Udzu ndi mitengo ya Europe ndi ku Asia, Africa, North America ndi South America

Udzu ndi mitengo zimapezeka zambiri mu mabacteria subequatorial. mabacteria amenewa akupezeka hemispheres onse. Koma m'madera savannah angapezeke mu mayiko kotentha. zone Izi amakhala ndi zinthu zingapo zochititsa. Nyengo mu savannah nthawi nyengo yamvula. Pali kusintha bwino mu nthawi ya chilala ndi mvula. Ndi kayimbidwe kotani nyengo amasankha njira zonse zachilengedwe. Kuti mitengo ndi savannahs ndi khalidwe ferralitic nthaka. Zomera zosapezekapezeka mabacteria izi, ndi magulu osiyana a mitengo.

savannah nyengo

Savannah ndi mitengo ndi zinthu nyengo. Choyamba, zikuonekeratu, rhythmic kusintha kwa nyengo ziwiri ya chilala ndi mvula. Aliyense nyengo, zambiri kumatenga miyezi isanu ndi umodzi. Kachiwiri, chifukwa savannah kusintha khalidwe la mpweya misa. M'madzi kunyanja akubwera mu Rute wa otentha youma. nyengo nazonso anakhudzidwa ndi pafupipafupi mphepo yamvula. Iwo amabweretsa pa mvula nyengo. Savannah pafupifupi nthawi zonse lili pakati pa youma mabacteria ya zipululu ndi chinyezi nkhalango yamphamvu. Choncho, mitunda izi zonse kumva chikoka cha mabacteria ndi awiri. Nkofunika kudziwa kuti chinyontho likhalebe motalika kokwanira m'magawo awa. Choncho, sizikula nkhuni zakhala zikuzunza m'miyoyo. Koma yochepa yozizira nthawi musataye savannah inasanduka chipululu.

udzu nthaka

Pakuti udzu ndi mitengo yodziwika ndi predominance wofiira ndi zofiirira, komanso maphatikizidwe wa nthaka wakuda. Akusiyana zili makamaka otsika humus misa. Nthaka ano zimalimbikitsa zapansi, kotero pH awo ali pafupi ndi ndale. Iwo sali chonde. Pansi pa ena Mbiri angapezeke concretions chitsulo. Pafupifupi chapamwamba zadothi mosungiramo mphamvu ndi za 2 mamita. montmorillonite mdima yofiira nthaka amapezeka mu kuchuluka kwa dothi red-bulauni mu malo matendawa, chithandizo. Nthawi zambiri ma oterewa tingawapeze mu malo okwera Dean kum'mwera kwa izo.

Savannah Australia

Udzu ndi mitengo ya Australia zatenga malo ndithu Chile. Iwo ankaganiza kumpoto m'dzikoli. Iwo zatenga malo aakulu pa chilumba cha New Guinea, nalanda pafupifupi buku lonse kum'mwera gawo. savannah Australia ali kusiyana kwake. Alibe African kapena American South. Nthawi ya mvula m'gawo lake lonse yokutidwa yowala zomera maluwa. Iwo chimakhala chogwidwa ndi buttercup banja, maluwa ndi duwa. Komanso, mbewu ndi amapezeka m'dera limeneli.

Pakuti savannahs ku Australia ndi khalidwe la zomera zake. The bulugamu choyamba, casuarinas ndi mthethe. Amaika magulu freestanding. Casuarinas masamba chidwi kwambiri. Iwo wapangidwa ndi zigawo munthu ndi amafanana singano. M'dera lino, monga palinso mitengo chidwi ndi mitengo ikuluikulu yambiri. Mwa iwo, iwo kudziunjikira chinyezi zofunika. Chifukwa cha khalidwe ichi, iwo amatchedwa "mitengo botolo". Kupezeka kwa zomera achilendo ndipo zimapangitsa Australia savannah wapadera.

m'tchire African

Udzu ndi mitengo mu Africa kuchokera kumpoto, kuchokera kumalire a kummwera nkhalango zotentha. Nature pano ndi wapadera. M'nkhalango borderland pang'onopang'ono woonda kunja, kapangidwe awo amasandulika chimaonekadi osauka. Mwa mosalekeza woodland m'tchire malo akuwonekera. asinthire zomera zimachitika chifukwa kuchepetsa mvula ndi youma nyengo kuwonjezeka. Monga mtunda kuchokera woyendera nthambi kunyanja, chilala kwayamba yaitali.

