摘要
城市土地利用是地理学、土地科学和城市规划等多学科研究的核心领域,随着中国城镇化进程的快速推进,中国城市用地扩张成为近年来该领域关注的焦点问题之一。本文从全国、区域和个案城市3个尺度总结了中国城市用地扩张的特征和空间模式;从LUCC、区域统计和案例剖析3个视角对城市用地扩张及驱动力的既有研究成果进行了梳理、分析和归纳。研究发现,学科的交叉性决定了关于城市用地扩张问题的研究在视角、尺度、方法、数据等方面有明显不同,相关研究的差异和纷争较大;实证研究方法逐渐多元化,但模型建设有待加强,理论研究起步较晚。从现有研究进展来看,应加强学科内和学科间的交流与融合,强化城市土地利用变化的理论研究。
Urban land expansion has received considerable attentions in the recent debates in the studies in geography,environmental science,land science and urban planning.The sustained rapid urban land expansion in China has led to a series of problems and many papers focusing on this issue have been published in recent years.This paper summarizes the characteristics,spatial patterns and its driving forces of urban land expansion at national,regional and urban scales from perspectives of LUCC,regional statistics and case studies.China has been experiencing a rapid urban land expansion with a significant spatial diversity since the 1990s.The rapid growth of urban land is driven mainly by urban population and economic growth,industrialization and national and local policies.As a multidisciplinary science,researches on urban land expansion in different subjects keep separate and distinct from each other in perspective,scale,methods and data.There are abundant approaches for empirical study,while few for model establishment,not to mention the theoretical research.The absence of basic theories and research paradigms leads to the incomparability of researches from different perspectives,which will restrict further studies in this field.At last,the authors argue for intradisciplinary and interdisciplinary communication and integration to improve the theoretical research on urban land expansion.
