Reclamation daim ntawv thov tso cai rau kom tsim tau ntawm av muab kev pab, uas yog ib yam uas tseem ceeb heev nyob rau hauv txoj kev loj hlob ntawm ua liaj ua teb raws li txhim kho productivity, tsiaj nyeg nog puag, muaj txhawb rau txoj kev loj hlob ntawm cov tshiab nraum los yog suab puam av.

Muaj plaub hom reclamation: reclamation, agroforestry, kulturtehnicheskie reclamation, tshuaj tebchaws reclamation. Nyob rau hauv lem, lawv muab faib ua ntau hom.

Hydroland yog dej, kua, dej nyab tswj, protivosolevoy, anti-yaig, landslide.

Agroforestry yuav ua tau yaig, teb, pasture.

Kulturtehnicheskie reclamation ntawm av yog muab faib mus rau hauv av tshem ntawm cov nyom, ntoo, ntxhuab hummocks, stumps; tu ntawm lub pob zeb thiab lwm yam khoom; reclamation ua solonetzes; sanding, loosening, Plantage, earthing, glinovanie thiab thawj tillage; raws li zoo li lwm yam hauj lwm.

Hom tshuaj reclamation yog: gypsum, phosphorites, Liming.

Qhov tseem tangible tshwm sim ntawm reclamation muab rau complex daim ntawv thov ntawm tag nrho los yog ib co ntawm nws hom. Tsis tas li ntawd, nws cov hauj lwm zoo nyob ntawm txoj kev siv thiab kulturtehnicheskih tej hauj lwm. Complex av reclamation ua hauj lwm mus rau ib tug tej yam cheeb tsam yuav yog nyob ntawm seb nws ua liaj ua teb siv (technology ntawm cultivation, qoob loo tig, xaiv ntawm ntau yam thiab cov qoob loo) thiab hom ntawm kev loj hlob.

Rau qhov zoo tshaj plaws qhia aav drained av noo yog ensured los ntawm nws ob sab sib dho kev cai. Yuav kom txhim tsa no kua-moistening systems uas muab dehumidification nrog irrigation, cov qauv ntawm cov dewatering thaum lub sij hawm hnyav dej nag thiab dej thiab lub caij nplooj ntoos hlav nyob rau hauv lub qhuav rau lub caij. Ib txhij nrog xws li tshuab rau hauv lub irrigated chaw, tsim kua network, uas tsis pub ib tug muaj zog rov qab ntawm av thiab tswj ntawm saline xau. Acidic xau yog raug rau Liming.

Av reclamation kev nyab xeeb leads mus rau ib txoj kev txhim kho, tshwj xeeb tshaj yog nyob rau hauv arid thaj chaw, raws li nyob rau hauv reflux nyob rau hauv tus nto txheej tsub kom cov av noo (vim lub evaporating ntawm cov nroj tsuag thiab cov av noo noo). Qhov no nyob rau hauv lem ua rau ib tug nco nyob rau hauv kub thiab softens tej yam uas lub caij ntuj.

Feem ntau reclamation siv mus rau pua pua txhiab tus hectares av. Qhov no feature yuav txais qhov tseem ceeb ntawm cov kev xaiv ntawm lub system ntawm reclamation ua hauj lwm rau ib tug scientific hauv paus, uas tsis entail ib tug tsis zoo feem nyob rau ib puag ncig thiab nws cov kev pab. Yuav kom tsim ib qhov project ntawm av reclamation ua hauj lwm nyob rau hauv lub teb chaws, ua ntej ua txoj geological, topographic, geodesic, hydrological, climatological, geo-botanical, av, thiab lwm yam kev tshawb fawb.
