以常德市桃源县森林资源二类调查数据所构建出森林景观斑块耦合网络为基础,为研究森林景观斑块耦合网络节点关键程度,并为森林景观斑块耦合网络结构熵筛选适合的计算指标,分别选取度数和介数对同一森林景观斑块耦合网络进行节点关键程度评价,利用PAJEK及ARCGIS软件进行计算关键程度计算,通过对计算结果的对比分析,其结果表明:(1)介数法和度值法均反映了森林景观斑块耦合网络的无标度性,即森林景观斑块耦合网络中大多数斑块对于整个网络的影响度较小,只有少数斑块对网络的影响较大,一旦这些影响较大的斑块被破坏,则整个网络将会面临崩溃。(2)2种方法的侧重点不同,度值法仅从节点周围相邻的局部关...

Based on the forest landscape patches coupling network constructed by using second survey data collected from forest resources of Taoyuan county Changde city, importance of links in the forest landscape patches coupling network is explored and also proper parameters for choosing structural entropy of it are confined. Dimensionality and betweeness are adopted to assess the importance of links toward the same forest landscape patches coupling network taking advantage of software like PAJEK and ARCGIS to work out the degree of importance. Through analysis and comparison of results, it shows that:...
