| 摘 要： | 以闽台为研究区域,以统计数据为原始数据,绘制闽台耕地数量变化过程线,运用ArcGIS计算得到两者的计盒维数。结果表明:(1)闽台耕地数量变化过程线的栅格单元边长与栅格数目在双对数坐标下呈显著线性分布,体现出明显分形特征;(2)福建耕地数量变化过程线的计盒维数为1.027,台湾为1.004,表明福建耕地数量变化过程更复杂,福建耕地数量变化过程线的峰谷变化幅度大于台湾,而峰谷变化频度小于台湾;(3)采用计盒维数结合传统指标,对耕地数量变化过程的评价会更全面、科学,但分形维数的应用还存在诸多难题。

| Abstract: | Taking Fujian and Taiwan as the researched areas,this paper used statistical data as the input data for obtaining vectormaps of cultivated land change.ArcGIS was used to calculate the box-counting dimensions of cultivated land change curves.The results indicated that:(1) The side length of the box showed a significant linear correlation with the number of corresponding box,which demonstrated that the cultivated land change curves had obvious fractal characteristics in Fujian and Taiwan.(2) The fractal dimen... |
