ABSTRACT
The so-called differences refer to the structural, temporal and spatial differences in various key elements, multiple layers and several functions within the entire system (Wu, J., 1991.). As a specific subject of the geographic and spatial data, the differences among the multi-temporal land use status data sets can be analyzed and described on the basis of differential theory for geographically spatial data. Currently, investigators have not yet formed the uniform understanding and recognition on the issues of differences in geographical and spatial data sets and different investigators proposed different classification systems with various details according to different research problems and different research angels (Cui, T.J. and Guo, L., 2007; Wang, Y.H., 2011.). For the understanding convenience, in this study, based on the investigation and analysis, the
1 INTRODUCTION
Land is the material basis for the survival and development of human beings. To conduct dynamic survey and monitoring on the status of the locations, areas, types, ownership/obligation, and arrangement of land use in different periods of time by using the topographical, remote sensing and Geographic Information System (GIS) techniques and to conduct comprehensive analyses on these data are one of the core tasks for the land administration departments of various countries in the world. Since the implementation of reform and open policy, our country (China) has conducted one after another two national-wide “Land Use Change Survey and Data Update”. However, due to the differences in the background characteristic of times, legal basis, classification systems, technical criteria, and operational specification between two surveys (Zhang, Y.Q. and Yang, Z.S., 2013.), there have been various differences existing in the collected data sets for the multi-dynamic land use status, which, in turn, limit the comprehensive analysis, assessment, prediction and application of these multi-temporal land use status data.
