초록

도시의 기온 변화에 따른 야생조류 종의 변화를 파악하기 위하여 월드컵공원을 대상으로 2003년부터 2008년까지 22회에 걸쳐 계절별 야생조류 출현현황을 조사하였으며 서울시 기온과의 관계를 분석하였다. 6년 동안 월드컵공원에서 출현한 야생조류는 총 15목 38과 102종이었다. 6년간 시간의 흐름과 통계적으로 유의미한 관계를 보인 야생조류는 직박구리였으며 점점 증가한 것으로 나타났다. 서울시의 계절별 평균기온과 야생조류 종과의 관계를 알아보기 위하여 출현종 중 30% 이상의 출현빈도를 보인 31종을 대상으로 회귀분석을 실시하였다. 회귀분석결과 31종 중 7종이 유의한 상관관계를 보였다. 까치, 쇠박새, 흰뺨검둥오리, 청둥오리, 말똥가리 5종은 유의한 음의 상관관계를 보여 지구온난화에 따른 기온 상승이 지속된다면 개체수가 감소하거나 서식지 이동 가능성이 있는 것으로 판단되었다. 반면에 황조롱이와 꾀꼬리 2종은 유의한 양의 상관관계를 보여 기온 상승에 따른 개체수 증가로 서식지 확대 가능성이 있었다. 이러한 결과로 향후 지구온난화에 따른 온도 상승이 야생조류 종 구성 변화에 영향을 미칠 것으로 판단할 수 있었으며, 기온과 상관관계가 있는 7종의 야생조류는 기온 상승에 따른 서식지 변화 가능성이 높아 기후 변화에 따른 지표종이 될 가능성이 있었다.

To see the influence of bird species by the change of temperature in city, we have carried out bird census 22 times for 6 years from 2003 to 2008 in Worldcup Park, Seoul. And we analysed the correlation between the temperature of Seoul and wildbirds. 15 orders, 38 families and 102 species were confirmed to have existed. We could find that Hypsipetes amaurotis gradually turned out to have increased with statistical significance for 6 years. To analyze the relationship between the temperature of Seoul and wildbirds, we have chosen 31 bird species observed more than 30% in frequency and proceeded the regression analysis. The survey shows that with the temperature rise the number of the resident birds such as Pica pica, Parus palustris, Anas platyrhynchos and Anas poecilorhyncha and the migratory birds such as Buteo buteo has declined. These 5 species have a possibility to be decreased as a global climate warming and maybe move to another habitat. In contrast, Oriolus chinensis and Falco tinnunculus are characterized into the species that increased due to the rising temperature. So they have a posibility to increase and expand their habitat. This survey shows that temperature rise can cause to change the composition of bird species. And 7 bird species related with the change of temperature have a great possibility as a indicator of the climate change.
