          서식지 적합성 평가를 통한 국립공원 탐방로 관리 방안 연구 - 무등산 국립공원 내 담비 서식지를 중심으로 -

          임치홍,이창석,정성희,박용수,Lim, Chi-Hong,Lee, Chang-Seok,Jung, Song-Hie,Park, Yong-Su 한국환경복원기술학회 2017 한국환경복원기술학회지 Vol.20 No.4

          This study carried out for establishing the synthetic restoration plan to improve ecological quality of Mt. Mudeung National Park based on the results of conservation value assessment for yellow-throated marten habitats. Yellow-throated marten has significant implications as umbrella species for the wildlife habitats conservation, therefore, this species could be used to ecological restoration plan of the damaged forest ecosystem in Mt. Mudeung National Park. In this study, we diagnosed the quality of yellow-throated marten habitats in Mt. Mudeung National Park based on five natural and two artificial factors. In addition, we evaluated the integrity of each zone divided by trails quantitatively based on land use intensity. As a result, forest landscape quality in Mt. Mudeung National Park was influenced greatly by human activity and the degree was depended on the intensity of trails. Therefore, in this study, we suggested the closing of trails composed of the illegal and 36 legal trails. And then, we modeled the changes of habitats quality of Yellow-throated marten for each closing step. As a result the area of core habitats increased by two times and wildlife habitats quality improved in the whole area of the Mt. Mudeung National Park. As a result, the results of this study indicate that man-made linear landscape elements play a key role in the quality of habitats for predators, which require large habitats area like the Yellow-throated marten. Therefore, in order to establish an ecological restoration plan in the mountainous area, we recommend the concept of the linear landscape should be applied with the concept of area landscape.

          생태적 진단결과에 기초한 창원천과 남천의 복원계획

          안지홍,임치홍,정성희,김아름,우동민,이창석,An, Ji Hong,Lim, Chi Hong,Jung, Song Hie,Kim, A Reum,Woo, Dong Min,Lee, Chang Seok 한국물환경학회 2017 한국물환경학회지 Vol.33 No.5

          This study was carried out for the purpose of creating a restoration plan to improve the ecological quality of the Changwon and Nam streams. Based upon the results of comprehensive diagnostic assessment, restoration priority was given to the upstream reach, where conservation status is relatively superior. Restoration level was usually determined to practice active restoration as conservation, and the states of both Changwon and Nam streams were not so good. Restoration plans, by reach, were classified into "upstream", "midstream", and "downstream" were suggested in both terms of horizontal section frame and vegetation-based on the result of diagnostic assessment and the reference information. "Upstream", "mid-stream" and the "downstream" of Changwon and Nam streams were classified into "small-gravel- mountainous", "small-sand-plain", and "small-clay-plain streams" respectively (based on scale, and substrate and slope of river bed). The spatial arrangement of vegetation was laid out in diagram form by reflecting micro-topography and the water level of the horizontal section of river. Information regarding species composition was recommended as dominant species, which appear frequently in three vegetation zones composed of herbaceous plants, shrubs and trees and sub-tree- dominated zones divided by reflecting disturbance regime, depending on position on the horizontal section of river. Moreover, there have been prepared not only plans to improve the terrestrial ecosystems around the streams but also plans to create ecological networks, which can serve to improve the ecologic quality of the whole regional environment by serving to connect streams and terrestrial ecosystems, a process probably necessary and definitely recommended to realize true (genuine) restoration. Plans for ecological parks and networks were prepared by mimicking the species composition of Alnus japanica community, Zelkova serrata community, Carpinus laxiflora community, Quercus aliena community, and Q. serrata community.

          In order to improve water quality in the Paldang Lake, a riparian vegetation belt, treatment wetland, and artificial floating island were designed for introduction in the upland field, the estuary of tributaries, and the section of water facing mountainous land, respectively. We synthesized vegetation information collected from a reference river and found that herbaceous, shrubby, and tree vegetation zones tended to be dominated by Phragmites japonica, Phalaris arundinacea, etc.; Salix gracilistyla, S. integra, etc.; and S. koreensis, S. subfragilis, and Morus alba, respectively. In our plan, the herbaceous vegetation zone, which is established on floodplains with a high frequency of disturbance, will be left in its natural state. A shrubby vegetation zone will be created by imitating the species composition of the reference river in the ecotone between floodplain and embankment. A tree vegetation zone will be created by imitating species composition on the embankment slope. In the treatment wetland, we plan to create emerged and softwood plant zones by imitating the species composition of the Zizania latifolia community, the Typha orientalis community, the P. communis community, the S. integra community, and the S. koreensis community. The floating island will be created by restoring Z. latifolia and T. orientalis for water purification purposes.

