Eutrophication (los ntawm Greek eutrophos, "zoo-nourished"), los yog hypertrophication, yog thaum lub cev ntawm cov dej ua overly enriched nrog cov zaub mov thiab cov as-ham uas induce ntau loj hlob ntawm algae. Cov txheej txheem no tuaj yeem ua rau oxygen depletion ntawm lub cev dej.

Yog li ntawd, eutrophication yog dab tsi hauv cov lus yooj yim?

Kev txhais ntawm eutrophification .: Cov txheej txheem los ntawm lub cev ntawm cov dej tau ua kom muaj cov khoom noj muaj kuab lom (xws li phosphates) uas txhawb kev loj hlob ntawm cov nroj tsuag hauv dej feem ntau ua rau cov pa oxygen depletion.

Tsis tas li ntawd, puas yog eutrophication zoo lossis phem? Nyob rau hauv me me lawv muaj txiaj ntsig zoo rau ntau lub ecosystems. Txawm li cas los xij, nyob rau hauv ntau ntau, cov as-ham ua rau ib hom pa phem hu ua eutrophification . Eutrophication stimulates kev loj hlob tawg ntawm algae (algal blooms) uas depletes cov dej ntawm oxygen thaum cov algae tuag thiab noj los ntawm cov kab mob.

Tsis tas li ntawd, dab tsi yog qhov ua rau eutrophication?

Eutrophication Feem ntau yog tshwm sim los ntawm tib neeg kev ua ub no uas ua rau ntau tshaj ntawm nitrogen thiab phosphorus rau hauv dej. Agricultural chiv yog ib qho ntawm cov tib neeg tseem ceeb ua rau eutrophication . Kev siv, lossis siv ntau dhau, ntawm cov chiv tuaj yeem ua cov as-ham no kom ntws tawm ntawm cov neeg ua liaj ua teb thiab nkag mus rau hauv dej.

Yuav ua li cas kom tshem tau ntawm eutrophication?

Tswj

  1. txhim kho kev ua kom huv ntawm cov dej khib nyiab kho cov nroj tsuag, txhim kho tertiary kho tshuab kom txo cov khoom noj muaj txiaj ntsig;
  2. kev siv cov lim dej kom zoo kom tshem tawm cov nitrogen thiab phosphorus tam sim no hauv cov dej ntws tawm (xws li cov nroj tsuag phyto-purification);
