中国土地利用/覆被重建数据集历史文献数据源的应用现状与前景

Review and prospect on historical literature data sources of China’s land use and land cover reconstruction dataset

历史时期土地利用/覆被变化(LUCC)是全球变化研究的重要组成部分。中国丰富的历史文献资料是开展长时段LUCC数据集重建的关键数据源。从百年以上历史文献数据源应用的角度分析现有中国LUCC重建数据集,将历史文献中蕴含的土地利用数据源归纳为统计、列举、描述和图像4种主要类型,从各类数据源应用现状、制备方法等方面对现有重建数据集进行了重点回顾,归纳重建数据集应用历史文献的主要特点和存在问题,并从多重历史数据源综合利用、重建思路调整、利用现代信息技术提高数据源制备效率等方面展望了LUCC重建数据集改进历史文献应用方式、方法的未来发展趋势。

Land use/cover change(LUCC)in historical period is an important part of global change research.For historical LUCC over a period of more than 100 years,due to the lack of direct data with clear spatial attributes,the main way to explore this problem is to collect various proxy data and combine geographic modeling to reconstruct the spatial pattern of historical LUCC on the basis of in-depth understanding of the past spatio-temporal evolution process of land use/cover.China’s rich historical literature is the key data source for the reconstruction of long-term LUCC data sets.Continuously mining,compiling,and updating historical data sources from the literature is the basis for the continuous advancement of research.This paper analyzes the existing LUCC reconstruction data set in China from the perspective of the application of historical literature data sources.The land use data sources contained in the historical literature are summarized into 4 main types:Statistics,enumeration,description and image.Historical statistics combined with modern impact factors,historical statistics combined with enumerated data,historical data sources based on descriptions,and historical data sources based on images are the main methods for reconstructing LUCC datasets using historical data sources.The recovery and revision of statistical data,the spatialization of enumeration and description data,and the precipitation of image data are the main means for the preparation of historical data sources.The current reconstruction data set is reviewed from the application status of various data sources,data preparation methods and other aspects,and the main characteristics and problems of the reconstruction research application of historical literature are summarized,The future development trend of LUCC reconstruction historical literature application and historical data source preparation is prospected from the aspects of comprehensive utilization of multiple historical data sources,adjustment of reconstruction ideas,and use of modern information technology to improve data preparation efficiency.
