Mathata a tikoloho ea etelang makala ea steppe: bakang le tharollo

Steppe ka lik'honthinenteng tsohle, feela ho ba bitsa ka tsela e fapaneng. Ka sena se seholohali Eurasian libaka steppe ka naha ea Ukraine le Russia, Africa le Australia - lesabasaba Amerika Boroa - Pampas, Karolong e ka Leboea - the Prairie. Empa eng kapa eng eo u bitsa tsamaiso ea tsena tsa likokoana-hloko, mathata a tikoloho ea etelang makala ea steppe ke hoo e ka bang e tšoanang hohle.

ke eng steppe?

Steppe bitsoa lithoteng, koahetsoeng ka joang. Ba ba sebakeng mocheso le libaka tropike ea hemispheres bobeli. A tsobotsi bath tsa masabasabeng le - lebaka la ho hloka lifate. Shelterbelts mona li sutumelletsa artificially.

Liphoofolo le limela

Pele e hlalosang mathata a tikoloho ea etelang makala ea steppe, ho ke ke ho hlokahala hore ho bolella eo liphoofolo le limela li ka fumanoa mona. The limela la steppe e hlahisa mefuta e fapaneng ya k'hapete ea joang. Ka masabasabeng le ntseng le hōla masiba, Myalik, joang, fescue, ovsets le palo e khōlō ea mefuta bulbous.

Liphoofolo ka libaka ea steppe ba haholo-holo bosiu, hobane ba tlameha ho ema ka ntle le matsatsi a chesang. Ke lehae la ho matsa, qothomang ngata, jerboa, lintsu, kestrels, larks. Ho phaella moo, ho na le palo e khōlō ea linoha le likokoanyana. Haufi le tsela, linonyana li fofang ka ho fetisisa bakeng sa ea mariha libakeng tse ling. Limela le liphoofolo li ka botlalo ikutloa mathata a libaka le steppe, 'me, ka bomalimabe, boholo ba mathata ana ke molato batho.

Lisosa tsa mathata a tikoloho

Steppe libaka ka ho phethahetseng loketseng ho mesebetsi ea temo. Monna eo o ile a loketse ho thite le makhulong a tsoang pelong. Empa tšebeliso utloahaleng tsa naha ka potlako haholo deplete matlotlo a bona. mathata a tikoloho ea etelang makala ea steppe lebisa ho timetsoa ha masabasabeng le absorption ea libaka tsena moru le mahoatateng. Beha esita le e khethehileng poleloana e reng - "lehoatata". ho senyeha ha ena tikoloho, ho senyeha ya bokgoni ba yona ba likokoana-hloko.

Ho tloha ka libaka steppe hangata komello le meea e omeletseng, batho ba ile ba qala ha feela ho lema, empa hape le ho nosetsa lipampitšana khōlō ea steppe. Nosetso bitsoa nosetsa maiketsetso tsa mobu. , Built tsamaiso ea nosetso le waterworks ho o fumanela tsona metsi. Sena se etsa hore ho ka khoneha ho hola lijalo tsitsitse, empa se bolela ho sokelang:

• E qala ka ho hlepha tsa naha;
• ho na le mobu o salinization le matamo tlhaho;

Ho sa tsotellehe 'nete ea hore melemo e tlisoang ke lumella moea o halalelang ho nosetsa phahameng moruo temo, ho totisa mathata a tikoloho steppe. Hona ho bolela hore motho o lokela ho nahana ka litsela tsa ho fokotsa mathata a ka.

Tsela ea ho fokotsa tshusumetso e mpe ea batho

Ho boloka sebakeng se steppe, ntshetswa pele mefuta e fapaneng ya mesebetsi. Di ikemiseditse ho fokotsa mathata a ka 'me a tsosolosa le ho leka-lekana tlholeho. Tikoloho mathata a libaka le steppe ba ikemiselitse e latelang:
