代码中有多个错误：
1. 在创建空间连接时，输出结果已经指定为"in_memory/spatial_join"，因此在SpatialJoin_analysis函数中不需要再指定输出结果。
2. 在使用SummaryStatistics工具时，需要将join_field_name和"SUM_Shape_Area"包含在一个列表中，即[[join_field_name, "SUM_Shape_Area"]]。
3. 在使用UpdateCursor更新目标要素类的目标字段时，目标字段是target_field而不是"数据"。
4. 在删除游标对象和要素图层对象时，应该使用del语句删除两个对象，即del cursor, del join_layer。

以下是修改后的代码示例：
