“十日”是我国上古时期以太阳为图腾的氏族部落集团，该集团与以动物为图腾、环渤海湾居住的诸部落联姻，共同从事原始的农耕生产。以“十日”为核心的农耕部落联盟与以羿为首的渔猎部落因各自经济生产方式的不同，出现了对自然界开发的不同理解，直至发生部落之间的战争，这便是“羿射十日”的真正史因。这场史前部落战争留给后世的教训异常深刻：只有尊重自然才能促进自身发展，否则，必将受到大自然的惩罚，因而，保护生态环境应是人类社会永恒关注的课题。 The “10th Day” is a clan tribal group that took the sun as its totem in ancient times. The group engaged in primitive farming with the tribes living in the totem and living in the Bohai Bay. Due to their different economic methods of production, the tribe of farming tribes with the core of the “10th” as the core and fishing and hunting tribes headed by Yi began to have different understandings on the development of nature until the wars between the tribes occurred. This is the result of “ Day ”of the real cause. The lessons left by this prehistoric tribal war for future generations are exceptionally profound. Only by respecting nature can we promote our own development or we will surely be punished by nature. Therefore, protecting the ecological environment should be the eternal concern of human society.
