四川盆地地处长江上游,东起巫山,南临大娄山和大凉山,西到邛崃山和岷山,北至大巴山和米仓山,海拔1000～3000米,盆地中部为200～750米的丘陵平原和山地。盆地内河流众多,北有岷江、沱江和嘉陵江三大水系及各支流,由于新构造运动的影响,盆地呈西北一东南倾斜,四周河流汇集盆地中,使盆地长期受到切割侵蚀,形成相对封闭的丘陵盆地,更新世的堆积不多。四川盆地有记载的旧石器考古调查始于1913年,华西大学博物馆的埃德加等人沿长江流域进行调查,纳尔逊等人在20年代亦做过调
Sichuan Basin is located in the upper reaches of the Yangtze River, east of Wushan, South Dalaoshan and Daliangshan, west to the Qionglai Mountain and Minshan, Dabashan and Micangshan north, 1000 to 3000 meters above sea level, the central basin of 200 to 750 meters Hilly plains and mountains. Due to the large number of rivers in the basin, there are three major river systems and tributaries of the Minjiang, Tuojiang and Jialing rivers in the north. Due to the influence of the neotectonic movement, the basin presents a southeast to southeast of the northwest. The rivers around the basin converge in the basin, causing the basin to be cut and eroded for a long time to form a relatively closed Hilly basins, Pleistocene accumulation of small. The Paleolithic archeology survey documented in the Sichuan Basin dates back to 1913. Edgar et al at the Huaxi University Museum conducted a survey along the Yangtze River and Nelson et al.
