국내 하수처리장의 수질기준이 강화되고 하수처리량이 지속적으로 증가하면서 하수처리장이 수용할 수 있는 처리용량의 한계와 이에 따른 관리 비용이 급격하게 증가하고 있다. 이러한 문제들을 개선하기 위한 다양한 방법들이 시도되고 있으나, 열악한 하수 환경과 높은 처리 비용 등으로 인하여 많은 어려움을 겪고 있는 것이 현실이다. 본 논문에서는 하수처리장으로 유입되는 하수를 오염도에 따라 하수량을 제어함으로서 하수처리장으로 유입되는 부하를 경감하여 하수 처리 비용을 줄이고, 환경 오염을 최소화 할 수 있는 친환경 하천 생태계 보존을 위한 IoT 기반 하수정보화 플랫폼을 제안하고자 한다.

As important ecological systems, wetlands contribute a wide array of biological, social. and economic benefits. However, wetlands are lost until the present, primarily due to human induced land-use conversions. Society is placing demands for the efficient preservation and management on Woopo wetland as the first largest wetland in Korea. GIS(Geographic Information System) is a rapidly developing technology for handling, analyzing, and modeling ecological information on wetlands. In the paper, Woopo Wetland Management System has been developed by using Desktop GIS and Internet GIS technology to embrace major functions: information query and browsing, spatial searching on map, and rule-based analysis. As a menu-driven system, these functions are designed to be implemented through customized menus. The developed system is expected to be used for the effective publicity service as well as the professional management of Woopo.

인간은 생태계로부터 다양한 공익적 기능을 제공받고 있지만 시설원예단지 조성은 불투수면적 확장과 생물서식처 손실로 인해 기능저하의 원인이 될 수 있다. 시설원예단지 조성이 식물 종 다양성에 미치는 영향을 파악하였다. 식생분포 특성 분석결과 논에 비해 시설원예단지의 식물다양성이 상당히 낮다는 것을 알 수 있었다. 따라서 저 영향개발, 서식공간 배치, 식물 보전, 화학비료 사용제한, 서식처 조성, 보전비용 등을 제안하였다. 생활형 분석을 통해 일년생식물과 수생식물의 생육기반 환경 조성을 제시하였다. 귀화식물은 총 10과 20종류가 확인되었으며, 귀화율은 유리온실과 연동형 온실이 매우 높게 분석되어 콘크리트 피복을 지양하고 자연토양 피복을 유도 할 것을 제안하였다. 연구결과는 통계분석을 통해 확인하고 불투수면적을 자연형 토양으로 전환을 제안하였다. 본 연구결과는 지속가능한 농업경관 유지와 대규모 간척지 개발 사업에 있어 친환경, 생태적 시설원예단지 조성을 위한 정책자료에 활용되길 기대한다.

본 연구는 최근 자연체험형 여가휴양 공간으로 이용이 커지고 있는 도시자연공원 탐방로의 분포와 훼손특성을 파악하여 향후 자연보전형 탐방로 정비의 방향을 설정하기 위한 기초 자료 제시를 목적으로 수행하였다. 연구대상지는 계양공원, 백마공원, 약사공원, 문학공원, 청 량공원이었다. 이들 공원은 인천시 남북녹지축에 위치하여 도시생태계 보전의 핵심지역이 되고 있는 산지형 도시자연공원이며 등반형 탐방이 많이 일어나는 곳이다. 주 탐방 노선수는 계양공원 42개, 백마공원 43개, 약사공원 9개, 문학공원 28개, 청량공원 22개로서 면적에 비해 과도한 탐방로가 있었으며 샛길이 늘어나고 있는 것으로 추측되었다. 연구대상지 탐방로의 평균 나지노폭은 3.5m, 평균 최대침식 깊이는 21.3cm로 나타났고 체계적인 정비가 없을 경우 훼손은 급격히 증가될 것으로 판단되었다. 훼손이 심해 복구가 요구되는 산림환경피해도 등급 5, 6등급의 비율은 19.6∼78.0%에 달했다. 연구결과에 기초하여 인천 남북녹지축상의 산지형 도시자연공원 탐방로의 정비와 관리방안을 제안하였다.

