Indawo yokusetyenziswa kwevalve yentsimbi etyhidiweyo inokwahlulwa ibe yimiba ye-8: Umbhobho wokubonelela ngamanzi amdaka, umbhobho wokubonelela ngamanzi wokwakha, umbhobho wokuhambisa amanzi, umbhobho wokuhambisa amanzi ogqwethiweyo, umbhobho wokuhambisa igesi, umbhobho wombane, umbhobho wezolimo, umbhobho woshishino njalo njalo.Uphuhliso lwesakhiwo sobonelelo lwamanzi kunye nombhobho wokukhupha amanzi ngowona ukhawulezayo, uphuhliso lonikezelo lwamanzi okwakha kunye nombhobho wokuhambisa amanzi lungcono, kwaye uphuhliso lombhobho wokuhambisa amanzi angaphantsi komhlaba kunye nombhobho wokuhambisa igesi usemva kakhulu kumazwe angaphandle.

Nangona kunjalo, ukuphuhliswa kweevalve zentsimbi kunye nezinye izinto zombhobho e-China zibuyele ngasemva.Ngokutsho kwenkcazo yeengcali ezihambelanayo, umlinganiselo ofanelekileyo wombhobho kunye nokulungelelaniswa kolwakhiwo kufuneka ube ngu-8: 1, kodwa ngokweenkcukacha manani ngo-1998, umthamo wemveliso yombhobho wentsimbi kunye nokulungelelaniswa kokwakhiwa eChina malunga ne-20: 1 .Umthamo wemveliso yokufakelwa kwemibhobho yentsimbi iye yehla kancinci kwiminyaka yakutshanje, kodwa isengalingani.Uninzi lwabavelisi bokufakelwa kwemibhobho yentsimbi ngamashishini amancinci kwaye ambalwa amashishini amakhulu okanye aphakathi.

Kushishino lwesikhululo seenqwelomoya zobuNjineli, umsantsa phakathi kwasekhaya nelangaphandle ubonakaliswa ikakhulu kumgangatho wobugcisa wamacandelo asisiseko.Ngoko ke, ukuvuselela uphuhliso loshishino loomatshini bokwakha, kufuneka sisekele iinzame zethu ekuphuculeni umgangatho wobugcisa wamacandelo asisiseko, ukwandisa inqanaba lezinto ezintsha zobuchwepheshe, kunye nokuncedisa ngenkxaso yomgaqo-nkqubo, ukuze siphucule ngokusisiseko umgangatho wobugcisa. Ukuqonda uphuhliso lweshishini.

Imfuno yemarike yeemveliso zevalvu yentsimbi etyhidiweyo ikakhulu ivela kwimiba emibini: eyokuqala, ukusetyenziswa ngombhobho wentsimbi;okwesibini, ukusetyenziswa kwevalve yentsimbi, ukuqina, ukuxhathisa ukukhathala, ukuxhathisa i-corrosion ayifanelekanga kakhulu, kodwa inomgangatho wokukhanya, ukusebenza kakuhle kokusebenza kunye nezinye iingenelo ezizodwa.Kwilizwe langaphandle, iivalvu zentsimbi zisetyenziswe ngokubanzi kwishishini lemichiza, iyeza, ukutya, ukubonelelwa kwamanzi angaphakathi nangaphandle kunye ne-drainage, iimveliso zoomatshini kunye nombane, ezolimo kunye nezinye iindawo.Kunokulindelwa ukuba iimveliso zevalve yentsimbi ephosiweyo ezinomgangatho ophezulu, ukusebenza kunye nexabiso zinamandla amakhulu emarike eTshayina.Nasemva kokungena kweTshayina kwi-WTO, zikwazimveliso ezilungileyo zokukhuphisana kwimarike yamazwe ngamazwe.

Ukuphendula kwiimfuno ezahlukeneyo zabathengi, uphuhliso lwezisombululo ezibanzi zokubonelela lula kubathengi, kodwa kwakhona wadlala ukudityaniswa okuthe tye kwenzuzo yesikali, ukuze iintlobo ngeentlobo zeemveliso zokwabelana nge-asethi engabonakaliyo, ukwandisa ukubonakala kwamashishini, umyalelo wokwenza imiqobo kubangeneli abatsha kwishishini, ukunciphisa uxinzelelo lokhuphiswano, kunye nokufumana indawo enkulu yenzuzo;ngoyantlukwano, ngakumbi ukudityaniswa okuthe tye kunye nokuthe nkqo kunye nokufunyanwa, kunokunciphisa abo bakhuphisana nabo, ukwandisa isabelo semarike, ukuphucula ukuxhamla kwimarike, ukwenza ishishini lifumane i-synergy effect.

Ukuze kukhuthazwe inkxaso yesizathu sokukhuselwa kwendalo, ukuqinisekisa imfuneko yenkxaso-mali yokukhusela indalo, amazwe athatha indlela eyahlukileyo yokuchaphazeleka ngokukhawuleza.Ngokomzekelo, iYurophu ifumana inkxaso-mali kwi-World Wildlife Fund yoPhando kunye nophuhliso lwezinye iindlela ze-tetrachloroethene, kwaye amanye amazwe ahlawulisa irhafu ekhethekileyo yokusingqongileyo kwiintengiso ze-tetrachloroethene, ezisetyenziselwa ukuphatha inkunkuma ye-tetrachloroethene.
