良渚先民受自然环境的制约和经济生活模式的决定 ,连片成串地集中分布于长江三角洲南部平原 ,良渚早中期的温干气候和适宜环境使良渚文化空前繁荣 ,但在距今 4 0 0 0年左右突然消亡。作者通过研究 ,发现在距今 4 10 0年左右存在明显的降温事件 ,降温使农作物歉收 ,食物匮乏 ,在部落间引起连绵战争 ,使良渚文化走向衰弱。而距今 360 0年左右的海平面升高 ,在长江三角洲南部平原发生沟谷海侵 ,地下水位升高 ,太湖湖泊体系迅速扩张 ,引起大洪水 ,导致良渚文化消亡。
Liangzhu ancestors were constrained by the natural environment and decided by the economic life mode. They were concentrated in a series of clusters in the southern plains of the Yangtze River Delta. The warm and dry climate and the suitable environment in the early and mid Liangzhu made the Liangzhu culture unprecedented prosperity. However, Today, the sudden death of 40 years or so. Through the research, the author found that there was a clear cooling event about 4 10 0 years ago, and that cooling caused a crop failure and food shortage and caused a series of wars between tribes to weaken the Liangzhu culture. However, the sea level rose from about 360 to the present, with the transgression of valleys and valleys in the southern plain of the Yangtze River Delta and the rapid expansion of the Taihu Lake system, which caused great floods and led to the demise of the Liangzhu Culture.
