Iziteshi zikagesi ngombono wami zidonsa amehlo, njengoba ubuhle bazo benza kube nzima ukubalekela emehlweni abantu. Kodwa-ke, e-Greater Khingan engenamkhawulo namahlathi avundile, kunzima ukucabanga ukuthi isiteshi samandla kagesi esinomqondo oyimfihlakalo sizofihlwa kanjani ehlathini lasendle. Mhlawumbe ngenxa yendawo yaso eyingqayizivele necashile, lesi “siteshi sikagesi esisenyakatho kakhulu eChina” saziwa isikhathi eside njengenganekwane.
Emgwaqweni oyi-100km ukusuka e-Huma County ukuya eningizimu, akukho lutho oluvame kakhulu kunendawo yehlathi lezintaba endaweni yehlathi lase-Greater Khingan. Ukushintsha kwezinkathi zonyaka kuba golide ekwindla, kodwa awukho umkhondo weziteshi zokuphehla amandla ngamanzi emgwaqeni. Lapho sifika eKuanhe Village, ngokuqondiswa, sathola “uphawu” lwesiteshi sikagesi esingaziwa.
Naphezu kokuba indawo ezungezile, isiteshi samandla kagesi esisenyakatho kunazo zonke e-China, nakuba sifihlwe ezindaweni ezivundile zase-Xing'an ngenxa yendawo yaso e-Taoyuan Peak, sasike saba nomuzwa ngenxa yokuba kude nokuthula kwaso.
Uma yonke into idinga isikhathi nendawo evumayo, khona-ke iTaoyuanfeng Hydropower Station isivele yasizakala ngezinzuzo zendawo. Ngosizo lwezintaba eziphakeme eziqhubekayo zeWuhua Mountain kanye nokugeleza kwamanzi amaningi futhi asheshayo omfula odumile wase-Heilongjiang, uMfula iKuanhe, uqhele ngamakhilomitha angaphansi kwe-10 ukusuka emfuleni osemngceleni ophakathi kweChina neRussia, i-Heilongjiang, futhi iseduze nengxenye encane yetheku elikhulu kunawo wonke emhlabeni, i-"Dulying" engaziwa, okuyi-kilometer engu-0 futhi engaziwa. isiteshi samandla kagesi ophehlwa ngamanzi sifihlwe ezintabeni kodwa sisebenzisa zonke izinzuzo zemvelo zendawo ezungezile.
“Njengomphefumulo” weziteshi zokuphehla ugesi ngamanzi, uMfula iKuanhe unikeza amandla abaluleke kakhulu okukhiqiza ugesi ngokuboleka amanzi. Njengomngenela oyinhloko we-Heilongjiang, i-Kuan River isuka endaweni eyintaba ephakeme ngamamitha angama-624.8 emngceleni womfula wezintaba ze-Huma County. Amanzi ageleza enyakatho yeHuma County kanye nelokishi laseSanka, bese egelezela e-Heilongjiang ebangeni eliyikhilomitha elilodwa enyakatho yelokishi laseSanka. Umfula iKuanhe ngokwawo nawo unemingenela eminingi, esukela ngobubanzi obusuka kumamitha ayi-5 ukuya kumamitha angama-26, ngenxa yokugeleza ngokushesha kwamanzi - isilinganiso sokugeleza kwesilinganiso esingu-13.1 cubic metres ngomzuzwana - esihlinzeka ngemfuneko yokusungulwa kwesiteshi sokuphehla ugesi ngamanzi.
Kwakhiwe inkundla yokubuka eyingqayizivele esiqongweni seNtaba iWuhua, lapho isiteshi sikagesi esiphehlwa ngamanzi, sibheke udedangendlale wedamu lonke.
