无法使用 arcpy 生成要素 class 的子集（Python 2.7 中的 ArcGIS 库）

Question

我在使用 ArcPy 库处理 Python 中的 GIS 数据时遇到了困难。
我一直在尝试根据属性 table 的字段从特征 class 生成独立特征，该属性是代表生产性森林单位的唯一代码，但我无法完成。
我已经在其他情况下这样做了，但这次我不知道我错过了什么。
这是代码和我得到的错误：

# coding utf-8
import arcpy

arcpy.env.overwriteOutput = True
ws = r'D:\Projeto_VANT\SIG\proc_parc.gdb'
arcpy.env.workspace = ws

talhoes = r'copy_talhoes'

estados = ('SP', 'MG')
florestas = ('PROPRIA', 'PARCERIA')

arcpy.MakeFeatureLayer_management(talhoes,
                                          'talhoes_layer',
                                          """ "ESTADO" IN {} AND "FLORESTA" IN {} """.format(estados, florestas),
                                          ws)
arcpy.FeatureClassToFeatureClass_conversion(in_features = 'talhoes_layer',
                                            out_path = ws,
                                            out_name = 'talhoes1')
talhoes1 = r'talhoes1'

arcpy.AddField_management(talhoes1, 'CONCAT_T', 'TEXT')
arcpy.CalculateField_management(talhoes1, 'CONCAT_T', """ [ESTADO] & "_" & [CODIGO] & "_" & [TALHAO] """, 'VB')

with arcpy.da.SearchCursor(talhoes1, ['CONCAT_T', 'AREA']) as tal_cursor:
    for x in tal_cursor:
        print(x[0] + " " + str(x[1])) # This print is just to check if the cursor works and it does!
        arcpy.MakeFeatureLayer_management(x,
                                          'teste',
                                          """ CONCAT_T = '{}' """.format(str(x[0]))) # Apparently the problem is here!
        arcpy.CopyFeatures_management('teste',
                                      'Layer{}'.format(x[0]))

这里是错误：

Traceback (most recent call last):
  File "D:/ArcPy_Classes/Scripts/sampling_sig.py", line 32, in <module>
    """ CONCAT_T = '{}' """.format(str(x[0])))
  File "C:\Program Files (x86)\ArcGIS\Desktop10.5\ArcPy\arcpy\management.py", line 6965, in MakeFeatureLayer
    raise e
RuntimeError: Object: Error in executing tool

Answer 1

我认为问题出在您的 In 功能上。你会希望你的 in 特征是 talhoes1 因为 x 是光标对象而不是特征。

  arcpy.MakeFeatureLayer_management(talhoes1,'teste',""" CONCAT_T = 
  '{}'""".format(str(x[0])))
