南水北调中线工程水源区土地利用类型分形研究

分形理论为开放复杂的地学系统在时间序列上进行分形特征的研究、预测提供了可能.运用分形理论,对南水北调中线工程水源区土地利用类型的分布结构分析表明:研究区的土地利用类型具有分形结构,其中耕地、居民用地、林地的分维值偏离随机值较大,土地利用状态相对稳定,比较接近规则体;布局复杂且不稳定的水体偏离随机值较小.对比南水北调中线...

A Fractal Investigation into the Land Use Type of Water Resources Area in South-to-North Water Diversion Central Line Project

The fractal theory makes it possible to study or predict the open and complicated geographic system in time order by fractal characteristics.The article analyzes the distribution structure of land use type in south-to-north water diversion central line project by using fractal theory.It demonstrates that the land use type in the research area has fractal structure,in which the fractal dimension of cultivated land,residential land and timberland diverged dramatically from random value.The land use condition is relatively stable and close to regular state.The complicated and instable water-body shows a slight divergence from random value.The comparative study of the present situation of land use type in south-to-north water diversion central line project finds a new reference to evaluate whether the land use type is scientific and reasonable by using fractal theory.
