Risk assessment maps were categorized into four levels,including"low","moderate","high"and"very high".These results show that some urban areas are at very high risk,including Jiegu,Chengwen,Xiaxiula and Sahuteng towns.This research can provide some references and suggestions to improve decisionmaking support for emergency relief and post- earthquake reconstruction in the study area.展开更多

It uses the mathematics statistics knowledge and management knowledge to establish a scientific and operable performance evaluation model for the industrial structure adjustment of the industrial enterprises. Based on the model, it can make a performance evaluation for the internal industrial structure adjustment of the industrial enterprises and also it can evaluate the performance of the industrial structure adjustu^ent of different industries.展开更多
