摘要 基于遥感影像和地理信息技术，利用 1980 年上海土地利用分类数据为底图，选取 1987 年、1993 年、1999 年、2010 年 4 个时相的上海市遥感影像，采用监督分类及目视解译法，探讨 1980 — 2010 年上海土地开发利用的时空变化。研究发现，上海土地开发利用变化与城市经济发展的周期关系密切，不同时期上海土地开发利用变化的区域空间是不均衡的，总体上表现为“东多西少、南密北疏” 的特点。在时间上，20 世纪 80 年代土地开发利用变化主要发生在中心城区；90年代后逐渐扩展到近郊区，且主要集中在浦东新区；进入 21 世纪，土地开发利用变化已经转移到远郊区的各个新城。在空间上，上海土地开发利用变化的郊区化倾向明显，距离衰减效应显著。

Abstract Based on the categorical data of Shanghai land use in 1980, this study analyses a selection of four remote sensing images of Shanghai city in four different time phases, i.e., 1987, 1993, 1999 and 2010, by means of supervised classification and visual interpretation. In doing so, it aims to explore the temporal and spatial changes of Shanghai land use from 1980 to 2010 using remote sensing image and Geographic Information System technology. The research indicates a strong relevance of the changes in Shanghai land use to the cycles of urban economic development. In different time phases, changes of land use in Shanghai city is found to be regionally and spatially uneven, with the east of the city more drastic than its west, and the south more intense than the north. As a temporal analysis shows, in 1980s changes of land use take place predominantly in the city’s central area, which gradually expands to its outskirts and significantly Pudong New Area. Up to 21st century, land use changes have shifted to the new towns in the far suburbs. A spatial analysis shows an evident trend of the land use changes shifting to the suburbs, as well as a prominent effect of distance decay.
