Izinkuni - ingcebo emangalisayo, kuyisipho esivela ubunjalo indoda

Tree - lokhu amazing isimangaliso zemvelo. Uma isitshalo aliveli ke izwe lethu wawungeke ube yini thina zijwayele ukumbona. Futhi ukuphila ngokwako njengoba enjalo ngeke akhona, ngoba izihlahla ukukhiqiza umoya-mpilo, ngakho kunesidingo sokuthuthukisa eziningi eziphilayo.

Kodwa bangaki abantu abaziyo mayelana nomuthi? kahle kanjani akufundile kumalungu zakhe, izinhlobo nezindlela zokukhiqiza kabusha? Uyazi ukuthi kungani eziningi izihlahla ekwindla bechitha amaqabunga awo? Futhi kuze kube namuhla, wetfula ososayensi wadida?

Kuyini isihlahla?

Impendulo yalo mbuzo kufanele bazazi ngisho lokuqala ibanga, ngoba indaba ka uhlelo primary school. Izinkuni - uhlobo izitshalo zisetshenziswa, bokuthi okuyinto khona stem bok. Kulokhu, eminyakeni, uye kuphela anda ubukhulu, futhi ingafi ekupheleni kwesizini ngayinye.

Izihlahla zikhule cishe noma kuphi, ngaphandle Antarctica kwezinye izindawo ehlane. Yini kuyiqiniso, ngisho izingxenye ezishisa Zomhlaba embozwe elishisayo, isihlabathi ezingaphili, ungathola oasis esekusithekeni nge emithi yesundu aluhlaza futhi azithele ngabandayo ezikhulayo.

izinhlobo izihlahla

Ngokuvamile, lolu hlobo isitshalo zingahlukaniswa zibe izinhlobo ezimbili eziyinhloko: coniferous kanye lezihlahla.

Njengoba ungase ukuqagela kusuka igama, conifer - ingenye esesikhundleni esikhundleni amahlamvu tinhlobo letehlukene izinaliti kanye ishq. izibonelo ezisobala izitshalo ezifana kukhona sonwele pine, cypress kanye fir. Iningi AmaConifers - kuyinto zinhlobo siluhlaza.

Broadleaf Kunalokho, ku eziyimpumelelo Amahlumela kukhona amashidi mncane. Nokho, isimo sabo, kuye ngohlobo izinkuni, kakhulu ukushintshwa. Ezimweni eziningi, eyodwa kuphela ngokubukeka kwabo kungaba ncamashi ukucacisa lokho isitshalo basonta.

Kanti futhi, abantu wakhetha amakilasi ahlukene lezo zihlahla ukuthi kukhona yini ukumbuyisa umusa okhethekile. Ngokwesibonelo, kukhona izitshalo evundile ukuthi kutshalwa emasimini, ukuze abuthele kuzo isivuno. Kukhona zilwane ezibalulekile kabani ukhuni isetshenziswa ekwakheni izindlu, zokukhosela, izikebhe ngisho nemikhumbi.

Isakhiwo esihlahleni

Tree - lena indlela eyinkimbinkimbi kakhulu. Ngisho nanamuhla, ososayensi abakwazi ukuqonda ezinye izinqubo ezenzeka ngaphakathi esitokisini. Ikakhulukazi isithakazelo esikhethekile kuzo kubangela i-photosynthesis ngawo-carbon dioxide is ibe umoya-mpilo. Kuyinto uyinkimbinkimbi chemical inqubo ukuthi ngisho baqonde isimo sawo, osokhemisi abasuke bengakakwazi ukusebenzisa ukukhiqiza kabusha ke egunjini lokucwaninga esibhedlela.

Uma sikhuluma uhlaka somuthi, kukhona lula lonke okuningi. It liqukethe izingxenye ezine eziyinhloko: izimpande, isiqu, amagatsha namaqabunga. Ngaphezu kwalokho, ngasinye salezi zici wenza, lwenza umsebenzi walo ohlukile eliyingqayizivele futhi Irreplaceable.

What do etihlahleni ekwindla nasebusika?

Njengoba kushiwo ngaphambili, ezinye izihlahla ahlale eluhlaza lumelele unyaka, kanti abanye balahle amaqabunga kanye ukufika frost kuqala. izingqondo Ngokucacile bebuza wazibuza: "Bakwenzelani na?"

Okokuqala, it is a indlela self-ukulondolozwa nekuchazwa eminyakeni eminingi yokuziphendukela kwemvelo. Into wukuthi etihlahleni ebusika, ngenxa frost, babe ziyaqothuka kakhulu. Lokhu kuyiqiniso ikakhulukazi ngokuphathelene amagatsha amancane eziye kodwa kwadingeka isikhathi baqine. Uma amahlamvu musa ewa ke bayokuwa phakathi eqhweni, ngaleyo ndlela kwande isisindo sabo. Ekugcineni, lokhu kuzoholela yokuthi amagatsha uzoqala ukugoba futhi aphule.

Enye imbangela defoliation kuyinto Ukwehla zonke izinqubo ezibalulekile e ipotimende esihlahleni. Kwakusengathi awela kulala kwasebusika, ozobakhona kuze entwasahlobo. Nokho, ososayensi Namanje asilwazi ngokuqinisekile nini hardwoods naqala ngale ndlela. Kepha softwood zabo 'abafowabo', banayo indlela efanayo ukulala cishe ngokuphelele lingekho.

Izinkuni - ingcebo iplanethi kweqiniso

Ekuphetheni, siphawula ukuthi isihlahla - kungcono amaphaphu iplanethi. Uma ngeke, isintu ngaleso sikhathi kuyoba kungenzeka ufe nabo. Yingakho kubalulekile ukuze wonke umuntu ukukhumbula indima yabo ezimpilweni zethu.

Kufanele kuqashelwe ukuthi njengamanje isibalo izihlahla emhlabeni idlula uphawu 3 trillion. Futhi le nombolo kuyehla eziyizinkulungwane ezingu-15 minyaka yonke ngenxa zifake ukwanda kwezindawo zasemadolobheni. A mkhuba efanayo, ngeshwa, ngaphandle kwesizathu esihle bengayi. Ngakho-ke futhi sethemba ukuthi kahle ngaphezulu abantu esizayo namanje ufunde indlela yokusebenzisa imithombo kule planethi.