          Since Gyungan stream is included in the protected zone of the water supply source of the Metropolitan area in Korea, the water quality needs to be continuously managed. Therefore, a measure is required that can inhibit the flow of water pollutant into the water body and facilitate the ecological restoration of riparian vegetation. A field survey was conducted on the hydrological characteristics of the landscape elements established on the downstream catchment of the Gyungan stream, the result of which showed that the paddy field and urbanized area can be regarded as point pollution sources. The upland field can be regarded as a non-point pollution source. In order to improve the water quality in the Paldang lake, we first recommended creating a riparian vegetation belt. We also suggested introducing a treatment wetland and an artificial plant island to places in which the creation of a riparian vegetation belt is not ensured. We recommend creating a treatment wetland equipped with diverse functional groups. For creating the plant island, we recommend Zizania latifolia and Typha orientalis, which showed the highest productivity among aquatic plants. The former could be introduced around the outlet of a paddy field and the estuary of tributaries, while the latter could be introduced to a water body directly sourced from mountainous land.

          A landcover map watershed of downstream reach in the Gyungan stream was made by using the existing land use map and interpreting satellite images and aerial photos. Based on the map, we analyzed land use patterns of this basin. Broad-leaved forest occupied the largest area among landscape elements established in this watershed. The total area of the zone designated as the waterside district by the central government was 4.7 km2, and broad-leaved forest occupied the largest area as 33.9% in this zone. Therefore, the area did not meet the qualifications of riparian zones. Riparian vegetation established in the Gyungan stream watershed was composed of Phragmites communis, Miscanthus sacchariflorus, Salix gracilistyla, Salix koreensis. But terrestrial vegetation elements such as Ambrosia trifida, Ailanthus altissima, Robinia pseudoacacia also appeared in this area. On the other hand, Phragmites japonica, Salix gracilistyla, Salix koreensis, Salix integra, Ulmus davidiana and so on appeared in the riparian zone the reference streams. Differently from the vegetation established on the reference streams, terrestrial vegetation elements appeared frequently in the Gyungan stream watershed. This result would be due to that the Gyungan stream watershed is exposed to excessive human interferences.

          창원천과 남천의 생태적 복원을 위한 식생 측면의 진단평가

          안지홍 ( Ji Hong An ),임치홍 ( Chi Hong Lim ),정성희 ( Song Hie Jung ),김아름 ( A Reum Kim ),우동민 ( Dong Min Woo ),이창석 ( Chang Seok Lee ) 한국물환경학회(구 한국수질보전학회) 2016 한국물환경학회지 Vol.32 No.5

          The Changwon and Nam streams that run through the Changwon city were evaluated based on longitudinal and horizontal configurations and vegetation state in order to prepare a restoration plan. Riparian vegetation of the Changwon and Nam streams are normally dominated by herbaceous plants. However, the woody plants, Salix pseudolasiogyne, Rubus parvifolius, Salix koreensis, Robinia pseudoacacia,and Amorpha fruticosa have appeared. Planting to introduce various types of plants for landscape architecture has also been observed. Evaluation of naturalness based on the vegetation state of both Changwon and Nam streams showed very low naturalness of degree 1 or 2, with the exception of a few reaches of the upstream sector. In these few reaches of the upstream sector, Salix koreensis and Salix chaenomeloides showed heights at the subtree level, however, they were located at the position of shrubland close to the waterway. These reaches were, therefore, evaluated as degree 3 rather than degree 4 in naturalness. The result of diagnostic evaluation classified by reach indicated the requirement for active restoration, such as transformation of the channelized stream into a meandering one and a step-type cross section into a pool-type one, introduction of vegetation suitable to the region and site, and creation of an ecological network between the stream and the surrounding terrestrial ecosystems.

