Njengoko sisazi sonke, ukucocwa kogutyulo lwelindle emaphandleni kufuneka kudityaniswe nemeko yokwenyani yokuhlaliswa kwabantu emaphandleni ukuze kuthathwe indlela yasekuhlaleni, kwangaxeshanye kuqwalaselwe umjikelo osebenzayo wokusetyenziswa kobutyebi kunye nolawulo longcoliseko. Ukusetyenziswa kwemithombo yasemaphandleni yasemaphandleni emva kokunyanga okuphakathi kunokunciphisa utyalo-mali lokucocwa kwamanzi amdaka, ukuphinda kusetyenziswe izibonelelo zamanzi ezolimo kunye nenitrogen kunye ne-phosphorus, kwaye kusetyenziswe ngokupheleleyo izibonelelo zomhlaba wasemaphandleni kunye nomthamo wokucocwa kokusingqongileyo kwamanzi. Ngenxa yemfuno engxamisekileyo yokuphucula imeko yasemaphandleni, ukusetyenziswa ngokufanelekileyo kwamanzi amdaka asemaphandleni kuya kuba yinjongo yexesha elide yophuhliso oluzinzileyo lokucocwa kogutyulo.
Umsebenzi woncedo kufuneka ususwe ngokukhawuleza ukucinga okukhoyo
Okwangoku, unyango lwamanzi amdaka asemaphandleni aseChina, ngokukodwa kusetyenziswa izixhobo ezidibeneyo + iindlela ze-ecological, kodwa ukusebenza kwezibonelelo akukho nethemba. Ezinye iindawo zokucoca ziziziko zogutyulo lwelindle ezidolophini 'miniaturisation', iindleko zokwakha, ukusebenza kunye nokugcinwa kwazo ziphezulu, imimandla yasemaphandleni kunzima ukuyamkela, kodwa kwakhona akuhoywanga ukusetyenziswa kwemithombo yelindle yasekhaya ukugcina indima yokuchuma komhlaba. Ngenxa yenqanaba elilinganiselweyo loqoqosho lwasemaphandleni kunye nobuchwepheshe, inani elikhulu lemisebenzi yokucocwa kwamanzi amdaka, ukwenzela ukuba iindawo ezininzi zeendawo zonyango, uthungelwano lwemibhobho alukwazi ukwakha, alukwazi ukuhlawula, ukunqongophala kwabasebenzi abaqeqeshiweyo kunye nobugcisa bokulawula. Kwimeko yangoku yokufudukela kwabantu ezidolophini ngokukhawuleza, ukucocwa kwamanzi amdaka emaphandleni kufuneka kucuthwe iindleko ezinzulu ezifana neziseko ezingundoqo kunye nothungelwano lwemibhobho, ukususa ukucinga okungokwemvelo, nokukhuthaza imifuziselo eneendleko eziphantsi, ekulula ukuyigcina yonyango oluphakathi kunye nokusetyenziswa kobutyebi.
Ukusetyenziswa kwezibonelelo kugxininiswa kwimigangatho yokukhutshwa
Ngokwemigangatho yokukhutshwa kwamanzi ephunyeziweyo kunyango lwamanzi amdaka asemaphandleni, kwiminyaka yakutshanje, unyango oluphakathi kunye nokusetyenziswa kobutyebi kuye kwagxininiswa ngokuthe ngcembe kwimigangatho yokukhutshwa kwamanzi. Ngokwezibalo, esona siseko sixhaphakileyo sokuphunyezwa kwemigangatho yezibonelelo zonyango yi-GB18918-2002, kodwa ngo-2019, i-Ofisi yoMphathiswa we-Ecology kunye nokusiNgqongileyo ikhuphe 'Izikhokelo zokuLungiselela iNkcazelo yoLawulo lokuNcitshiswa kwamanzi kunyango lwamanzi amdaka asemaphandleni. Izibonelelo (zokuphunyezwa kovavanyo)' (Ileta yoMhlaba ye-Ofisi yeMicimbi yokuSingqongileyo 〔2019〕 No. 403), ekhuthaza ukhetho olukhethekileyo lwe-nitrogen kunye ne-phosphorus resourcing kunye nobuchwepheshe bokusetyenziswa kwamanzi omsila. Emva koko, imigangatho emitsha yokukhutshwa kwamanzi kumaphondo nakwizixeko nayo iye yanyenyisa usukelo lwazo. Ukucocwa okuphakathi kwamanzi amdaka asemaphandleni kuyagxininiswa kwaye kukhuthazwa ukusuka phezulu ukuya ezantsi, kubeka isiseko sokusetyenziswa kwemithombo elandelayo.
ISikhokelo soPhuhliso lokuSetyenziswa koMthombo waManzi amdaka ngokweNgingqi
Imigxobhozo eyenziweyo ngoku yeyona isetyenziswa kakhulu kwiteknoloji yokucocwa kogutyulo lwasekhaya emaphandleni. Ukusetyenziswa kobuchule bokusetyenziswa kwamanzi amdaka asemaphandleni e-China kusahleli kwinqanaba lomhlaba omanzi owenziweyo, idama lokuzinzisa kunye nokucocwa komhlaba wendalo. Njengoko ungcoliseko lomphezulu wezolimo kuqukwa nogutyulo lwasekhaya lwasemaphandleni lube ngowona mthombo wongcoliseko lwasemaphandleni e-China, lonke ulawulo lwesitya, ukucuthwa komthombo-pre-blocking-resourcefulness-ecological restoration iya kuba ngumkhombandlela wophuhliso wolawulo longcoliseko lwemithombo yezolimo. Ngokufanayo, ilindle lasekhaya lasemaphandleni kufuneka lisebenzise izixhobo zengingqi. Ukomeleza umsebenzi wenkonzo yezinto eziphilayo zasemaphandleni ngokuguqulwa okwenziweyo, ukudibanisa amaziko okucoca amanzi amdaka asemaphandleni, agxile kuphela ekuncitshisweni kobutyebi, kunye nezolimo ezisetyenzisiweyo, ukwazisa iinkqubo zonyango ezilungiselelwe ngokwengingqi ezihambelana nemveliso yezolimo, kunye nokubonelela ngokudlala ngokupheleleyo kwindima yolawulo, i-agro. -i-ecosystems ngokwazo zisebenza ngendlela yokunciphisa ukudaleka okungcolisekileyo kunye nokuphuma.
Oku ngasentla ngumxholo walo mbandela, umxholo ongaphezulu nceda unikele ingqalelo kumbandela olandelayo we-Li Ding ukhuseleko lokusingqongileyo ukwabelana. U-Li Ding uzibophelele kuphando kunye nophuhliso, ukwakhiwa kunye nokusebenza kwezixhobo ezidibeneyo zogutyulo lwasemaphandleni iminyaka elishumi. Ngokuqhubeka nokusungula izinto ezintsha zetekhnoloji, sizama ukwenza igalelo elincinci ekuphuculweni kokusingqongileyo komntu kwicala elinye. Li Ding ukhuseleko lokusingqongileyo uhlobo lwendlu yokucoca izixhobo zogutyulo lwelindle lunokusetyenziswa kakuhle kakhulu kuninzi lweendawo ezisemaphandleni ezinatyisiweyo.
