Qhov sib txawv tseem ceeb ntawm eutrophication thiab kev vam meej yog tias eutrophcation tshwm sim hauv lub cev dej hos qhov kev vam meej tshwm sim hauv txhua qhov chaw.

Eutrophication thiab succession yog maj mam hloov uas tshwm sim nyob rau hauv ib puag ncig. Lawv yog cov txheej txheem tseem ceeb tshwm sim los ntawm ob qho tib si natural thiab unnatural tshuaj los yog tshwm sim uas tsis tuaj yeem nres los ntawm cov txiv neej thaum nws tau tshwm sim. Eutrophication ua rau muaj kuab paug hauv dej li no, cuam tshuam rau cov tsiaj hauv dej thiab cov tsiaj. Thaum lub eutrophication tshwm sim, nws txo lub teeb nkag mus, thiab tseem ua rau kom cov pa oxygen xav tau thiab txo cov pa oxygen. Ntawm qhov tod tes, kev vam meej ua rau muaj lub zej zog dhau lub sijhawm.

Eutrophication yog dab tsi?

Lo lus eutrophication yog los ntawm Greek lo lus, eutrophia thiab lo lus German Eutrophie, uas txhais tau tias muaj zaub mov txaus, kev loj hlob, thiab noj qab nyob zoo. Eutrophication tshwm sim los ntawm kev sib sau ntawm cov khoom ntuj lossis cov khoom siv dag zog, xws li phosphates thiab nitrates, los ntawm cov dej phwj tuaj lossis cov chiv, hauv cov dej hauv dej. Yog li, qhov no yog qhov xwm txheej uas muaj qhov nce lossis tawg ntawm phytoplankton hauv lub cev dej. Vim li no, cov dej tshwm hauv cov xim ntsuab hauv lub cev dej eutrophic.

Daim duab 01: Eutrophication

Ntawm no, txij li cov algae loj hlob ntau dhau, nws thaiv kev nkag mus ntawm tshav ntuj mus rau hauv qab ntawm lub cev dej. Thiab vim li no, qhov no ua rau kev tuag ntawm cov nroj tsuag sib txawv nrog rau algae vim lub hnub ci tsis txaus rau photosynthesis. Thaum kawg, microorganisms ua rau cov organic teeb meem tuag hauv lub cev dej thiab yog li, cov pa oxygen xav tau nce ntxiv. Tsis tas li ntawd, thaum lub sij hawm microbial decomposition, cov khoom siv tshuaj lom sib txawv xws li gasses tso rau hauv ib puag ncig. Vim li no, cov pas dej eutrophic tso cov ntxhiab tsw phem ua rau ib puag ncig muaj kuab lom. Tsis tas li ntawd, lwm yam kev cuam tshuam tsis zoo suav nrog kev txo qis ntawm cov pa oxygen tam sim no hauv dej thiab txo cov tsiaj txhu xws li cov ntses tshwj xeeb.

Kev vam meej yog dab tsi?

Kev vam meej yog hais txog qhov tsawg dua lossis ntau dua thiab ua kom muaj kev hloov pauv hauv cov qauv lossis kev teeb tsa ntawm cov zej zog ecological. Thiab, qhov no feem ntau tshwm sim los ntawm kev tsim ib thaj chaw tshiab, tsis muaj chaw nyob (piv txwv: av qeeg loj lossis lava ntws) lossis los ntawm qee yam cuam tshuam (kev txiav, cua pov, lossis hluav taws).

Daim duab 02: Kev vam meej

Dhau li ntawd, kev vam meej muaj ob hom; lawv yog thawj succession thiab theem nrab succession. Nyob rau hauv thawj succession, ib qho chaw nyob colonizes thawj zaug thaum nyob rau hauv theem nrab succession, ib tug yav tas los nyob hauv vaj tse colonizes dua tom qab muaj kev cuam tshuam los yog puas. Tsis tas li ntawd, nyob rau hauv thawj succession, ceev-loj hlob thiab zoo-tswj hom yuav dominate thaum nyob rau hauv lub thib ob succession, ntau sib tw hom yuav dominate. Ua li no, kev vam meej yuav vam meej los ntawm lub zej zog uas muaj ntau hom tsiaj qis mus rau ib lub zej zog uas muaj ntau hom ntau haiv neeg.

