한국자연보호학회의 첫 연구논문집 창간호가 출간되었습니다. 지난 11월 말 학회의 창립총회를 마친 후 바로 시작한 연구논문집 발간 준비는 그간 여러 가지 어려움을 잘 극복하면서 드디어 창간호를 탄생시켰 습니다. 한국자연보호학회의 연구논문집은 자연보호학회가 관련된 여러 학문분야를 잘 조화시켜 자연보호분야에 새로운 지평을 열기 위하여 논문 선별과 심사에 많은 정성을 기울였습니다. 생물과 그 서식지 환경을 과 학적으로 파악하고, 무분별한 개발행위에 의한 파괴를 막거나 완화하기 위한 방안을 자연보호학회 연구의 중심축으로 하였습니다. 따라서 호수, 하천, 습지, 갯벌, 사구, 만, 산림, 농경지, 특징적인 지형과 기상현상 등 야생생물의 주요 서식지 보호와 관련된 분야가 주요 분야의 하나가 될 것이고 이러한 서식지 보호와 관련된 정보를 수집하고 정리하는 정보 관련 학문도 중요한 분야의 하나가 될 것입니다. 또한 자연보호 관련 철학을 개발하고 교육하는 자연보호 철학과 교육분야도 중요 분야의 하나가 될 것입니다. 자연보호 현장에서 경험한 여러 사례들에서는 이러한 주요 생물 서식지 파괴가 서식지 주변의 빈곤문제와 직접 관 련되어 있음을 보이고 있습니다. 이와 같이 자연보호를 사회적 방법으로 접근하는 분야도 또한 본 학회의 주요 분야가 될 것입니다. 따라서 본 학회의 연구물은 많은 연구 분야를 아우르면서도 단순한 사실의 나열에서 벗어나 자연보호를 위한 방안을 위한 기초적인 지식이나 구체적인 방안과 관련된 연구를 모색할 것입니다. 수천년 유지되었던 우리 국토는 20세기 후반에 급속한 변화를 겪었고 그 과정에서 우리의 주변에서는 우리의 역사속에서 사실로서, 혹은 우화속에서 친숙했던 수많은 야생생물들은 자취를 감추고 말았습니다. 호랑이와 늑대, 여우는 이미 사라져 버렸고, 곰, 산양, 사향노루 등은 그 일부만 남아 그 생물과 서식지의 복원을 위하여 엄청난 비용과 노력을 요구하고 있습니다. 이러한 복원 노력이 수많은 시행착오를 통하여 적당한 방안이 나올 때에는 이미 어떤 생물들은 자취를 감춘 후인 경우도 많았고 그러한 노력을 통해서 도 원래의 서식지는 회복되기 어려운 경우를 많이 보아왔습니다. 1980년대의 경제적 발전과 1990년대 후반 우리에게 닥쳐왔던 경제 위기는 자연보호에 대한 관심을 많 이 퇴색시켰고 이러한 위기를 극복하는 과정에서 우리는 자연유산으로 소중한 자연환경을 파괴하여 왔습 니다. 몇 년후 시화호가 완성되면 바다로 흘러들던 우리의 큰 강들은 모두 댐이나 하구언으로 막혀 자연 의 모습과 기능을 가진 강들은 하나도 남지 않게 됩니다. 우리들은 오랫동안 인간에 의해 파괴된 자연은 시간이 흐르면서 원래의 모습과 기능이 회복되는 줄 알 아왔습니다. 그러나 최근의 경험에서는 한번 파괴된 자연 환경은 원래의 구조와 기능을 회복하지 못하는 사례도 많이 보아 왔습니다. 생물의 서식지가 파괴되면 복원되기 어려운 것과 마찬가지로 해안의 사구나 하구, 만, 갯벌, 습지 등도 그 복원이 어렵다는 인식을 하는 데 비싼 교육비를 지불한 셈입니다. 우리 학회에서는 이런 때에 즈음하여 생물과 그 서식지의 중요성을 인식하고 그의 보호와 교란의 완화 를 위한 연구를 결집하려고 합니다. 앞으로 한국자연보호학회지를 통하여 자연보호분야의 좋은 논문이 우리나라뿐만 아니라 세계적으로 우 수한 연구 결과가 되도록 회원 여러분의 협력을 바랍니다. 끝으로 오늘의 창간호가 발간되기 위하여 창립시부터 동분서주한 편집위원회 여러분들과 소중한 원고를 보내 주신 저자 및 심사위원 여러분의 노고에 깊이 감사드립니다.

To identify factors affecting the regeneration of Abies koreana, we examined environmental conditions on Mt. Halla. In three seedbed types (Sasa site, shade by rock, forest floor), we investigated temperature and soil moisture content. Stratified A. koreana seeds were placed on each seedbed types and counted germinated seedlings. Snow cover period in north-facing slope, 102±17 days, was significantly longer than that of southfacing slope, 94±14 days. Average temperature of May to July, the period of seed germination, was significantly lower in forest floor than around rocks and under Sasa quelpaertensis. Germination rate of on each seedbed types was not different. This study suggests that the proper environmental conditions of A. koreana's regeneration may be affected on more complex factors.