        • 제1분과 : 보호지역 관리 ; 계룡산국립공원의 외래식물 분포 현황

          명현호 ( Hyeon Ho Myung ),임치홍 ( Chi Hong Lim ),이선미 ( Seon Mi Lee ) 한국환경생태학회 2015 한국환경생태학회 학술대회지 Vol.2015 No.1

          외래식물은 다양한 경로를 통해 유입되고 있으며, 1990년대 후반부터 도시화의 확대로 인해 외래식물의 종수 및 분포면적이 가파르게 증가하고 있다. 인위적인 교란이 빈번히 일어나는 곳을 중심으로 분포 및 확산되고 있으며, 생태계가 건강하다고 할 수 있는 국립공원에서도 탐방로, 주차장, 도로 및 나지 등 교란이 잦은 곳에 분포하며 그로 인한 문제가 발생하고 있다. 따라서 2008년부터 각 국립공원에서 생태계교란야생식물 제거사업을 실시하고 있으며, 제거면적은 매년 증가하고 있다. 본 연구의 목적은 인위적 교란이 많이 발생하는 도심형 국립공원인 계룡산국립공원을 대상으로 외래식물의 정확한 분포 현황을 파악하여 효과적인 관리 방안을 마련하기 위한 기초 자료를 확보하는 것이다. 2014년 8월부터 10월까지 계룡산국립공원의 17개 구간을 대상으로 공원 내 및 경계 지역에 출현하는 모든 외래식물을 조사하고 분포지점의 GPS 좌표를 수집한 후 분포도롤 작성하였다. 그 결과 총 19과 19속 55종 1변종으로 총 56분류군을 확인하였고 이중 생태계교란야생식물은 돼지풀, 단풍잎돼지풀, 미국쑥부쟁이, 가시상추로 총 4분류군이었다. 외래식물은 주로 주차장, 나지, 폐경작지, 저수지, 탐방로 및 도로, 사찰 주변 등 인위적 교란이 많은 지역에 분포하였고, 대부분 탐방로 및 도로 주변에 점형으로 분포하였으며, 나지와 폐경작지 등에서 면형으로 분포하였다. 종별 출현빈도를 분석한 결과, 돼지풀이 326회로 가장 많았고 그 다음으로 개망초 291회, 달맞이꽃 180회, 망초 176회, 미국쑥부쟁이 153회 로 나타났다. 한편 갓, 도꼬마리, 미국까마중, 서양톱풀, 선토끼풀, 오리새, 큰개불알풀, 큰조아재비는 1회로 가장 적게 출현하였다. 고도별 분포 현황을 분석한 결과, 대부분 350m 이하의 저지대에 분포하였으며(93.8%), 350m에서 500m 사이에 2.1%, 500m 이상에서 4.1% 분포하였다. 빛투과량이 많고 인위적 간섭이 많은 탐방로 입구 주변에서 출현 빈도가 매우 높았고 숲 속을 관통하여 빛투과량이 낮은 탐방로에서는 거의 출현하지 않다가 다시 빛투과량이 높아지는 산 정상부에서 출현 횟수가 증가하였다. 구간별 분포 현황을 분석한 결과, 만학골 코스에서 총 29분류군으로 가장 많은 외래식물이 출현하였고, 그 다음으로 갑사코스에서 27분류군이 출현하였으며 수통골 코스에서 가장적은 2분류군이 출현하였다. 개망초는 전 구간에서 출현하였고, 달맞이꽃과 망초가 16개 구간에서 출현하였다. 본 연구 결과 탐방로 및 도로와 같은 선형 요소는 외래식물 확산의 주요 통로이고 나지 및 공터와 같은 면형 요소는 주요 확산원인 것으로 판단된다. 현재로서는 물리적인제거 방법이 가장 효과적이며, 선형 요소 주변에 분포하는 외래식물은 완전히 제거하기 어려우므로 위해성이 높고 확산 속도가 빠른 종을 우선적으로 선정하여 개화 및 결실전 지속적인 물리적 제거 작업을 실시해야 한다. 면형 요소에 분포하는 외래식물은 면적이 넓은 곳을 우선적으로 식생복원을 실시하면 분포 면적이 감소할 것으로 판단된다. 한편 본 연구는 늦여름부터 가을까지 조사한 결과이므로 봄철 및 여름철 조사를 실시하면 더 많은 종류의 외래식물이 분포할 것으로 예상되며 국립공원 내 외래식물의 종합적 관리방안 마련을 위해서는 계절별 조사를 실시해야 한다. 정확한 분포 현황을 조사한 후 구체적인 관리 방안을 제시해야하고, 주기적인 모니터링을 통해 가능한 한 확산되기 전의 침입 초기에 외래식물의 확산을 차단하는 것이 가장 효과적이다. 또한 구체적인 관리 방안 마련 및 생태적 정보를 획득하기 위한 다양한 실험연구가 필요하다. 이렇게 수집한 정보를 바탕으로 추후 위해성이 높은 우선관리종을 선정하고 생태적으로 미치는 위험성이 높은 지역을 우선관리지역으로 지정하여 종 및 지역에 대한 관리 방안을 마련해야 한다.

