Maitiro ekutama kwechirimo, kushandiswa kwenzvimbo dzekugara, uye mamiriro ekuchengetedza nzvimbo dzekumira kwemhando mbiri dzeshiri dzemumvura dziri kuramba dzichiri muchando muChina sezvakaratidzwa nesatellite tracking.

Pfupiso:

Shiri dzemumvura dzinotama dzeEast Asia dzakaderera zvikuru kubvira kuma1950, kunyanya huwandu hwevanhu vanogara muchando muChina. Kuchengetedza mhuka kunokanganiswa zvakanyanya nekushaikwa kweruzivo rwekutanga nezvemafambiro ekutama nenzvimbo dzekumira. Chidzidzo ichi chinoshandisa matekiniki ekutevera satellite uye ongororo yepamusoro yenzvimbo kuti iongorore kutama kwechirimo kweshiri dzemumvura dzinonzi greater white-fronted goose (Anser albifrons) netundra bean goose (Anser serrirostris) dzichigara muchando murwizi rweYangtze. Zvichibva panzira makumi maviri nemana dzakawanikwa kubva kushiri dzemumvura makumi maviri nerimwe muchirimo cha2015 na2016, takaona kuti Northeast China Plain ndiyo nzvimbo inonyanya kushandiswa yekumira panguva yekutama, neshiri dzemumvura dzichigara kwemwedzi unopfuura mumwe. Dunhu iri rakagadzirwawo zvakanyanya pakurima, zvichiratidza kuti pane chikonzero chekuderera kweshiri dzemumvura dzeEast Asia dzinogara muchando muChina. Kudzivirirwa kwemvura inoshandiswa senzvimbo yekurara, kunyanya idzo dzakakomberedzwa nenzvimbo dzinotsvaga chikafu zvakanyanya, kwakakosha kuti shiri dzemumvura dzirarame. Nzvimbo inodarika 90% yenzvimbo huru inoshandiswa panguva yekutama kwechirimo haina kuchengetedzwa. Tinokurudzira kuti ongororo dzepasi dzemangwana dzitarise nzvimbo idzi kuti dzisimbise kukosha kwadzo kune shiri dzemumvura dzinotama pahuwandu hwevanhu, uye nzvimbo yekurara pakati penzvimbo dzakakosha dzinofanira kubatanidzwa munetwork yenzvimbo dzakachengetedzwa dziri munzira yekubhururuka. Uyezve, kurwisana pakati peshiri nevanhu munzvimbo yekumira pakati penzvimbo kunofanirwa kuongororwa zvakanyanya. Chidzidzo chedu chinoratidza kuti kuteverwa kwemasetilaiti pamwe chete nekuongorora kwenzvimbo kunogona kupa sei ruzivo rwakakosha rwunodiwa kuti kuvandudza kuchengetedzwa kwemarudzi anotama ari kudzikira.
