Ka lilemo tse 25, Lefapha la Tikoloho la Malaysia (DOE) le sebelisitse Index ea Boleng ba Metsi (WQI) e sebelisang litekanyetso tse tšeletseng tsa boleng ba metsi: oksijene e qhibilihisitsoeng (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), pH, ammonia nitrogen (AN) le solids suspended (SS). Tshekatsheko ya boleng jwa metsi ke karolo e e botlhokwa ya taolo ya metswedi ya metsi mme e tshwanetse go laolwa ka tshwanelo go thibela tshenyo ya tikologo mo kgotlelong le go netefatsa kobamelo ya melawana ya tikologo. Sena se eketsa tlhoko ea ho hlalosa mekhoa e sebetsang ea tlhahlobo. E 'ngoe ea liqholotso tse kholo tsa komporo ea hajoale ke hore e hloka letoto la lipalo tsa subindex tse jang nako, tse rarahaneng le tse nang le liphoso. Ho feta moo, WQI e ke ke ea baloa haeba parameter e le 'ngoe kapa tse ngata tsa boleng ba metsi li le sieo. Thutong ena, mokhoa oa ho ntlafatsa oa WQI o hlahisoa bakeng sa ho rarahana ha ts'ebetso ea hajoale. Bokhoni ba ho etsa mohlala o tsamaisoang ke data, e leng Nu-Radial basis function support vector machine (SVM) e ipapisitseng le 10x cross-validation, e ile ea ntlafatsoa le ho hlahlojoa ho ntlafatsa bolepi ba WQI sebakeng sa Langat. Ho ile ha etsoa tlhahlobo e felletseng ea kutloelo-bohloko tlas'a maemo a ts'eletseng ho fumana bokhoni ba mohlala boprofeteng ba WQI. Boemong ba pele, mohlala oa SVM-WQI o bontšitse bokhoni bo botle ba ho etsa DOE-WQI mme o fumane maemo a holimo haholo a lipalo-palo (correlation coefficient r> 0.95, Nash Sutcliffe performance, NSE>0.88, Willmott's consistency index, WI> 0.96). Boemong ba bobeli, mokhoa oa ho etsa mohlala o bontša hore WQI e ka hakanngoa ntle le li-parameter tse tšeletseng. Kahoo, paramente ea DO ke eona ntho ea bohlokoahali ho khethollang WQI. pH e na le phello e fokolang ho WQI. Ho phaella moo, Scenarios 3 ho ea ho 6 e bonts'a katleho ea mohlala ho latela nako le litšenyehelo ka ho fokotsa palo ea mefuta-futa ea motsoako oa ho kenya mohlala (r> 0.6, NSE> 0.5 (e ntle), WI> 0.7 (e ntle haholo)). Ha u kopane, mohlala o tla ntlafatsa haholo le ho potlakisa ho etsa liqeto tse tsamaisoang ke data tsamaisong ea boleng ba metsi, ho etsa hore data e fumanehe haholoanyane le ho kopanela ntle le ho kenella ha batho.

