This paper took Mentougou district as an example to analyze ecological restoration functional regionalization, built the index system. Methodologically supported by GIS, this paper carried out the ecological restoration functional regionalization in coal mining areas of Mentougou. All the study area is partitioned to three areas: ecological restoration area, ecological maintenance area and ecological conservation area, and the restoration means and orientations of these three areas are confirmed. Then the result offered a very useful tutor to ecological agricultural restoration engineering in Mentougou district.
