Pfupiso:

Nzvimbo dzekumba uye kushandiswa kwenzvimbo dzekugara ndizvo zvinhu zvikuru zvekuchengetedza nharaunda yeshiri, uye zvidzidzo pamusoro pezvinhu izvi zvichabatsira mukuchengetedza nekutarisira huwandu hweshiri. Makumi matanhatu nenomwe eshiri dzaive pasi rose dzakanyorwa paSanmenxia Wetland yeHenan Province kuti dziwane ruzivo rwakadzama rwenzvimbo munguva yechando kubva muna 2015 kusvika 2016. Hukuru hwenzvimbo dzeshiri dzaivepo hwaive hukuru munguva yepakati pechando uye hwakateverwa nenguva yekutanga nenguva yekupedzisira, uye hukuru hwaive hwakasiyana zvakanyanya pakati penguva nhatu dzechando. Paive nemisiyano yakakura mukushandiswa kwenzvimbo pakati penguva dzakasiyana dzechando. Munguva yekutanga, maswans ainyanya kushandisa huswa hwemumvura nenzvimbo dzemiti dzinomera, uye ainyanya kuvimba nekuwedzera kwekugadzira nekuda kwekushaikwa kwenzvimbo dzekudyisa dzechisikigo munguva yepakati. Munguva yekupedzisira, maswans ainyanya kushandisa nzvimbo itsva dzehuswa hwepasi. Kunze kwemvura yakadzika, kushandiswa kwemamwe mazinga emvura kwaive kwakasiyana zvakanyanya pakati penguva dzakasiyana dzechando. Munguva yekutanga yechando, maswans aifarira nzvimbo dzakaderera nedzakakwirira dzemvura; Munguva yepakati, dzainyanya kuva munzvimbo dzine mvura iri pakati nepakati uye dzakakwirira uye dzaishandisa nzvimbo dzese dzine mvura iri pakati nepakati kunze kwenzvimbo ine mvura yakadzika munguva yechando yekupedzisira. Zvakagumiswa kuti mimwe miti inofarirwa neshiri dzemhando ye "swans", dzakadai se "tsanga", "cattails" ne "barnyard grass", uye kuti kudzika kwemvura kunofanirwa kukodzera shiri dzemhando ye "swans", nehuwandu hwemvura huchisiyana zvichienderana ne "gradient".
