摘要: 运用改进的土地利用变化强度分析框架探析国家中心城市土地利用变化模式的稳定性和系统性特征。以土地利用变化转移矩阵为基础,从自上而下的三个层次(间隔、类别、转换)分析区域土地利用变化强度动态特征。鉴于多种地类相互转换过程分析的非直观性,提出一种转换模式交叉列联表表示各种转换类型的稳定性和系统性特征,并有助于研究者将土地利用变化的模式与过程相联系。以国家中心城市武汉为研究案例,分析其1996—2015年土地利用变化模式的稳定性和系统性特征,并对比其他国家中心城市近年来土地利用变化模式特征。结果表明:武汉市近年来土地利用变化强度呈上升趋势,农村居民点用地、城镇建设用地和耕地的转入以及耕地、未利用地和水体的转出表现出时间尺度稳定性。耕地向城镇建设用地和农村居民点用地等转换过程则表现为稳定的系统性变化模式。其他国家中心城市主要土地利用变化模式与过程及武汉市表现出较大的相似性。改进后的强度分析框架能更直观地反映土地利用变化模式的稳定性和系统性特征,研究结果对深入挖掘国家中心城市土地利用变化模式信息,理解其土地利用变化过程与机制具有重要作用。

Abstract: We revised the intensity analysis framework proposed by Aldwaik and then applied it to examine the temporal stationary and systematic characteristics of land use and land cover change (LULCC) patterns in the national central cities of China. This hierarchical framework analyzes LULCC at three levels: time interval, category, and transition, based on land use change confusion matrices. Given the inconvenience of transition level intensity analysis in presenting the detailed pattern of LULCC across multiple time intervals, we put forward a new method termed as land transition pattern confusion table to systematically show all the land conversion processes in one figure so as to help link LULCC process to pattern and clarify their driving mechanisms from a bottom-up perspective. Taking Wuhan City as a case study area, this article analyzes the stationary and systematic characteristics of LULCC patterns from 1996 to 2015 with the improved framework. Also, LULCC patterns in other national central cities in recent years were investigated. The results show that the overall LULCC intensity in Wuhan City increased in recent years. The influx of rural residential land, urban construction land, and farmland intensified. The efflux of farmland, water, and unused land grew as well. Notably, the transition from farmland to urban construction land and to rural residential land is characterized by a stable and systematic change pattern. The LULCC patterns and processes in different national central cities show great similarity. This improved intensity analysis framework can be more intuitive in reflecting the stationary and systemic characteristics of LULCC pattern. The research results can play an important role in illustrating LULCC patterns in the national central cities and facilitate linking processes and mechanisms to these observed patterns.
