这个错误是缩进错误，你需要检查第18行到23行的代码缩进是否正确。正确的代码应该是这样的：

# 遍历输出要素类中的要素
with arcpy.da.UpdateCursor(output_feature_class, field_list) as cursor:
    for row in cursor:
        # 如果要素面积大于最小面积，则进行合并
        if row[0] > min_area:
            # 创建合并字段的键值
            merge_key = tuple([row[field_list.index(f)] for f in merge_fields.split(";")])
            # 如果合并字段的键值不存在，则添加到字典中
            if merge_key not in merge_dict:
                merge_dict[merge_key] = []
            # 将当前要素的连接字段值添加到字典中
            join_values = [row[field_list.index(f)] for f in join_fields.split(";")]
            merge_dict[merge_key].append(join_values)
        # 删除不符合条件的要素
        else:
            cursor.deleteRow()

另外，你还需要检查代码中是否存在其他的缩进错误。