          서울의 두 도시 근린공원에서 평가된 탄소수지

          김경순 ( Kim Gyung Soon ),피정훈 ( Jung Hun Pi ),안지홍 ( Ji Hong An ),임치홍 ( Chi Hong Lim ),정성희 ( Song Hie Jung ),주승진 ( Seung Jin Joo ),이창석 ( Chang Seok Lee ) 한국하천호수학회(구 한국육수학회) 2016 생태와 환경 Vol.49 No.1

          본 연구는 서울시 노원구에 위치한 두 도시공원 (노해근린공원, 상계근린공원)의 탄소수지를 정량하고 인접한 자연공원인 불암산 신갈나무림을 대상으로 동일한 조사를 수행하여 그 개선방안을 찾기 위해 수행하였다. 순생산량(NPP)은 상대생장법을 적용하여 측정하였고, 토양호흡량은 EGM-4를 이용하여 측정하였다. 노해근린공원과 상계근린공원에 조성된 식생의 순생산량은 각각 5.4 ton C ha<sup>-1</sup> yr<sup>-1</sup>와 4.8 ton C ha<sup>-1</sup> yr<sup>-1</sup>로 나타났고, 불암산 신갈나무군락의 순생산량은 6.3 ton C ha<sup>-1</sup> yr<sup>-1</sup>로 나타났다. 연간 종속영양생물 토양호흡량은 노해근린공원과 상계근린공원에서 각각 5.3 ton C ha<sup>-1</sup> yr<sup>-1</sup>와 3.4 ton C ha<sup>-1</sup> yr<sup>-1</sup>로 측정되었고, 불암산 신갈나무군락의 토양호흡량은 4.1 ton C ha<sup>-1</sup> yr<sup>-1</sup>로 측정되었다. 공원구역에서 나지가 차지하는 면적을 반영하여 산정한 노해근린공원과 상계근린공원의 순생태계생산량은 각각 - 1.0 ton C ha<sup>-1</sup> yr<sup>-1</sup>와 0.6 ton C ha<sup>-1</sup> yr<sup>-1</sup>로 나타났고, 불암산 신갈나무군락의 순생태계생산량은 2.3 ton C ha<sup>-1</sup> yr<sup>-1</sup>로 나타났다. 순생태계생산량 정보에 근거하면 노해근린공원은 탄소배출원으로 분류되었다. 반면에 상계근린공원은 탄소흡수원으로 구분되었지만 그 역할은 자연식생과 비교해 크게 낮은 것으로 평가되었다. 도시공원의 낮은 순생태계생산량은 자연림과 비교해 낮은 순생산량과 탄소배출 기능이 있는 나지를 넓게 배정한 것에 기인하는 것으로 나타났다. This study was carried out to assess the carbon budget of two urban parks and one natural park and to prepare the plan for improving the ecological functions of the park including carbon sink. Net Ecosystem Production (NEP) of those study sites was calculated from the relationship between Net Primary Production (NPP) and soil respiration of each study site. To understand carbon budget of the whole area designated as the park, carbon budget of the urban park was analyzed by classifying the vegetated and the non-vegetated zones. NEP of the Nohae and the Sanggye parks calculated by reflecting areal size that the non-vegetated zones occupy were shown in - 1.0 and 0.6 tonCha<sup>-1</sup> yr<sup>-1</sup>, respectively. On the other hand, NEP of Mt. Bulam natural park as a reference site was in 2.3 ton C ha<sup>-1</sup> yr<sup>-1</sup>. Based on the result, the Nohae park was assessed as carbon source rather than carbon sink. On the other hand, the Sanggye park was classified as carbon sink but the role was poor compared with natural park. The result is, first of all, due to lower NPP of the vegetation introduced for the parks compared with natural vegetation. The other reason is due to wide arrangement of non-vegetated zone. To solve those problems and thereby to create the urban park with high ecological quality, selection of plant species suitable for the ecological characteristic of the park, their arrangement imitated natural vegetation, and ecological zoning were recommended.
