  • This study has intended to build a rural landscape evaluation model based on an integrated landscape assessment paradigm of rural region using an additive integration index method and applied the model to the Seondong Region of Gochang-gun, Jeollabuk-do, Korea. To reach this goal, this study developed a model to calculate Integrated Landscape Assessment Index. The model has employed the Objective Landscape Index, the Subjective Landscape Index, and the weighted values, and was applied to the Seondong region. This study has found the following results: 1) forests and water spaces were assessed with relatively better visual preferences and better landscape ecosystem; 2) the historic cultural area and scenic agriculture as well as general farm land were assessed with moderate ratings; and, 3) the villages included in development plan, their adjacent arable farming land, and the village watercourses were forming relatively poorer landscape.

  • This study was conducted to understand the community characteristics of benthic macroinvertebrates according to Growth Environment at 6 Palustrine Wetlands in a rural area. As growth environment factors, size, water depth, water inlet and water outlet, land-use and water environment was analyzed. Two years' quantitative collection of benthic macroinvertebrate was carried out, and it executed community analysis and ESB index calculation and also carried out twinspan, MDS and correlation analysis. As a result, the collected benthic macroinvertebrate was 1254 individuals with 3 Phylums, 6 Classes, 14 Orders, 35 Families, 52 Genera and 61 Species. Odonata and Coenagreionidae had the highest species and individuals. Dominance Index was 0.252~0.698, Diversity Index was 1.661~2.902, Evenness Index was 0.414~0.724, and Species Richness Index was 1.990~6.224. As a result of community analysis, when correlation analysis was executed, Dominance Index had the opposite tendency with Diversity Index and Evenness Index, which had the same tendency with the previous studies. When ESB Index was calculated, Grade 2 (polluted) had the highest species with 48 species (78.7%). It is determined from the Environmental quality evaluation and saprobity evaluation result according to ESB index that there is a need to revise environmental evaluation system more specifically. As a result of MDS analysis, the subject spots A and D had the highest similarity, and the subject spot E and D had a relatively high similarity. The life environment that is the closest related with species diversity is estimated by the land-use. As for number of Individual, it seems to have the closest relation with inlet, which is to be determined as a characteristics of Palustrine Wetland. Through such investigation, this study is expected to be utilized for various types of habitats including ecological pond and to be utilized for the increase of species diversity in rural areas.

  • This paper describes the study methods of identifying forest vegetation types, based on this study, forest vegetation classification method based on vegetation index is proposed. According to reflectance data of vegetation canopy and soil line equation NIR=1.506R+0.0076 in Jingyuetan, Changchun, China, many vegetation index are calculated and analyzed. The relationships between vegetation index and vegetation types are that PVI identifies broadleaf forest and conifer forest the most easily, the next is TSAVI and MSAVI, but their calculation is complex. RVI values of different conifer trees vary obviously, so RVI can classify conifer trees. In a word, combination of PVI and RVI is evaluated to classify different vegetation types.

  • Eight years (2014-2021) of climate data were collected from an automatic weather observation system installed at the foot of Mt. Geumo in Chilgok, Gyeongbuk. Using these data, we investigated local bio-climatological indices (warmth index, WI; coldness index, CI; and effective accumulated temperature, EAT) of the mountain region adjacent to the Keimyung Dongyeong forest. The study area's WI and CI were 109.3℃ and -11.3℃ per month, respectively, averaged across 8 years. These values are indicative of an evergreen broad-leaved forest in the warm temperate climate zone, suitable for cultivating sweet persimmons and figs. Additionally, EAT in Dongyeong was 2,113.7℃, averaged across 8 years, suitable for growing crops such as corn, soybean, and potato.

  • Purpose: This study aims to determine the effect of economic agents, such as the amount of government expenditure on the environment, households, manufacturing industry, and shipping activities; on environmental degradation in Indonesia. Research design, data, and methodology: This study is conducted with 264 observations from panel data of 33 provinces during 2010-2017. Environmental degradation is measured by using the environmental quality index collected from Indonesian Ministry of Forestry and Indonesian Central Bureau of Statistics. Three testing models are used to test the panel data, namely Common Effect Model (CEM), Fixed Effect Model (FEM), and Random Effect Model (REM). Results: The research findings show that the amount of government expenditure on the environment, households, and shipping activities have a negative and significant effects on environmental degradation, while the number of manufacturing industry has positive and significant effect on environmental degradation. Unlike the previous studies, the result also shows that government expenditure on environmental has a positive and significant effect on environmental quality index. Conclusion: It can be concluded that even though Indonesian government spent a low budget on environment, their environmental regulation has succeeded both in reducing environmental degradation and increasing the environmental quality as indicated by Indonesian environmental quality index.

