近年来，地理网络受到了广泛的关注，研究表明，由于地理网络中存在大量的低阶环，使得地理网络在节点失效时比没有地理约束的网络更脆弱。本文提出了一种挖空策略来打破地理网络中的低阶环，使其形成高阶环，从而使网络在保持低成本的同时具有更强的鲁棒性。该策略的有效性进行了研究分析和数值。空洞化策略可以应用于危机时期的真实的地理系统。
Geographical networks have attracted much attention recently, and it has been shown that they are more fragile under node failures than those without geographical constraints, due to the large amount of small-order cycles in these networks. In this paper, a hollowing strategy is proposed to break the small-order cycles in geographical networks and make them form higher-order cycles, thus making the networks more robust, at the same time keeping the cost low. The validity of the strategy is investigated both analytically and numerically. The hollowing strategy could be applicable in real geographical systems in times of crisis.
