这个错误是因为在使用 `arcpy.Select_analysis` 时，选择条件 `"Shape_Area > " + area_threshold` 不正确。可以尝试将其改为 `"\"Shape_Area\" > " + str(area_threshold)"`，即：

arcpy.Select_analysis("in_memory/spatial_join", "in_memory/selected_features", "\"Shape_Area\" > " + str(area_threshold))

其中，`\"Shape_Area\"` 用于表示字段名为 Shape_Area，`str(area_threshold)` 用于将输入的面积阈值转换为字符串类型。
