Kunamahlathi amaningi emhlabeni, lapho uhlobo oluyinhloko lwezitshalo izihlahla. Ngokuya ngesimo sezulu nezimo zemvelo, amahlathi ayizinhlobo ezahlukene. Uma izihlahla ze-coniferous zibusa, iyihlathi le-coniferous. Isimo semvelo esinjalo sitholakala ikakhulu ku-taiga yasenyakatho nenkabazwe, nasenkabazwe eseningizimu kuyatholakala ngezikhathi ezithile endaweni eshisayo. Amahlathi aseTaiga abizwa nangokuthi isizungu. Zitholakala eNyakatho Melika nase-Eurasia. Izihlahla zikhula lapha endaweni ebandayo enesimo sezulu emakhazeni.
Phakathi kwezindawo zemvelo ezihlanganayo, iMeshchera Lowland kufanele ihlukaniswe, endaweni lapho kuneGreat Belt of Coniferous Forests. Itholakala eRussia - ezifundeni zaseRyazan, eMoscow naseVladimir. Phambilini, amahlathi e-coniferous azungeze indawo enkulu ukusuka ePolesye kuya e-Urals, kepha namuhla yingxenye encane yale ndawo yemvelo esindile. Amaphayini nama-spruces aseYurophu akhula lapha.
Umsuka wamahlathi e-coniferous
Amahlathi alolu hlobo avela enkathini yeCenozoic ezintabeni zase-Asia. Babuye bahlanganisa nezindawo ezincane zaseSiberia. E-Late Pliocene, ukupholisa kube nomthelela ekwehleni kwamazinga okushisa, futhi ama-conifers aqala ukukhula emathafeni esimweni sezulu sezwekazi, enweba ingxenye enkulu yobubanzi bawo. Amahlathi asakazeka ngesikhathi sokuhlangana. Ngesikhathi seHolocene, umngcele wehlathi le-coniferous wajula waya enyakatho ye-Eurasia.
Izimbali zebhande le-coniferous
Izinhlobo ezakha ihlathi zebhande le-coniferous zimi kanje:
- izihlahla zikaphayini;
- larch;
- isikhunta;
- kudliwe;
- imisedari.
Kunenhlanganisela yezihlahla ezahlukahlukene emahlathini. ECanada nase-USA, ungathola umuthi we-fir ne-balsamic spruce, iSitka ne-spruce yaseMelika, uphayini ophuzi. Ama-junipers, i-hemlock, i-cypress, i-redwood ne-thuja zikhula lapha.
Emahlathini aseYurophu ungathola umuthi omhlophe, i-larch yaseYurophu, umjunipha ne-yew, uphayini ovamile nomnyama. Kwezinye izindawo kunezihlanganisi zezihlahla ezibanzi. Amahlathi e-coniferous aseSiberia aqukethe izinhlobo eziningi ze-larch ne-spruce, i-fir kanye nemisedari, kanye nomjunipha. EMpumalanga Ekude, iSruce spruce ne-larch, i-Kuril fir iyakhula. Onke amahlathi e-coniferous anezihlahlana ezahlukahlukene. Kwezinye izindawo, izihlahla ze-hazel, i-euonymus nama-raspberries zikhula phakathi kwama-conifers. Kukhona ubulembu, ubulembu, izitshalo ezibusayo.
Ngenxa yalokhu, iGreat Belt of Coniferous Forests yindawo yemvelo eyingqayizivele eyakhiwa esikhathini sangaphambi kweqhwa futhi yanwetshwa ngezikhathi ezilandelayo. Izinguquko zesimo sezulu zithinte indawo yokusatshalaliswa kwama-conifers nokukhethekile kwamahlathi omhlaba.
