Izifundo Zesimo Sezulu Esincane Emadolobheni Amakhulu: Ukuhlaziywa, Izinselele, kanye Nezixazululo
I-Pendahuluan
I-Microclimate yigama elibhekisela ezimweni zezulu endaweni encane kakhulu, njengepaki, umgwaqo omkhulu, noma ngisho nendawo yokuhlala. Emadolobheni amakhulu, i-microclimate iyisihloko esibalulekile esidinga ukufundwa okwengeziwe ngoba la madolobha anezimpawu zawo kanye nokuguquguquka kwawo okungathonya, futhi kushintshe ngisho, isimo sezinto eziphilayo zasendaweni. Njengoba ukwanda kwamadolobha, ukuguquka kwesimo sezulu, kanye nezidingo zokuphathwa okungcono kwemvelo, ukutadisha i-microclimate emadolobheni amakhulu kudlala indima ebalulekile. Lesi sihloko sizohlola ukuhlaziywa, izinselele, kanye nezixazululo ekutadisheni i-microclimate emadolobheni amakhulu.
I. Izimo Zesimo Sezulu Esincane Emadolobheni Amakhulu
1. Isenzakalo Sesiqhingi Sase-Urban Heat
Esinye sezenzakalo ezaziwayo kakhulu ezindaweni ezincane zasemadolobheni yi-Urban Heat Island (UHI), lapho amazinga okushisa ezindaweni zasemadolobheni ephakeme kunalawo asezindaweni zasemaphandleni ezizungezile. Izimbangela eziyinhloko ze-UHI yimisebenzi yabantu kanye nezinguquko ku-albedo ezibangelwa ingqalasizinda yasemadolobheni efana nokhonkolo kanye ne-asphalt, ezimunca ukukhanya kwelanga okuningi kunezitshalo.
Izifundo zikhombisile ukuthi i-UHI ingakhuphula amazinga okushisa asemadolobheni ngama-degree Celsius amaningana ngaphezu kwezindawo ezizungezile. Lokhu akugcini nje ngokuphazamisa induduzo yokushisa kodwa futhi kuthinta nezidingo zamandla zokupholisa izakhiwo, ikhwalithi yomoya, kanye nempilo yomphakathi.
2. Ithonya Lokuhlelwa Kwesakhiwo Nokwakheka Kwaso
Ukuhlelwa kanye nesakhiwo sezakhiwo nakho kudlala indima ebalulekile ekunqumeni isimo sezulu esincane sedolobha. Isibonelo, izakhiwo ezinde zingavimba ukuhamba komoya futhi zidale izindawo ezinomoya ongemuhle. Ngaphezu kwalokho, izinto zokwakha ezifana nengilazi nensimbi zingabonakalisa noma zimunce ukushisa, zithinte amazinga okushisa endawo.
II. Izinselele Ezifundweni Zesimo Sezulu Esincane
1. Ubunzima Nokuhlaziywa Kwedatha
Izifundo ze-microclimate zidinga idatha enemininingwane eminingi, okuhlanganisa izinga lokushisa, umswakama, ukuhamba komoya, kanye nemisebe yelanga ngezikali ezincane. Ukuqoqa le datha kudinga ubuchwepheshe obuyinkimbinkimbi kanye nomklamo wokutadisha ngokucophelela.
2. Ukuguquguquka Kwesikhashana Nesikhala
Izimo ze-microclimate zingashintsha ngokushesha nangokuphawulekayo phakathi namahora noma ngisho nemizuzu, okwenza ukubikezela nokuqapha kube nzima kakhulu. Lokhu kuhlukahluka kwenza kube nzima ukufeza iziphetho ezijwayelekile noma ukuthuthukisa amamodeli anembile.
III. Izindlela kanye nobuchwepheshe ezifundweni ze-Microclimate
1. Izinzwa Namathuluzi Okuqapha
Ubuchwepheshe bezinzwa zesimanje ezifana nama-drone, ama-mini-satellite, kanye neziteshi zesimo sezulu eziphathwayo zingasetshenziswa ukuqoqa idatha ye-microclimate yesikhathi sangempela. Lawa mathuluzi ayakwazi ukulinganisa ububanzi bemingcele yesimo sezulu ngezinga eliningiliziwe kakhulu.
