Eutrophication yezvitumbi zvemvura zvinoreva chiitiko chekuti pasi pesimba remabasa evanhu, chikafu chakadai senitrogen nephosphorus chinodiwa nezvisikwa chinopinda mumvura inoyerera inononoka yakaita semadziva, nzizi, bays, nezvimwewo muhuwandu hwakawanda, zvichikonzera kuberekana nekukurumidza. algae nemamwe plankton, kuderera kweokisijeni yakanyungudika mumvura yemvura, kuderera kwemvura, uye kufa kwehove nezvimwe zvipenyu.
Zvikonzero zvaro zvinonyanya kusanganisira zvinotevera zvinhu:
1. Kuwedzeredza kudya: Kuwanda kwehuwandu hwehupfu hwakadai se phosphorus yakazara uye yakazara nitrogen ndiyo yakananga chikonzero che eutrophication yemitumbi yemvura.
2. Mamiriro ekuyerera kwemvura: Mamiriro ekuyerera kwemvura inononoka (yakadai semadziva, madhamu, nezvimwewo) inoita kuti zviome kuti zvinovaka muviri zviri mumuviri wemvura zvicheneswe uye zviparadzirwe, izvo zvinobatsira pakukura kwealgae.
3. Kupisa kwakakodzera: Kuwedzera kwekushisa kwemvura, kunyanya pakati pe20 ℃ kusvika ku35 ℃, kuchasimudzira kukura uye kubereka kwealgae.
4. Zvinhu zvevanhu: Kuwanda kwenitrogen uye phosphorus-ine tsvina yemvura, marara uye mafetiraiza anobudiswa neindasitiri, zvekurima uye hupenyu munzvimbo dzakapoteredza dzakabudirira mune zvehupfumi uye dzine vanhu vakawanda zvikonzero zvakakosha zvevanhu zve eutrophication yemitumbi yemvura. .
Eutrophication yemitumbi yemvura uye kukanganisa kwezvakatipoteredza
Kukanganisa kwe eutrophication yemitumbi yemvura pane zvakatipoteredza inonyanya kuratidzwa mune zvinotevera zvinhu:
1. Kushatisa kwehutano hwemvura: Kuberekana kukuru kwealgae kuchapedza oxygen yakanyungudika mumvura yemvura, zvichikonzera kuderera kwehutano hwemvura uye kukanganisa kurarama kwezvisikwa zvemvura.
2. Kusaenzana kwezvipenyu: Kukura kunopenga kwealgae kuchaparadza zvinhu uye kuyerera kwesimba remumvura, zvichitungamira kusaenzana mukugovaniswa kwemarudzi, uye kunyange zvishoma nezvishoma kuparadza iyo yese yemvura ecosystem. .
3. Kusvibiswa kwemhepo: Kuora uye kuparara kwealgae kuchabudisa kunhuwa uye kusvibisa mamiriro ekunze.
4. Kushaikwa kwemvura: Kushata kwemvura kuchawedzera kushomeka kwezviwanikwa zvemvura.
Dziva rakanga rakachena uye risina magumo rakaerekana rasvibira. Izvi zvingasava simba remuchirimo, asi chiratidzo chenyevero ye eutrophication yemitumbi yemvura.
Eutrophication yehutano hwemvura, mumashoko akajeka, "kuwedzeredza" mumitumbi yemvura. Kana zvinhu zvinovaka muviri zvakaita senitrogen nephosphorus mumvura inoyerera zvishoma nezvishoma zvakaita semadziva nenzizi zvanyanya, zvinoita sekuvhura “buffet” yealgae nemamwe plankton. Vachabereka zvikara uye voita "maruva emvura". Izvi hazviiti chete kuti mvura iite mhirizhonga, asiwo inounza nhevedzano yezvinetso zvakakomba zvezvakatipoteredza.
Simba rinokurudzira eutrophication yemitumbi yemvura, saka izvi zvinovaka muviri zvakawandisa zvinobva kupi? Pane kunyanya zvinotevera zvinyorwa:
Fetereza yezvekurima: Kuti zvirimwa zviwedzere goho, fetiraiza yakawanda yemakemikari inoshandiswa, uye manyowa enitrogen nephosphorus akawanda anoyerera achipinda mumvura pasi pemvura inonaya.
