Provisioning service, which is one of the ecosystem service functions, means goods and services such as food and fuel that people get from ecosystem. Provisioning functions are closely related to the primary industry, a sector of economy. Excessive demand and use of human society can cause trade-offs among regulation, cultural, and supporting services. Therefore, it is important to perform evaluation ecosystem services periodically and to monitor the time series fluctuations to identify the impact of provisioning services on other ecosystem services (trade-off) and to maintain sustainable provisioning service. When it comes to the precise assessment of provisioning service, it is necessary to get the statistical data and standardize indicators and methods. In this study, indicators and methods, which are applicable to the spatial level of national-local-protected areas, were derived through literature analysis and expert survey. The result of this study implies that provisioning services measurement by spatial level improve the efficiency of the establishment of environmental conservation plans by whose purpose.

Field surveys were conducted at a total of 50 locations targeting naturalized plants on Ulleung-do. A total of 109 taxa were identified, including the list of naturalized plants in the preceding literature. The naturalized plants of Ulleung-do had a high proportion of Asteraceae, which appeared frequently in the habitat of the ruderal type. There were no naturalized plants that settled only on Ulleung-do, and all naturalized plants found on Ulleung-do first settled on the Korean Peninsula. This was proved by the high rates of epecophyten (90.8%) and the introduction period 2nd (70.6%). On the other hand, among ecosystem-disturbing species that have a great influence in the inland of the Korean Peninsula, Hypochaeris radicata and Rumex acetosella appeared in a limited area in Ulleung-do. On the other hand, Lapsana communis appeared in high density along the forest edge, requiring management of naturalized plants different from those in the Korean Peninsula. Naturalized plants on Ulleung-do showed a rapid increase in the 1990s after increased academic research, coastal road development, and other development projects. This highlights the necessity for continuous research on the pattern of naturalized plant occurrence after the completion of the Ulleung Airport, which is currently under construction.

The objective of this study is to seek for improvement measures to make the Ecosystem and Nature Map by analyzing causes for grade changes and distributional characteristics of areas with public objections to the Ecosystem and Nature Map notified by e-official gazette from 2014 to June 2016. The receipt of public appeals has been recently increased from average 23 cases a year(2007-2013) to average 33 cases a year(2014-June 2016) while there were 42 areas with public appeals for less than the minimum area($62,500m^2$) for the evaluation of grade of the Ecosystem and Nature Map. Most of the public appeals focused on the 1st grade zone of the Ecosystem and Nature Map. Before grade changes by public appeals, the 1st grade zone of the Ecosystem and Nature Map were 76.0% of the whole areas with public appeals. However, after grade changes by public appeals, it was rapidly decreased to 25.2%, which means that a lot of the 1st grade zone with public appeals were lowered. In the results of analyzing the distributional characteristics of areas with public appeals, they were mostly distributed in lowland(less than 250m altitude), section with $10{\sim}20^{\circ}$ slope, and areas close to or within 100m from built-up area. Regarding areas with public appeals, the biggest time difference between the period of the existing research by National Ecosystem Survey and the period of notice after completing the treatment of public appeals was 18 years while areas showing 6-15 years of time difference were about 70%. Thus, there were huge differences in time of research and notice. Also, the biggest causes for grade changes were boundary errors caused by small-scale survey, and then followed by changes in evaluation of endangered species and occurrence of built-up area and damaged land. Analyzing areas with public appeals in each evaluation item of the Ecosystem and Nature Map, vegetation part was 73.0%, and endangered species area was 23.1% while topography and wetland was less.

경관의 보전과 복원, 계획은 생태계내의 다양성을 보전하고 유지하기위한 전반적인 통합관리 체계하에서 조직적인 운영이 요구되는 사항이다. 유전자수준에서부터 서식지, 생태계 및 경관수준에 이르기까지 생물의 다양성을 유지하고 개체군을 보전하며, 관리하기 위한 세계 여러 국가들의 전략과 노력은 주요거점서식지를 서로 연결하는 서식지 네트워크를 비롯하여 주요 동물이동통로에 대한 생태통로의 설치 및 훼손된 지역에 대한 복원에 초점을 두고 있다. 최근에는 유럽에서는 이러한 서식지 수준의 네트워크를 인접 국가간에 공동으로 조직하여 관리하는 국가간 생태네트워크를 서두르고 있다. 경관수준의 서식지 및 생태계의 보전과 관리에 있어 핵심적 개념으로 떠오르고 있는 경관생태학 및 보전생태학적인 이론은 생태네트워크 개념에서도 그 중요한 원리가 활용된다. 본 서술형논문에서는 유럽의 생태네트워크의 운영활동을 참고하여 한국의 서식지 보전 및 관리를 위한 생태네트 현황에 참고하고 하였으며, 여기에 개괄적이며 필수적인 경관생태학적 고려사향을 논하였다. 우리나라의 서식지 및 경관 수준의 네트워크전략과 환경정책의 수립에 있어 고려되어야 할 사항을 서식지 보호, 법적 접근 그리고 생태네트워크 프로그램을 중심으로 기술하였다. 향후 통일을 대비하면서 통일 이후의 남북간의 접경지역을 포함한 자연보전지역과 특수한 경관지역을 관리하고 보전하는데 유럽외 국가간 생태네트워크 프로그램은 주요한 우리 환경정책에 주요한 메시지를 주고 있다.