2. Ukulingisa Ikhompyutha Nokwenza Amamodeli
Ukulingisa ikhompyutha kanye nokumodela ngezinombolo kuyizindlela ezithandwa kakhulu zokuqonda ukuguquguquka kwesimo sezulu esincane. Isofthiwe efana ne-ENVI-met kanye ne-FluidFlow ingasetshenziswa ukulingisa ukuhamba komoya, ukusatshalaliswa kokushisa, kanye nokusebenzisana phakathi kwezici ezahlukahlukene zesimo sezulu ezikalini ezincane.
IV. Izifundo Zezimo kanye Nemiphumela Ebalulekile
1. IJakarta, e-Indonesia
IJakarta ingenye yamadolobha amakhulu abhekene nesimo esibalulekile se-UHI. Izifundo zibonisa ukuthi isikhungo sedolobha sibhekene namazinga okushisa aphezulu uma kuqhathaniswa namadolobha aseduze. Lokhu kuhlaziya kusikisela ukuthi ukutshala izihlahla eziningi nokufaka uhlaza ophahleni kuyisisombululo sesikhathi eside sokunciphisa imiphumela ye-UHI.
2. ITokyo, eJapane
ITokyo iphinde iqalise uhlelo "lokwenza luhlaza" ngokwethula amapaki amaningi edolobheni kanye nezindawo eziluhlaza. Ngaphezu kwalokho, isebenzisa ubuchwepheshe bokwakha obungavikeli imvelo njengophahla oluluhlaza kanye nezindonga eziluhlaza ukusiza ekunciphiseni i-UHI.
V. Izixazululo Zokuphatha Namasu
1. Ukusetshenziswa Kwesikhala Esiluhlaza
Ukwandisa inani lesikhala esiluhlaza emadolobheni kuyisisombululo esisebenzayo esifakazelwe sokunciphisa imiphumela ye-UHI. Ukutshala izihlahla emigwaqweni, emapaki amadolobha, kanye nophahla lwezindawo eziluhlaza kungasiza ekwehliseni amazinga okushisa omhlaba.
2. Umklamo Wezakhiwo Onobungani Nemvelo
Ukusebenzisa ubuchwepheshe obufana nophahla oluluhlaza, izindonga eziluhlaza, kanye nezinto zokwakha ezine-albedo ephezulu kuyisinyathelo esibalulekile. Lokhu kuhlanganisa nokusetshenziswa kwengilazi ekhanyayo ukunciphisa ukumuncwa kokushisa kanye nokuhlelwa kwezakhiwo ukuthuthukisa ukuhamba komoya.
3. Ukuthuthukiswa Kokuhlela Indawo Nokuthutha
Ukuhlela okuhle kwedolobha kumele futhi kucabangele izici ze-microclimate. Isibonelo, ukuklama izakhiwo zendawo ezivumela ukugeleza komoya okwanele kanye nokuklama imigwaqo kanye nezindlela zokuhamba ngezinyawo ukunciphisa imiphumela yokushisa.
4. Imfundo Yomphakathi Nokuqwashisa
Ukufundisa umphakathi ngokubaluleka kwesimo sezulu esincane kanye nendlela abanganikela ngayo, isibonelo ngokutshala izihlahla noma ukunciphisa ukusetshenziswa kwezimoto zangasese, nakho kuyisu elibalulekile.
VI. Isiphetho
Ukufunda ngesimo sezulu esincane samadolobha amakhulu kuwumsebenzi oyinkimbinkimbi odinga ubuchwepheshe obuyinkimbinkimbi, idatha enemininingwane, kanye namasu okuphatha umsindo. Izenzakalo ezifana ne-Urban Heat Island zibonisa ukubaluleka kokuqonda nokuphatha isimo sezulu esincane ngempumelelo. Ukuhlanganiswa kobuchwepheshe obuthuthukisiwe, ukwakheka kwezakhiwo ezinobungani nemvelo, kanye nokuhlelwa kwedolobha okunengqondo kungasiza ekudaleni izindawo zasemadolobheni ezinempilo nezikhululekile kakhulu kubahlali. Ngokwazi okwengeziwe kanye nokubambisana phakathi kwamaqembu ahlukahlukene, izinselele ezibhekene nezifundo zesimo sezulu esincane zinganqotshwa, kudalwe amadolobha azinzile futhi aqinile ekushintsheni kwesimo sezulu.
