特征和几何有关系，你不想破坏

 from osgeo import ogr

    print "[ ERROR ]: datasource cannot be opened"

#
#  collect just the geometries
#  notice that we are losing reference
#  each geometry's parent feat though
#
for feat in layer:
    geom = feat.GetGeometryRef()
    geom_collection.append( geom )

#
#  try to print the
#  geometries collected
#
for g in geom_collection:
    print g.ExportToWkt()
