港口岸线增长与城市土地利用变化强度关联分析

Analysis of association rules between port coastline growth and urban land use change intensity

为分析海岸线变化与土地利用变化之间的相关性,揭示在港口发展主导下沿海城市扩张过程内在机理,该文提出了利用Apriori关联规则算法对港口城市一定时期内土地利用变化强度的序列模式与岸线变化强度进行关联规则挖掘。分别挖掘出了岸线变化强度与土地利用变化强度、港口距离与土地利用变化强度之间的关联规则。挖掘结果表明:港口岸线变化的强度对朝内陆方向上的土地利用变化强弱次序有着重要影响。该研究揭示了海岸线变化与土地利用变化的内在联系,以及港口发展主导下的城市扩张模式,为合理规划港口城市空间结构提供参考。

In order to analyze the correlation between coastline changes and land use change,and reveal the internal mechanism of urban expansion under the leadership of port development,this paper proposed to use the Apriori algorithm to mine association rules for land use change sequential and port expansion in a certain period of time,and succeeded in mining association rules between coastline change intensity with land use change intensity and association rules between distance from port with land use change intensity.The results showed that the intensity of coastline changes had an important impact on the sequential pattern of land use change in the inland direction.This study revealed the intrinsic relationship between coastline change and land use change,and Urban expansion model led by port development,and provided references for rational planning of port city spatial structure.
