主要作用

海(hai)門(men)口遺(yi)址(zhi)(zhi)出土文物，屬銅(tong)石(shi)并(bing)用(yong)(yong)時(shi)期文化(hua)，這一(yi)(yi)遺(yi)址(zhi)(zhi)的(de)(de)(de)發(fa)(fa)(fa)現，反映(ying)出云(yun)南原始社(she)會(hui)(hui)末期之社(she)會(hui)(hui)面貌，說(shuo)明當時(shi)這里已形成一(yi)(yi)個(ge)濱水的(de)(de)(de)村(cun)落(luo)，村(cun)落(luo)房(fang)屋(wu)為一(yi)(yi)種(zhong)干欄建(jian)筑(zhu)，與近代云(yun)南一(yi)(yi)些(xie)少數民(min)族房(fang)屋(wu)相似(si)。遺(yi)址(zhi)(zhi)發(fa)(fa)(fa)現的(de)(de)(de)器(qi)物，具有(you)洱海(hai)地區(qu)新(xin)石(shi)器(qi)文化(hua)若干特征，無論石(shi)器(qi)或骨器(qi)，都磨得(de)(de)整(zheng)齊精致，陶器(qi)開始出現輪(lun)制(zhi)痕跡，說(shuo)明整(zheng)個(ge)社(she)會(hui)(hui)生產(chan)力有(you)了飛(fei)躍(yue)的(de)(de)(de)進(jin)步。特別值得(de)(de)注意的(de)(de)(de)是，發(fa)(fa)(fa)現的(de)(de)(de)14件銅(tong)器(qi)中(zhong)有(you)斧、刀、鑿(zao)裝飾品和魚鉤，還有(you)制(zhi)造銅(tong)斧的(de)(de)(de)范(fan)，標(biao)志(zhi)著當地冶(ye)金術的(de)(de)(de)發(fa)(fa)(fa)展。這些(xie)銅(tong)器(qi)雖然(ran)粗糙、簡單，但后來云(yun)南光(guang)輝燦爛的(de)(de)(de)青銅(tong)文化(hua)是從(cong)這里開始的(de)(de)(de)。由(you)于生產(chan)工(gong)具的(de)(de)(de)改造，農業(ye)、畜(chu)牧業(ye)和漁獵均很發(fa)(fa)(fa)達。遺(yi)址(zhi)(zhi)中(zhong)發(fa)(fa)(fa)現的(de)(de)(de)粳稻大(da)(da)概一(yi)(yi)直(zhi)是遠古(gu)時(shi)期云(yun)南地區(qu)栽培(pei)主要稻種(zhong)。從(cong)測定的(de)(de)(de)遺(yi)址(zhi)(zhi)形成時(shi)間看，當時(shi)云(yun)南剛(gang)(gang)剛(gang)(gang)跨進(jin)階級社(she)會(hui)(hui)的(de)(de)(de)大(da)(da)門(men)，而我國中(zhong)原地區(qu)正(zheng)處在殷商晚期。截止目(mu)前所知，海(hai)門(men)口遺(yi)址(zhi)(zhi)是云(yun)南銅(tong)石(shi)并(bing)用(yong)(yong)文化(hua)早發(fa)(fa)(fa)源地，標(biao)志(zhi)著云(yun)南地區(qu)利用(yong)(yong)金屬的(de)(de)(de)開始。
