摘要: 提要：史期时期，人类社会的生产力还十分低下，自然环境对古人类体质的进化、生产的发展，以及居住范围的变化都产生了重大的影响。通过孢粉分析和对其他植物遗存的研究复原古植被特征，同时结合广汉层古土壤地球化学行为、古河流的水动力等，来综合研究金沙遗址区古环境状况，以期能为古蜀文化研究提供环境背景。研究结果表明，文化期内总体上是热带和亚热带的温暖湿润气候，同时存在着温暖湿润与温暖干旱的气候交替。Abstract: Abstract：In ancient times, due to the lower productive force of the society, the natural environment greatly influenced the evolution of ancient human being, production and residency. According to sporopollen analysis and study and reconstruction of ancient vegetations, combined with studies of the geochemical behaviors of paleosol of the Guanghan layer of the Shanxingdui site and hydrodynamic conditions of ancient rivers, the ancient environment of the Jinsha cultural site was studied in an attempt to provide the environmental background for the study of the Sichuan ancient culture. Study shows that the climate in the cultural period was generally tropical and subtropical warm-humid. Meanwhile, the warm-humid climate alternated with the warm-dry one.
