Carabus beetles were studied in the plantation (5, 25 and 40 years old) and natural forest (5-8, 20-30, 35-45 and 60-80 years old) of Larix principis-rupprechtii in Pangquangou National Nature Reserve（111°22′-111°33′E，37°45′-37°55′N）, Shanxi, China from May to September in 2006 and 2007. Pitfall trapping was employed in the study. Specimens of 1290 beetles were collected and identified as 10 species of Carabus, of which 9 species were new distribution records in the Reserve. Of the collected specimens, C. canaliculatus, C. crassesculptus, C. manifestus and C. vladimirskyi accounted for 29.4%, 28.4%, 17.3% and 13.9%, respectively. These four species were the most abundant species in the research area. C. hummeli, C. sculptipennis and C. granulatu each accounted for 5%-1% of the total specimens, and were common species in the study area. C. tuberculosus made up 0.9%, C. sui and C. anchocephalus 0.2% of the total, and they were rare species in the area.
