中文摘要：

进入21世纪，我国城市逐渐迈入城市空间优化、重组的阶段。其中，工业用地置换是城市空间重构与优化的重要过程之一，长期受到城市经济学、城市地理学、城市规划学等学者的关注，是城市研究的重点主题之一。工业用地的置换包括工业用地的转入和转出，因此研究工业用地转入与转出的时空演变特征可以更加深入地了解工业用地置换的过程；转移矩阵方法可以获取工业用地转入与转出的数量与空间分布，从而得到工业用地置换的数量与空间分布，圈层分析和等扇分析可以直观地反映工业用地转入与转出的圈层和方住特征。以长春市中心城区为例，借助ArcGIS软件，利用转移矩阵、圈层和扇形分析方法，深入分析工业用地转入、转出与置换的数量变化特征和空间演变特征，不仅可以了解长春市中心城区工业用地置换的总体特征，还可以了解工业用地置换背后的转入与转出特征，从而更加深入、全面地了解工业用地的置换过程。一方面，丰富城市空间研究的理论成果；另一方面，为工业用地的布局提供一定的理论支撑。

英文摘要：

Since the 21st Century, Chinese cities have gradually entered the stage of urbanspatial optimization and reorganization. Among them, industrial land replacement is one ofthe important processes of urban spatial reconstruction and optimization. It has long beenconcerned by the scholars of urban economics, urban geography and urban planning, and isone of the key themes of urban studies. The replacement of industrial land includes theroll-in and roll-out of industrial land, so study on the spatial and temporal evolution charac-teristics of industrial land roll-in and roll-out can be more in-depth understanding theprocessand spand spnalysisofatlaatiacanindustrial land replacement. The transfer matrix method can obtain the quantitydistribution of industrial land roll-in and roll-out, and then obtain the quantitydistribution of industrial land replacement. Meanwhile, circle analysis and fan a- intuitively reflect the concentric and directional features of industrial land roll-inand roll-out. Taking the central city of Changchun as an example, this paper analyzes thequantitative change characteristics and spatial evolution characteristics of industrial land roll-in, roll-out and replacement by using transfer matrix, circle analysis and fan analysis meth-od, with the help of ArcGIS software. We can not only understand the general characteris-tics of industrial replacement of the central city of Changchun, but also can understand theroll-in and roll-out characteristics behind industrial land replacement. So that we can deeplyand comprehensive understanding the replacement process of industrial land. On the onehand, it enriches the theoretical achievements of urban sppatial research on the other hand,it provides some theoretical support for the layout of industrial land.
