  • Nature-learning place is a critical space together with nature center in Natural parks. But there are serious faults on these design and planning as for the landscape ecological consideration. The objective of this paper was to suggest the ecological alternatives through analyzing existing cases of nature-teaming place in Natural parte. Five case sites in Natural parks were selected in Chollabukdo. Three landscape indices- subjectivity, natural prototype, nativity, were introduced for evaluating the existing cases. Results showed that those are short of landscape ecological senses- Biotope target species, ecological vegetation patches, eco-corridor concept. A proposal for the ecological planning in Deokyusan Natural park was suggested according to several criteria with biotopes as forest and stream patches and the corridor. The results of the study can be summarized as follows. First, existing natural-loaming sites should be evaluated in light of landscape ecological indices. Second, they can be designed to work with the concept of the biotope patch and corridor for target species. The results of this study could provide critical guidelines for the ecological planning and design of natural-loaming sites in nature parks.

  • The purpose of this research is to identify the selection status of the evaluation index in Korea and suggest improvements. In order to do so, comparison and analysis are conducted of terms, items and measures for biotope evaluation indexes attested in related documents published in domestic and foreign areas. The findings of this research are listed in the following. First, terms about biotope evaluation indexes are used and integrated with each other. Second, items used to denote biotope evaluation indexes are largely different in each region since comprehensive concepts have not been established for selecting the items. Third, there are poor grounds for items denoting biotope evaluation indexes to the species of creatures. Fourth, the items cannot provide satisfying explanations for the relative values of the current condition in the urban ecosystem of a specific region. The results of this research may be applied to provide basic materials about what is to be improved for selecting biotope evaluation indexes in Korea. In order to systematically preserve an urban ecosystem environment in Korea for the future, it is necessary for the state to develop and set up such evaluation indexes and guidelines that reflect the relative values of biotopes in each level of urban areas in Korea.

  • In this study, in order to examine the change of soil animals by vegetation restoration types, experimental sites with biotope restoration method, forest topsoil paving method, small diameter trees planting method and multi-layer community planting method were applied and the control site was selected. The naturalness of soil animals was analysed by studying the change of soil animals. It was confirmed that the control site has a high level of the naturalness of soil animals as it includes a mixture of fauna sensitive and insensitive to environment distributed widely over the site. The experimental site with biotope restoration method showed a similar level of the naturalness of soil animals as the control site. Furthermore, the naturalness of soil animals in the experimental sites with small diameter trees planting method and multi-layer community planting method also showed a progressive restoration although the level of the naturalness of soil animals is lower than the experimental site with the biotope restoration method. Therefore, it is confirmed that the experimental site with biotope restoration method shows a faster recovery of soil animal than other sites. This is because this method uses the portion of topsoil and subsoil that were dug from the intact forest during transplantation.

  • The main focus of this research is the establishment of a systemic evaluation model based on objective evaluation indices, which are drawn to assess the experiencing of nature and recreational value at the level of the district unit. First of all, as a result of a literature review, a total of 10 indices can be drawn including vegetation structure, pavement rate, and hemeroby to evaluate an assessment of natural experiences and recreational value. Also, as a result of expert survey analysis, all evaluation index items were above 4.4, which is a high importance average. Hemeroby and unique landscape factor items in particular were above 5.8, which is very high. In addition, as a result of implementing a factor analysis to classify evaluation indices according to characteristics, three factors arise: 'landscape structure and quality of natural experience', 'typical availability', and 'quality of aesthetic and visual sense.' Based on the above survey analysis results, the 'quality of aesthetic and visual sense' was the highest, at 3.510. The classification 'landscape structure and quality of natural experience' was the lowest, at 3.035. A systemic value evaluation model was established by comprehensively analyzing these results. To verify the validity of the evaluation model drawn, real sites are selected and applied. First of all, as a result of a biotope types classification of sites, biotope type groups are classified into a total of 13 including the stream biotope while its subordinate biotope types are classified into a total of 61 groups. Lastly, as a result of biotope value evaluation, which was a previously established evaluation model, there are a total of 16 types including vegetation-abundant natural rivers and small-scale woodlands near forests in grade I. There are 9 types in grade II, 8 in grade III, 8 in grade IV, 19 in the least-valuable grade V.

  • The purpose of this study was to analyze biotope types of urban land-use patterns. Forest areas were considered according to vegetation type and potential for succession. Urban ecosystem structure was analyzed according to land use, land coverage, vegetation structure (actual vegetation, diameter at breast height, layer structure, and revetment). As a results of the classification, the biotopes were divided into 71 types according to the urban ecosystem structure. In the case of the Hanam province, the biotopes were divided into 51 types: 26 forest types; 5 swampy and grass land types; 3 farm land types; 3 types of planted land, and 8 types of urbanization.

  • Since 1990, urban areas have been expanded rapidly due to the concentration of the population and several development projects including large scale apartment complexes and residential developments. Due to these development projects, the quality and functions of ecosystems have been continuously degraded, regardless of public agencies' efforts introducing development index, guideline, and amendment of law for sustaining the quality of ecosystems. Substantial guideline and content cannot expect the sustainable maintenance of nation's natural resources. Recent improve this situation, ecological planning was introduced, but research data of environments and objective systems were not enough showing the limits. The purposes of this study were to reduce the urban sprawl caused by residential development plans for environment-friendly residential developments, to establish applicable ecological planning, and to suggest the land use plans that reduce adverse effects of developments to nature ecosystem.

  • Distribution, population structure, and growth of the bivalve Protothaca euglypta were investigated for clams collected from the northwestern part of the East Sea of Russia. This species is distributed in further northern area than it was found earlier. In the southern area, this clam is found in the intertidal zone, up to 8 m in depth. It is one of the most numerous infaunal species of bivalves, and protected to wave action in the gravel-pebble and sand with rubble biotope. Population density of P. euglypta reaches 500 $spc./m^2$, and biomass 2 $kg/m^2$. Size and age composition of the local settlements and allometric growth of P. euglypta depend on a biotope. The growth rate of P. euglypta considerably reduces in case of the northern boundary area, whereas life span increases.
