目(mu)前學術界對(dui)薩(sa)(sa)其城(cheng)(cheng)(cheng)的年(nian)代和(he)性(xing)(xing)質(zhi)(zhi)考證,觀點不一(yi)。《琿春(chun)縣文物(wu)志(zhi)》認(ren)為城(cheng)(cheng)(cheng)址為渤海(hai)時(shi)(shi)期(qi)軍事性(xing)(xing)山城(cheng)(cheng)(cheng)。李(li)健才在(zai)《琿春(chun)渤海(hai)古城(cheng)(cheng)(cheng)考》中,提出(chu)(chu)薩(sa)(sa)其城(cheng)(cheng)(cheng)為高句麗“柵(zha)城(cheng)(cheng)(cheng)府”,渤海(hai)穆州(zhou)或賀(he)州(zhou)州(zhou)治(zhi)。由(you)于城(cheng)(cheng)(cheng)址未經(jing)發掘,以往對(dui)城(cheng)(cheng)(cheng)址年(nian)代、性(xing)(xing)質(zhi)(zhi)的認(ren)定(ding)多依(yi)據(ju)歷史地理考證和(he)地表調查,缺(que)乏確實可信的實證依(yi)據(ju)。薩(sa)(sa)其城(cheng)(cheng)(cheng)規模(mo)很大,吉(ji)林省境內(nei)的山城(cheng)(cheng)(cheng)中少見(jian)。城(cheng)(cheng)(cheng)內(nei)出(chu)(chu)土遺物(wu)豐(feng)富,可能(neng)存(cun)在(zai)多個時(shi)(shi)期(qi)的遺存(cun)。以往學術界對(dui)大量發現于吉(ji)林延(yan)邊地區(qu)(qu)的山城(cheng)(cheng)(cheng)城(cheng)(cheng)(cheng)址年(nian)代、性(xing)(xing)質(zhi)(zhi)的認(ren)定(ding)頗具爭議,對(dui)薩(sa)(sa)其城(cheng)(cheng)(cheng)開展進一(yi)步研究,對(dui)開展高句麗疆(jiang)域,渤海(hai)行政區(qu)(qu)劃,以及吉(ji)林東(dong)部(bu)地區(qu)(qu)山城(cheng)(cheng)(cheng)的年(nian)代、性(xing)(xing)質(zhi)(zhi)研究均具有極為重要(yao)的現實意義。
