摘　　要：主要构建一种新型的地理网格网络,并探讨网络的拓扑性质及其逾渗动力学行为,为现实地理网络的鲁棒性研究及其构建提供参考。这个网络的特点是,在构建时引入度权重连接概率和地理距离权重连接概率。研究发现这种新型网络能够随着这两种概率及相关参数的改变,生成嵌入式无标度网络并渐进过渡到嵌入式指数网络。In this paper, a new network with geographical distance is constructed, and we discuss the network^s properties and the percolation thresholds of the networks, provide the reference for the realis- tic geographical network＇s robustness and construction. This new network is characterized by the degree- weighted connection probability and distance-weighted connection probability. By changing the ratio of the two connection probabilities, for the nearest connection, the degree distributions of the networks can change smoothly from the power-law to the exponential one.
