The purpose of this study is to derive policy suggestions and new orientations for biotope mapping in Korea from a review of case studies on the classification of biotope typesin Germany. This study was conducted in the following manner: First, the related literature and data on biotopes in Germany was collected. Second, the representative examples at the provincial government level and urban and residential areas were selected. Finally, the characteristics of biotope types, biotope classification systems, and biotope classification criteria were reviewed. The results of reviewing the case examples in Germany are as follows: First, the biotope types at the provincial government level were composed of patterns which existed mostly in natural areas and the corresponding areas of their conditions. Those in urban and residential areas were made up of patterns which were distributed in urban areas and their peripheries. Second, the biotope classification systems at the provincial government level consisted of three steps:large, medium and small. Those in urban and residential areas were made up of two steps: medium and small. However, it is strongly recommended to introduce the biotope classification system composed of three steps. Third, the biotope classification criteria at the provincial government level considered ecological factors and anthropogenic factors except land use forms. Those in urban and residential areas reflected mostly anthropogenic factors and ecological factors. In conclusion, this study suggests that future biotope surveys and mapping in Korea should be investigated not only in urban areas but also in natural and semi-natural areas. In addition, a specified biotope type classification system should be established in Korea.

본 연구는 효율적 비오톱평가를 위해 일반적으로 적용할 수 있는 평가항목 및 평가체계를 개발하고자 하였다. 이를 위해 지금까지 선행된 연구사례들을 비교·검토하여, 현실적 적용가능성이 높은 비오톱 평가 항목 및 평가체계(안)을 도출하고, 선정된 사례지역의 적용과 자문회의 등의 계속적인 피드백 과정을 통하여 효율적인 비오톱평가를 위한 평가항목 및 평가체계를 제안하였다. 첫째, 비오톱평가를 위한 항목으로는 자연성 및 헤메로비, 다양성, 면적, 고립성 및 연결성, 복원능력, 희귀성 등 6개 항목을 제안하였다. 둘째, 비오톱 평가체계는 1단계 평가인 전체 비오톱유형에 대한 평가와 2단계 평가인 개별 비오톱에 대한 생태적 보전가치평가로 구분한다. 유형평가단계에서는 자연성 및 헤메로비와 다양성 항목을 중심으로 평가하고, 개별평가단계에서는 고립성 및 연결성, 복원능력, 희귀성 등과 같은 항목을 중심으로 평가할 것을 제안하였다. 그러나 비오톱평가는 지역의 특성이 고려되어야 하므로, 본 연구에서 제안된 평가항목 및 체계를 기반으로 하여 지역의 상황과 여건에 맞는 평가항목 및 지표들을 충분히 검토하여 선택하고 필요시 세부평가지표들이 추가 보완되어야 할 것이다. The purpose of this study is to derive the usually applicable evaluation items and system for the effective biotope assessment. For this purpose, the evaluation items and system for the biotope assessment be applicable to actuality are drafted by a review on the preceded case studies until now at the inside and outside of the country. And then this study proposed the evaluation items and system for the effective biotope assessment through continual feed back such as field applications in selected case study areas and consultations. First, the six items such as naturalness & hemeroby, diversity, size of area, isolation & connection, restoration ability and rarity for biotope assessment were suggested. Second, the assessment system is divided into the first step assessment as evaluation for the whole biotope types and the second step assessment as evaluation for ecological conservation value of individual biotope. This study suggests that the items such as naturalness & hemeroby and diversity should be evaluated in assessment step for biotope types and the items such as isolation & connection, restoration ability and rarity in assessment step for individual biotope. However, this study suggests that the evaluation items and indicators suitable to the regional conditions should be reviewed enough and selected and also the detail evaluation indicators should be supplemented with the foundation of items and system for biotope evaluation proposed in this study because the biotope evaluation should consider regional characteristics.
인간의 영향에 따른 도시지역 식물종의 분포 패턴 및 특성

본 연구의 목적은 인간의 간섭 및 영향에 따른 도시지역에서의 식물종의 분포패턴 및 특성을 분석하는데 있다. 전주시에서 자생적으로 이입된 모든 유관속 식물종에 대한 포괄적 자료습득을 위하여 각 1헥타 크기의 106개 표본 조사구가 분석되었다. 이러한 표본조사구는 전주시의 전형적인 토지이용유형을 대표하고 도심지역으로부터 다양한 이격거리를 갖도록 선정되었다. 종풍부성, 생활형의 패턴 그리고 외래종의 비율이 표본조사구의 헤메로비 정도와의 관계에 대해서 분석되었다. 식물종의 수는 적당히 영향을 받는 부지에서 가장 높게 나타남을 알 수 있었다. 이는 적당한 교란은 종풍부성 증가를 유도한다는 중간 교란 가설에 상응하는 결과이다. 인간의 영향을 가장 많이 받는 부지의 식물상은 일년생 식물과 외래종의 비율이 가장 높은 특징을 보였다. 그리고 일부 식물종들은 토지이용유형과 도시구역에 상응하는 유사한 분포를 갖는 세가지 그룹인 도시지역 기피종(땅비싸리, 졸참나무, 개옻나무 등), 도시지역 및 외곽지역에 널리 분포하는 종(닭의장풀, 개망초, 박주가리 등)과 도시지역 선호종(애기땅빈대, 개쑥갓, 서양민들레 등)으로 구분되었다. The purpose of this study is to analyze the distribution patterns and characteristics of plant species by human impact in urban areas. In order to achieve a comprehensive data acquisition of all autogenously introduced vascular plant species occurring in the city of Cheon-ju, this study made an analysis of 106 sample plots, each with a size of one hectare, These sample plots were selected to represent the typical land-use patterns within the city of Cheon-ju and to cover the various distances from the city center. Species richness, patterns of life forms, and the percentage of non-native species were analyzed in relation to the degree of hemeroby of the sample plots. It was found that the species number appeared the largest in sites that were moderately influenced. This result corresponds to the intermediate disturbance hypothesis that moderate disturbance leads to an increase in species richness. The flora of sites which were subject to the highest level of human impact, was characterized by a high proportion of annual species and non-native species. In addition, some species were divided into three groups with similar distribution corresponding to land-use type and urban zone: urbanophobic (e.g. Indigofera kirilowii, Prunus sargentii, Rhus trichocarpa), urbanoneutral (e.g. Commelina communis, Erigeron annuus, Metaplexis japonica) and urbanophilus (e.g. Euphorbia supina, Senecio vulgaris, Taraxacum officinale).
