目前(qian)學術界(jie)對(dui)薩其(qi)城(cheng)(cheng)的(de)(de)(de)年代和性質(zhi)(zhi)考(kao)(kao)證(zheng),觀點不一。《琿春縣文物志》認(ren)為城(cheng)(cheng)址(zhi)為渤(bo)海時期軍事(shi)性山城(cheng)(cheng)。李健才在《琿春渤(bo)海古城(cheng)(cheng)考(kao)(kao)》中(zhong)(zhong),提(ti)出薩其(qi)城(cheng)(cheng)為高句麗(li)“柵(zha)城(cheng)(cheng)府”,渤(bo)海穆州(zhou)或賀州(zhou)州(zhou)治(zhi)。由于(yu)城(cheng)(cheng)址(zhi)未經發掘,以往對(dui)城(cheng)(cheng)址(zhi)年代、性質(zhi)(zhi)的(de)(de)(de)認(ren)定(ding)多依據(ju)歷史地(di)理考(kao)(kao)證(zheng)和地(di)表調查,缺乏確實(shi)可信的(de)(de)(de)實(shi)證(zheng)依據(ju)。薩其(qi)城(cheng)(cheng)規模很(hen)大,吉(ji)林省境內的(de)(de)(de)山城(cheng)(cheng)中(zhong)(zhong)少見。城(cheng)(cheng)內出土遺物豐富,可能存(cun)在多個時期的(de)(de)(de)遺存(cun)。以往學術界(jie)對(dui)大量發現于(yu)吉(ji)林延邊地(di)區(qu)的(de)(de)(de)山城(cheng)(cheng)城(cheng)(cheng)址(zhi)年代、性質(zhi)(zhi)的(de)(de)(de)認(ren)定(ding)頗具(ju)爭議,對(dui)薩其(qi)城(cheng)(cheng)開展進一步研(yan)究(jiu),對(dui)開展高句麗(li)疆(jiang)域,渤(bo)海行政區(qu)劃,以及(ji)吉(ji)林東(dong)部(bu)地(di)區(qu)山城(cheng)(cheng)的(de)(de)(de)年代、性質(zhi)(zhi)研(yan)究(jiu)均(jun)具(ju)有極為重要(yao)的(de)(de)(de)現實(shi)意義。
