基于转移矩阵的兰州市商业用地质量演变分析

摘要

Markov chain in land type conversion tendency model has been used in evolution analysis of city land quality.Through the establishment of land quality grade transfer matrix,setting quality level changes of commercial using land in Lanzhou city from 2009 to 2014 as the application case,the effect of land quality transfer matrix to land use in cities has been studied.It is showed that the construction of the transfer matrix can reflect the tendency evolution of land quality level effectively.And it can predict the future trend of city land quality in a certain extent.Further,it is the driving force of studying the evolution of land quality in the city,and can guide and promote land resources utilization in the future.%将地类转换倾向性模型中的马尔可夫链引入城市用地质量演变分析中,通过建立土地质量等级转移矩阵,以兰州中心城区商业用地2009-2014年质量等级变化为应用案例,探讨土地质量转移矩阵对城市用地质量演化的影响.研究表明,转移矩阵的构建能够有效的反映城市用地质量等级演变倾向,在一定程度上预测未来城市土地质量的演变趋势,探寻城市用地质量演变的驱动力,有利于指导和促进城市未来土地资源的高效合理利用.
