When we research a landscape or make a Landscape Impact Assessment, we use the image of a specific season like summer or fall. Since there are four distinct seasons, each with a different landscape, researchers need to understand viewers′visual preferences for individual seasonal landscapes. The purpose of this study is to investigate viewers′visual preferences according to seasonal change and the respondent′s age, gender and profession. In this research, the independent variable is season: suing, summer, fall, winter and snowy winter. Three landscape types used in the experiment: forest, street and agriculture. Each landscape type has two sites for reliability. The assessment media for this research are pictures featuring landscapes taken in each of the four seasons. The study used the "paired comparison" method for taking the score of visual preference. The results of this study are as follows: 1. The summer landscape has the highest visual preference score. However, spring and fall landscapes should also be considered for visual landscape evaluation. 2. The visual preference of winter landscape covered with snow is very high, but since snow is temporal and irregular, it is difficult to consider this factor for visual landscape evaluation. 3. The visual preference score of winter is the lowest of four seasons. The attractive factors of spring are flowers, summer is greenery and fall is autumnal tints. But these are not present in winter. 4. The result of visual preferences according to age groups, gender and profession have no serious differences. 5. Visual preference to scenery of 4 seasons by age group was not different from general preference and thus was concluded to have no connection with age. 6. As a result from the research of visual preference to scenery of 4 seasons by sex, women were shown to like snow-scene more than men. This study presents an indication of general preferences of seasonal landscapes. It is expected that more advanced study will proceed after this one.

유역 내 산림은 생태계 유지에 있어 중요한 역할을 맡고 있으며 생태네트워크 체계를 구성하는 주요 기반 환경이다. 그러나 지난 수십여 년간 행해진 무분별한 개발사업으로 인해 산림 파편화 및 토지이용 변화가 가속화되었으며 본래의 기능을 상실하게 되었다. 산림 생태계를 파악하는 데 있어 산림의 구조적 패턴은 생태적 과정과 기능에 직접적인 영향을 미치기 때문에 변화패턴을 파악하고 분석하는 것은 중요한 인자라 할 수 있다. 이에 본 연구는 금강 상류 댐 유역을 대상으로 FRAGSTATS 모델을 통해 시계열적인 토지피복변화에 따른 산림 경관의 구조적 변화를 분석하였다. 토지피복 변화탐지를 통한 금강 상류 댐 유역 내 토지피복변화는 1980년대부터 2010년대까지 산림 33.12km²(0.62%), 시가화건조지역 67.26km² (1.26%) 증가하였고 농업지역 148.25km²(2.79%) 감소하였다. 유역 내 산림 경관분석결과 No sampling 분석에서는 경관백분율(PLAND), 면적가중근접지수(CONTIG_AM), 평균 중심지 면적(CORE_MN), 인접지수(PLADJ)가 증가하였고 패치수(NP), 경관형태지수(LSI), 응집지수(COHESION)가 감소하였다. Moving window 분석을 통해 구조적 변화패턴을 파악한 결과, 경상북도 상주시, 충청북도 보은군, 전라북도 진안군 내 산림 경관은 상대적으로 잘 보전되어 있었으나 충청북도 옥천군, 영동군 그리고 충청남도 금산군 사이의 경계부와 전라북도 무주군과 장수군 인접 지역의 산림 경관에서는 파편화가 진행되고 있었다. 결과를 토대로 추후 해당 지역의 산림 관리전략 수립 시 파편화 지역을 대상으로 조림사업을 수립할 필요가 있을 것으로 사료된다. 본 연구를 통해 산림 경관의 파편화가 예상되는 지역을 도출할 수 있었으며, 유역 산림의 건전성 평가 및 관리계획 수립을 위한 기초자료로써 활용될 가능성을 기대할 수 있다.

