| 摘 要： | 云南是一个地震多发区。１６５２年至１９９４年间云南地区共发生６１３次破坏性地震，其中５．０—５．９级地震５５３次，６．０—６．９级地震４９次，７．０—７．９级地震１２次，８级地震１次。云南的破坏性地震除了直接造成人员伤亡和建（构）筑物破坏外，还在震区形成包括滚石、崩塌、滑坡、泥石流、地面沉陷和喷砂冒水等地面破坏现象，这些地面破坏造成人员伤亡，毁坏建筑物和农田，形成云南破坏性地震灾害特点。云南地区破坏性地震的人员伤亡和地面破坏主要集中发生在滇中、滇西北和滇西南地区。根据统计分析，云南地区破坏性地震的平均人员伤亡人数（Ｎ）与地震震级（Ｍ）的关系为：ｌｇＮ＝１．５Ｍ－７．４。人员伤亡数（Ｎ）与震中距Ｄ（ｋｍ）的关系为：ｌｇＮ＝０．８－０．０２７Ｄ（６．０—６．９级地震）和ｌｇＮ＝３．２－０．０５Ｄ（７级以上地震）。出现地面破坏现象的最大震中距离（Ｄｍａｘ）和震级的关系为：Ｄｍａｘ（ｋｍ）＝５２Ｍ－２９８（地表裂缝）；Ｄｍａｘ（ｋｍ）＝１８Ｍ－９３（崩塌滑坡）；Ｄｍａｘ（ｋｍ）＝５０Ｍ－２８１（滚石）。

| Abstract: | Casualties and ground failure caused by earthquakes are major earthquake disasters in Yunnan, their distribution are of obvious regional feature and mainly concentrated in center,northwestern and southwestern Yunnan. The occurrence and distribution range of the casualties and ground failure in Yunnan are related with magnitude and intensity of earthquakes obviously. |
