基于复杂网络-空间句法的生态网络时空演变特征分析
Analysis of spatiotemporal evolution characteristics of ecological networks based on complex network-spatial syntax
摘要
Abstract
Based on the land use and DEM data of Xuzhou planning area in 1985,1990,2000,2010 and 2020,the MSPA-MCR-circuit theory model was used five potential ecological corridors were identified,the evolution characteristics and ecological benefits of ecological networks were analyzed by complex network and space syntax.The results showed that:(1)The area of ecological core patch decreased by 23.87 km2 during 35 years,and the area of the bridge area as the connecting core patch decreased by 0.21 km2,it showed that the habitat plaque fragmentation was increasing;(2)The overall ecological network of the study area was dense in the northeast and sparse in the southwest.With the continuous expansion of urban construction land,the ecological sources and corridors of the human activity-intensive areas in the southwest tended to shrink;(3)The optimal network connectivity and stability was in 1990,followed by in 2000,2020,1985 and 2010,the highest degree of network fragmentation in 2010,more vulnerable after being destroyed;(4)The southwest corridor passed through the edge of the urban area with a large cumulative resistance value,low integration and selection of local networks.It is suggested to strengthen the source restoration and corridor optimization in this region,and repair Dacheng Mountain in the northwest to improve the information exchange in the northwest,southwest and northeast.关键词
