The purpose of this research was to establish a green-networks from the perfective of landscape ecology in order to improve the function of urban green spaces. The study site was Dalsu-Gu in Daegu City. This research consisted of three phases. In the first phase, field surveys were carried out in order to understand existing distribution pattern of green spaces in the study site. 533 green spaces surveyed in the first phase were classified into 7 patterns and 24 types. The total area of the green spaces in Dalsu-gu was 3,329ha. Specifically the area of the 'urban nature parks' type was 57.49% of the total area of green spaces in Dalsu-gu, and it was expected that 'urban nature parks' type can play important roles in the green-networks in Dalsu-gu. Two analysis with green spaces in 9 types including 'urban nature parks', 'rivers' and 'neighborhood parks' were performed to establish a basic network frame of the green-networks. In the second phase, 'mutual connectivity analysis' and 'mutual matrix analysis' were performed to select core green spaces of a green-networks using 'areas of each green space and a distance between each space' and 'a rate of green spaces and a rate of water permeable pavement'. The results of the second phase indicated that, in mutual connectivity analysis, large green spaces apart from each other were evaluated as having higher mutual connectivity than small green spaces near to each other. In mutual matrix analysis, the green spaces with higher mutual connectivity and the small green spaces near to each other were evaluated as having better mutual matrix. In the last phase, we structured a basic frame of the green-networks in Dalsu-Gu. The results suggested that the basic frame of the green-networks in Dalsu-Gu was composed on four green-network axes and its shape mirrored a cruciform(+) of northwest${\longleftrightarrow}$southeast directions and southwest${\longleftrightarrow}$northeast directions, The Duryu neighborhood park is at the central point of this green-networks.

생태적 연결성을 확보하고 야생동물의 보전을 위해 생태적 연결통로에 대한 많은 연구가 진행되고 있지만, 현재 야생동물의 서식이 양호한 지점에 대한 보전 대책은 미비한 실정이다. 이번 연구는 생태적 연결성을 확보하는 측면에서 실제 다양한 야생동물이 서식하며 이들의 서식환경이 비교적 잘 보전되어 있는 지역을 선별하는 데 목적이 있으며, 일정 종수 이상의 야생동물이 다양하게 서식하고 서식지 주변의 토지이용특성을 분석하여 공통적 유형을 고르게 갖추고 있는 지점을 '우선보전연결구간'으로 지정하였다. 이를 위해 충청남도 당진군, 서산시, 예산군, 공주시, 부여군 등 5개 시 군을 대상으로 포유류의 다양한 서식이 예상되는 지점 500개를 우선 선정하고, 이 지점에 대해 2계절, 총 2회에 걸쳐 포유류 서식 현황을 조사하였다. 조사결과 492개 지점에서 총 12종의 포유류가 서식하고 있었으며, 각 지역별 평균 종수 이상의 종이 출현한 지점은 총 264개였다. 그리고 평균 종수 이상의 종이 출현한 저점에 대한 토지이용현황 분석을 한 결과, 산림, 논, 밭, 하천, 초지, 농촌형 건축물 등을 포함한 5~7개 유형을 가진 지점에서 높은 종 다양성을 보였다. 이를 토대로 평균 이상의 야생동물이 서식하고 공통적 유형을 지닌 지점을 "우선연결보전구간"으로 정의하였으며, 총 89개 지점을 선정하였다. The purpose of this study was to find ecologically stable areas involving the locations in which wildlife exist, and to earmark those places as "ecologically connected areas requiring preferential preservation," and through that, to reduce the perils that may occur due to urban development or road construction. The processes and the results of this study were as follows: 1. Selecting the spots in which wildlife may exist: The total study areas were analyzed by eight ecological indexes and then a total of 500 locations in study areas were selected. 2. Sorting the locations in which mammals exist: We surveyed each one of the 500 locations twice, and then confirmed that we found mammals at 492 of the 500 locations and analyzed 264 locations that the number of existing mammals was above average. 3. Analyzing the 264 locations with two indexes, the number and the frequency of the land use types: 5~7 types of land use were suitable. The types were forest, rice field, farm, river, and meadow, excluding building and road. 4. Selecting the locations that meet the above conditions: We sorted 89 locations and earmarked these points as "ecologically connected areas requiring preferential preservation" in order to expect continued existence of wildlife.

The purpose of this paper was to classify areas demanding to be transformed to green spaces and evaluate their grades for urban park and green networks. The results of this study are summarized below; 1. The results of the classified green spaces in the research areas fall into three types including children parks, neighborhood parks, and public green spaces. The three types of green spaces were analysed with recreational indexes. The zones disturbing the green-networks were sorted out. These zones should be changed into a supplementary green spaces for improving the recreational functions in the city. 2. For urban park and green networks, distances between the parks and size of the parks were adopted as indices. Based on the index of distances between the parks, disturbing zones were evaluated with 3 grades. The first grade includes primary industrial complexes and housing complexes. The second grade was observed mostly in industrial complex areas. The third grade includes housing complexes. Based on the indexes of size of parks, disturbing zones were evaluated with 2 grades. In the case of grade I, it appeared in housing complex. In the case of grade II, it appeared in industrial complex. 3. Then, we prioritized the disturbing zones with severity in order to make supplementary green spaces. Through the process, the zones of the grade I for two each recreational index were evaluated to two grades. The analysis results of evaluated zones were that grade II appeared over industrial and housing complexes widely. Grade I appeared over housing complexes. 4. It is necessary that the grade of disturbing zones should be considered as an order to make green spaces to supplement a green-network. For this, we formed a basic frame of a green-networks in Dalsu-Gu and placed the disturbing zones on the basic frame of a green-network. Consequently, The results were that the green-networks in Dalsu-Gu was composed on four green-network axes and its shape mirrored a cruciform (+) of northwest$\leftrightarrow$southeast direction and southwest$\leftrightarrow$northeast direction.

