Abstract:
Echibini lase-Poyang, indawo enkulu kunazo zonke nengenye yezindawo zasebusika ezibaluleke kakhulu ku-East Asian-Australasian Flyway, izimfunda ze-Carex (Carex cinerascens Kük) zihlinzeka ngomthombo wokudla oyinhloko wamahansi asebusika. Nokho, ngenxa yokuqina kokulawulwa kwemifula kanye nezigigaba zesimo sezulu esibi kakhulu njengesomiso, ubufakazi bokubheka buphakamisa ukuthi ukuvumelanisa kokufuduka kwamahansi kanye ne-Carex phenology bekungeke kugcinwe ngaphandle kokungenelela komuntu, okubeka engcupheni enkulu yokuntuleka kokudla ngesikhathi sasebusika. Ngakho-ke, ukubaluleka kwamanje kwezokongiwa kwemvelo kule ndawo ye-Ramsar kushintshelwa ekuthuthukisweni kwezizinda ezimanzi ukuze kuqinisekiswe ikhwalithi yokudla efanelekile. Ukuqonda ukudla okuthandwayo kwamahansi asebusika kuyisihluthulelo sokuphatha kahle izimfunda ezimanzi. Njengoba isigaba sokukhula kanye nezinga lezakhi zezitshalo zokudla kuyizici ezibalulekile ezithonya ukukhethwa kokudla kwezilwane ezidla uhlaza, kulolu cwaningo, senze isampula yokudla esikhethwayo ngokulandela izindlela zokudla ze-Greater White-fronted Goose (n = 84) kanye ne-Bean Goose (n = 34) ukuze silinganisele "ifasitela lokudla" ngokwezinga leprotheyini, ukuphakama kwesitshalo, iwindi lamandla. Ngaphezu kwalokho, sisungule ubudlelwano phakathi kwalokhu okuguquguqukayo okuthathu okungenhla kwe-Carex okusekelwe esilinganisweni se-in-situ. Imiphumela ibonisa ukuthi amahansi athanda izitshalo ezinobude obusuka ku-2.4 kuya ku-25.0 cm, ezinamaphrotheni asuka ku-13.9 kuya ku-25.2 %, namandla asuka ku-1440.0 kuya ku-1813.6 KJ/100 g. Ngenkathi okuqukethwe kwamandla ezitshalo kukhuphuka ngobude, ubudlelwano bezinga leprotheyini ubude bubi. Amajika okukhula aphambene abonisa inselele yokonga ukugcina ibhalansi ethambile phakathi kwenani nezidingo zekhwalithi zamahansi asebusika. Ukuphathwa kwe-Carex meadow, njengokugunda, kufanele kugxile ekwandiseni isikhathi sokusebenza ukuze kukhuliswe ukutholakala kwamandla ngenkathi kugcinwa izinga elifanele lamaphrotheni ukuze ziphile isikhathi eside, zizalane futhi ziphile.
