Savannah: aina, kanu a me nā holoholona. He aha soils predominate i loko o ka savannah?

Savannah - he maoli wahi me ka predominance o herbaceous kanu ma ulaula lateritic soils. Kēia ciia maoli luna '(PC) ua māhele ma waena o ka ua nahele a me kalaka nui-nahele no hoi ia. Over 40% o Africa ka wahi ua ku e nui aouli o ka savannah. Soils e hana ma lalo o ka lepaʻano kiʻekiʻe kanu me ka predominance o kiliala, lāʻau a me ka pohihihi nui o nā lāʻau kukū laau uuku.

Tropical nahele hehi

Savannah, koe Africa, i pono ole ma Australia a me ka Mauna subcontinent. A hiki i kēia 'ano e pili ana PC campos Llanos, a ma luna o ka pelapela a oʻAmelika Hema. Pinepine hoʻohālike me ka savanna nahele-hehi o ka pakiko ciia o Eurasia. Aia nō kekahi mau mea like, akā, ma laila nō oi oko ao. I ka papa kuhikuhiE hiʻona i emi iho Savannah:

• aina me ka haahaa humus maʻiʻo;
• xeromorphic herbaceous kanu;
• laau a me ka laau uuku me ka umbellate leialii;
• waiwai a me nā aaoa (e like hehi, ka mea, ua malamaia).

Campos - Palakila savanna plateau - i hanaʻia ma nāʻano o ke kanu ka noho 'ana. Cerrados ua wehewehe aku ma ke alo o nā lāʻau haʻahaʻa-e ulu ana a me ka laau uuku. Limpos pepa loloa hehi. Llanos ma na aoao elua o ka Orinoco muliwai i uhi ma South America me ka mānoanoa ka mauʻu, a me ka kanaka hui o nā lāʻau (nā lāʻau pāma).

ʻApelika Waena savannah. Aina a me ka huliau

Tropical nahele kahi e kaili ia ma luna o ka wela'āinapuniʻole, ma kahi o 40% o ka ?? eoi? Ee.
I ka (Northern hemisphere) savannah loaa ole semideserts ma ka latitu 16-18 °, pili like ia Lake Chad a me granulated kōpaʻa. Palena o ka ciia o ka PC a hiki i ka aoao hema o ke koaʻe ke o Capricorn. Savannah papu hoopiha makahiki, a ala hou ana i ka nui kiekie i loko o ka EastʻApelika Waena plateau.

Ke predominant ano o ke aniau - iiaciiie-Kapikoowāea a me ka Tropical. He maopopo distinguishable ma ka makahiki elua kau - pulu a me ka maloo. ua hoemiia ka ke anuenue wa ka wā e haʻalele mai Kapikoowākea a hiki i ke koaʻe ke mai 7-9 i ka 3-4 mahina. I Ianuari, i ka wa a ka mea, o ka wai manawa i loko o ka (Northern hemisphere), i loko o ka Hawaiian arid huli no. Huina ona mau kīnā 800-1200 mm o / makahiki. moisturizing ololi - emi o 1 (lawa kimu). E hoʻokaʻawale aʻe'āpana e ae, mai hiki ole no ia i ka waiʻai ana (K _uvl ma lalo 0,5-0,3).

He aha 'ano o ka aina ma ka savanna ua hanaʻia i loko o ia i ka huliau? Ma ka ke anuenue wa pono, e holoi ka mahuaola intensively me ka wai i loko o ka lalo lipolipo. I ka ia ka maloo manawa, he mea ka e ku pono ana kŰia - lepo pāʻoihanaʻilikai.

kanuʻano a me ka huliau

Ma hope o ka loaa ana ona mau, Tropical nahele-hehi ma Africa ola ana. Yellow-eleele malu maloʻo lalo iho i auou caiaiai ia e ka omaomao'ōmaʻomaʻo. Ulu i ka lau ma luna o nā lāʻau a me nā lāʻau liʻiliʻi, a hāʻule lau ma ka manawa o ka wi, ka mauu ua hoʻomaka koke'ōʻia, i kekahi manawa, a hiki i 3 mau mika i loko o kona kiʻekiʻe. Aina a me ka flora a me? Aaoa o ka savannah o Africa ua hanaʻia ma lalo o ka aoao o ke aniau. Ke ka mahana kumu a me ona mau hilinaʻi ma ka Geographic 'āpana wahi.