Pali maganizo bwino chosakayikitsa kuti kufalikira yotakata udzu mkulu-udzu, zomwe m'malo mwa deciduous ndi yobiriwira nkhalango wosanganiza, n'zogwirizana ndi zochita za anthu. Pakuti ndithu nthawi yaitali mosalekeza anatentha zomera m'madera amenewa. Choncho panali mofulumira mosalephera za ubwenzi wa wosanjikiza mtengo. Izi zachititsa kuti afike mayiko amenewa ng'ombe lalikulu la nyama hoofed. Chifukwa, ayambe zomera zake wakhala zosatheka.

Udzu ndi mitengo ya Europe ndi ku Asia

Mu Europe ndi ku Asia udzu sizichitika kawirikawiri. Zimapezeka yekha zambiri India. Komanso mitengo angapezeke pa dera la Indochina. Mu malo awa yamvula nyengo ponseponse. Mu savannahs European makamaka kukula kopanda mthethe ndi kanjedza mitengo. Zitsamba zambiri mkulu. Nthawi zina mungathe kupeza yamawangamawanga wa nkhalango. Udzu ndi mitengo ya Europe ndi ku Asia amasiyana African ndi American South. nyama Main m'magawo awa - ndi njovu, akambuku, antelopes. Komanso pali kuchuluka kwa mitundu yosiyanasiyana ya zokwawa. m'madera nkhalango kawirikawiri ankaimira ndi mitengo deciduous. M'nyengo youma iwo anakhetsa masamba awo.

Udzu ndi mitengo ya North America

savannah malo North America sipanatenge monga ambiri monga ku Australia ndi Africa. mipata Open mitengo wotanganidwa makamaka dzinthu mitundu herbaceous. Wamtali alternates udzu ndi yaing'ono, minda anabalalika.

Mitundu yofala nkhuni, amene amakhala ndi udzu ndi mitengo ya North America - ndi Mimosa ndi mthethe. M'nyengo yadzuwa, mitengo kukhetsa masamba awo. Zitsamba ziume. Koma panthawi ya mvula savannah pachimake. Chaka ndi chaka malo mitengo zikuchulukirachulukira. chifukwa chachikulu - ndi yogwira ntchito zachuma. Savannah unakhazikitsidwa pa malo a nkhalango kugwetsa. The zomera za m'madera amenewa ndi osauka kwambiri kuposa ena m'dzikoli. Apa pali mitundu ina ya ungulates, pumas, makoswe ndi chiwerengero chachikulu cha njoka ndi abuluzi.

Savannah America South

Udzu ndi mitengo ya America South m'malire rainforest. Chifukwa cha kusintha kwa nyengo, zomwe zimagwiritsa maonekedwe a nyengo yaitali ya chilala, malo awa mu wina ndi mnzake. Pa malo okwera a Brazil mu gawo lalikulu ili m'tchire. Iwo ankaganiza makamaka hinterland lapansi. Pano mukhoza kupeza Mzere wa nkhalango kwenikweni koyera kanjedza.

Udzu ndi mitengo komanso zatenga malo aakulu mu Orinoco otsika. Iwo ali mu madera a Guiana okwera. Mu Brazil, kuposa m'tchire lililonse lotchedwa "Campos". zomera akuyimiridwa mu mitundu zambiri monga chimanga. Komanso, pali ambiri a banja Asteraceae, ndi nyemba. mitundu Wood zina kwathunthu kwina. M'madera ena akadali zotheka kukakomana ndi m'madera akumidzi a m'nkhalango yaing'ono Mimosa. Koma pali kukula treelike cacti, Euphorbia ndi succulents zina ndi xerophytes.

Brazil Caatinga

Udzu komanso nkhalango kuwala kumpoto cha Brazil anapereka nkhalango ochepa, amene kukula zitsamba makamaka chilala zosagwira ndi mitengo. malowa amatchedwa "Caatinga". The dothi ndi pabuka-bulauni. Koma zambiri zosangalatsa dzina mtengo. Mu nyengo yadzuwa, ambiri a iwo kukhetsa masamba, koma pali mitundu ina kuti adzatupa thunthu. Ndi zomera amasonkhana okwanira kuchuluka kwa chinyezi. mitundu zimenezo zimaphatikizapo Mwachitsanzo milkweed. Mitengo yokutidwa ndi mipesa Caatinga ndi ena zomera epiphytic. Anapezeka m'maderawa, ndi mitundu yambiri ya kanjedza. Wotchuka wa iwo - ndi carnauba phula. Kuyambira lero sera masamba analandira.