Dab tsi yog qhov zoo sib xws ntawm Eutrophication thiab Succession?

  • Eutrophication thiab succession yog ob txheej txheem tshwm sim nyob rau hauv ib puag ncig.
  • Ob leeg tuaj yeem ua tau zoo thiab qhov tsis zoo.

Qhov txawv ntawm Eutrophication thiab Succession yog dab tsi?

Eutrophication yog cov txheej txheem ntawm kev loj hlob algal ntau dhau hauv lub cev dej vim muaj cov khoom noj xws li phosphates thiab nitrates. Ntawm qhov tod tes, kev ua tiav yog txheej txheem ntuj tsim uas hais txog kev hloov pauv ntawm cov tsiaj hauv ib lub zej zog. Qhov sib txawv tseem ceeb ntawm eutrophication thiab succession yog tias eutrophication tshwm sim hauv lub cev dej thaum qhov kev vam meej tshwm sim hauv txhua qhov chaw.

Ntxiv mus, eutrophication tuaj yeem tshwm sim vim yog vim li cas ntuj tsim xws li kev tawm ntawm cov khoom noj los ntawm cov av thiab huab cua ntawm pob zeb los yog vim yog cov khoom tsim los yog tsim los ntawm tib neeg xws li tso cov tshuaj detergents uas muaj phosphates. Whereas, rau succession, cov ua yog feem ntau natural tshwm sim xws li yaig, kev puas tsuaj loj, thiab lwm yam. Li no, qhov ua rau tshwm sim kuj yog ib qho txawv ntawm eutrophication thiab succession. Tsis tas li ntawd, ib qho kev sib txawv ntawm eutrophication thiab succession yog qhov tshwm sim. Qhov ntawd yog; eutrophication tuaj yeem ua rau tuag thiab tsis muaj zaub mov hauv qee cov tsiaj. Tab sis, kev vam meej tsim ib thaj chaw tshiab thiab tseem, cov kev hloov pauv tau pom tseeb heev. Tsis tas li ntawd, thaum eutrophication phem zuj zus tuaj, nws tuaj yeem txo qhov muaj nyob ntawm qee hom thaum kev vam meej tuaj yeem muab lwm cov tsiaj nyob hauv thaj chaw qub. Tsis tas li ntawd, eutrophication tshwm sim maj mam thiab qee zaum; nws lig dhau rau tus txiv neej ua ib yam dab tsi txog nws.

Summary – Eutrophication vs Succession

Nyob rau hauv cov ntsiab lus ntawm qhov sib txawv ntawm eutrophication thiab succession; eutrophication thiab succession yog maj mam hloov uas yuav tshwm sim nyob rau hauv ib puag ncig. Txawm li cas los xij, eutrophication ua rau algal blooms vim kev nplua nuj ntawm cov dej hauv lub cev los ntawm nitrates thiab phosphates hauv ntau qhov ntau. Thiab, qhov ntawd cuam tshuam rau qib sib txawv hauv lub cev dej. Nws yog ib hom pa phem uas ua rau muaj kev puas tsuaj rau ib puag ncig. Ntawm qhov tod tes, kev vam meej yog hais txog ntau dua los yog tsawg dua qhov kev hloov pauv hauv cov qauv lossis kev teeb tsa ntawm cov zej zog ecological. Nws yog cov txheej txheem ntuj tsim thiab tsis yog hom kev ua qias tuaj. Li no, nws tsis ua rau muaj kev cuam tshuam rau ib puag ncig.
