (closed in 1986) paper mills) And several hundreds of agricultural enterprises are discarded by industrial drains in the palm and its tributaries. Ladoga is considered to be moderately contaminated with a reservoir, she is assigned III class.

      Volkhovsky Chemical Plant Morozovsky Chemical Plant on Map Okhtinsky Chemical factory

      Chemical plant When the Volkhov aluminum plant was built, no one was disturbed by the problem of Ladoga. Moreover, it was believed that nitrogen and phosphorus are food for algae, therefore, for everything inhabited in the lake. The problems of eutrophism did not think about the problems, but it was Nitrogen and Phosphorus put a lake on the face of death. In the late 80s - early 90s, the Volkhov flow brought in a laugh "WHO", in each liter of which 45 milligrams of phosphates, 12.5 milligrams of sulfates, 0.21 milligram fluorine ... Such a "gift" is able to kill all living things. It is estimated that about 7,000 tons of phosphorus arrive in the lake every year.

      Chemical plant fluoroplastic - polymer material obtained by chemical way. Fluoroplast contains fluorine atoms, making high chemical resistance. The strongest oxidants do not affect it even with high temperatures. Fluoroplast is poorly dissolved or dissolved in many organic solvents, not soluble in water and is not wetted by it. Fluoroplast is designed for the manufacture of products and films with high dielectric properties, resistance to strong aggressive media and operating at temperatures to plus 260 degrees Celsius.

      Factory "Ladoga" Autographic company on the map Mid-Nevsky Shipbuilding plant

      Motor products: Tensystems for the carriage of gasoline and diesel fuel. AutoStars with thermal insulation for transportation of fuel oil, bitumen, oil. Tanks-tanks for the carriage of gasoline and diesel fuel Aluminum-tanks. Aluminum tanks for the carriage of gasoline and diesel fuel.

      Plant Currently, the plant is building a rocket boat, trawls, passenger and work vessels for various purposes and is preparing for the large-scale construction of the new generation of mineral ships. It is the main pollutant of the Ladoga petroleum products.

      Lake Myththiofauna Ladoga Lake is represented by 14 families: Mintophates, sturgeon, salmon, charous, bark, pike, carp, belong, somn, edema, cod, stroller, ocumer and submerser. All kinds and varieties of fish in Ladog are 53.

      Schhers from the northwestern and northern coast Ladoga lake. Until 2009 it was nature Park, A. this moment He is considered to be a national park.

      Right say: do not spit into the well. "Lake Lake will soon be unsuitable for drinking water supply," the head of Ladoga "Vodokanal SPb" says - this is the only source of drinking water supply for St. Petersburg. " And not only for St. Petersburg. In total, it supplies drinking water about 15-20 million people. The draft law "On the protection of Ladoga Lake" has already reached the state Duma for the second time. Archka Ivanovich Kindji. The first Russian painter who wrote the picture of Lake Ladoga in 1873 A.I.Kyujji
