基于遥感的城市边缘区土地利用动态监测

DYNAMIC MONITORING ABOUT LAND USE IN THE URBAN FRINGE AREA BASED ON THE REMOTE SENSE

城市边缘区在城市地域结构体系中处于城市与乡村的过渡地带 ,从而既属于生态环境脆弱带 ,又属于城市区域人文因素高度复合带 ,其时空特征表现出十分迅速和不稳定的特征。及时了解和掌握城市边缘区土地利用变化的状况 ,对于合理进行城市规划 ,调整用地结构 ,实现区域可持续发展具有十分重要的意义。本文以LandsatTM为基本信息源 ,以Coreldraw和ARC/INFO为主要支撑软件 ,完成了实验区从1987年到 1996年的城市边缘区土地利用动态监测与分析。此技术路线能够有效地提取城市边缘区土地利用动态信息 ,工作周期短 ,误差积累少 。

In the structure of urban area, urban fringe lies in transitional region between urban and rural. It is the fragile area of environment and also the joint area of human factors, and shows the rapid and unsteady charactors in different time and space. Finding out the changing situation of urban marginal regions land use timely will be benificial to the urban plannings relization, landuse structures readjustment and sustainable developments realization. Taking land sat TM as basic information resource and Coreldraw and ARC/INFO as main supporting software, this paper achieves the dynamic monitoring and analysis of urban fringe land use from 1987 to 1996 in the experiment area. At the same time, this technical ways can be used to take informations of urban marginal regions land use effectively according to its short worktime, few error accumulation and high rate of determination and location.
