珠江三角洲区域稳定性分区评价──引入灰色系统理论

Zoning Evaluation on Regional Stability of the Pearl River Delta by Using the Grey System Theory

将灰色聚类理论应用于珠江三角洲区域稳定性分区评价，建立了灰色系统数学模型．定量分区评价考虑了介质结构、活动断裂、地震、工程地质等因素，共７个指标，采用模型运算，将本区划分为稳定、基本稳定及次不稳定３个区和８个亚区．控制区域稳定性的主要因素是断裂的活动性和断块运动的差异性．

Grey system theory has been firstly applied to the zoning evaluation on regional stability of the Pearl River Delta, and a mathematical model of grey system has been established in this paper. Seven indexes, including basement structures, active faults, seismicity, engineering geology, etc, have been taken into account in the model calculation. This region has been divided into stable, basic stable and secondly unstable and eight subzones. It is believed that the dominant factors controling the regional stability of The Pearl River Delta are the activity of faults and the differnces among block- faultings.