Tsvina yemumba: Tsvina yemudzimba mumaguta ine huwandu hukuru hwezvinovaka mumidziyo yekugezesa nezvinosara zvekudya. Kana iyo ikaburitswa yakananga pasina kurapwa kana kubatwa zvisina kunaka, inova iyo honzeri ye eutrophication yemitumbi yemvura.
Kuburitswa kwemaindasitiri: Mamwe mafekitori anoburitsa tsvina ine nitrogen uye phosphorus panguva yekugadzira. Kana ikasabudiswa zvakanaka, inosvibisawo muviri wemvura.
Zvinhu zvakasikwa: Kunyange zvazvo zvinhu zvakasikwa zvakadai sekukukurwa kwevhu zvinogonawo kuunza humwe hutano, munharaunda yemazuva ano, mabasa evanhu ndiwo anokonzera eutrophication yehutano hwemvura.
Migumisiro ye eutrophication yemitumbi yemvura:
Kushatisa kwemhando yemvura: Kuberekana kukuru kwealgae kunopedza okisijeni yakanyungudika mumvura, zvichiita kuti mvura ishaye simba uye kunyange kuburitsa kunhuhwirira kusingafadzi.
Ecological kusaenzana: Kuputika kwealgae kunosvina nzvimbo yekugara yezvimwe zvipenyu zvemumvura, zvichikonzera kufa kwehove nezvimwe zvipenyu uye kuparadza kuenzana kwezvisikwa.
Kurasikirwa kwehupfumi: Eutrophication ichakanganisa kusimukira kwemaindasitiri akaita sehove nekushanya, zvichikonzera kurasikirwa kuhupfumi hwenzvimbo.
Ngozi dzeutano: Mitumbi yemvura yeEutrophic inogona kunge iine zvinhu zvinokuvadza, senge mabhakitiriya uye chepfu, izvo zvinokanganisa hutano hwevanhu.
Yakasanganiswa nezvinokonzeresa eutrophication yemitumbi yemvura, inodiwa nitrogen uye phosphorus index bvunzo dzinoitwa pamusha wetsvina uye tsvina yemumaindasitiri, uye "kuvharira" kubva kune sosi kunogona kunyatso kudzikisa kupinza kweiyo exogenous chikafu. Panguva imwecheteyo, kucherechedzwa nekutariswa kwenitrogen, phosphorus uye zvimwe zviratidzo mumadziva nenzizi zvinopa rubatsiro rwakakosha rwe data uye sarudzo dzekuita sarudzo dzekuchengetedza uye kuchengetedzwa kwemhando yemvura.
Ndezvipi zviratidzo zvinoedzwa eutrophication yemitumbi yemvura?
Zviratidzo zvekuonekwa kwemvura eutrophication zvinosanganisira chlorophyll a, yakazara phosphorus (TP), yakazara nitrogen (TN), pachena (SD), permanganate index (CODMn), yakanyungudutswa okisijeni (DO), biochemical oxygen kudiwa (BOD), makemikari okisijeni kudiwa ( COD), yakazara organic kabhoni (TOC), yakazara oxygen kudiwa (TOD), nitrogen yemukati, phosphorus yemukati, yakazara mabhakitiriya, nezvimwe.
LH-P300 inotakurika yakawanda-parameter yemhando yemvura mita inogona kukurumidza uye nemazvo kuyera.COD, ammonia nitrogen, phosphorus yakazara, nitrogen yakazara, organic pollutants uye inorganic pollutants mumasampuli emvura. Inogona kusangana nezvinodiwa zvekuonekwa zvekiyi nitrogen uye phosphorus zviratidzo zvemvura eutrophication. Iyo chiridzwa idiki uye yakareruka, iri nyore kushandisa uye inoshanda zvizere, ine yakanyanya kudhura kuita. Mvura eutrophication ine hukama nehupenyu hwemunhu wese, hutano uye hupenyu hwehupenyu. Kuburikidza nekuongorora kwesainzi uye mhinduro, ndinotenda kuti tichakwanisa kukunda dambudziko iri uye kuchengetedza zviwanikwa zvemvura izvo zvatinovimba nazvo kuti tirarame. Ngatitangei kubva zvino, titange kubva pazvinhu zvidiki zvakatikomberedza, uye tibatsire mukusimudzirwa kwakasimba kwezviwanikwa zvemvura!
