这个问题可以通过使用Python的类和对象来解决。下面是一个示例代码：

class Turtle:
    def __init__(self, name, area):
        self.name = name
        self.area = area
    
    def move(self, new_area):
        self.area = new_area
    
    def __str__(self):
        return f"Turtle {self.name} is in {self.area}"
    
class TurtleGathering:
    def __init__(self):
        self.turtles = []
    
    def add_turtle(self, turtle):
        self.turtles.append(turtle)
    
    def gather_turtles(self, target_area):
        gathered_turtles = []
        for turtle in self.turtles:
            if turtle.area == target_area:
                gathered_turtles.append(turtle)
        return gathered_turtles

# 创建几只龟并设置它们的区域
t1 = Turtle("Turtle 1", "Area 1")
t2 = Turtle("Turtle 2", "Area 2")
t3 = Turtle("Turtle 3", "Area 1")
t4 = Turtle("Turtle 4", "Area 3")

# 创建一个聚集对象并添加龟
gathering = TurtleGathering()
gathering.add_turtle(t1)
gathering.add_turtle(t2)
gathering.add_turtle(t3)
gathering.add_turtle(t4)

# 聚集特定区域的龟
gathered_turtles = gathering.gather_turtles("Area 1")

# 打印聚集的龟
for turtle in gathered_turtles:
    print(turtle)

上面的代码定义了一个Turtle类来表示龟，并具有名称和区域属性。还有一个TurtleGathering类，用于管理和聚集龟。它具有添加龟和聚集特定区域龟的功能。

您可以根据需要修改代码来适应您的具体需求。
