Abstract

The purpose of this study is conducted to examine the change of flora and fauna in the extensive rooftop green area from 2005 to 2009. The experimental site is on the rooftop green area of Seoul Women's University which was constructed in 2005. This research was consisted of four parts: soil, potted plants, invading plants and small animals especially insects. The plants were surveyed by enumeration, while animals were surveyed by two methods which are 'Netting and Searching' and 'Pit fall trap'. The initial group of plants planted in 2005 was 100 species of 26 families whereas in 2009 there were 62 species of 23 families including 22 invading species of 11 families. In case of insects in 2009, 21 species of 7 families (9 orders) were detected; 19 species of 15 families (8 orders) were discovered by 'Netting and Searching' and 5 species of 5 families (5 orders) by 'Pit fall trap'.

본 연구는 기 조성된 옥상녹화지의 동 식물상 모니터링을 통해 옥상녹화지의 생태적 변화를 관찰하기 위한 목적으로 수행되었다. 대상지는 서울여대 행정관 옥상녹화지역으로 조성 당시인 2005년과 2009년 현재 식재 식물의 생존여부와 이입식물, 출현 동물군 중 곤충을 중심으로 비교 분석하였다. 식재당시인 2005년의 경우, 식물은 식재종 26과 100종이었으나, 2009년 조사 결과 23과 62종으로 나타났다. 이 중 식재식물은 14과 40종으로 줄었으며, 이입식물은 11과 22종이 출현하였다. 곤충은 2009년 총 9목 7과 21종이 출현하였으며, 육안조사법으로 8목 15과 19종, 먹이 유인포획법으로 5목 5과 5종이 발견되었다. 곤충은 주로 비행하여 대상지에 출현한 것으로 보이며, 문헌조사로 밝혀진 곤충의 특성과 연관하여 분석한 결과 대상지의 식물을 식수로 이용하거나, 서식처로 사용하는 등 식물과 밀접한 연관성을 보였다.