Kokoke i ka lihi o rainforest ke anuenue manawa mau no 9 mahina. Aia ua hanaʻia he poe loihi e-savannah; pūʻulu o nā lāʻau a me nā laau uuku oi aku ka nui. Aia mau mimosa a me nā lāʻau pāma, a hana i nā awāwa o ka muliwai gale nahele. Ka loa hoihoi 'laha' o ka flora savanna - ka baobab. Tree kumu pinepine 45 mau mika ma ka anapuni ihoiho.

E like me ka mamao mai ka equator, a kokoke i na koaʻe ke i ka ke anuenue wa ua hoemi, hoʻomōhala typical savannah. Palena me ka kalaka nui-wao akua āpana ona mau loaʻa 3 malama o ka makahiki. Kanu, a ua hanaʻia ma lalo o maloo rula, pili ia i ka wao nahele type savannah. Ma 50 ° C, ka mea oko a iki mai o ka wao nahele. NorthʻApelika Waena lāhui kanaka i kapa mau maoli mau mea "Sahel", na kanaka o South Africa - "ka laau ooi".

He aha soils predominate i loko o ka savannah

Tropical nahele aina - ulaula-ʻeleʻele waihoʻoluʻu a pau, a haawi mai ia i ka hao i huiʻia. No kēiaʻano wehewehe aku ma ka haʻahaʻa humus maʻiʻo - mai ka 1.5 hiki i 3%. Ka waena hapa o ka pili kekahi i ka lepo ma ka lalo kekahi 'illuvial-calcareous lepoʻalihi moana. Ka luna i oleloia hiʻona i ano o ka HikinaʻApelika, i ka'ākau hapa o ka'Aukekulelia'āinapuniʻole, a me kekahi mau wahi oʻAmelika Hema.

He aha ka lepo i loko o ka savannah hana hilinaʻi nui ma luna o ke 'ano o ka humidification. Ma ka pono hooloihi ae i wā maloo humus accumulates ma muli o ke gradual decomposition o ka mea kanu. More momona ka lepo i loko o maloo savannas o Aferika, a me na steppes oʻAmelika Hema. Ma maʻamau huakaʻi ma luna o kaʻilikai ai 'ole ua hanaʻia, a me ka iwi (paakiki pńpa).

I loko o ka Audio ciia e hina okoa maoli ii iai oko ma ka lōʻihi like maloo manawa. 'āina nā hiʻona a climatic rula haʻalele lākou hoailona ma ke 'ano o savanna kanu.

Ke hoʻohālikelike me ka ferrallitic nahele soils ulaula a me ka melemele o ka Kapikoowāea kāʻei i loko o savannas loaa hou humus. Mahalo i ka wā maloo o ke kali decomposition o ke kanu residues a me humus. Kuwaenaʻano - ulaula ferralitic substrates iaaanu-humid ululaau. Ma lalo o kiliala savannas iʻano nui aia lateritic a me ka ulaula iki-eleele soils. Ma lalo o kēiaʻano o ka maloo maoli 'āpana i hanaʻia ma kaʻeleʻele lepo.

Na? Aaoa o ka savannah

Amazingly waiwai a me nā aaoa o ka Tropical ululaau. Aia nā 'elele o nā mea a pau? Aaoa pūʻulu. i loaʻa i loko o savannahʻai punawelewele, nā moʻo hueloʻawa, nahesa, elepani, Hippo, rhinos, hihiu pokole, sheltering, mai ka wela mai o ka lā a me ka ua.

Ka Mahiai i loko o ka savannah ciia a me woodlands

Nui mau mea o Tropical ululāʻau ma Australia a me America Hema e noho ana no ka mauu nei a me ka mahi o ka pulupulu, kulina, peanuts. I Mauna mahiʻai, Africa i hoʻohana savannas a me woodlands.
