【摘要】 对运河遗产进行判别与登录,是大运河遗产保护的基础性工作。对运河遗产基本特征与演变规律的揭示,则是深入认识运河遗产的根本要求。历史舆图直观地反映了古代运河及其沿河的自然环境与人文景观,对研究各历史时期的运河具有重要的参考价值。但由于历史时代的限制,历史舆图在表达位置、距离、形状等地理空间要素时准确性较差,给大运河遗产的判别工作带来了困难。历史舆图与现代空间信息技术结合是解决这一问题的重要途径。通过"舆图新绘"的方式对区域时空演变过程进行复原,从而直观地揭示出运河遗产的本质特征与演变规律,为运河遗产判别提供依据。并且,同步集成的历史地理信息与现状遗存信息数据库也为运河遗产的评估、保护与管理等后续工作提供了坚实的工作平台与数据基础。更多还原

【Abstract】 The identification and registration of Grand Canal heritages is the basis of the protection of all these heritages,while revealing the basic features and evolution laws is the fundamental requirement of further understanding of them.Historic map which directly reflects the natural environment and cultural landscape of this ancient canal is expected as an important reference for studying the canal in different historical periods.But for the limitation of the ancient times,the historic map has poor accuracy when plotting the geo-spatial elements like location,distance,shape etc.,which brings out difficulties for the identification of Grand Canal heritages. Therefore,this study attempts to provide a solution combining the historic map and the modern spatial information technologies by a new approach called "replotting the historic map",which depicts the regional spatial evolution process of the heritages,and thus intuitively reveals the natural features and the laws of evolution of Grand Canal heritages,in order to provide a basis for their identification.In addition,simultaneously integrated database for both historic and present information can also provide a solid platform and data base for subsequent work,such as heritage assessment,protection and management.更多还原
