摘　　要：为了解决市域生态网络结构优化时网络节点结构重要性评价无依据等问题,文中以图论和复杂网络理论为基础,提出以冗余度为评价指标的生态节点结构重要性评价方法,并应用至鹤岗市。研究表明生态节点结构越复杂,连接其他节点且构成闭合回路越多,结构重要性就越高。冗余度可从全局角度计算每个生态节点的结构重要度从而判断节点间的相对重要程度。该方法可为国土空间规划“三区协调”和相关生态规划提供决策依据。In order to overcome the problem that the shortcoming evaluation of the importance of the network node structure during the optimization of the urban ecological network structure,based on graph theory and complex network theory, this paper proposes an ecological node structural importance evaluation method with redundancy as the evaluation index. The evaluation method is applied to Hegang City. The study shows that the more complex the structure of ecological nodes and the more the number of closed loops connected to other nodes, the higher the structural importance. This method can calculate and rank the structural importance of each ecological node from a global perspective, which is helpful to judge the relative importance of nodes within the same importance level.Redundancy can calculate the structural importance of each ecological node from a global perspective to determine the relative importance of nodes. This method can provide decision-making basis for the "three-zone coordination" of territorial and spatial planning and related ecological planning.
