This thesis intends to investigate the ants' faunas of Mt. Hwangryeong located in downtown Pusan. For this purpose, samples were collected twelve times in total, four times for the three different slopes(north-east, south and north-west) respectively from May 2002 through September 2002. In addition, samples were classified three different levels(upper, middle and bottom) in term of vertical altitudes according to each relevant slopes. The observation and classification of 1176 colonies collected form the different slopes of the mountain are as following; 1. It turns out that 4 families, 17 genus and 26 species in the north-east slope, 4 families, 14 genus and 18species in the southern slope and 4 families, 17 genus and 28 species in the north-west slop are being distributed so that three are 4 families, 19 genus and 33 species in total throughout the mountain, and Tetramorium caespitun as a dominant is relatively abundant up to 27.9 percent. Ants belonging to the family of MYRMICINAE are distributed in the highest density of 10 genus and 15 species. Because of the mountains' in-land geographical features, the ants of FORMICINAE family are distributed in a relatively high density with 4 genus and 13 species. 2. From the perspective of vertical distribution to the altitudes of the mountains, there are 19 genus and 33 species. among them 15 genus and 19 species in the bottom level(70m-219m), 8 genus and 11 species in the middle level(220m-319m) and relatively abundant 15 genus and 23 species in the upper level(320m-428m). 3. The fact that Tertamnrium bicarinatum was found both in the southern and north-west slopes of the mountains was identified as the ant living in Korea. Besides both Camponotus herculeanus sachalinensis and Aphaenogaster famelica which were not collected in the Kyungnam province are found in north-east slope of Mt. Hwangryeong. 4. An analysis on the community's structures with respect to the different slopes shows that diversity index is the highest in the north-east slope, richness index is the highest in the north-east slope and dominant index is the highest in the southern slope, while the similarity index is equally the highest in the both in the north-east and southern slopes.
