| 摘 要： | 信息熵和分形理论为研究地理学中系统的有序性和复杂结构现象的不稳定性提供了一条新途径,为研究土地利用景观格局变化提供了新的思路。以信息熵和分形理论为指导,在遥感和GIS技术支持下,对西安市土地利用景观格局演变的分形特征和信息熵进行分析,结果表明:1999-2008年,西安市土地利用景观结构趋于简单化,景观类型在空间上的稳定性逐渐增大;土地利用景观结构信息熵总体上呈逐渐下降趋势,即土地利用有序度逐渐上升,而无序度逐渐降低。

| Abstract: | Entropy and fractal theory provides a new way for study instability of the system,order and the complex structure phenomenon of in Geography,and it also provides a new idea for researching on the change of Landscape pattern of land use.The paper is based on using entropy and fractal theory as a guide,we analyzed the fractal characteristics and entropy from the landscape patterns in land utilization changes in Xi’an in support of Remote sensing and GIS technology,the result shows that: from the year of 1999 to 2008,the landscape structure of Xi’an land use tends to simplify,Landscape types increases the stability in space,the entropy of landscape structure in Land use decrease gradually overall,that is the degree of order of land use increased gradually,while the degree of disorder decreased. |
