解决python gdal投影坐标系转换的问题

要将xian80地理坐标系转换成投影坐标系：xian1980="""GEOGCS["GCS_Xian_1980",DATUM["Xian_1980",SPHEROID["Xia

要将xian80地理坐标系转换成投影坐标系：

xian1980 = """
GEOGCS["GCS_Xian_1980",
 DATUM["Xian_1980",
 SPHEROID["Xian_1980",6378140.0,298.257]],
 PRIMEM["Greenwich",0.0],
 UNIT["Degree",0.0174532925199433]]"""
prjreference = 'PROJCS["Xian_1980_3_Degree_GK_Zone_37",GEOGCS["GCS_Xian_1980",DATUM["D_Xian_1980",SPHEROID["Xian_1980",6378140.0,298.257]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Gauss_Kruger"],PARAMETER["False_Easting",37500000.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",111.0],PARAMETER["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]'

转换后会报错：

 latlong = transform.TransformPoint(x,y)
 File "/usr/lib/python3/dist-packages/osgeo/osr.py", line 711, in TransformPoint
 return _osr.CoordinateTransformation_TransformPoint(self, *args)
NotImplementedError: Wrong number or type of arguments for overloaded function 'CoordinateTransformation_TransformPoint'.
 Possible C/C++ prototypes are:
 OSRCoordinateTransformationShadow::TransformPoint(double [3])
 OSRCoordinateTransformationShadow::TransformPoint(double [3],double,double,double)

**想想之前也没发现过这个问题呀，最后发现之前投影坐标系：**
'PROJCS["Xian_1980_3_Degree_GK_Zone_37",GEOGCS["GCS_Xian_1980",DATUM["D_Xian_1980",SPHEROID["Xian_1980",6378140.0,298.257]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",37500000.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",111.0],PARAMETER["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]'

**不是高斯-克吕格投影而是横轴墨卡托，我想原因可能是gdal库里只能支持高斯-克吕格投影吧。**
