摘 要:本文论述了我国地震活动特点和工业企业分布的关系。①我国大陆地震及工业分布以东经104°(南段)—106°(北段)为界,西部地震活动强度大、频次高,工业发展相对落后;东部地震活动水平低,但工业发达。②不同的地震区(带),工业分布格局不同,华北地震区以钢铁、石化和煤炭等重工业为主;华南地震区以加工工业为主;南北地震带以原材料工业为主。This paper discusses the relation between characteristics of seisndcity and the distribution of industrial enterPrises in China. 1. The boundary between earthquakes of the Chinese mainland and industrial distribution is the line 104° (south ) - 106°E (north). To the west of this line, the level of seismicity is strong in intensity and is high in frequency, where the industrial development is relatively backward; while to the east of this line, the level of seismicity is low, and there are developed industries. 2. There are different industrial structures within different seismic zones. Heavy industries, shch as iron and steel, petrochemicals, and coal are taken as the dominant factor in the North China seismic zonei processing industry is taken as the key industry in the South China seismic zonel raw and sendfinished materfals industries play a leading role in the North-South seismic zone.
