I-oxygen yama-molecule encibilikisiwe emanzini ibizwa ngokuthi i-oxygen encibilikisiwe futhi ivame ukubizwa ngokuthi i-D0. Inani le-oxygen encibilikisiwe emanzini angaphezulu lingu-5-10mg/L. Uma kunemimoya enamandla namagagasi, i-oxygen encibilikisiwe emanzini ingafinyelela ku-14mg/L. Ukugcwala kwe-oxygen encibilikisiwe = inani elilinganisiwe le-oxygen encibilikisiwe/ukugcwala kwe-oxygen encibilikisiwe ngaphansi kwezimo ezilinganisiwe * 100%, okungukuthi, 90% nangaphezulu, inani elilinganisiwe lingaphezu kuka-7.5 mg/L, kanti ubuncane bungu-2 mg/L.
I-oxygen ephansiamanziizodlula ezitshalweni futhi isuse umoya-mpilo ezimpandeni. Ngokufanayo, izoqeda umoya-mpilo enhlabathini. Izitshalo ezinempilo kanye nezitshalo zomhlabathi ezinempilo zidinga umoya-mpilo kulezi zingxenye ezimbili.
Ukuntuleka komoya-mpilo oncibilikisiwe emanzini nakho kungabangela ezinye izinkinga. Isibonelo, ama-nematode athanda inhlabathi engenawo umoya-mpilo. Ukunisela izitshalo ngamanzi angenayo umoya-mpilo kuzozisondeza ebusweni futhi kulimaze kalula izimpande zezitshalo.
Izifundo zikhombisile ukuthi ukunciphisa ukugcwala komoya-mpilo oncibilikisiwe endaweni yezimpande zezitshalo kuzonciphisa ikhono lezitshalo lokumunca i-nitrogen namanzi. Ukuntuleka komoya-mpilo kungalimaza izimpande. Enkambisweni yokuzivumelanisa nokugxila okuphansi komoya-mpilo oncibilikisiwe, indlela yokugaya ukudla kwezitshalo ishintshile. I-Hypoxia ngaphakathi kwesitshalo ibizwa ngokuthi i-hypoxia yangaphakathi. Omunye wemiphumela ukuwohloka kwe-sucrose, futhi izitshalo ziphendukela ezindleleni zokonga amandla ukuze zibuyisele ukuntuleka komoya-mpilo.
I-photosynthesis ye-phytoplankton ingumthombo oyinhloko we-oxygen emachibini, ngokuvamile ibangela u-56%-80% womthombo we-oxygen; okunye kuvela ekuvunguzeni komoya kanye namagagasi, ukuze i-oxygen esemoyeni incibilike ngqo emanzini.amanzi. Inenzuzo engu-12-14mg/L
I-Heilongjiang: A 600-square-imithaichibi lokushiswa kwesikhumba lingakhuphula izinga lokushisa kwamanzi ngama-degrees angu-3 kuya kwangu-4 futhi likhuphule ukukhiqizwa kokusanhlamvu ngo-6%.
