Indlela ukumisa kunyebeleziso bevala ukugcina iimpawu zendalo zomhlaba?

Bevala zisisiphumo kwamanzi kunye nokhukhuliseko lomhlaba kwaye engeke ukukhropha amazwe. Indlela ukumisa kunyebeleziso kwizihlambo yintoni na onokuyenza ukukhusela umhlaba emfundweni yazo, funda inqaku.

nemiwonyo primary

Bona akhiwa ndawonye emanzini amdaka kwenye izinto network ukwakweli kwithambeka lokuthathwa amanzi, oku kube umqadi. Kulo mzekelo, amanzi abetheka phantsi azalise imvelaphi ezenziwe ukuba wakha umntu.

Kuqhubeka ntoni? amanzi ukufikelela elunxwemeni umqadi, enokubangela ukuba exandekeni. Ngenxa yoko, ukuhamba oyinhloko abunjwe udonga, ekwabizwa ngokuba elunxwemeni. Ezi bevala ukuphuhlisa ekugqibeleni eyaziswa ethambekeni eedreyini. Kulo mzekelo, ithambeka kwasekwa bevala.

ezase Primary: Inqanaba lophuhliso

Bevala elolu hlobo benziwa ngokuthe ngcembe. Le nkqubo yahlulwe manqanaba alandelayo:

• Okokuqala, xa kuyilwa bevala ukuya iisentimitha amahlanu ngokunzulu. Uphawu Uphawu kuba phambi inkangeleko phezu emazantsi ethambekeni. Icandelo umnqamlezo udonga yi unxantathu okanye trapezoid. zomhlaba olinyiweyo kunye nomhlaba evakalala ngokukhawuleza kakhulu siphantsi kwenkqubo enjalo, iminyaka malunga enye ukuya kwezintathu.

• Kulo lesibini inqanaba enekona evulekileyo kwakhiwa. Oku kungenxa ukhukuliseko ngokukhawuleza unxweme umqadi. ukuqhubeka Ground uhlambe kude ukuhamba kwamanzi, apho eludongeni siyabutyaka. Athwala phezu komhlaba. Breakage ungaba kuze ezilishumi ubude. Line profile phakathi.
• Inqanaba lesithathu luphawulwa isizukulwana profile kuvuselele. ekuqaleni kwayo ibhekisa kwinqanaba ngokunciphisa umlomo kumwonyo ukuya kwinqanaba kumazantsi umqadi. Ravine kwandisa ubukhulu.
• Xa inyathelo elilandelayo yokukhula udonga kuyehla: iqala ukuvelisa iprofayile kuvuselele. Emazantsi akwenzeki ngaphezulu ngenxa bajongelwe phantsi kwamathambeka liyaqhubeka ukunyusa ububanzi. Xa angle ukuthambeka ivuselelwa umhlaba uba esitalini, izityalo ziya kuvela ecaleni kumwonyo. udonga ukubunjwa lwagqitywa. Indlela ukumisa kunyebeleziso ezingxingweni, funda inqaku ngezantsi.

nemiwonyo zamabanga

Ziye ke benziwa ngenxa yokuba ukukhusele emazantsi nzulu. Ezi ezigodini kuthiwa benthic. Emantloko kwizihlambo bevala kwimigongxo ezininzi. Njengoko baqalise ukukhula nemiwonyo ezantsi, ebizwa exandekeni. imvelaphi yayo ukuthatha kweenxweme yesikali. Ukuya phezulu ithambeka emvula zixhaxhwe. Ezi ezigodini kuthiwa kwithambeka eziziisekondari.

ezigodini kwamahlathi

Xa sidibanisa indlela ezigodini abantu baqala kudala, emva kwinkulungwane yeshumi elinesithoba. Indlela ukumisa kunyebeleziso kumwonyo? Qhoboshela phezulu nasezantsi wayifulela usebenzisa umgquba okanye izityalo willow nemipopulari. Ukuze agwejelayo endulini akazange kuphuhliswe ngakumbi, kufuneka ukuba uphephe, ukukhusela umhlaba kukhukuliseko. Indlela ukumisa kunyebeleziso kumwonyo? Ukuze wenze oku, uyacebiswa ukuba ndilutyale shelterbelts.

Baya komeleza phezulu nasezantsi kumwonyo. Ungasebenzisa ezayame ezahlukeneyo kunye nokwakhiwa eziphathekayo. izithintelo zendalo nqwelo yehlathi ukufunxa amanzi agqithisileyo, apho udonga lunqunyanyisiwe ukukhula. Imithi ityalwa kumgama oziimitha emithathu ukuya kwemihlanu ukusuka elunxwemeni kumwonyo.

Unokuyisebenzisa njani ukukhusela umhlaba ukuyilwa bevala? Imithi, zawo ukukwazi ukubophelela umhlaba. Kodwa khumbula ukuba iingcambu ukufunxa ukufuma komhlaba kuphela. Ngokusebenzisa iingcambu zomthi udlula ngokukhululekileyo umlambo kanzulu zolwelo. Khumbula ukuba inkqubo ingcambu bangakwazi ukunika ukhuselo, njengoko iingcambu zesityalo kusikwa noko benjalo, umhlaba kunye nemithi utyhala wehla waya ezantsi kumwonyo.

ukhukuliseko lomhlaba

Xa imijelo yamanzi ikhephu isehla nasemaxandekeni, zihlanjwe nihle umhlaba zinyibilikisiwe kuvela bububi bobuso, kwaye sisiqalo ukubunjwa ebisenyobeni abakwaziyo ukutshabalalisa amasimi ezilala phezu endleleni.

Ezabanjwa amathambeka bubunile utyani - imeko olukhulu imbonakalo bevala. Indlela yokukhusela umhlaba ukuyilwa bevala? Ukuze wenze oku, ukudala i mifuno yezityalo elungileyo, engakuvumeliyo ukubonakala kwazo kwaye yandisa imveliso yelizwe.

Inkqubo ikhuthaza ukuyilwa sokhukuliseko bevala umoya ngexesha ezinyukayo uthuli, intlabathi, umhlaba. Konke oku yokugoqoza phezu babeziindleko ububanzi kwaye luhlala phezu komhlaba. maxa wambi intlenge ukufikelela eziimitha ezintathu ukuphakama, etshabalalisa izityalo. Wind ezikhule umhlaba ezingamashumi amabini anesihlanu neesentimitha nzulu yaye uya ukuya kumgama ozikilometa ezintathu, nto leyo izinto zomhlaba ngoomatshini afuthe. Ukwenziwa bevala mizila - harbingers ze nemiwonyo. umhlaba yezolimo ngoko bobabo kudidi lingavumi, nzima unyango umhlaba.

Ukhukuliseko kwenzeka imbalela lomhlaba, ziyonakala iimpawu ezibonakalayo umhlaba, umsebenzi wabo lomzimba lifinyele, oku kunciphisa imveliso yezityalo olinywayo. Indlela yokukhusela umhlaba ukuyilwa bevala? Kuyimfuneko ukuthintela ukwenzeka lokhukuliseko lomhlaba. Ukusetyenziswa kwe yesityalo yolondolozo lomhlaba, agroforestry kunye imisebenzi yezolimo ukunceda ekunqandeni ukhukuliseko. Oku kunegalelo ekwakhiweni kwezakhiwo hydraulic.
