양산천의 (梁山川) 부착규조군집에 (附着珪藻群集) 대한 연구
김맹기,김종원,이학영 ( Maeng Ki Kim,Jong Won Kim,Hak Young Lee ) 한국하천호수학회 1992 생태와 환경 Vol.25 No.1
Communities of periphytic diatoms in Yangsan stream were investigated from September 1989 to August 1990. A total of 122 taxa of periphytic diatoms belonging to 39 genera, 104 species, 16 varieties and 2 forms were identified. The number of species was more in fall and winter than in spring and summer and the important dominant species were Nitzschia palea, Cocconeis placentula, and Navicula cryptocephala. The mean of annual species diversity was 3.01 and the saprobity was oligosaprobity. Evenness showed decreasing tendency from upper reaches to lower reaches of Yangsan stream. There were no differences in similarity indices among sampled stations. Correlation coefficient was relatively high between dominancy and diversity, dominancy and evenness, and diversity and evenness.

화왕산(경남 창녕군)과 저굴산 (경남 의령군)의 식물구계와 녹세
조인숙,김맹기,김종원,이학영 부산대학교 환경문제연구소 1991 環境硏究報 Vol.9 No.-
본 조사에서 밝혀진 관속식물은 화왕산이 62과, 245종, 25변종에 포함되는 270종류였고 저굴산은 65과, 246종, 30변종에 포함되는 276종류였다. 녹지자연도은 등급 2, 3, 6, 10의 4가지가 나타났으며 평균 녹지자연도는 화왕산이 6, 저굴산은 5.76이었다. 화왕산에서는 현존량이 35,682.5t, 순생산량이 6,980t/year 이었고 저굴산에서는 현존량이 86,047.5t 순생산랴은 16,610t/year으로 나타났다. The flora of vascular plants investigated in this survey, were 270 kinds belonging to 62 families, 245 species, 25 varieties in Mt. Hwawang, and 276 kinds belonging to 65 families, 246 species, 30 varieties in Mt. Jogul. Four different Degree of Green Naturality ; 2, 3, 6, 10, have been registered and Degree of Green naturality were 6 in Mt. Hwawang and of 5.75 in Mt. Jogul. The standing crop and net primary production were 35,682.5t and 6,980t/year in Mt. Hwawang, and 86,047.5t and 16,610t/ year in Mt. Jogul, respectively.

춘산저수지 (경남 창원군)의 수생 유관속식물의 구계와 분포
조인숙,김맹기,김종원,이학영 부산대학교 환경문제연구소 1991 環境硏究報 Vol.9 No.-
춘산저수지의 수생유관속식물은 2문, 3강, 7목, 10과 12속, 16종, 4변종에 포함되는 20종류였다. 종의 다양도는 6월, 7월, 및 8월에 가장 높았고 1월에 가장 낮았으며 생활형과 생장형에 따른 분류에서는 침수성 수생식물이 가장 많았다. 본 조사지역의 수생식물은 일차생산자, 미소생물의 서식처, 초식동물의 먹이 및 철새들의 서식처로 중요한 기능을 가지는 것으로 사료되었다. Flora of vascular hydrophytes in Choonsan Reservoir were 20 kinds belonging to 2 phyla, 3 classes, 7 orders, 10 families, 12 genera, 16 species and 4 varieties. The most diverse flora of vascular hydrophytes appeared in June, July and August, and the least in january. In life and growth from analysis, submersed hydrophytes dominated in this reservoir. The important functions of vascular hydrophytes in this reservoir were considered as primary producers, habitats of microorganisms, food sources of herbivores and habitats of migratory birds.

This study was carried out to find the relationships between species pairs in the vegetation of eastern valley vegetation in Mt. KumJung from September 20, 1991 to October 15, 1992. Eight sites were selected, each being divided into 5 quadrats, and thus 40 quadrats were in total. To know the correlation among plant species the x^2 values were calculated by using the method of Yates, and the results were analyzed by cluster analysis according to Sneath and Sokal, and the following conclusions were obtained. The species examined can be subdivided into five groups according to the relationships. However, the relationships are not correlated with pH, water-content, maximum water holding capacity and mineral content of soil probably due to the environmental discontinuity.

Phytoplankton flora of Chinyang Lake and Hapchun Lake were studied. A total of 161 species(Chinyang Lake, 135 species; Hapchun Lake, 80 species) were identified. The major species of two lakes were Melosira granulate var. angustissima and M. italica. As the bloom causing species, Microcystis aeruginosa, Ceratium hirundinella, and Peridinium sp. were identified. The chlorophyll a concentration of Chinyang Lake was higher than Hapchun Lake.

The seasonal changes and composition of phytoplankton of the Choonsan reservior were studied from November 1990 to October 1991. 195 taxa which belong to 65 genera, 150 species, 40 varieties and 1 forms were identified. Species number during summer monthes was higher than that of other seasons. Standing crops of phytoplankton were varied from 7.8 × 10 exp (5) cells/ℓto 2.2 × 10 exp (6) cells/ℓ The dominant species were Cryptomonas erosa and Trachelomonas uolvocina. Chlorophyll a contents of phytoplankton was varied from 1.36 ㎍/ℓto 127.46 ㎍/ℓ. The biotic indices of phytoplankton were very similar among three sites. Saprobien-system by index of species diversity suggests that the Choonsan reservior belongs to the oligosaprophic.
