在选择面积大于阈值的连接要素时，需要将表达式中的 "Square Meters" 改为具体的数值，例如 "600"，因为 arcpy.Select_analysis() 函数中的表达式只能接受数字或字段名。修改后的代码如下：

import arcpy

# 输入参数
input_features = arcpy.GetParameterAsText(0)
join_field = arcpy.GetParameterAsText(1)
target_feature = arcpy.GetParameterAsText(2)
target_field = arcpy.GetParameterAsText(3)
area_threshold = arcpy.GetParameterAsText(4)

# 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
with arcpy.da.UpdateCursor(target_feature, [target_field, join_field]) as cursor:
    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[1])
        cursor.updateRow(row)

# 导出结果
