본 연구에서는 동해시에 분포하는 7개 습지에 대해 수질과 야생동식물의 분포를 조사하고 분석하였다. 조사결과, 대부분 습지의 수질은 오염물질의 외부유입에 의해 부영양화 상태로 나타났다. 식물은 총 234분류군으로 69과 168속 207종 24변 종 3품종이었으며, 이 중 습생식물은 18종, 수생식물은 43종으로 나타났다. 산림청 지정 희귀·멸종위기식물 2종, 귀화 식 물은 27종이 확인되었으며, 도시화 지수와 귀화율은 각각 8.4%, 11.6%로 나타났다. 저서성 대형무척추동물은 총 3문 5강 12목 26과 35종이 확인되었고, 희귀종은 3종이 발견되었다. 어류는 총 5과 5종이 서식하였고, 멸종위기 야생생물에 Ⅱ급 1종이 발견되었다. 대부분의 습지는 그 면적이 비교적 작고, 일부 습지는 산림 및 하천의 원거리에 고립되어 분포하는 등 외부종의 유입 및 유출의 제한이 있었다. 하지만, 특정 종을 포함한 다양한 동식물의 서식이 확인되었으며, 향후 습지 유 지 및 기능 제고를 위한 대책이 요구되었다.

In this study, we investigated and analysed the water quality, distribution of the vegetation and the wildlife to seven wetlands in Donghae city. As a result, most of the wetlands was found to be very poor water quality and some specific pollutants from entering the wetland. A total of 234 taxa on vegetation were identified including 207 species, 24 varieties, 3 formaes, 168 genera and 69 families. 2 species were recorded as designated rare plant of Korea Forest Service. The naturalized plants were 27 species. The urbanization rate of naturalization index was 8.4% and 11.6% respectively. The number of benthic macroinvertebrate taxa was 35 species, 26 families, 12 orders, 5 classes and 3 phylums. Rare species were recorded 3 species. Taxa for fishes were 5 family and 5 species. Endangered wildlife was found 1 species. Most wetlands in Donghae city were the relatively small in size, and some wetlands were separately located from forest and river ecosystems. It was limited inflow and outflow of species into a wetland from the outside. However, various vegetation were found at whole wetlands and some special species also inhabited. The wetlands performed the role as a habitat of wild life.
