摘要
LUCC信息学方法体系是集区域自然地理学理论方法与GIS技术于一体的新兴学科领域。该方法体系以遥感、GIS及海量数据采集与处理技术为基础,主要应用于多尺度、多层次的土地利用和土地覆被变化时空过程与格局演替探测与模拟、驱动机理提炼及宏观生态效应分析研究,并在相关专题的案例研究中,得到不断验证、丰富与发展。本文回顾了LUCC信息学方法体系的发展历程,阐明了我国LUCC信息学方法体系的核心方法、技术特征和研究现状。其中,土地利用与土地覆被遥感动态信息提取与分析、驱动机理提炼、时空过程模拟、宏观生态效应评价技术的发展和土地利用与土地覆被研究信息平台的建设及相关技术方法的集成,推动了中国LUCC信息学的形成,并构成了LUCC信息学方法体系的基本结构。
Abstraet：LUCC informatics system, LUCCIS, is a newly developed research field on the basis of integrating the classical methodology of physical geography and the new progresses in GIS technologies. As a research field focused on studies of temporal and spatial processes of LUCC, LUCCIS has developed rapidly in past decades in which some technical components have been improved greatly. LUCCIS focuses on material cycles and macro life processes of multiple scales on the land surface with supports from remote sensing, GIS, and data fusion technologies. In this pa- per, the progresses of those kernel methodologies, techniques as well as compositional research achievements in Chi- na are described in detail, which make it possible for the establishment of LUCCIS. Specifically, the development in the technologies of extraction and analyses of remote sensing information, the exploration of driving mechanism of LUCC over space and time dimensions, the simulation of the spatial-temporal process and pattern of LUCC, the e- valuation of the macro-ecological effects of LUCC and the establishment of research information platform of LUCCIS are all promoting the development of LUCC studies in China. The domestic research trends indicates that the development of extraction and analytical technologies of remote sensing information, the case study of exploring driving mechanism of LUCC, the methodological innovation of simulating the temporal and spatial process of LUCC, and the more accurate description of macro-ecological effects of LUCC play important roles in the methodology framework of LUCCIS. Also, the construction of multi-source and temporal-spatial data platform and the realization of massive da- ta availability and integration are all kernel components of the methodology framework of LUCCIS. We can expect that LUCCIS would play a more and more important role in promoting LUCC research activities at regional and global scales.
