다국어 초록 (Multilingual Abstract)

This experiment was conducted on the ecology of field mice of Mt. Geumjung in Pusan for four time from December, 1995, to September, 1996, in order to protect forest injury of field mice.
The result are obtained as follows ;
1. The species of field mice collected were Apodemus agrarius coreae, Apodemus speciosus peninsulae and Crociadura suaveolens shantungensis of insectvore and Rattus norvegicus of house mice.
2. The total collecting rate were 8.4% collected 55 individuals of field mice from 653 traps.
3. The rate among the 55 field mice collected were 56.4% in Apodemus agrarius coreae, 36.4% in Apodemus speciosus peninsulae, 5.4% Crociadura suaveolens shantungensis and 1.8% in Rattus norvegicus
4. The ratio of female to male of field mice was 40.0 : 60.0 in Apodemus agrarius coreae, 52.6 : 47.4 in Apodemus speciosus peninsulae, 66.7 : 33.3 in Crocidura suaveolens shantungensis and 0 : 100 in Rattus norvegicus
5. The constitution of weight of field mice was 14.0∼45.9g in Apodemus agrarius coreae, 16.0~39,9g in Apodemus speciosus peninsulae, 4.0~15.9g in Crociadura suaveolens shantungensis in Rattus norvegicus
6. the average body length was 94.31mm in Apodemus agrarius coreae, 97.42mm Apodemus speciosus peninsulae, 67.67mm in Crociadura suaveolens shantungensis and 205mm in Rattus norvegicus.
7. The average tail length was 79.28mm in Apodemus agrarius coreae, 98.21mm in Apodemus speciosus peninsulae, 39.33mm in Crociadura suaveolens shantungensis and 162mm in Rattus norvegicus
8. The breeding period of field mice presumes from about the end of March to early in October and fetal number was 4.0 in crocidura suaveolens shantungensis.
