Ecosystem services (ES) are the benefits that people obtain from ecosystems. Traditional ES assessment methods have focused on the supply of ES, using biophysical data. However, these methods often fail to capture the full value of ES, which is also determined by social and cultural factors. This study proposes a new approach to ES assessment that incorporates socio-cultural perspectives. The study was conducted in Seoul, South Korea. A survey was conducted of 1,805 residents of Seoul to assess their satisfaction with ecosystem services. Exploratory factor analysis was used to identify bundles of ES that were perceived as important by residents. A revised importance-satisfaction analysis was used to calculate the urgency level of each bundle. The results of the study showed that the 21 ES that were considered in the survey could be grouped into three bundles: urban green area-based, biodiversity-based, and resilience-based. The urgency level analysis showed that some bundles were more important than others, and that some bundles were more urgent than others. The findings of this study have several implications. First, they suggest that a socio-cultural approach to ES assessment can provide a more comprehensive and accurate assessment of ES. Second, they show that this approach can be used to identify areas where ES management is most needed. Third, they suggest that this approach could be used to inform ES management and policy decisions.

인간이 생태계로부터 취하는 비물질적인 혜택인 문화서비스에 대한 수요가 최근 국민총소득과 함께 증가하고 있다. 이에 대한 정량적 가치평가를 위해 국내외에서 다수의 연구가 이루어져 왔으나 개인의 사회, 문화적 이질성 등의 주관적 성향과 규모의 차이로 인해 국내 전 지역에 적용하기에는 어려움이 있다. 문화서비스가 발생하기 위해서는 자연생태계와 인간의 접촉이 이루어져야 하며 이러한 관점을 바탕으로 본 연구에서는 접근성이라는 개념을 활용하여 기존 문화서비스 가치평가방법이 가지는 사회, 문화적 주관성을 보완하고자 한다. 국내 전 지역 규모에 적용 가능하며 다양한 이해관계자의 공감대를 형성시킬 수 있는 포괄적인 문화서비스 평가 방법을 제시하는 것이 본 연구의 목적이다. 본 연구에서는 접근성을 근거로 개발된 유럽의 여가 서비스 평가방법 고찰을 통해 국내에 구축된 도로 네트워크와 인구분포현황과 함께 국립생태원에서 수행한 ‘생태자산 간이평가‘ 결과를 활용하여 ’문화서비스 접근성 평가 (CSOS)‘를 남양주시에 시범 적용하였다. 그 결과 남양주시에 산재한 특정 생태자산 및 주거지를 중심으로 우수한 문화서비스 접근성이 존재하는 특정 공간을 도출할 수 있었다. 또한 이를 바탕으로 오늘날 보편적으로 이용되고 있는 SNS 데이터를 활용한 InVEST의 Recreation 평가 모형과 조망점을 활용한 Scenic quality평가 모형간의 차별성과 시범연구로서 가지는 가중치 설정에 대한 한계점을 고찰하였다. A cultural ecosystem service(CES), which is non-material benefit that human gains from ecosystem, has been recently further recognized as gross national income increases. Previous researches proposed to quantify the value of CES, which still remains as a challenging issue today due to its social and cultural subjectivity. This study proposes new way of assessing CES which is called Cultural Service Opportunity Spectrum(CSOS). CSOS is accessibility based CES assessment methodology for regional scale and it is designed to be applicable for any regions in Korea for supporting decision making process. CSOS employed public spatial data which are road network and population density map. In addition, the results of ‘Rapid Assessment of Natural Assets’ implemented by National Institute of Ecology, Korea were used as a complementary data. CSOS was applied to Namyangju-si and the methodology resulted in revealing specific areas with great accessibility to ‘Natural Assets’ in the region. Based on the results, the advantages and limitations of the methodology were discussed with regard to weighting three main factors and in contrast to Scenic Quality model and Recreation model of InVEST which have been commonly used for assessing CES today due to its convenience today.

산림의 CO₂ 흡수량 평가를 위한 통계 및 공간자료의 활용성 검토 - 안산시를 대상으로 -

본 연구는 안산시 산림을 대상으로 연간 CO₂ 흡수량 평가를 위한 통계 및 공간자료의 활용성을 검토하였다. 통계자료, 임상도(1:5,000), 산림수종 표준 탄소흡수량 자료들을 활용해 산림의 연간 CO₂ 흡수량을 산정하였다. 또한 세분류토지피복도를 이용한 연간 CO₂ 흡수량 분석 및 활용성을 검증하였다. 통계자료를 이용한 경우 2010년을 기준으로 연간 CO₂ 흡수량의 차이가 컸다. 이는 2010년부터 산림기본통계의 작성 방법이 고도화됨에 따라 임목축적이 급격히 증가한 결과이다. 향후 통계자료를 활용할 경우 최근의 산림기본통계를 이용한 보정이 필요하다. 임상도(1:5,000)와 산림기본통계(2015, 2010)의 시기 차이를 이용한 방법은 수종들의 생장량에 따른 CO₂ 흡수량이 반영되지 않았다. 산림수종 표준 탄소흡수량 자료와 임상도(1:5,000)를 이용한 결과 연간 42,369 ton을 흡수하였다. 세분류토지피복도와 산림수종 표준 탄소흡수량 자료를 이용한 결과는 40,696 ton이었다. 임상도(1:5,000)를 이용하여 세분류토지피복도를 검증한 결과 p<0.01 수준에서 유의했고, 흡수량 차이는 1,673 ton이었다. 본 연구는 다양한 산림활동의 온실가스 감축 효과 평가에 있어 객관적 기준을 적용하는 일환으로서 의의를 지닌다. 나아가 탄소흡수원과 관련된 토지이용 및 관리 등의 의사결정 지원을 위한 기초자료로 활용이 가능할 것이다. This research was conducted to examine the availability of spatial data for assessing absorption rates of CO₂ in the forest of Ansan-si and evaluate the validity of methods that analyze CO₂ absorption. To statistically assess the CO₂ absorption rates per year, the 1:5,000 Digital Forest- Map (Lim5000) and Standard Carbon Removal of Major Forest Species (SCRMF) methods were employed. Furthermore, Land Cover Map (LCM) was also used to verify CO2 absorption rate availability per year. Great variations in CO₂ absorption rates occurred before and after the year 2010. This was due to improvement in precision and accuracy of the Forest Basic Statistics (FBS) in 2010, which resulted in rapid increase in growing stock. Thus, calibration of data prior to 2010 is necessary, based on recent FBS standards. Previous studies that employed Lim5000 and FBS (2015, 2010) did not take into account the CO₂ absorption rates of different tree species, and the combination of SCRMF and Lim5000 resulted in CO₂ absorption of 42,369 ton. In contrast to the combination of SCRMF and Lim5000, LCM and SCRMF resulted in CO₂ absorption of 40,696 ton. Homoscedasticity tests for Lim5000 and LCM resulted in p-value <0.01, with a difference in CO₂ absorption of 1,673 ton. Given that CO₂ absorption in forests is an important factor that reduces greenhouse gas emissions, the findings of this study should provide fundamental information for supporting a wide range of decision-making processes for land use and management.