Emuva ngo-1991, umanduleli walesi siteshi esingaqondakali kancane iTaoyuanfeng Hydropower Station sasinegama lesimanje - iTuanjie Hydropower Station eHuma County. Ekuqaleni kokwakhiwa kweziteshi eziphehla ugesi ngamanzi, umqondo wawugxile ekuphehleni ugesi, kuyilapho kubhekwa ukusetshenziswa okuphelele kokulawula izikhukhula, ukufuywa kwezinhlanzi, kanye neminye imiklamo emikhulu yokonga amanzi kanye nezindawo zokuphehla ugesi ngamanzi.
Indawo yokugeza amanzi echibini ingamakhilomitha-skwele ayi-1062, futhi iyakwazi ukugcina i-cubic metres eyizigidi eziyi-145. Idamu elikhulu lingamamitha angu-229.20 ukuphakama, i-wave wall crest ingamamitha angu-230.40 ukuphakama, idamu elikhulu lingamamitha angu-266 ubude, idamu elisizayo lingamamitha angu-370 ubude, kanti umthamo ofakiwe wesiteshi sikagesi ungu-3 X 3500 kilowatts. Izinga lezamcolo ledizayini yobunjiniyela iba kanye njalo eminyakeni engama-200.
Nokho, selokhu kwaqala ukwakhiwa ngokusemthethweni ngo-December 18, 1992, ngenxa yezinkinga zezimali, kwaba nezikhathi zokwehla nokwenyuka okuningana emsebenzini wokwakha. Ekugcineni, ngo-July 18, 2002, ngemva kweminyaka eyishumi, ukuhlola nokukhiqizwa kukagesi kwaba yimpumelelo, kwavala igebe lokungaphehli ugesi enyakatho yeChina. Kuze kube manje, lesi siteshi sikagesi esisenyakatho impela esifihlwe e-Greater Khingan evundile “sesilawule” ingxenye esenyakatho yeChina.
Ngokwakhiwa komgwaqo oyisicaba wosimende manje, izinyathelo zifinyelela kalula maphakathi nentaba. Ipulatifomu ephakeme yedamu, efihlwe izintaba eziphakeme, ekugcineni yaphakamisa iveyili yehlathi eliminyene futhi yama phambi kwazo. Wathi eqalaza engalindele wema phezu kwedamu waphenduka. Ibhilidi lefemu belifihlwe phakathi kwezihlahla phansi, okubonakala sengathi kuphansi kodwa okuhambisana nokuchitheka kwedamu. Kusukela ezakhiweni ezisele ezisekelayo, umuntu angacabanga ngezinga elikhulu lale ndawo.
Ukusondela edamini, nakuba lingemuhle “njengomhosha ophakeme ophuma e-Pinghu” wemihosha Emithathu, kusenzima ukufihla indawo yayo ebabazekayo “yezintaba eziphakeme eziphuma e-Pinghu”. Intaba ezungezile iWuhua sekuyisikhathi eside imbozwe izingqimba zehlathi ngaphansi komoya wasekwindla ovunguza uBuddha, uguqula ukhahlamba lwezintaba lube imibala ehlukahlukene. Lawa mabhuloki anemibala emibalabala abonakala ebonakala futhi aphinde abelwe indawo ebanzi yamanzi edamu, okuvumela le ndawo enemibala yasekwindla ukuthi ibonakale emanzini, yenze ukugoqeka okubonakalayo kwendawo, kwelula isithombe esiphelele samanzi.
Abakhi bangaphambili baqopha izintaba nemigwaqo, benza ichibi eliphelele lentaba kanye neNtaba Eyisihlanu Yezimbali kanye nedamu. Nakuba wawungowokwenziwa, wawufana nendalo engokwemvelo ngempela. Eduze kwentaba eseduze nedamu, kusabonakala imikhondo yokumbiwa, futhi ichibi eliphambi kwalo nalo linetheku elikhulu lamanzi anokuthula “alisalele” buthule lapha ngenxa yokunqwabelana kwamanzi omfula abanzi anikezwa imvelo.
