Inspiration of western environmental migration theories

More and more attention and concern were put on the migration phenomenon caused by environmental changes. However, many of the problems on migration caused by environment had not yet reached a consensus. Environmental migrants happened due to environmental changes, but in many cases, environmental change was not a sufficient condition. Based on summarizing environment migration theories, the paper indicated that social vulnerability theory could better explain how environmental changes affected immigration, comparing with others. The paper also pointed out that although different from international environmental migration, Chinese environmental migration was carried out under the guidance of the government and organized also, these theories still offered references.
