윤광성(Kwang Sung Yun) 한국지역지리학회 2007 한국지역지리학회지 Vol.13 No.2
본 연구의 목적은 휴경 연차에 따른 논토양의 물리·화학적 특성과 식생의 변화를 분석함으로써 묵논의 습지 생태계로서의 가치와 다양한 생물 서식처로서의 기능에 적합한지를 평가하는 것이다. 본 연구의 물리·화학적 특성과 식생 천이과정, 그리고 묵논 습지로서의 기능적 가치 분석 결과를 요약하면 다음과 같다. 첫째, 휴경 연수가 증가 할수록 표토가 조립화 되는 경향으로 나타났다. 둘째, 휴경 연수에 따라 유기물과 유효인산, 칼슘의 함량이 차이가 나타났으며, 칼륨과 마그네슘, CEC는 크게 변화지 않는 것으로 분석되었다. 셋째, 식생 천이과정의 단계별로 식물종 구성비를 보면, 출현종수는 초기에 14종에서 중기로 갈수록 증가하고 후기로 가면 다시 줄어드는 것으로 나타났다. 식물 조사 지소별 종구성적 조합에 의한 유사도 분석 결과를 보면 크게 천이단계별로 3그룹으로 분류되어 나타났다. 천이 초기는 댓골 상단, 하단이 중기 단계는 논방골 1단, 2단, 3단이, 천이 후기는 논방골 4단, 5단으로 그룹화 되었다. 넷째, 환경부 습지기능평가표와 RAM을 기준으로 논방골 묵논 습지에 대한 기능가치분석을 실시 한 결과 전체 가치평균이 2.13으로 "보통"에 해당하는 것으로 나타났다. The Purpose of this study is to evaluate the value of abandoned paddy fields as wetland ecosystems and their suitability as habitats for various species. Physical and chemical characteristics of soils and the change of vegetation in paddy fields were analysed with the passage of time after cease of cultivation. The results of analyses for soil characteristics, vegetation succession, and functional values of abandoned paddy fields as wetlands were as follows: First, top soils become coarser as years after abandonment increase. Second, as the years of abandonment passed, there were significant differences in organic matter, available phosphorate and calcium, while not in magnesium and cation exchange capacity(CEC). Third, species increased from early stage till middle stage, and decreased in late stage. In similarity analysis of species composition, sites were classified into three groups according to the stage of succession. Upper and lower terraces at Daetgol were classified as early stage of succession. The 1st, 2nd and 3rd terraces at Nonbanggol were in middle stage, while the 4th and 5th were in late stage. Forth, according to evaluation sheets of MoE and RAM(Rapid Assessment Method) standards, the overall average of functional value of Nonbanggol site were 2.13, classified as "common".

제3차 전국자연환경조사 지형분야 등급부여체계의 적정성과 개선방안
윤광성 ( Kwang Sung Yun ),신영호 ( Young Ho Shin ) 한국지형학회 2015 한국지형학회지 Vol.22 No.1
In this study, we examined characteristics of grade evaluation system of geomorphology part in the 3rd Natural Environment Survey by analyzing its performed data and derived improvement of grade evaluation system which secures appropriateness and objectivity. We regard that grade evaluation system has not enough appropriateness and objectivity, although output of geomorphology part contribute various deals to academic communities and general public. There were several problems; unequaled ratio between high grade and low grade, biased evaluation in some evaluation factors, redundancy between evaluation factors, and deviation of importance values between evaluation factors by geomorphic groups and surveyors respectively. To overcome these problems, we proposed an improvement scheme of geomorphic grade evaluation system, which is focused to point-based grading method, subdividing evaluation factors, avoidance from redundancy by detailed guideline, intuitive and objective grading and so on. The proposed improvement scheme will be a touchstone of related discussion in geomorphologic group and be make progress into more appropriate and objective one by a wide-ranging discussion.

제3차 전국자연환경조사 지형분야의 성과와제4차 조사의 특징 및 발전방향 제시
윤광성 ( Kwang Sung Yun ),오인순 ( In Sun Oh ),강지현 ( Ji Hyun Kang ),이재호 ( Jae Ho Lee ),김성환 ( Sung Hwan Kim ) 한국지형학회 2014 한국지형학회지 Vol.21 No.3
“Natural Environment Survey” is the law-bound, nationwide-scaled, multidisciplinary project that has been executed by the Ministry of Environment(MOE) since 1988. The purpose of the project is to identify and map the natural resources worthy of conservation, including landform, wild plants and animals. The 2nd and the 3rd Natural Environment Survey (1997-2012) made it possible to release the first version of National Maps of Ecosystem and Nature in 2007, and to update the information on mapped natural resources and to identify the new ones for including the next version of the Maps in 2013. This article aims to introduce the main achievement of the 3rd survey and the main direction of the 4th survey from a geomorphological perspective. Through the 3rd Survey, 17,076 geomorphological resources have been found and 6,530 of them have been classified as the resources necessary for protection and conservation. The 4th Survey has adopted the boundary of geomorphological resources delineation in order to improve the accuracy of the resource distribution. It is also necessary to adopt a refined evaluation system for each coded item.

