Igipimo gishya gishingiye kuri satelite cyo kumenya ahantu inyoni zo mu mazi zirya ibyatsi ziherereye.

Incamake:

Ikwirakwizwa ry'ibiribwa ni ingenzi mu guhitamo aho biba. Inyoni zo mu mazi zikunda ibimera bikura hakiri kare (kuva ibimera bikura kugeza ku rwego rwo hejuru rw'intungamubiri) kuko izi nyoni zitanga ingufu nyinshi. Iki cyiciro cyo gukura kw'ibimera ntigifatwa neza n'ibipimo by'ibimera bikomoka kuri satelite, byibanda ku bimera by'ibimera (urugero, Ikigereranyo cy'ibimera bikura neza, EVI) cyangwa gukura kw'ibimera (urugero, itandukaniro rya EVI hagati y'itariki y'ubu n'iyabanjirije, diffEVI). Kugira ngo tunoze igena ahantu heza ho kuragira inyoni zo mu mazi zikunda ibimera, turatanga ikimenyetso gishya cyo gukura kw'ibimera gishingiye kuri satelite cyerekana ko ibimera bikura hakiri kare (ESPG). Dutekereza ko inyoni zo mu mazi zikunda ibimera hakiri kare mu gihe cyo gukura kandi tugahitamo ibimera bifite ESPG irangira nyuma mu gihe kitari icyo gukura. Dukoresha amakuru ajyanye n'ibyogajuru by'inyoni 20 zo mu bwoko bw'umweru (Anser albifrons) zibera mu gihe cy'itumba mu ruzi rwa Yangtze kugira ngo twemeze ibyo twahanuye. Twubaka uburyo rusange bwo gukwirakwiza ingagi mu bihe by'ihinga n'ibitarimo gukura, hanyuma tukagereranya imikorere ya ESPG n'ibipimo bikunze gukoreshwa mu gukura kw'ibimera (EVI na diffEVI). Mu gihe cy'ihinga, ESPG ishobora gusobanura 53% by'ihindagurika ry'ikwirakwizwa ry'inkoko, ikarusha EVI (27%) na diffEVI (34%). Mu gihe cy'ihinga, iherezo rya ESPG ni ryo ryonyine rigira ingaruka ku ikwirakwizwa ry'inkoko, risobanura 25% by'itandukaniro (ESPG: AUC = 0.78; EVI: AUC = 0.58; diffEVI: AUC = 0.58). Ikimenyetso gishya cyo gukura kw'ibimera ESPG gishobora gukoreshwa mu kunoza uburyo bwo gukwirakwiza inyoni zo mu mazi zirya ibyatsi bityo tugashyigikira ingamba zo kubungabunga inyoni zo mu mazi no gucunga ibishanga.
