主要作用

海門口(kou)遺(yi)(yi)址出(chu)土文物，屬銅(tong)(tong)石并用(yong)時期(qi)文化(hua)(hua)，這(zhe)(zhe)一(yi)遺(yi)(yi)址的(de)發(fa)現(xian)，反映出(chu)云南原始(shi)社(she)會(hui)末期(qi)之社(she)會(hui)面貌，說明當(dang)(dang)時這(zhe)(zhe)里(li)已(yi)形(xing)成(cheng)一(yi)個(ge)(ge)濱水的(de)村落，村落房屋(wu)(wu)為一(yi)種干欄建筑(zhu)，與近代云南一(yi)些少數民族(zu)房屋(wu)(wu)相似。遺(yi)(yi)址發(fa)現(xian)的(de)器(qi)物，具有(you)(you)洱(er)海地(di)區新石器(qi)文化(hua)(hua)若干特征，無論石器(qi)或骨器(qi)，都(dou)磨得(de)整齊精致，陶器(qi)開(kai)始(shi)出(chu)現(xian)輪制(zhi)痕跡(ji)，說明整個(ge)(ge)社(she)會(hui)生產力(li)有(you)(you)了飛躍的(de)進(jin)步(bu)。特別值得(de)注意的(de)是，發(fa)現(xian)的(de)14件銅(tong)(tong)器(qi)中有(you)(you)斧、刀、鑿(zao)裝飾品和(he)魚(yu)鉤，還有(you)(you)制(zhi)造銅(tong)(tong)斧的(de)范，標志著當(dang)(dang)地(di)冶金術的(de)發(fa)展。這(zhe)(zhe)些銅(tong)(tong)器(qi)雖然(ran)粗糙、簡單，但后來云南光輝燦爛的(de)青銅(tong)(tong)文化(hua)(hua)是從這(zhe)(zhe)里(li)開(kai)始(shi)的(de)。由于(yu)生產工具的(de)改造，農業、畜牧業和(he)漁獵均很發(fa)達(da)。遺(yi)(yi)址中發(fa)現(xian)的(de)粳稻大(da)概一(yi)直是遠(yuan)古時期(qi)云南地(di)區栽培主要(yao)稻種。從測定的(de)遺(yi)(yi)址形(xing)成(cheng)時間看，當(dang)(dang)時云南剛(gang)剛(gang)跨進(jin)階級社(she)會(hui)的(de)大(da)門，而(er)我國(guo)中原地(di)區正處在(zai)殷商晚(wan)期(qi)。截止(zhi)目前(qian)所知，海門口(kou)遺(yi)(yi)址是云南銅(tong)(tong)石并用(yong)文化(hua)(hua)早發(fa)源地(di)，標志著云南地(di)區利(li)用(yong)金屬的(de)開(kai)始(shi)。
