Gu Rongbin,

Currently the OGR model does not provide for changing the spatial
reference of an existing layer. It can only be established at
layer creation time (and is passed into the CreateLayer() function).

So, if you really want to change it through OGR you basically need
to copy the whole layer to a newly created layer.