Most of the extensive areas in the lower parts of the Nakdonggang River are characterized as zones of the diversely geomorphological features: the riparian wetland and floodplains, the riverine sand island on the river channel and riverine wetlands along the river. It aims to introduce the floodplains of the Nakdonggang River and its tributary (Hwapocheon Stream), and to evaluate their utilities in the process of the watershed management and the stream restoration in future. The lowland floodplains are developed over the 1,000 ha area beyond the riverbank in the middle and lower parts of the river. Furthermore, the 19 sand islands distribute on the river channel and the riverine wetlands are situated over 11 locations along the riverside. The most floodplains along the river had been converted to agricultural and other land uses, especially paddy fields, and two wetlands - the Hwaponeup Wetland in the Hwapocheon Stream and the Wooponeup Wetland in the Topyeongcheon Stream - barely keep in existence of the natural type one. In the Hwapocheon Watershed, the lowland below the 50 m elevation covers 61% of the basin area and the wetland interiorly spread along the stream bank. The area of the Hwaponeup Wetland is 250 ha to rank second level next to Wooponeup Wetland in sizes or scopes of inland ones. The Hwaponeup Wetland displays a unique landscape with the various willowtree population and waterside plants to have the high biological diversity. The 448 ha floodplain area in the lower zone and the 259 ha area in the mid-zone of the stream had been already reclaimed in the past, and in the present, the lowland floodplains around the stream-type wetland had been exclusively occupied with the paddy farms. In recent year, as the wetland and floodplain restoration have emerged as a key component in local watershed management programs over the world, these lands should have the greatest potential for future ecosystem recovery and restoration because the ecological values of the Hwapocheon Stream could increase more than those of the other areas. The restoration, creation and enhancement of the wetland provides opportunities for solving existing flood control or erosion, ecological habitat or biological diversity, other water resource problem. In these context, the network systems to connect the stream channels and riparian floodplains are a basic concept in the watershed management. In view of the natural resources, the Hwapocheon Stream will have the better advantage to control the flooding and water quality in the process of the stream restoration or watershed management in the local area.

Weather is an important variable to form the characteristic natural ecosystem of the region along with topography and soil. Since the ecosystem change is expected by the global warming, the preparation for the change has to be made to accumulate the investigative data for the relationship on local weather and ecosystem. As the study method, the measurement data and sea surface temperature data were analyzed and the atmospheric model was performed. As the result, the weather characteristics, changing patterns and the causes of the weather change in Ulreungdo and Dokdo regions could be analyzed. For the last 67 years since the weather measurement was started in Ulreungdo, annual temperature elevation rate was 0.013oC and 0.88oC was elevated for 68 years, and the temperature elevation rate during the winter season recorded the highest elevation rate of 0.024oC/year. The amount of rainfall in Ulreungdo has been significantly increased recently. The strength of a typhoon that had affects on the peninsula and the increase of rainfall was mainly attributable to the increase of sea surface temperature alleviation at the East Sea. Sea surface temperature near Ulreungdo and the weather of the Ulreungdo weather station has high correlation each other. The acute sea surface temperature elevation could be assumed to cause the temperature elevation in Ulreungdo. According to the weather model of MM5, the simulated effect of sea surface temperature elevation on the atmospheric temperature resulted the average 1.3oC temperature increase in Ulreungdo as the sea surface temperature was increased 2oC. Therefore, it was able to confirm that the major reason of temperature elevation at the Ulreungdo weather station was attributable to sea surface temperature elevation.

This study was to establish the floristic composition of resources vascular plants of North-East slope in Mt. Songni (1,057.7 m). This work was investigated during the period of April to October 2006. Resources vascular plants were composed of 79 families, 215 genera, 296 species, 4 subspecies, 33 varieties and 6 formae, totaling 339 taxa. Among the investigated resources plants, 15 taxa (2.63%) were Korean endemic species. The special plants based on floral region by Ministry of Environment were 38 taxa; V rank species 2 taxa, IV rank species 2 taxa, III rank species 10 taxa, II rank species 10 taxa and I rank species 14 taxa. A naturalized plants were 8 species, correspond to 2.74% of totaling 292 naturalized species appeared in South Korea.

Soil texture, pH, organic carbon, organic matter, organic nitrogen, total phosphorus and chemical speciation were studied on the soil samples from Dok-do, Korea. Dok-do soil was composed mostly of silt, and textures were silt and silt loam. Soil pH was normally neutral but in some areas, acidic and very high content of organic matter. High content of organic matter explained the origin of Dok-do soil was related to the vegetation of the island. C/N ratio of the soil organic matter 15 meant the organic matter in the soil had moderately degraded plant debris. The most important chemical speciation of soil phosphorus in Dok-do was Residual P, meant the source of soil phosphorus was plant, and high ratio of Apatite P was considered to relate to the feces of water bird of the area.

This survey was carried out to investigate the flora of Micheongol nature recreation forest at Yangyang. Vascular plants surveyed were consisted of 285 taxa, i.e., 254 species, 2 subspecies, 28 varieties, and 1 formae. Korean endemic plants were Cirsium setidens, Viola diamantica, Hanabusaya asiatica, Deutzia coreana, Aster koraiensis, Tilia taquetii, Vaccinium hirtum var. koreanum, Salvia chanryonica, Filipendula glaberrima, Tilia rufa, Salix caprea and Anemone koraiensis. Also, the conservatory plants classified from first to fifth grade were distributed 47 taxa in the Micheongol nature recreation forest area. The naturalized plants were found 12 taxa. Especially, Leontice microrrhyncha S. Moore, rare and endangered species, was found in this area firstly.
