River Delta - a ecosystem ezizodwa

Inkoliso yabantu kukuthi, yintoni lo ogudle lomlambo, kodwa hayi zonke, ukucinga malunga nendima ukuba zidlala kubomi zonke iintlobo enezityalo nezilwanyana. Kuthetha ntoni amele? River Delta - ukhandwa neetyuwa ze esemazantsi lomlambo ibekwe kufikelela awo. Amaninzi oko ukungena ngamandla uthungelwano imibhobho kunye namathumbu. Le nelezihlambo wadala a ecosystem okhethekileyo. Delta ufumana igama layo ukusuka kwenye oonobumba be-alfabhethi yamaGrike, nto leyo ekwimo yayo ngamandla embhoxo ogudle yamandulo ezingoonxantathu zeNayile.

Xa inkqubo yentsebenziswano ixesha elide phakathi kwemali umlambo, ulwandle okanye ukuphazamiseka yolwandle, umoya-kwama imisinga, amaza, kunye nomthwalo kusombiwa komlambo nganye zenze ogudle ekhethekileyo, leyo singathatha ukuya ezilikhulu lamawaka ngaphezulu ezikwere zeekhilomitha. In iGanges kuthatha phantse 106 lamawaka macala onke. M. km, lo gama i-Amazon - 100 ophosa square.

Delta kunokuqala amakhulu ngeekhilomitha ukusuka emlonyeni wayo. Delta wabeka phambili eminye imilambo elwandle okanye ulwandle, ngoxa abanye - hayi. Phantsi yempembelelo amakhulu nemilambo ezifana Amazon, Amur, i-OB, taz, iPuri na Delta, kungekhona ngaphaya kunxweme lwabo lweenkobe.

Xa amanzi omlambo onokuxinana efanayo kakhulu ukusuka olwandle, ogudle kuthatha isimo tapered (umz, uNeil). Ukuba amanzi umlambo esisityebi imvula, kuba luthe kwe elwandle, ngoko phantsi kwempembelelo ogudle yayo ezidinga side. Xa mninzi ephantsi imila- umlambo wamanzi akhekha inani elikhulu zakhona imibhobho (p. Mississippi).

Uninzi lwemilambo behlabathi abe Delta kunye (nezikhukhula) Imisebenzi nezikhukhula phambili. Ezi iVolga, uLena, Terek, Severnaya Dvina, Kuban kunye Neva. Uninzi lwemilambo esemazantsi ziye "kakuhle" kunye uhlaza kunye zasendle ezahlukahlukeneyo. Yokuba lokuloba ezibalulekileyo. Izihluma zimelwe imifuno ezahlukeneyo, iingcongolo kunye nomzi womlambo, amatyholo kunye nemithi. Bathanda ukulungisa iintaka kunye neentlobo ezahlukeneyo zezilwanyana.

ukubaluleka akuve lokuchuma komhlaba nokufuma ibekwe ogudle emlanjeni. Kumazwe amaninzi ehlabathini phezu kwabo bakhule inxalenye ebalulekileyo izityalo zolimo. utyani eliphambili kwi emakriweni efumileyo, ibekwe esezantsi kuyo imilambo, ngaba kukho ukutya kakhulu yemfuyo. Nomfula iGanges, iNile, kwiYellow River, iDanube ziinkalo nezolimo olunzulu.

Isilwanyana ke ogudle le Neva River, ujikeleze lonke esemazantsi mgxobhozo kwaye iflethi Neva. Lo mlambo ngoku yahlulwe ibe ngamaqela amabini (imo uphawu): phezulu (umthombo - Ivanovskie Imibundu leyo), 30 km, kunye ezantsi (Ivanovskie imigubasi - emlonyeni), km 44 ubude. In ehlayo (malunga ne-15 km ukusuka emlonyeni) yakha Delta ebanzi Neva enyakazelayo imibhobho iziqithi enemikhono emide kunye nemijelo. Yavele ngenxa yokwanda kunye ebbs amanzi elwandle kwaye phantsi kwempembelelo ugeleza amanzi. Xa ogudle le Neva yeyona siqithi sikhulu Krestovsky, Vasilevsky, Petrograd, i Decembrists. imikhono bawo ezincinane kunye Big Neva amancinci, aphakathi kunye amakhulu Neva. Imisele idumileyo - Dlula, ulwandle, umlobothi wakho, Griboyedov.
