This study was conducted to find the structure of phytoplankton community in the Hoeya river(Ulsan) from March 2000 to February 2001. The taxa of phytoplankton identified included 135 species, 5 divisions, 33 families and 82 genera. Among them, chrysophyta(diatoms) were 63 species(46.7%), chlorophyta(green algae) 47 species(34.8%), pyrrophyta(dinoflagellates) 13 species(9.6%), cyanophyta (cyanobacteria) 8 species(5.9%) and euglenophyta(euglenoids) 4 species(3.0%) respectively. Ecological important species is called frequently appearing species, red tide causative species, seawater species and pollution indicator. 22 species including Aulacoseira granulata were recorded frequently appearing species. 19 species including Ceratium furca were recorded as red tide causing species. And the pollution indicators were 33 species including Actinastrum hantzschil var. fluviatile. The highest standing crops were 3,103,441 cell/ℓ in August at the RW-1 and the lowest 1,245 cell/ℓ in January at the RW-5. In the community analysis, the dominanance indices ranged from 0.34(October, RW-2) to 0.94(January, RW-1) and the diversity indices from 0.50(May, RW-2) to 2.57(September, RW-2). The saprobic indices were 2.43 in RW-1, 2.41in RW-2, 2.375 in RW-3, 2.40 in RW-4, 2.43, in RW-5. Therefore, these areas were investigated "β-mesosaprobic". According to the similarity index among the stations, these areas were defined as residential district areas(RW-2 and RW-3), lower part of the dam (RW-1) and seawater areas(RW-4 and RW-5).

To investigate the flora of wetland at Mt. Il-Kwang, the helophyte of the mountain was examined. The flora observed was classified into 2 phyla, 15 families, 27 genera, and 34 species. Representative species at the wetland were Drosera rotundifolia, Utricularia racemosa, Utricularia bifida, Eriocaulon miquelianum, and Eleocharis attenuata var. laeviseta. In the lower part of the wetland, water was abundant and soil surface layer was thin, and Eriocaulon miquelianum-Carex canescens-Drosera rotundifolia community were developed. On the other hand, in the upper part of the wetland, water was not abundant and soil surface layer was thick, and Agrostis clavata-Phragmites japonica community were developed. Utricularia bifida and Utricularia yakusimensis were growing abundantly at this wetland, but Utricularia racemosa was few in number and narrow in the distribution area. Eriocaulon miquelianum, a Korean endemic plant, was observed, and Habenaria linearifolia, Spiranthes amoena, and Epipactis thunbergii, the CITES plant, were observed at this wetland. Insectivorous plant such as Drosera rotundifolia, Utricularia racemosa, Utricularia bifida, and Utricularia yakusimensis were also observed.

This study was focused on the investigation of the phytoplankton flora and community structure for changing of water environment at the rivers in the lower part of Nakdong river. The samples for this study were collected every month from Jan. 2004 To Dec. 2004. the 196 species belonged to 94 genera were identified during this study periods. The number of species was recorded the maximum 124 taxa in summer and the minimum 69 taxa in winter. We observed the maximum taxa (92 taxa) at the site No. 20 and the minimum taxa (55 taxa) at the site No. 8, respectively. Among the phytoplankton communities, diatoms were dominated over 40% of total phytoplankton groups. Subdominant groups were green algae (over 20% of total phytplankton groups). During this study periods, the 60 species were investigated ecologically significant species (46 cosmopolitic species, 25 pollution indicator, 21 redtide causative species, 8 dominant species, and 7 frequently occurred species). According to the cluster analysis by similarity index, the study sites could be divided into 4 groups. 본 연구는 낙동강 하류 20개 지점에 대하여 주위 환경 변화에 대응하기 위하여 식물플랑크톤상과 군집구조에 대한 조사를 실시하였다. 식물플랑크톤상과 군집은 2004년 1월부터 12월까지 매월 1회 조사하였다. 조사기간 동안 식물플랑크톤은 총 94속 196 분류군이 동정되었는데, 여름에 124분류군으로 가장 많은 종이 출현한 반면 겨울에 69분류군으로 가장 적은 종이 출현하였다. 지점별 총 출현종수는 낙동강 하구인 지점 20에서 92분류군으로 가장 많았고 지점 8에서 55분류군으로 가장 적게 출현하였다. 분류군별 출현비율은 모든 계절에서 규조류(diatoms)가 40% 이상으로 가장 높았고 녹조류(green algae)가 20%, 다음으로 남조류(blue-green algae) 등의 순으로 조사되었다. 조사기간 동안 생태적 주요종은 60분류군이 조사되었는데, 그 중 광분포종은 46분류군, 오염지표종 25분류군, 적조원인종 21분류군, 우점종 8분류군, 출현빈번종 7분류군이었다. 지점간 유사도지수에 의한 군집분석의 결과, 20개 지점은 4개의 그룹으로 분류되어졌다.

한 고장 [촌락·부락]에 관련된 민속학, 문화인류학 또는 역사, 사회적 측면에 의거한 지지에 관한 연구가 본격적으로 논의된 것은 일인들에 따른 것이다. 그들은 조선을 침략·정복하고자 하는 식민지 정책의 일환으로 당시 우리나라의 제반 문제를 다루었다. 특히 조선총독부와 경성제대 교수들에 의한 한국 관계의 연구·조사, ‘생활상태 조사’, ‘부락제’,·‘민속신앙’ 관계 논저를 비롯한 ‘방언’ ‘지지’ 등은 그 대표적 업적이라 하겠다. 물론 그 이전에 이미 간행된 이조시대 풍속지 및 지방지가 없었던 것은 아니나 적어도 학적인 체계를 갖춘 조사와 연구는 일인들에 의하여 본격화 된 것이다.
