河姆渡人的生活世界及其可能去向

以干栏式木屋为标识的河姆渡稻作文明，不但有其纵向传承而具体表现为四个文化层的叠压，而且在一定范围内向外拓展，因而在河姆渡遗址附近，比较密集地分布着30多处属于河姆渡文化范畴之内的史前文化遗址。河姆渡文化的生成与繁荣，既得益于史前时期姚江流域相对优越的生态环境，也因为其生态环境的恶化而趋于衰微。此后，河姆渡人虽未悉数逃离姚江流域，但确实有相当部分迫于生存压力而南迁，甚至渡海越洋而去。

The Living Environment of the Ho-mu-to Prehistoric Man and Their Migration

Ho-mu-to Rice Civilization which is presented by four continous cultural layers and marked by stilt style architecture is not only carried out vertically, but also expands outward in a certain range. Therefore, there are more than 30 prehistoric cultural relics which belong to the cultural category in the vicinity of Ho-mu-to Site. The formation and prosperity of Ho-mu-to Culture benefited from the superior geographical environment of Yao River Basin. However, the Ho-mu-to culture has gradually declined due to the deterioration of the biological environment. After the deterioration, a large number of them did move southward or sail away because of survival pressure, though not all of them have fled away from the Yao River Basin.
