Eliphansi ezinabantu dissected yimifula, okwenza kube inhlabathi efanelekayo ukusetshenziswa yezolimo. Ngokuyisisekelo ezindaweni eningizimu-asempumalanga. Kodwa enyakatho sendawo kuyinto amanzi kakhulu. Eliphansi iyona esigodini somfula La Plata.

isikhundla ezindawo

Eliphansi welulela bebheke meridional kuyinto 2 400 km. Kuzoqalwa nge-ngumgogodla zwekazi eningizimu ivinjelwe. Enyakatho, entshonalanga futhi ngokwengxenye izungezwe semi ehlane esifundeni Gran Chaco, enyakatho-mpumalanga ubhekene Brazilian Highlands. Esikhathini eningizimu naseningizimu-mpumalanga umfula iRío de la Plata Basin ifinyelela imingcele emaqeleni South America - pampas. Entshonalanga it is izungezwe i Precordillera esifundeni.

sici

Eliphansi endaweni elalihlala mazwe alandelayo: Brazil, Paraguay, Uruguay, Bolivia futhi Argentina. Le ndawo itholakala ku umcengezi aseningizimu yeNingizimu American Ipulatifomu ukuthi ihlinzeka imvelo owendlalekile isimo sezwe. Isilinganiso engamamitha iRío de la Plata Basin - 0-200 m ngaphezu kolwandle. Kuphela, esenyakatho-mpumalanga ukwanda impumuzo kancane, ukwakha amagquma encane eyodwa futhi amagquma.

Ngokusho ehlanzeni imifula emikhulu - Uruguay, Iguazu futhi Parana. Awela esizalweni somfula we La Plata. Insimu, okuyinto kukhawulwe emifuleni, ebizwa ngokuthi i-Argentina eMesophothamiya. Ukusakaza amanzi ageleza phezu endaweni, yakha ezijulile izigodi, nezimpophoma Rapids.

izici zezulu

Lokhu elisezansi lesemkhatsini wa nakwezifudumele futhi ezishisayo nesimo sezulu esishintshashintshayo. Isimo sezulu kanye nomswakama kwasithinta kakhulu emoyeni mass ivela Atlantic. Lina incipha ukusuka empumalanga uya entshonalanga. avareji yonyaka kule ndawo 1 000-1 200 mm / g. lokushisa esijwayelekile ngaphakathi kobubanzi +22 ... + 24 ° C - ngoJanuwari (ehlobo eningizimu nenkabazwe) no-10 + ... + 15 ° C - ngoJulayi (eningizimu nenkabazwe ebusika).

Phakathi nenkathi ehlobo imimoya enyakatho kukhona ohlabayo hot. Bona abalethe ukuhwamuka futhi esiphezulu lokushisa emoyeni ukuthi ngezinye izikhathi ukufinyelela +45 ° C. pampero eziletha frost (-5 ° C) - isiphepho wendawo wind ngezikhathi ohlangothini lwaseningizimu ye-Antarctic ensimini ukungena. Lezi uquqaba esemoyeni esikhathi esifushane. Engavamile, kuba isikhathi frost ehlanganiswa iRío de la Plata Basin. Yini isimanga kangaka? Kodwa cabanga ukuthi lezi zindawo, ngokungafani eRussia, pheze ungalokothi abandayo!

izindawo zemvelo

Nature Area iRío de la Plata Basin iyafana asemaqeleni. Izitshalo zinokuphila okunempilo kuyinsakavukela unyaka wonke, njengoba isikhathi eside nesithwathwa endaweni alikho. Esikhathini eningizimu ubuswa enkangala. Enyakatho kukhona ehlanzeni endaweni izimbuku planethi - the Pantanal. Kuyinto ukucindezeleka zomhlaba, endaweni ingqikithi 150 sq. M. km kanye m 50 ngaphezu kogu lolwandle. Marshland ezakhiwe overburden emifuleni njalo ngobukhulu, okuyinto dissected ngu iRío de la Plata Basin. Ebalazweni elingezansi ungase ucabangele ngokuningiliziwe izici indawo endaweni.

On imingcele enyakatho-mpumalanga yesifundazwe elisezansi sihamba endaweni yemvelo kwamahlathi kanye nasemahlathini. Ngakhipha ke, izihlahla ikakhulukazi siluhlaza, ezihlukahlukene Creepers, bamboos nezihlahla (the izihlahlana ezivamile esifundeni - itiye Paraguay). Ngaphezu kwalokho eningizimu, izimila wezamahlathi ngokuphelele sithathelwe indawo wokudla.

pampas

Isifunda evumayo kakhulu iRío de la Plata Basin kubhekwa eningizimu-mpumalanga. Le ndawo elalihlala asemaqeleni izindawo - Pampas. Lapha, kukhona nenhlabathi evundile grey ansundu. Izwe ngenkuthalo esetshenziselwa izivuno aklaba nokusanhlamvu (kakolweni) nommbila. Kule ndawo kukhona amadlelo ngobukhulu.

Ngenxa Ukungenela komuntu kule ndawo siye sashintsha ngokuphelele nezilwane. Sezadlula izinhlobo eziningi abameleli ungulates, izinyoni ukuthi wayeke wahlala endaweni. Izakhamuzi Animal kule ndawo babekhuthele namagundane kuphela.

Ukusebenzisa izindawo

IRío de la Plata Basin amakhulu eminyaka isicabha, ngakho izimila bomdabu ishiywa. Landscape kabusha ngokuphelele.

Inguquko kusuka ehlobo ebusika endaweni azinakwa. Lokhu esikahle kwenza kube nokwenzeka unyaka wonke yokusebenzisa umhlaba wezolimo. Iningi ngokwemvelo eniselwayo kubhekwe esempumalanga esifundeni. Lokhu lula emfuleni Parana, Uruguay nemingenela zabo eziningi. Entshonalanga iRío de la Plata Basin uya woma. Inani lamanzi notshwala kakhulu ukubuyeka, zinjalo kwesizini.
