Hnub ci hluav taws xob tsim hluav taws xob yog ib txoj hauv kev hloov lub hnub ci zog rau hauv hluav taws xob hluav taws xob. Lub hnub ci zog yog ib qho ntawm cov khoom siv hluav taws xob zoo tshaj plaws thiab muaj txiaj ntsig zoo, ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv peb ib puag ncig ecological.
Lub hauv paus ntsiab lus ntawm kev tsim hluav taws xob hnub ci feem ntau yog siv lub hauv paus ntsiab lus ntawm cov nyhuv photoelectric, uas hloov lub teeb lub zog rau hauv hluav taws xob. Hnub ci vaj huam sib luag yog tsim los ntawm ntau txheej txheej ntawm cov khoom siv semiconductor, qhov twg cov hluav taws xob nqus hnub ci thiab ua kom muaj hluav taws xob. Cov hluav taws xob hauv lub hnub ci vaj huam sib luag ntws los ntawm cov xov hlau, tsim cov hluav taws xob tam sim no, uas ua tiav tag nrho cov txheej txheem hloov hluav taws xob hnub ci thiab tsim lub zog huv thiab rov ua dua tshiab.
Hnub ci hluav taws xob tsim muaj ntau yam kev siv, xws li teeb pom kev zoo, them nyiaj, cua sov, thiab lwm yam. Lub hnub ci hluav taws xob tsim hluav taws xob tuaj yeem tsis tsuas yog muab cov neeg muaj xim ntsuab, huv si, thiab ntau dua ib puag ncig tus phooj ywg lub zog, tab sis kuj txo lawv qhov kev cia siab ntawm cov pob txha pob txha thiab txo cov teeb meem hluav taws xob tam sim no hauv ntiaj teb.
Hnub ci lub zog hluav taws xob muaj ntau yam zoo, xws li lub hnub ci tsis muaj kev txwv, kev ua haujlwm ruaj khov, kev ua haujlwm yooj yim, kev saib xyuas yooj yim, thiab muaj peev xwm siv tau nyob txhua qhov chaw. Tshwj xeeb tshaj yog nyob rau hauv qhov chaw uas tsis muaj hluav taws xob, xws li Antarctica thiab cov pab pawg neeg nomadic hauv cov suab puam, lawv tuaj yeem tau txais hluav taws xob txaus los ntawm lub hnub ci hluav taws xob.
Lub hauv paus ntsiab lus ntawm kev tsim hluav taws xob hnub ci yog siv cov nyhuv photoelectric los hloov lub hnub ci zog rau hauv hluav taws xob. Hnub ci hluav taws xob tsim hluav taws xob tsis yog tsuas yog ib puag ncig tus phooj ywg thiab txuag hluav taws xob, tab sis kuj siv tau yooj yim thiab muaj ntau yam kev siv, uas muaj qhov tseem ceeb rau peb kom ua tiav kev tsim kho ntawm lub zej zog kev vam meej.