우리나라 대하천 상류 하천습지의 지형경관- 영산강 상류 하천습지를 사례로 -
박의준,김성환,윤광성 국토지리학회 2005 국토지리학회지 Vol.39 No.4
This study aims to investigate the geomorphic landscape of riverine wetland in the large river upper stream, Korea peninsula. So we selected Youngsan river upper stream as a stusy area. The results are as follws. First, study area is composed of river-channel wetland and back swamp, and river-channel wetland can be divided into three distinct geomorphic units on the basis of landorm and eco-function. Second, there are many diverse micro-landforms in the river-channel wetland, and these lanforms fulfill the diverse ecological function of riverine wetland. Third, back swamp has a role in supporting eco-corridor for river fauna, and protecting a river from terrestrial pollution source. Fourth, low relief piedmont behind back swamp has a role in providing a eco-corridor for mammals and insects, so this area should regarded as a important part for ecological wetland management. 이 연구는 우리나라 대하천 상류에 발달한 하천습지의 지형경관 및 생태적 기능을 분석하는 것을 주목적으로 하였으며, 사례지역으로 영산강 상류 하천유역을 선정하여 살펴보았다. 이 연구의 결과는 다음과 같다. 첫째, 연구지역은 크게 하도습지와 배후습지로 구성되어 있으며, 하도습지는 다시 상류에서 하류로 내려오면서 지형 및 생태적 특성에 의거 3개 권역으로 분류된다. 둘째, 하도습지의 각 권역에는 다양한 소규모 지형경관이 나타나며, 이러한 지형경관들은 하천습지 고유의 다양한 생태적 기능을 수행한다. 셋째, 배후습지는 습지 내에 서식하는 수서생물의 영양염류 확보를 위한 생태통로 역할 및 육지부의 오염원으로부터 습지를 보호하는 완충지 역할을 수행한다. 넷째, 배후습지와 주변 산지 사이의 완사면 구릉지는 연구지역 주변 산지에 서식하는 포유류 및 곤충 등이 습지를 이용할 수 있는 생태적 통로 역할을 한다. 이를 통해 습지주변 완사면 구릉지는 생태적 관리방안 수립에 있어서 매우 중요한 지형경관으로 평가되었다.

드론 영상을 활용한 금강 하도내 퇴적환경 변화 연구: 세종보 개방을 중심으로
윤혜연,정근비,윤광성,장동호 한국지형학회 2023 한국지형학회지 Vol.30 No.1
In this study, the changes and characteristics of sedimentary environment in Geum River channel by opening gate of Sejong Weir were analyzed using aerial photos and drone images. Sedimentary landform was classified during the study period and it has been found that the changes of area in some classes such as mid-channel island of divided type, mid-channel island of undivided type, sand barrier, and sand island were larger than that of other classes. In addition, the characteristics of area changes of the sedimentary landform were analyzed in this study. As a result, it was determined that erosion and deposition of sediments in the river was depended on the increase of flow rate and velocity by the increase of precipitation particularly during the summer rainy reasons as well as typhoons, growth of vegetation, and efficiency of dam. The results can be used as data to identify the process of conserving endangered wildlife and restoring the naturalness of the river environment.

무인항공기를 활용한 금강 하도내의 퇴적지형 변화 특성 연구: 공주보 개방 전·후를 중심으로
윤혜연 ( Yoon Hye-yeon ),윤광성 ( Yun Kwang-sung ),장동호 ( Jang Dong-ho ) 한국지형학회 2021 한국지형학회지 Vol.28 No.4
In this study is aerial photos and UAV(Unmanned Aerial Vehicle) images were used to analyzed the characteristics of depositional landform changes in the Geum river channels before and after the opening gate of Gongju weir. Based on the depositional landform classification result, the main stream and the bare land occupied most of the area in all periods, and also found that the main stream, mid-channel island, and sand bar occupied a greater degree of area increase or decrease compared to other landforms in the classification items. As a result of analyzing the characteristics of depositional landform changes before and after the opening gate of Gongju weir, it is judged that the depositional landforms have changed due to the decreased water level of the Geum river after the opening of the weir, the summer rainy season and typhoons, river stabilization after the effluence of Daecheong dam, supply and deposition of river sediments and fixation of vegetation. The results derived from this study can be used as basic data for the study of river depositional landforms and the establishment of management and conservation plans for the landforms in river channels.
