瓯江流域温州段聚落空间网络结构特征演变

Evolution of the settlement spatial network structure characteristics in Wenzhou district of Oujiang River Basin

为了探究流域内地形复杂多样但社会经济发达区域聚落空间网络的演变特征,选取瓯江流域温州段为研究区,首先构建了该区域聚落空间网络,并选取度、聚集系数、局部重要性等评价指标,研究了实验区2000—2020年的聚落空间网络结构特征演变;然后,通过构建经济空间网络并结合社会经济统计数据,分析研究了影响瓯江流域温州段聚落空间网络特征变化的驱动因素.结果表明:1)温州聚落空间网络联系紧密;2)研究时段前10年网络结构变化较后10年大;3)温州聚落发展不平衡,瓯江南岸对周边地区的吸引力大且持续增长等;4)地形和经济水平是温州聚落空间网络结构形成的主要影响因素,地势低平、经济发达地区聚落集中分布且中心性强.最终得到温州聚落空间网络的结构特征演变与地形、水系、人口增长、经济发展、城镇化建设等密切相关的结论.

In order to explore the evolution characteristics of settlement spatial network in the region with complex and diverse terrain but developed social economy,Wenzhou district of Oujiang River Basin was selected as the research area.Firstly,the settlement spatial network of the study area was constructed,and the structural characteristics evolution of the settlement spatial network in the experimental area from 2000 to 2020 was analyzed by selecting evaluation indexes such as degree,aggregation coefficient and local significance.Then,by constructing the economic spatial network and combining with the social economic statistical data,the driving factors affecting the characteristics of the spatial network in Wenzhou district of Oujiang River Basin were analyzed and invetigated.The results showed that:1)The settlement spatial network in Wenzhou was closely related;2)The change of network structure in the first 10 years was larger than that in the second 10 years;3)The development of Wenzhou settlements was unbalanced,and the southern bank of Oujiang River was attractive to the surrounding areas and continually grew;4)Terrain and economy were the main influencing factors for the formation of spatial network structure of Wenzhou settlements.Low and flat areas were widely distributed,and the more developed the economy was,the stronger the settlement centrality would be.Finally,it was concluded that the evolution of spatial network structure was closely related to topography,water system,population growth,economic development and urbanization construction.