본 연구의 목적은 오대산 국립공원을 대상으로 수치표고모텔, 용도지구 및 토지피복분류도를 작성하여 경관특성을 파악하고, 가시권분석을 통해 시각적 경관관리방안을 제시하는 것이었다. 분석결과, 용도지구는 자연환경지구의 면적이 감소하고 자연보존지구가 상대적으로 확대되어 보전의 성격이 강화된 반면, 취락지구도 면적이 증가하여 개발 가능성이 증가하였다. 토지피복은 자연환경지구에서 농경지 및 도시지역의 증가가 나타났다. 가시권분석을 통해 가시중복도가 높게 나타난 지역은 대부분 자연보존지구였으며 산림지역이 대부분을 차지하였다. 그러나 일부지역은 자연환경지구 내에 포함되어 지속적인 경관관리가 요구되었다.

The purpose of this paper is to examine the visual evaluation structure about the formal changes of streetscape by the different moving speed in two alternative control plans for the building height and the setback regulation. The virtual reality system is applied to the experimental tool. Eighty-two experimental models are made in consideration of the height and the setback of the building regulation cased by Midou-suji street in Osaka City, Japan. and ten typical models are selected by pre-experiment. Since the changes of the landscape structure consists of the height and the setback of the building, four the evaluation items are set: grade of continuity, order, openness, preference. As there are eighty-two landscape models which are too many to be applied in this experiment, ten role models are drawn out and used in this experiment. The mean difference test, discriminant analysis, and multiple linear regression methods had been used for the statistical analysis methods. The results of this study are as follows; 1) It is found out the fact of the difference evaluation structure amount experiments models. 2) From the sketch analysis and interview, it is found out difference cognition structure by the moving speed and alternatives. 3) From the discriminant and regression analysis, it is found out that the evaluation value about continuity becomes low by the moving speed change from walking speed to driving speed. We suggest that continuous experiment should be made with a variety of groups and models, and general and universal results should also be come out of the experiments above.

1960년대 이후 빠른 도시화는 도시 자연환경, 그중에서도 도시 하천을 많이 변화 또는 훼손시켰다. 한강은 서울의 중심을 흐르는 강으로서 60년대 이후 도시화로 인해 유로변경, 천변백사장 망실 등 자연경관이 급격히 변화하였다. 오늘날 하천은 도시의 생태통로로서 뿐만 아니라 천변 녹지 및 오픈스페이스로서 그 가치의 중요성을 인정받고 있다. 따라서 변화된 하천자연경관은 환경복원의 주요 대상이며 이를 위해서는 훼손되기 전 하천경관의 원형파악이 필수적이다. 경관의 원형파악을 위해서는 촬영당시의 지형, 지물의 구체적인 정보들을 보유하고 있는 항공사진과 고해상도 위성영상 등의 원격탐사 자료를 이용, 대상지의 지형, 지질, 식생, 토괴 등을 판독하여 자연경관의 변화를 파악하는 것이 효과적이다. 최근에는 항공사진 외에도 IKONOS 위성 영상과 같은 고해상도영상을 판독한 후 이를 수치사진측량기법을 이용하여 경관변화의 계량적 파악을 시도하고 있다. 본 연구에서는 한강을 대상으로 1966년부터 2002년까지의 변화를 상기 방법을 이용하여 하천 자연경관변화를 파악하였다. 판독결과 대부분의 하천 변화는 모래사장과 곡류하천이 소멸돼 다른 용도로 전환된 것으로 나타났으며 모래사장은 하천 직강화로 인해 하천으로 변했으며 하천은 단지 및 택지개발에 따른 천변도로 개설로 인해 소멸된 것이 가장 큰 원인으로 각각 나타났다.

In this study, we analyzed the changes in the topographical landscape and the sedimentary environment to evaluate the ecological value of the Dongcheon Estuary and protect the wetland, and presented the conservation management method of the Dongcheon Estuary. Based on the result of topographical landscape analysis, agricultural land tended to decrease continuously, and artificial structures gradually increased. Moreover, in sediment analysis, the Dongcheon Estuary showed both the characteristics of river sediments and coastal sediments, and in some areas problems such as acidification and nutritional imbalance appeared. Therefore, in order to protect and manage the Dongcheon Estuary with high ecological value, it is necessary to limit the development around micro topography and minimize the artificial damage in the Dongcheon Estuary. In addition, efforts such as securing facilities for reducing pollutants and freshwater wetlands for pollutants, that flow in from nonpoint pollutants are required.
