The purpose of this paper is to explore the spatial-temporal characteristics of spatial balance degrees on land use in China and provide reference for deeply understanding the law of spatial balanced development on land use and strengthening the scientific control of land use.The methods used in this study include the index model and markov chain.The results show that:1)the overall land use spatial balance degree shows a steady fluctuation in China,and the degree difference among provinces is narrowing.In addition,the phase change is mainly featured as the decrease of spatial balance degrees on land use.2)The spatial distribution of spatial balance degree on land use is imbalanced in China.In addition,the spatial balance degrees on land use have significant regional differences,that is,the degrees of eastern and central regions are high,while the degree of the western region is low.The evolution process is from centralization to decentralization in space.3)The order of stability among the four types of states of land use spatial balance degree is high quality balance,moderately balance,barely balance and imbalance.In conclusion,the change of spatial balance degrees on land use depend on the change of the values of regional land development size as well as the intensity divided by regional actual land supply capacity,which contributes to the evolution of distribution pattern of spatial balance degrees on land use.%研究目的:探究中国土地利用空间均衡度时空分异格局和动态变化,为深入理解土地利用空间均衡发展规律,加强土地利用科学管控提供参考.研究方法:指数模型,马尔科夫链.研究结果:(1)中国土地利用空间均衡度总体呈平稳波动,省份间土地利用空间均衡度差异逐渐缩小,阶段性变化以土地利用空间均衡度下降为主要特征;(2)中国土地利用空间均衡度空间分布不平衡,且地区差异显著,具有东、中部地区高,西部地区低的特征,土地利用空间均衡度在空间上整体表现出从集中到“分散化集中”的演变过程;(3)土地利用空间均衡度的4种状态中,优质均衡的稳定性强,中度均衡次之,勉强均衡和失衡状态的稳定性较弱.研究结论:土地利用强度和区域土地供给能力的相对关系变化会引起土地利用空间均衡度的变动,进而推动土地利用空间均衡度分布格局的演变.
