城市化在促进区域经济和社会发展的同时也导致产生一系列景观生态安全恶化问题,严重威胁区域可持续发展。定量分析城市扩张与景观生态安全之间的关联规律对于城市可持续发展至关重要。本文以武汉市为例,利用关联规则挖掘模型挖掘1988~2011年时间范围内武汉市城市扩张的速度、强度以及扩张类型与景观生态安全之间的关联知识,可以为城市规划提供有益指导。
As urbanization promotes regional economic and social development, it also leads to a series of deterioration of landscape ecological security and a serious threat to regional sustainable development. Quantitative analysis of the relationship between urban expansion and landscape ecological security is crucial for sustainable urban development. Taking Wuhan as an example, this paper uses the association rule mining model to mine the speed and intensity of urban expansion in Wuhan in 1988 ~ 2011, as well as the related knowledge between expansion types and landscape ecological security, which can provide useful guidance for urban planning.
