A survey was conducted of 1,390 citizens of Cheongju city', asking them to select 10 foods that they think are most suitable as local among 89 already- recognized local foods. The data were then analyzed by age, gender, and vocation. The results classified by sex showed that for males, first place was marsh snail soup (282), second, acorn jelly soup (174), third, bean noodle (164), and fourth, three-tiered pork and Haejang soup (158). In females, marsh snail was in first place (520), second, acorn jelly soup (322), third, bean noodle (272), fourth, three-tiered pork (271), and fifth, Haejang soup (262). Combining the results of males and females showed first place was marsh snail soup (802), second, acorn jelly soup (496), third, bean noodle (436), fourth, three-tiered pork (429), fifth, Haejang soup (420), sixth, wild plant mixture rice (323), seventh, Boshin broth (322), and eighth, minced chicken soup (321). The classification by vocation of males and females showed that fewer housewives chose three-tiered pork, while fewer clerks chose less wild plant mixture rice. Instead, housewives and clerks chose more Boshin broth and minced-chicken soup, which other males chose less. However, it is unreasonable to select wild plant mixture rice, bean noodle, or Boshin broth as the favorite local food since these can be eaten or collected only during the summer season.

The seasonal variations of primary production were investigated by phyto-PAM chlorophyll fluorometry as well as classical methods (standing crops of phytoplanktons and chlorophyll ${\alpha}$) in the Beopsu Marsh, Haman-gun, Gyeongsangnam-do. The amounts of turbidity, SS, T-N, T-P, BOD, COD, Ca$^{2+}$ and Cl$^-$ were the highest at the station 3, where located in flowout site of wastewater treated by the filtration plants. The water quality was the third level by the standard of BOD and COD. The amount of chlorophyll a (268.8 mg L$^{-1}$) was the highest at the station 2 in April because the cell density (2,677 cells mL$^{-1}$) of Micractinium pusillum increased suddenly from February (180 cells mL$^{-1}$). The patterns of primary production of phytoplankton by phyto-PAM chlorophyll fluorometry were fallen in with those of standing crops and chlorophyll a of phyto-planktons. The primary production was varied according to stations and seasons. The water environments of the Beopsu Marsh as a natural mounument should be under the control of a regular examination in order to preserve the ecosystem.

Six species of Glomus and one species of Acaulospora of vesicular-arbuscular (VA) mycorrhizal fungi associated with four salt-marsh plants(Calamagrotis epigeios, Lotus corniculatus, Artemisia scoparia and Imperata cylindrica were isolated from salt-marsh soil. The six species of Glomus were identified as G. albidum(lst type), G. pulvinatum(2nd type), G. constrictium(3rd type), G. sp.(4th type), G. caledonicum(5th type), and G. sp. (6th type). The one species of Acaulospora was identified as A. scrobiculata(7th type). Three mycorrhizal fungi, G. albidum(l st type), G. pulvinatum(2nd type) and G. sp. (4th type) among the 7VA fungi were the most abundant types. The most common type of VA fungi occurred in rhizosphere soil from each plant was G. sp. (4th type) for Calamagrostis epigeios and Artemesia scoparia equally and G. pulvinatum for Lotus corniculatus and Imperata cylindrica equally.

Background: The structures and soil factors of Suaeda glauca-Suaeda japonica zonal communities and Phragmites australis-S. japonica zonal communities were studied in salt marshes of west and south coasts of South Korea to provide basic data for coastal wetland conservation and restoration. Results: S. glauca community mean length was 67 m and S. japonica community mean length was 567 m in zonal communities, and P. australis and S. japonica community mean length were 57 m and 191 m in zonal communities. Regarding the electrical conductivity, sodium content, and clay contents in Upnae-ri, Shinan-gun, there were significant differences among zonal communities at significance level of 0.05 for two-sided t test. However, other factors were not significantly different. Conclusions: The results indicate that multiple factors such as electronic conductivity, total nitrogen level, clay, and sodium might play important roles in the formation of zonal plant communities of salt marshes.

This study was carried out to investigate the removal of 2,4,6-trinitrotoluene, nutrients such as nitrogen, phosphorous compounds in the wetland microcosms. Microcosm study indicated that TNT nutrients were more lastly reduced in the anaerobic condition. The major reductive transformation products included 2,4diamino-6-nitrotoluene (2,4-DANT) 2,6diamino-4-nitrotoluene (2,6-DANT) 4diamino-2,6-nitrotoluene (4-ADNT) 2diamino-4,6-nitrotoluene (2-ADNT). The experimental results for nitrogen removal showed that denitrification kom NO$\sub$3//$\^$-/ to NH$_3$ was dominant process at the bottom of marsh, but nitrification from NH$_3$ to NO$\sub$3//$\^$-/ was dominant on the top of marsh.

Species composition, life form, biomass and soil properties of the halophyte communities were investigated from July to September, 1982. At the reclaimed land of Sanho-ri, sand dune of Jido, salt marsh of Suncheon Bay, and Somjin River estuary of Baealdo, species numbers were 26, 14, 13 and 7, dominant species were Salicornia herbaceae, Carex pumila and Suaeda japonica, respectively. Species composition of the 4 investigated areas was 13 families, 25 genera and 39 species, and of them, 10 families, 21 genera and 24 species were attributed to halophytes. Out of 22 life forms, the representative for Jido was $ G-D_4-R_1-3-e.t$and those for the other sites were Th-G4-R5-e. Above ground biomass of all species for Sanho-ri, Jido, Suncheon Bay and Baealdo were 441.3, 202.0, 150.7 and 353.3 g.dw/m2 and the ratios of above ground biomass halophytes to all species were 93.5, 92.7, 90.8 and 100%, respectively. The leading dominant species formed a continuum according to the salt gradiant. The similarity between Baealo and Suncheon Bay was relatively high, and Jido was quite different from the others in species composition. Aster tripolium was stenohaline and appeared at the low salt concentration, but Suaeda maritima and Suaeda asparagoides were duryhaline and occured at the relatively high salt concentration.
