Abstract:
Rudzi rwemusha uye kushandiswa kwepekugara ndizvo zvepakati pezvipenyu zveavian, uye zvidzidzo pamusoro pezvinhu izvi zvichabatsira kuchengetedza uye kutonga kwehuwandu hweshiri. Makumi makumi matanhatu nemanomwe akanga ari pasi rose positioning system tagged paSanmenxia Wetland yeHenan Province kuti awane ruzivo rwakadzama ruzivo rwenzvimbo munguva yechando kubva 2015 kusvika 2016. Hukuru hwemusha we swans hwakanga huri hukuru munguva yepakati yechando uye yakateverwa nenguva yekutanga uye nguva yekupedzisira, uye hukuru hwakanga hwakasiyana zvakanyanya pakati penguva nhatu dzechando. Pakanga paine misiyano yakakura mukushandiswa kwenzvimbo yekugara pakati penguva dzakasiyana dzechando. Munguva yepakutanga, maswans ainyanya kushandisa huswa hwemumvura uye nzvimbo dzezvirimwa zvinomera, uye vainyanya kuvimba nekuwedzera kwekuwedzera nekuda kwekushaikwa kwenzvimbo dzekudyira dzechisikigo panguva yepakati. Munguva yekupedzisira, swans dzainyanya kushandisa nzvimbo ichangoburwa yehuswa hwepasi. Kunze kwemvura yakadzika, kushandiswa kwemamwe mazinga emvura kwakasiyana zvakanyanya pakati penguva dzakasiyana dzechando. Munguva yekutanga yechando, maswans aifarira nzvimbo yakaderera uye yakakwirira yemvura; munguva yepakati, vainyanya munzvimbo dzepakati uye dzepamusoro pemvura uye vakashandisa nzvimbo dzose dzemvura kunze kwemvura yakadzika munguva yechando. Yakagumiswa kuti zvimwe zvinomera zvinofarirwa nemhashu, setsanga, katsi uye uswa hwebhari, uye kuti kudzika kwemvura kunofanira kunge kwakakodzera kune swans, uye mazinga emvura anosiyana pane gradient.