  • Air quality index (AQI) or air pollution index (API) is commonly used to report the level of severity of air pollution to public. A number of methods were developed in the past by various researchers/environmental agencies for determination of AQI or API but there is no universally accepted method exists, which is appropriate for all situations. Different method uses different aggregation function in calculating AQI or API and also considers different types and numbers of pollutants. The intended uses of AQI or API are to identify the poor air quality zones and public reporting for severity of exposure of poor air quality. Most of the AQI or API indices can be broadly classify as single pollutant index or multi-pollutant index with different aggregation method. Every indexing method has its own characteristic strengths and weaknesses that affect its suitability for particular applications. This paper attempt to present a review of all the major air quality indices developed worldwide.

  • 본 연구는 2010년 세계경제포럼에서 발표된 환경성과지수(EPI) 데이터를 활용하여 국가별 환경지표 비교와 유사성분석을 하였다. 환경지표에 대한 비교분석은 환경성과지수 대상국인 163개국을 4개의 소득집단으로 나누어 분석을 하였으며, 유사성분석은 OECD 30개국을 대상으로 환경보건부문과 생태건전성부문으로 PREFMAP에 나타내었다. 먼저 비교분석의 결과를 보면 국가 소득에 따라 대부분의 환경지표 차이가 있었으며, 본 논문에서는 소득그룹별 차이를 보인 변수들만 제시하였다. 다음으로 환경정책지표별 유사성분석을 통하여 OECD국가별 환경정책지표별 위치를 하나의 인지도에 나타냄으로써 다른 선진 국가들과 비교하여 취약점을 파악하였다. 이는 향후 환경관련정책수립 시 나아갈 방향을 설정하는데 있어서 유용할 것이라 사료된다. 하지만 본 연구에 있어서 시계열적 자료를 확보하여 환경관련변수별 시간적 변화를 살펴보는 것이 더욱 가치 있는 연구가 되었을 것으로 판단되나 EPI가 2002년 처음 발표된 이후 지금까지 총 4차례에 걸쳐 발표되어 실시하지 못한 점에 아쉬움이 있다. 그러나 이 한계점은 향후 시간이 흘러 데이터가 확보되어 더욱 발전된 연구가 이루어지길 바란다.

  • 관광단지 개발사업은 자연환경이 양호하고 경관이 우수한 지역을 대상으로 추진됨에 따라 주변 지역에 대한 환경부하를 지나치게 가중하는 점이 문제로 제시된 바 있다. 이에 본 연구에서는 2012년~2021년간 이루어진 국내 관광단지 개발사업의 환경영향평가 결과를 토대로 동 사업으로 야기되는 환경영향을 파악하였다. 특히 다양한 환경영향을 종합적·정량적으로 분석하고자 선행연구를 통해 마련된 EA-INDEX를 관광단지의 사업 특성에 적합하게 신규 도출하였으며, 이를 통해 관광단지 개발사업의 환경영향을 크게 자연환경 보전, 자원 보존, 생활환경 보호 부문으로 구분하여 각 세부 지표별로 살펴보았다. 그 결과 지난 10년간 국내 관광단지 개발사업은 친환경성이 증가하는 방향으로 추진·개발된 것으로 나타났으며, 특히 자연환경 보전 부문에서 그 증가 추세가 뚜렷함이 확인되었다. 반면 자원 보존 부문의 경우 친환경성이 감소하는 것으로 확인되었으므로 추후 신규 개발계획 수립 시 이를 제고할 수 있는 노력하는 것이 필요할 것으로 판단된다. 본 연구는 비교적 장기간에 걸친 관광단지 개발사업에 대한 환경적 영향을 파악하고, 특히 개발사업의 친환경성에 대해 각 세부 부문별 영향을 정량적으로 분석한 것에 의의가 있는 것으로 판단된다. 추후 개발사업과 관련한 정책 이벤트, 연관 사회적 이슈 등의 정보를 종합한 분석이 이뤄진다면, EA-INDEX를 활용한 개발사업의 경향 파악에 더욱 폭넓은 해설이 가능할 것으로 기대된다.
