| 摘 要： | 在土地利用变化及相关研究中,地形图已成为重要的信息源。本文以1∶100000地形图为基础信息源,根据地图制图原理并结合专家知识与规则,进行了没有影像时期的土地利用信息提取的尝试。并选取典型区,以系列影像数据作为背景数据,以耕地为例,将提取结果与同期统计数据及所推算的影像数据进行了对比分析和精度的验证。如以推算的影像数据为标准,则验证误差<5%。研究表明,按照一定的知识规则,基于地形图进行历史时期土地利用信息重建是可行的,完全可以满足相同比例尺及较小比例尺上土地利用制图及分析的需要。

| Abstract: | It is known that land-use and land-cover changes paly an essential role in environmental and ecological changes and furthermore contribute to global change.To understand how land use/cover change affects and interacts with earth systems,information is needed on what changes occur,where and when they occur.Despite ongoing research efforts on land-use and landcover patterns,there remains a need for developing basic land-cover datasets to provide quantitative,spatial land-cover information.In terms of land use and related researches,topographical maps have been the important information sources.Based on topographical maps,integrated with graphics method and expert experience,we tried to extract the land use information without the image.In a typical study area,taking the arable land information extraction as sample,precision was tested and the error was less than 5%,which was compared with statistic data and image data.The result showed that rebuilding the land information based on topography is feasible,which can meet the need of cartography and analyze land use on the same or small scale. |