Akukhona nje kuphela ukuthi bushelelezi futhi abuvimbeli, kodwa ngaphansi kwamanzi ahlanzekile, kukhona nezinhlanzi eziningi ze-reservoir ezibhukuda ngokukhululekile. “Njengozakwethu ongcono kakhulu” wokongiwa kwamanzi, inhlanzi echibini elisechibini ayikwazi nje ukuhlanza umthombo wamanzi, kodwa futhi inikeze abantu bendawo inyama yenhlanzi emnandi ngokwedlulele. Eduze kwesitebhisi setshe esincane eduze kwedamu, kwamiswa isikali esilinganisa ukuphakama kwezinga lamanzi ukusuka phezulu kuya phansi, okwake kwaba “iphaseji elizinikele lokusebenza” lokuthola izinga lamanzi. Ngalesi sikhathi, kwaba yindlela enqamulelayo kubantu bendawo ukwehlela phezu kweqhwa echibini ebusika. Ngokumba imigodi yeqhwa phezu kweqhwa, izinhlanzi ezinamakhanda agqamile zingaluma ingwegwe, ikwenze kube “ukulunywa okumnandi” okungajwayelekile ebusika.
Njengoba ihamba onqenqemeni lwedamu, idamu lakha ijika elimangalisayo lokubukwa kwechibi kanye nombono walo. Ilanga lasekwindla elifudumele alisacwazi futhi likhanya njengehlobo, likhipha umbala osawolintshi ofudumele echibini. Ngaphansi komoya opholile opholile, ama-ripples awolintshi athambile enza ama-ripples angajulile. Ngenkathi ngisabuka indawo yamanzi eguquguquka kancane, ngathola ngephutha inkundla yokubuka ehlukile emelene neNtaba iWuhua, elinganiselwa ukuthi iyindawo esiqongweni sentaba enombono omuhle kakhulu.
Maphakathi nentaba, kwavulwa enye indlela ukuze kuqhutshekwe nokugada kwentaba. Ngenxa yamahlathi asehlobo aluhlaza, inkundla ebomvu, eyayivele ivelele kakhulu, manje yayisimbozwe ihlathi eliminyene futhi kunzima ukuyithola. Ngokuqondiswa abantu bendawo, kwatholakala “uphawu oluyimfihlo” - ehlathini lezintaba lapho sasifuna khona indlela yethu, kwakukhona insimu enkulu yommbila eminyene ngakwesokunxele somgwaqo owubhuqu ogelezayo, Landela amasimu ommbila futhi uthole indlela elula egandaywe ngezitini ezibomvu eziyimfihlo, eholela kule nkundla ebomvu engaqondakali ephezu kwentaba.
Ngena ngokushesha etendeni, futhi ngokuphazima kweso, kwembuleka intuthu ebabazekayo nobukhulu bechibi, elizungezwe amasimu avundile angapheli namahlathi aminyene. Ukukhuphuka ileli yokhuni ukuya esitezi sesibili se-pavilion, ukubuka kuba banzi nakakhulu. Ukukhanya kwelanga lasekwindla kumaphrojekthi phezu kwamanzi, okwethula imibala ehlukahlukene eluhlaza okwesibhakabhaka. Kuzolile futhi akumangalisi, futhi kuhambisana nezintaba namahlathi nhlangothi zombili. Ubuhle nobuhle bendawo yechibi kunzima ukuthwebula ngokugcwele ngomzuzwana.
Kungazelelwe, kwavela ukukhanya okusiliva emanzini lapho kushona ilanga, futhi abantu bendawo bathi izinhlanzi zazibuthana ndawonye ekushiseni kwelanga, zigxuma ziphuma emanzini. Ukukhanya okuyisiliva kwakukhanya ngokucwayiza kwamazenga ezinhlanzi, futhi lapho kuthulekile, kwakuzwakala umsindo omncane womoya wasekwindla ovunguza ezihlahleni nhlangothi zombili.
