Geography lesson in grade 8 Teacher: Shvetsova V. A. Plant World of Russia

Purpose: get acquainted with the diversity of the vegetation world of Russia. Tasks: 1. To find out the causes of the diversity of the vegetation world of Russia. 2. Determine the morphological and physiological signs of plant fitness to the environment of their habitat. 3. Determine the value of vegetation in nature and for humans.

The vegetation "face of the landscape" of the food for animals and man supporting the level of groundwater raw materials for industry formation of the gas composition of the atmosphere vegetation - one of the most important components of nature

Tundra is a little heat, a short cool vegetation period, permafrost, winds. Mossi, lichens, cloudberries, dwarf Bereza, Iva. Roots in the surface layer of soil, peeling, pillow-shaped, small leaves, lowerness, perennials. 2. Forest warm summer, winter from a snowy moderate - cold to harsh, excess moisturizing, eternal Merzlot. Coniferous acidic and small-scale species of trees. Trees are discharged by foliage, larch dumps a cheva for the winter, her roots in the surface layer of the soil. 3. Steppe Cold Winter, Warm Summer, Insufficient Moisturization.

The abonal type of vegetation is the type of vegetation that does not form a solid cover within the plain part of the natural zone (for example: plants of meadows, swamps, wood forms of plants in the floodplains of the rivers of the flameshed natural zones). Types of vegetation The zonal type of vegetation is the type of vegetation forming solid cover within the equal part of the natural zone (for example: forest, steppe type of vegetation).

Why are different plants within one state - Russia?

Factors affecting the diversity of the vegetation world of Russia geographical position; climatic conditions territory (heat and moisture); relief and the composition of surface deposits; depth of groundwater; Features of soil; Human activity.

Fastening the material studied. Packaging shape, a curved trunk of trees, small leaves. For which natural zone are characterized by listed fixtures of plants? Find an excess plant and emphasize it. Pine, oak, birch, saksaul. Find a pair (pair connect the arrow). Tundra Food Steppe Yagel Forest Kovyl finish Proposal. A decisive factor that affects the formation and distribution of zonal vegetation types is - ___________________. Insert the pass. The absence of trees in the steppe is due to the insufficient _______________, and in the tundra disadvantage __________________.

Homework. 1. Paragraph 18, p. 100 - 104; 2. Oral answer to the next question: Pay attention to the drawing. "When entering the forest, we can see mushrooms under the trees: under the birchings - subbootoviki, under the aspen - the boomines. This is a special type of relationship of organisms - symbiosis. But there are mushrooms in nature just below the trees. Explain where you can observe such a phenomenon, and what is the reason? "

Slide 1.

Arctic desert "Country of Ice and Darkness" (F. Nansen) Back "Arctic" translates like a bear. The natural zone is located behind the northern polar circle. Hurricane winds, polar days and nights, low temperatures, do natural zone Unsuitable for habitat many plants.

Clade 2.

Tundra Tundra has the origin from the word "Tunturi", which translated from the language of the sami means "hills" - low vertices that are not covered with forest.

Slide 3.

Taiga Taiga called coniferous forestsCommodified south of the tundra. These forests go a continuous strip from the western borders of Russia to Eastern Siberia, occupying most of the forest zone.

Slide 4.

Arctic desert vegetation does not form solid cover. Separate spots of lichens, individual plants stems are replaced with bare parts. Zone arctic desert It takes insignificant loskutki rocky sushi, for a short period of exemption from snow on the islands and on the mainland (it is only a narrow border adjacent to the outskirts of the tundra in the north of Taimyr).

Slide 5.

Tundra plants tundra adapted to short fly, proximity to marzlotes and soil wettres. All plants are low, many of them are stealing on the ground, almost all plants are small, pubescent, "felt" leaves. Many plants in the tundra winter in green and under the snow! IN short months Summer Tundra turns into a floral and berry garden. She is shot by bright rusties of petals, lights are glowing beads lingers, cranberries, clouders, pigeon dear blueberries.

Slide 6.

Taiga in the field of taiga spread the climate is warmer than in the tundra. In the European part of the country, the taiga is formed by most of the fir tree and the ordinary pine. In Western Siberia, there are fir, pine, spruce. Eastern Siberia consists of larch and pine. On the Far East There are coniferous-wide forests.

Slide 8.

Mixed forests "... And here in the lane mixed, the disgusting of the oak is softened, the oak nodesiness is smoothed by the softness of the needles ... Soft, gentle forest. The fir grows next to the oak, the medical school string was tesled over the pine forest with a suspended vertex, the sharpness of the maple and the rounded Lipa appeared, waved his centened leaves, the aspen was injured ... "N. Mikhailov

Slide 9.

Wide forests Bolitary forests occupy a narrow strip between mixed forests And the forest-steppe in Russian plain, there are found in the Far East in the zone of sufficient moisture, on the brown forest soils, the zone of large forests is located.

Clade 10.

Wide forests are bright representatives of the zone of broad-breeds are thermal-loving and deciduous rocks: oak, beech, maple, grab, linden ... Wild forests are distinguished by the wealth of trees and shrubs. Wide trees have a rather large plate sheet. Such a sheet evaporates a lot of water.

Clade 11.

Steppe products are mild and subtropical belt spaces covered with herbal vegetation on chernozem and chestnut soils. In Russia, the steppes are located in the south of the European part of Russia, in the West Siberian Plain and places in the belt of the mountains of Southern Siberia.

Slide 12.

Typing flags covered with herbal vegetation. The most striking representatives are Kovyl, Ticachak, Flower - Tulips, Iris, Sage, Dimony Drug.

Slide 13.

The deserts and semi-deserts this zone is characterized by extreme aridness and continentality of climate, saline soils and discharged float cover. In Russia, this area is located in the Caspiani and East Predocent.

Slide 14.

Desert and desert semi-deserts are distributed in those areas where the climate is still land and hotter than in the steppes. Solid cover vegetation does not forms. Plants are well adapted to droughts and salted and sandy soils. Bright representatives - Camel Kolya, Saksaul, wormwood, Solyanka.
