根据错误提示，问题出在第11行，可能是语法错误。可以检查一下第11行的代码，看看是否有语法错误。建议将第11行的双引号改成单引号，即将""Shape_Area" > " + str(area_threshold) 改成 ''Shape_Area' > ' + str(area_threshold)，因为在Python中，字符串可以用单引号或双引号表示，但是不能混用。修改后的代码如下：

import arcpy

# 输入参数
input_features = arcpy.GetParameterAsText(0)
# 连接要素
join_field = arcpy.GetParameterAsText(1)
# 连接字段
target_feature = arcpy.GetParameterAsText(2)
# 目标要素
target_field = arcpy.GetParameterAsText(3)
# 目标字段
area_threshold = arcpy.GetParameterAsText(4)
# 面积阈值

# 创建空间连接
arcpy.SpatialJoin_analysis(input_features, target_feature, "in_memory/spatial_join", "JOIN_ONE_TO_ONE", "KEEP_ALL", "", "INTERSECT")

# 选择面积大于阈值的连接要素
arcpy.Select_analysis("in_memory/spatial_join", "in_memory/selected_features", "'Shape_Area' > " + str(area_threshold))

# 统计相同连接字段值的面积总和
arcpy.Statistics_analysis("in_memory/selected_features", "in_memory/summarized_features", "Shape_Area SUM", join_field)

# 创建字典，存储连接字段值和对应的面积总和
sum_dict = {}
with arcpy.da.SearchCursor("in_memory/summarized_features", [join_field, "SUM_Shape_Area"]) as cursor:
for row in cursor:
sum_dict[row[0]] = row

# 更新目标要素中的字段值

for row in cursor:
join_value = row[1]
if join_value in sum_dict:
area_sum = sum_dict[join_value]
row[0] = str(area_sum)
