다국어 초록 (Multilingual Abstract)

This study was conducted four ecological survey of field mice of the Children's Grand Park in Busan Metropolitan city from June, 2002, to March, 2003 for the understanding of field mice damage to forest.
The results are obtained as follows.
1. The species of field mice collected were Apodemus agraius coreae, Apodemus speciosus peninsulae and Clethrionomys rufocanus regulus and Crocidura suaveolens shantungensis of insectvore.
2. The total collecting rate were 3.6% collected 43 individuals of field mice from 1191 trap.
3. The rate among the 43 field mice collected were 76.7% in Apodemus speciosus peninsulae. 11.6%in Clethrionomys rufocanus regulus, 7.0% in Crocidura suaveolens shantungensis and 4.7% in Apodemus agraius coreae.
4. The constitution of weight of field mice was 30-35g in Apodemus agraius coreae, 18-45.9g in Apodemus speciosus peninsulae. 22-43.9g in Clethrionomys rufocanus regulus and 5-6g in Crocidura suaveolens shantungensis.
5. The ratio of male to female of field mice was 50% : 50% in Apodemus agraius coreae, 45.5% :
54.5% in Apodemus speciosus peninsulae. 60% : 40% in Clethr-ionomys rufocanus regulus and33.3% : 66.7% in Crocidura suaveolens shantungensis.
6. The average body lengh was 105.2mm in Clethrionomys rufocanus regulus. 100.5mm in Apodemus agraius coreae, 97.42mm in Apodemus speciosus peninsulae and 59.0mm in Crocidura suaveolens shantungensis.
7. The average tail lengh was 95.64mm in Apodemus speciosus peninsulae, 83.5mm in Apodemus agraius coreae, 41.0mm in Crocidura suaveolens shantungensis and 38.6mm in Clethrionomys rufocanus regulus.
8. The breeding period of field mice in the children's grand park presumes from about the early of March to end of October.
9. The average fetal number of field mice was 4.3 in Apodemus speciosus peninsulae and 4.0 in Clethrionomys rufocanus regulus.