Poleloana “tšilafalo ea metsi” e bolela tšilafalo ea mefuta e ’maloa ea metsi, ho akarelletsa le metsi a holim’a metsi (maoatle, matša le linōka) le metsi a ka tlas’a lefatše. Lebaka le ka sehloohong le etsang hore bothata bona bo hōle ke hore lintho tse silafatsang ha li tšoaroe ka ho lekaneng pele li ntšoa ka ho toba kapa ka tsela e sa tobang metsing. Liphetoho tsa boleng ba metsi li na le tšusumetso e kholo eseng feela tikolohong ea Marine, empa hape le ho fumaneha ha metsi a hloekileng bakeng sa phepelo ea metsi a sechaba le temo. Linaheng tse tsoelang pele, khōlo e potlakileng ea moruo e tloaelehile, ’me morero o mong le o mong o khothalletsang khōlo ena e ka ba kotsi tikolohong. Bakeng sa taolo ea nako e telele ea mehloli ea metsi le ts'ireletso ea batho le tikoloho, ho lekola le ho lekola boleng ba metsi ho bohlokoa. Index ea Boleng ba Metsi, e tsejoang hape e le WQI, e nkiloe ho data ea boleng ba metsi 'me e sebelisetsoa ho fumana boemo ba hajoale ba boleng ba metsi a linōka. Ha ho hlahlojoa tekanyo ea phetoho ea boleng ba metsi, mefuta e mengata e tlameha ho nkoa. WQI ke index e se nang tekanyo. E na le liparamente tse khethehileng tsa boleng ba metsi. WQI e fana ka mokhoa oa ho khetholla boleng ba libaka tsa metsi tsa khale le tsa hona joale. Boleng bo utloahalang ba WQI bo ka susumetsa liqeto le liketso tsa baetsi ba liqeto. Ka tekanyo ea 1 ho isa ho 100, ha index e phahame, boleng ba metsi bo betere. Ka kakaretso, boleng ba metsi a liteishene tsa linōka tse nang le lintlha tse 80 ho ea holimo li finyella litekanyetso tsa linōka tse hloekileng. Boleng ba WQI bo ka tlase ho 40 bo nkoa bo silafetse, ha boleng ba WQI bo pakeng tsa 40 le 80 bo bontša hore boleng ba metsi bo silafetse hanyane.
Ka kakaretso, ho bala WQI ho hloka sete ea liphetoho tsa subindex tse telele, tse rarahaneng, le tse nang le liphoso. Ho na le litšebelisano tse rarahaneng tse se nang moeli lipakeng tsa WQI le likarolo tse ling tsa boleng ba metsi. Ho bala li-WQI ho ka ba thata 'me ho nka nako e telele hobane li-WQI tse fapaneng li sebelisa liforomo tse fapaneng, tse ka bakang liphoso. Phephetso e 'ngoe e kholo ke hore ha ho khonehe ho bala foromo ea WQI haeba e le 'ngoe kapa tse ngata tsa boleng ba metsi li le sieo. Ntle le moo, litekanyetso tse ling li hloka mekhoa e nkang nako, e felletseng ea pokello ea sampole e tlamehang ho etsoa ke litsebi tse koetlisitsoeng ho netefatsa tlhahlobo e nepahetseng ea lisampole le pontšo ea liphetho. Ho sa tsotellehe ntlafatso ea theknoloji le lisebelisoa, tlhokomelo e pharaletseng ea nako le sebaka sa metsi a linōka e sitisitsoe ke litšenyehelo tse phahameng tsa ts'ebetso le tsamaiso.
Puisano ena e bontša hore ha ho na mokhoa oa lefats'e oa WQI. Sena se phahamisa tlhoko ea ho theha mekhoa e meng ea ho bala WQI ka mokhoa o sebetsang hantle le o nepahetseng. Lintlafatso tse joalo li ka ba molemo ho batsamaisi ba mehloli ea tikoloho ho beha leihlo le ho lekola boleng ba metsi a linōka. Tabeng ena, bafuputsi ba bang ba atlehile ho sebelisa AI ho bolela esale pele WQI; Mokhoa oa ho ithuta mochini o thehiloeng ho Ai o qoba lipalo tsa index e nyane mme o hlahisa liphetho tsa WQI kapele. Li-algorithms tsa ho ithuta ka mochini oa Ai li ntse li tsebahala ka lebaka la meralo ea tsona e se nang moeli, bokhoni ba ho bolela liketsahalo tse rarahaneng, bokhoni ba ho laola lisebelisoa tse kholo tsa data ho kenyelletsa le data ea boholo bo fapaneng, le ho hloka kutlo ho data e sa fellang. Matla a bona a ho bolela esale pele a itšetlehile ka ho feletseng ka mokhoa le ho nepahala ha pokello ea data le ts'ebetso.