본 연구는 지구단위 차원에서 자연체험 및 휴양 가치를 평가하기 위해 객관적인 평가지표를 도출하고, 이를 토대로 체계적인 평가모형을 설정하는데 가장 큰 목적을 두었다. 우선 문헌분석 결과, 자연체험 및 휴양가치 평가를 위한 평가지표 들로는 층위구조, 포장율, 헤메로비(hemeroby) 등 총 10개의 항목이 도출되었다. 또한, 전문가 설문분석 결과, 평가지표 항목 모두가 4.4 이상으로 높은 중요도 평균값을 나타내었다. 특히 헤메로비 및 독특한 경관요소 항목은 5.8 이상으로 매우 높게 나타났다. 더불어 평가지표들을 특성별로 유형화하기 위해 요인분석을 수행한 결과, '경관구조 및 자연체험 질', '일반적 이용성', '미 시각 질' 등 총 3개의 요인으로 구분되었다. 이상과 같은 설문분석 결과를 토대로 각 요인별 가중치를 산정한 결과, '미 시각 질' 요인이 3.510으로 가장 높은 값을 보였으며, 이에 반해 '경관구조 및 자연체험 질' 요인은 3.035으로 가장 낮은 값을 나타내었다. 이들 결과를 종합적으로 분석하여 체계적인 가치평가 모형을 설정하였다. 또한, 도출된 평가모형의 타당성을 검증해 보기 위해 실 사례지를 선정하여 적용하였다. 우선 사례지의 비오톱 유형분류 결과, 비오톱 유형군은 유수지 비오톱 등 총 13개로 분류되었으며, 이에 귀속되는 비오톱 유형은 총 61개로 구분되었다. 마지막으로 기 설정된 평가모형을 적용한 비오톱 가치평가 결과, I 등급으로는 식생이 풍부한 자연형 하천, 산림과 접해 있는 소규모 수림 등 총 16개 유형으로 나타났다. 반면 II 등급은 9개 유형, III 등급은 8개 유형, IV 등급은 8개 유형, 가치가 매우 낮은 V 등급은 19개 유형으로 분석되었다. The main focus of this research is the establishment of a systemic evaluation model based on objective evaluation indices, which are drawn to assess the experiencing of nature and recreational value at the level of the district unit. First of all, as a result of a literature review, a total of 10 indices can be drawn including vegetation structure, pavement rate, and hemeroby to evaluate an assessment of natural experiences and recreational value. Also, as a result of expert survey analysis, all evaluation index items were above 4.4, which is a high importance average. Hemeroby and unique landscape factor items in particular were above 5.8, which is very high. In addition, as a result of implementing a factor analysis to classify evaluation indices according to characteristics, three factors arise: 'landscape structure and quality of natural experience', 'typical availability', and 'quality of aesthetic and visual sense.' Based on the above survey analysis results, the 'quality of aesthetic and visual sense' was the highest, at 3.510. The classification 'landscape structure and quality of natural experience' was the lowest, at 3.035. A systemic value evaluation model was established by comprehensively analyzing these results. To verify the validity of the evaluation model drawn, real sites are selected and applied. First of all, as a result of a biotope types classification of sites, biotope type groups are classified into a total of 13 including the stream biotope while its subordinate biotope types are classified into a total of 61 groups. Lastly, as a result of biotope value evaluation, which was a previously established evaluation model, there are a total of 16 types including vegetation-abundant natural rivers and small-scale woodlands near forests in grade I. There are 9 types in grade II, 8 in grade III, 8 in grade IV, 19 in the least-valuable grade V.

The purpose of this study is to analyze the business model, economic effect of Photovoltaic in rural area through input-output analysis and to derive policy implications. First, Photovoltaic business models can be classified into land rental model, farmer participation model, leased farmer model, and resident profit sharing model. As a way to operate a business, it is possible to distribute dividends through a cooperative. Second, the production inducement effect was 15,228.2 billion KRW and the industrial sectors most affected by the supply of photovoltaic (PV) were wholesale, retail and product brokerage services, industrial gases, and other chemical products, as well as market research and management support services, real estate-related services, and central banks and depository institutions. Third, the amount of added-value induced was 4,459.7 billion KRW, and the share of the top 20 industrial sectors was analyzed to be 64.1%. The industries with the largest value-added inducement were wholesale, retail and commodity brokerage services, industrial gases, other chemical products, central banks and depository institutions, and real estate-related services. Fourth, the amount of import inducement was 1,621.6 billion KRW, and the share of the top 20 industries was 66.2%. By industry sector, crude oil, individual devices, basic inorganic chemicals, and natural gas were analyzed to be high. Fifth, in the agricultural production sector according to the supply of PV, rice, vegetables, fruits, pig farming, and cattle were found to have a large impact in terms of production and added-value inducement . Based on the above analysis results, the following policy implications are suggested. First, it can be seen that the PV supply business has a significant ripple effect not only on the intermediate goods industry but also on the tertiary service industries such as consulting, real estate, and finance. Second, it can be seen that the supply of PV has a significant ripple effect on production and added value in the agricultural sector.
