The means, importance and working flow of data mining, information fusion and map repackage are introduced in brief. As we know, among the above three factors, map repackage is most important in our studies, because we may get new information or produce new maps if we repackage multisource maps which are available. As an example of map repackage, in this paper, three digital maps including land use map, soil erosion map and physiognomy map were repackaged by use of overlay to produce a new map of soil erosion...

The means, importance and working flow of data mining, information fusion and map repackage are introduced in brief. As we know, among the above three factors, map repackage is most important in our studies, because we may get new information or produce new maps if we repackage multisource maps which are available. As an example of map repackage, in this paper, three digital maps including land use map, soil erosion map and physiognomy map were repackaged by use of overlay to produce a new map of soil erosion background map. Three steps are involved in compiling soil erosion background map. First, island-like land information is drawn out by mining data from land use map according to the definition of islandlike land. Then the island-like land, which is not influenced by humans, is named the natural island-like land. Second, the erosion background value of natural island-like land is given by overlaying the maps of land use and soil erosion. Since the natural island-like land is the land without being anthropogenically influenced, its soil erosion value is the background value. Finally, soil erosion background value in the entire area will be gotten by overlaying the maps of physiognomy and soil erosion background of natural island-like land. As physiognomy is the most stable and relative basic factor among the factors that influence soil erosion, we suppose that soil erosion value of all land pixels in a kind of physiognomy pixel is a stable value if they are natural. So in this way, the soil erosion background map is worked out by repackaging land use map, soil erosion map and physiognomy map. In the end of the paper, this method was success fully applied in the agro-pastoral ecotone of Inner Mongolia. The success of the model in the ecotone of Inner Mongolia shows that the production of soil erosion background value through repackaging the maps of land use, soil erosion and physiognomy is fessible. Nowadays, with the development of science and technology, more information from multi-sources is easy to be fully used of or be reconstructed through mining, fusion or repackage. In the ecotone of Inner Mongolia, the multi-source information of remote sensing maps or maps compiled based on massive survey makes availability of soil erosion background value. And the more information is used of, the more precision of the result.

对土地利用图进行信息的挖掘,结合岛状地的界定,提取了其中的岛状地信息;与天然性程度的信息源进行融合,得到了天然岛状地信息;再与土壤侵蚀图、地貌图信息重组,最终得到了土壤侵蚀背景值信息,生成土壤侵蚀背景值图。通过在内蒙古农牧交错带内的试验研究,说明基于土地利用图、土壤侵蚀图和地貌图的多源地图信息重组,编制土壤侵蚀背景值图的方法是可行的。
