Abstract: Through analyzing the influencing factors of biological repair area,according to the spatio-temporal features of occurrence and distribution of soil and water loss,combining the features of HBDS,USLE equation and link mechanism,applying GIS technology,we reasoned the spatio-temporal rule of ecological rehabilitation,and then constructed a hyper-graph spatio-temporal reasoning model based on moving objects.After applying this model in the system of ecological rehabilitation,we realized the effective monitoring,management and prevention and acquired the anticipative effect.

摘要：

通过对生态环境修复过程中对各种影响因素的分析,根据水土流失的发生和分布的时空特性,结合超图数据结构的运算特点、USLE方程以及连接机制,利用GIS技术,对生态环境修复的时空变化规律进行了推理,建立了基于移动对象的超图时空推理模型,通过该模型在生态环境修复系统中的应用,可以对水土流失进行有效的监测、管理和防治,取得了良好的应用效果。
