| 摘 要： | 结合前人资料的系统梳理、遥感解译及地表调查结果,对滇中城市群地区的活动断裂进行活动程度分级,得到该区"5纵2横"13条主要活动断裂的构造体系分布格局。按断裂活动强弱程度对城镇及重要工程的影响不同,对滇中城市群地区城镇和"十三五"及中长期规划的重大工程开展活动断裂影响调查研究,表明活动断裂是影响和制约该区城镇规划及重大工程建设的主要地质因素。综合考虑活动断裂活动程度、岩性特征和地形变化3因素进行的区域地壳稳定性评价初步结果表明,该区的"极不稳定区"、"不稳定区"和"次不稳定区"约占全区面积三分之一。

| Abstract: | Combining previous data, active fault remote sensing interpretation and geological field survey, we classify the active faults into four classes according the fault activity in city group of central Yunan. They are faults with very high activity rate, faults with high activity rate, faults with moderate activity rate and faults with low activity rate. It shows that there are thirteen main active faults zone in the study area, with an image of "5 longitudinal and 2 lateral" fault zones. The study of the active fault affection on the main project reveals that the active faults are the key geological factor that restricts the layout of the cities and the main projects. The regional crustal stability assessment is calculated by the three factors of faults, rocks and slopes. The result suggests that most areas of the city group of central Yunnan is "unstable",one-third of the city group area is "extremely unstable region", "unstable region" or "sub unstable region". |
