近日，法国国家科学研究中心Stéphen Rostain教授及其团队成员，在研究亚马逊河上游两千年的园林城市化中取得新成果。2024年1月12日出版的《科学》杂志发表了这项成果。

据研究人员介绍，厄瓜多尔亚马逊流域的乌帕诺山谷（安第斯山脉东麓丘陵地带）有一个密集的前西班牙城市中心系统。研究对该地进行了实地调查和光探测与测距(LIDAR)分析，结果显示该地为人类化的景观，其中有巨大的平台、广场和街道，它们遵循着一种特定的模式，与广泛的农业排水和梯田以及长距离的宽阔笔直的道路交织在一起。考古发掘的时间从500 BCE到300-600 CE。

最显著的景观特征是延伸数十公里的复杂道路系统，连接不同的城市中心，形成一个区域规模的网络。亚马逊河上游如此广泛的早期发展，可以与最近在墨西哥和危地马拉强调的类似的玛雅城市系统相媲美。

Abstract: A dense system of pre-Hispanic urban centers has been found in the Upano Valley of Amazonian Ecuador, in the eastern foothills of the Andes. Fieldwork and light detection and ranging (LIDAR) analysis have revealed an anthropized landscape with clusters of monumental platforms, plazas, and streets following a specific pattern intertwined with extensive agricultural drainages and terraces as well as wide straight roads running over great distances. Archaeological excavations date the occupation from around 500 BCE to between 300 and 600 CE. The most notable landscape feature is the complex road system extending over tens of kilometers, connecting the different urban centers, thus creating a regional-scale network. Such extensive early development in the Upper Amazon is comparable to similar Maya urban systems recently highlighted in Mexico and Guatemala.