필리핀은 친환경자원을 유지하고 시민들에게 서비스 및 필수품을 제공할 수 있는 수자원이 풍부한 열도이다. 지역 사회가 필요로 하는 물과 식량을 제공하는 일부 수역은 자국 내 자연습지로 선정된다. 본 연구에서는 '국제적으로 중요한 습지'로 선정된 Naujan Lake National Park, Agusan Marsh Wildlife Sanctuary, Olango Island Wildlife Sanctuary, Tubbataha Reefs Natural Park, Las $Pi{\tilde{n}}as-Para{\tilde{n}}aque$ Critical Habitat and Ecotourism Area and Puerto Princesa Subterranean River National Park의 6개 지역을 포함한 총 65개의 습지를 조사하였다. 이들 습지는 22개의 유형으로 분류되었다. 필리핀 습지는 현재 습지의 전용, 자원의 남용, 생활 및 산업과 농업활동에 따른 오염, 그리고 기후변화와 같은 수많은 위협에 직면해있다. 본 논문은 습지의 특성 및 구성요소, 생태계에 미치는 영향, 습지가 직면한 위기에 대한 개관을 제공한다. 또한 정부와 민간기관에서 시행하고 있는 습지 보존 대책이 토의되고 평가되었다. 습지에 대한 지자체 및 국가차원의 법령이 부족한 것으로 판단되었으며, 이는 습지의 질적 하락으로 이어진다. 이러한 습지의 보존 및 활용은 필리핀 전체 지역사회의 자발적인 참여로부터 극대화될 수 있다.

The purpose of this study was to propose an ecological management plan by the comprehensive analysis of biotope structures on Namsan Urban Natural Park in Seoul. Classified by actual vegetation, structure of layer and vegetation damage, biotope structures were composed of forest area, compact management area, herb area, cultivated area and non-ecology(urban) area. Succession had seened to stop in the Native forest. Artifical forest was divided into two types. The first, upper layer, was too dense to accommodate lower layer plants, the other case was the appearance of Quercus spp. and the first stage plants of succession following the declination of the upper layer plants. The soil pH of Nam-san Urban Park was 4.21∼4.51, which meant the soil was becoming acid. As the result of acidity, leaching of available nutrition(K/sup +/, NH₄/sup +/, Ca/sup ++/ etc.) was immediately influenced by the natural ecosystem, influence of acid rain was disturbed to becoming organic matter which was use to plants. In the case of a biotope structure management plan, the urban area was prohibited to spread outside. Cultivated and herb area was regenerated to natural forest. In the forest area, the compact management area was maintained with its present condition, and then it is desirable to make a preservation area and to plant shrubs. Planted Pinus densiflora Community was needed to eliminate competitive species of canopy layer, and plant shrubs. Management of deciduous broad-leaved Comm. was maintained in its present conditionand it is desirable to raise the diversity of the understory and shrub layer. The management of the artifical forest seems to be suitable for Q. spp. community. The care of naturalized plants prevents the expansion and restores the structure of wild plants. The soil management was a marked restoration soil ecosystem in order to prevent soil acid and drying.

The naturalized plants in this site were 13 families, 31 genera, 36 species, 2 varieties, 38 taxa and naturalization rate was 9.0% of all 422 taxa vascular plants. Because of recent rapid increase of cars and people around here, analysis shows many naturalized plants and high naturalized ratio. And wild plants disturbing ecosystem like Ambrosia artemisiifolia var. elatior have been increasing. So, it needs continuing control and conservation measures on the plant ecosystem.

Under Korea's Enforcement Decree of the Framework Act on Environmental Policy amended in 2013, total organic carbon (TOC) is newly added as water quality parameter to assess organic pollution in water and aquatic ecosystem. To meet the TOC requirement and improve quality of effluent discharged into public watershed, it is also necessary to develop standards for TOC in effluent from public sewage treatment works (PSTWs). In this study, we reviewed the characteristics and removal efficiency of TOC in influent and effluent of PSTWs. The study found that phosphorus treatment process removed not only soluble phosphorus but also a portion of TOC remaining after the secondary treatment process. TOC concentration in effluent from PSTWs operated in tandem with industrial wastewater treatment work was higher due to influx of insoluble substances from the industrial wastewater treatment work. In order to lay a foundation for the management of TOC from PSTWs, it is necessary to carry out research on TOC from different perspectives. For example, studies on the generation mechanism of TOC and the impact of TOC on drinking water resources, assessment of effluent qualities through monitoring, and development of measures to control TOC for the preservation of aquatic ecosystem are needed.
