云南山地地震地质灾害对河流综合开发的影响

摘要

The geological tectonic background, seismicity and seismicdisasters in Yunnan's rivers have been described. The seismogeological condition for the major branches has also been analyzed. 83.3% of areas of runoff for the river is located in intensity Ⅶ and above. Most of the sites of 200 hydropower stations are located in intensity Ⅶ or above. Some suggestions for reducing seismogeological disasters in sustainable development of river have been put forward.%概述了云南河流的地质构造背景、地震活动及其震害一般特征；分析了云南河流主要干支流的地震地质环境，云南的河流径流面积的83.3％处在Ⅶ度及以上地震烈度区，已勘测出的近200处河流干支流水电站站址的绝大多数处在Ⅶ度及以上地震烈度设防区；对云南河流综合开发可持续发展中减轻地震地质灾害的工作提出了几点建议。
