摘　　要：首先根据我国矿区土地复垦工作中存在的不足,通过研究提出"动态土地复垦"的概念,并确定了动态土地复垦方案制定的数据基础——动态矿区数字高程模型。动态矿区数字高程模型应该包含煤矿生产对地表的累积影响结果数据和地表的原始地形信息,开采沉陷预计结果可以提供前者,地面测量可以提供后者,经过数据处理可以按时间间隔生成描述塌陷区的一系列数字高程模型(DEM)(准动态),然后运用DEM的空间分析技术提取塌陷区在不同时间段的土地破坏类型、范围和位置数据,并根据这些数据进行动态土地复垦方案决策数据的提取,经实例验证该方法可行。Firstly, according to the insufficiency existed in the work of mining area land reclamation in our country, the conception about ＇dynamic land reclamation＇ was distilled and the data foundation dynamic digital mining area digital elevation model （DDMDEM） which was used to define dynamic land reclamation approach was also determined. DDMDEM should include the accumulated effect result data of land surface caused by coal mining production and the original terrain information of land surface. The former one can be supplied by mining subsidence result data, while the latter one can supplied by field surveying, According to time interval, a series of digital elevation models （DEM） （quasi -dynamic） used to describe subsidence area can be generated by data processing, then spatial analysis technique of DEM was used to distill land damage types, range and position data in subsidence area at different periods. Research on dynamic land reclamation scheme was done according to these data and the result from practical instances demonstrated the feasibility of this method.
