区域发展与土地利用空间分异关系的实证研究

Empirical Study on Relationship between Spatial Differentiation of Land Use and Regional Development

该文选取潍坊市为研究区,通过主成分分析和聚类分析等方法,构建区域发展评价模型,并运用景观空间格局分析方法总结土地利用空间分异规律,最后采用相关性分析方法探讨二者关系。研究得出:区域发展与景观格局指数中的景观斑块密度和分维数相关性较强。区域发展与土地利用空间格局变化息息相关,土地利用景观的斑块密度和分维数,能够较好反映区域发展阶段的特征状态。

The purpose of this paper is to verify the relationship between regional development and spatial differentiation of land use,by analyzing unbalanced development area.Weifang city was taken as a study area in the project,this paper constructed an evaluating model by principle components analysis and cluster analysis methods,summarize rules of spatial differentiation of land use by applying landscape patterns analysis method,studied that relationship by adopting correlation analysis method finally.The results explained that patch density(PD)and landscape fractal dimension(PAFRAC)had a strong correlation with regional development.It was concluded that regional development was closely linked with spatial pattern changes of land use,which could be reflected by PD and PAFRAC well.