The most important thing to successfully restore an oak forest is finding suitable climatic conditions and topographic factors for the oak species to be introduced. In this study, in order to find suitable environmental conditions for the five dominant oak trees on the Korean Peninsula, we carried out analysing the information on the location of forest vegetation on the Korean Peninsula. The range of annual mean temperature of the five oak trees was narrow in the order of Q. mongolica (7.7~14.3℃), Q. variabilis (9.2~13.8℃), Q. acutissima (10.5~14.3℃), Q. serrata (11.4~13.7℃), Q. aliena (11.0~12.9℃). The range of annual precipitation of oaks was narrow in order of Q. mongolica (1072.7~1780.9 mm), Q. variablis (1066.6~1554.9 mm), Q. acustissima (1036.5~1504.8 mm), Q. serrata (1062.6~1504.7 mm). The range of altitude was in order of Q. mongolica (147~1388m), Q. serrata (93~950m), Q. variabilis(90~913m), Q. acustissima (60~516m), Q. aliena (55~465 m). The range of slope was in the order of Q. mongolica (8~56°), Q. variabilis(5~52°), Q. serrata (11~45°), Q. aliena (15~38°), Q. acustissima (16~37°). These results are considered to be very useful in the case of ecological restoration using deciduous oak trees on the Korean Peninsula.

Distribution of fish community depends largely on environmental disturbance such as habitat change. In this study, we evaluated the impact of environmental variables and microhabitat patch types on fish distribution in Yudeung Stream at 15 sites between early May and late June 2019. We used non-metric multidimensional scaling to examine the distribution patterns of fish in each site. Gnathopogon strigatus, Squalidus gracilis majimae, Zacco koreanus, and Zacco platypus were associated with riffle and boulder areas, whereas Iksookimia koreensis, Acheilognathus koreensis, Coreoleuciscus splendidus, Sarcocheilichthys nigripinnis morii, and Odontobutis interrupta were associated with large shallow areas. In contrast, Cyprinus carpio, Carassius auratus, Lepomis macrochirus, and Micropterus salmoides were found at downstream sites associated with large pool areas, sandy/clay-bottomed areas, and vegetated areas. On the basis of these results, we suggest that microhabitat patch types are important in determining the diversity and abundance of fish communities, since a mosaic of different microhabitats supports diverse fish species. As such, microhabitat patches are key components of freshwater stream ecosystem heterogeneity, and a suitable patch composition in stream construction or restoration schemes will support ecologically healthy food webs.

국립공원 특별보호구 정책의 일환인 지리산국립공원 칠선계곡 자연휴식년제 실시에 따른 영향 집단인 지역주민과 탐방객의 다양한 의견을 파악하여 보다 체계적인 국립공원 특별보호구 관리 정책과 공원관리 방안 수립을 위한 기초자료 제공을 목적으로 수행되었다. 이를 위해 칠선계곡 인근 지역인 추성리, 광점동, 의중리, 의탄리, 의평리 등 5개 지역에 거주하고 있는 지역주민과 주변 지역을 방문한 탐방객을 대상으로 편의표본추출(convenience sampling)방식을 이용한 설문조사를 실시하였다. 조사결과, 지역주민과 탐방객 모두 칠선계곡의 자연자원 가치성을 높게 평가하고 있는 것으로 나타나 자연휴식년제의 환경보전 효과는 긍정적인 것으로 판단되나 칠선계곡 자연휴식년제의 관리정책적 적절성과 피해 정도, 지속 여부에 있어서는 상당한 시각 차이를 보였다. 특히 정책적 측면에서의 적절성과 지역사회의 피해 정도에 대한 인식에 있어서는 주진입부에의 입지 여부에 따라 지역주민 간 차이도 통계적으로 유의하게 나타나 자연휴식년제 실시에 대한 이해관계자 간의 상당한 인식의 차이를 보여주었다. 현 단계의 갈등을 최소화하고 자연휴식 년제가 도입된 소기의 성과를 달성하기 위해서는 지역사회와 NGO 등 지역의 이해관계자들과의 원활한 의견협의를 위한 관리주체의 능동적인 자세가 필요하고 이를 반영한 협력적 관리전략의 도출과 수립이 요망된다.
