This study analyzed the contents of reading textbooks of Chinese-Korean $1^{st}$, $4^{th}$, and $7^{th}$ graders in Yanji, China with reference to ecological systems and values. Results showed that the literature genre of Korean textbooks in China was predominantly novels/stories(38.5%) rather than essays(13.7%), poems/verses/rhymes(16.2%) or others(31.6%). Characters were classified into 9 categories and analyzed by Bronfenbrenner's ecological paradigm. It was found that Chinese-Korean textbooks included more characters belonging to exo- or macro-systems including school, community, and government while Korean textbooks emphasized the self or the family, both belonging to the micro-system. Values in Chinese-Korean textbooks emphasized community and government. Korean textbooks emphasized individual life. Differences were more pronounced in textbooks of the upper grades.

The golf course has many problems that are a pollution of river, a extinction of habitat by destructing a forest and a simplication of species composition. Therefore, this study was carried out to examine the ecological characteristics of vascular plants in construct-reserved site of golf course. The results were as follow. The vascular plants were summarized as 342 taxa; 86 families, 231 genera, 295 species, 42 varieties and 5 forma. In the results by the location environments of vegetation, Salix caprea community and wetland species like Persicaria thunbergii were appeared in the swamp. Especially, S. caprea will be made use of promoting a landscape. In the stream, Stephanandra incisa community has a functions like an ecological axis and a corridor of wild animals. The planting technique will be applied to using Atractylodes japonica and Ainsliaea acerifolia in the lower part of Pinus densiflora and Quercus mongolica. Because Rhododendron schlippenbachii and Convallaria keiskei grew by layer in Q. variabilis community, this will be made use of natural vegetation model. The rare plants were 2 taxa; Aristolochia contorta and Iris ensata var. spontanea. To preserve their community, we will prohibit a development and remove a threatening factor. The endemic plants were 4 taxa; Salix caprea, Clematis trichotma, Spiraea prunifolia for. simpliciflora and Weigela subsessilis. The naturalized plants were 19 taxa; Rumex crispus, Bildedykia dumetora and so on. To establish the quantitative management plan, we will obtain a ecological information about a naturalized plants in accumulating by season, community and land use pattern.

This study was carried out for the purpose of presenting basic data bases for conservation and management measures of Ecological and Scenery Conservation Area in Bongsan. The analysis results of the actual vegetation showed that rate of vegetation cover were composed of 72.3% of Robinia pseudo-acacia Forest, 10.7% of Sorbus alnifoila Forest, and Sorbus alnifoila was founded as a dominant woody plant species in the Core Zone of Bongsan Ecological and Scenery Conservation Area. To investigate the vegetation structure of Sorbus alnifolia Community in Bongsan Ecological and Scenery Conservation Area, twelve $100m^2$ sized plots were set up in Bongsan. According to the classification by TWINSPAN, the communities were divided into the three groups of Sorbus alnifolia Community, Pinus koraiensis Community and Robinia pseudo-acacia Community, To analyze annual diameter growth rate for major tree species, nine sample trees from research plots were measured. Expected ages of Sorbus alnifoila trees were 27~37years, Robinia pseudo-acacia trees were 17~26 years, Pinus koraiensis, Pinus rigida, Prunus sargentii, and Quercus mongolica trees were 27~38 years. As a result, annual diameter growth rates of Robinia pseudo-acacia and Pinus rigida tended to remarkably decreased, Sorbus alnifoila had the wood on inter-specific competition of the woody plant species. Importance values of Sorbus alnifoila in the three layers of Sorbus alnifoila communities were evenly high.

Fish community structure in the Pyeongchanggang River was investigated from April to November 2009. About 900 individuals representing 24 species from eight families at six sites in the Pyeongchanggang River were collected. It was similar to the 2001's survey and it was less than 2006's survey. The Korean endemic species, Zacco koreanus was the most abundant, whereas subdominant species were native species, such as Pungtungia herzi, Zacco platypus, Rhynchocypris kumgangensis and Rhynchocypris oxycephalus. Three endangered species were collected at the sampling area, Acheilognathus signifier (relative abundance [RA] 0.9%), Pseudopungtungia tenuicorpa (RA 1.4%), and Cottus koreanus (RA 3.6%). One natural monument species, Hemibarbus mylodon, was included. According to the analysis of ecological indicator characteristics, the relative proportion of tolerant species was 6.3% (57 individuals), whereas the proportion of sensitive species was 65.9% (593 individuals). Species evenness, richness and diversity indices decreased gradually through the month from April to November during the study. Community indices in Pyeongchanggang River showed a high evenness index (J'>0.6), a low level of species richness (R<3.5) and a medium level of diversity (1.5

In urban area, urban forests work as an ecological center that mitigates the environmental pollution of the area. In order to maintain the ecological function of a forest, the management method should be established based on ht through investigation of the vegetation structure of the forest. In this study, the vegetation structure of Namsan in Kyungju area was investigated in order to study the ecological value of Namsan and to suggest a desirable management alternative. 21 plots were selected as survey areas. Using the TWINSPAN technique, the forest of Namsan was classified into four communities: Quercus serrata community(I), Castanea crenata-Q. serrata-Q. mongolica community(II), Pinus densiflora community(III) and P. densiflora-P. rigida-Robinia pseudoacacia community(IV). The survey results were summarized by five: 1) the distribution of vegetation showed 2) P. densiflora was the absolutely dominant species in Namsan, 3) number of the average species was 12.6$^{\circ}$$\pm$3.1, 4) number of individual was 131.1$^{\circ}$$\pm$47.8 per a plot(100$m^2$), 5) the results of annual ring analysis revealed that the age of P. densiflora in Namsan was about 3 0$^{\circ}$~60$^{\circ}$years old. From the above results, it was found out that the forest has two problems. One thing is maintenance of P.densiflora against succession, another is artificial forest dispersion. The problems of Namsan forest management will be solved with further studies related.
