  • Forestry and agricultural land uses constitute 85% of Korea and these land uses are typically mixed in many watersheds. Biological Oxygen Demand (BOD) concentration is a primary factor for managing water qualities of the water resources in Korea. BOD loadings from diffuse sources, however, not well monitored yet. This study aims to assess BOD loadings from diffuse sources and their affecting factors to conserve quality of water resources. Event Mean Concentration (EMC) of BOD was calculated based on the monitoring data of forty rainfall events at four agricultural-forestry watersheds. Exceedence cumulative probability of BOD EMCs were plotted to show agricultural activities in a watershed impacts on the magnitude of EMCs. Prediction equation for each rainfall event was proposed to estimate BOD EMCs: $EMC_{BOD}(mg/L)=EXP(0.413+0.0000001157{\times}$(discharged runoff volume in $m^3$)+0.018${\times}$(ratio of agricultural land use to total watershed area).

  • 우리나라는 급속한 경제발전과 도시화 과정을 거치며 도시 내부에서 안전, 환경, 교통 등 다양한 분야에서 많은 문제들에 직면하고 있다. 각 지방자치단체는 이런 도시문제를 해결하기 위해 전자민원을 접수 받아 처리하고 있지만, 민원은 해를 거듭할수록 증가하고 있는 실정이다. 따라서 본 연구는 지방 중소도시인 진주시를 대상으로 2010년부터 2015년까지 총 6년간의 전자민원 데이터를 수집하여 민원사유별로 분류하고 민원 발생지점의 위치데이터를 추출한 후 지오코딩을 통해 공간상에 점 데이터로 나타내어 공간분포 패턴분석을 실시하여 토지이용과의 연관성을 분석하였다. 그 결과, 진주시의 전자민원은 시내중심지역 내에서도 택지개발이 이루어진 주거지역, 중심상업지역, 공업·주거 혼재지역에 군집되어 발생하였다. 민원사유를 토지이용별로 분석한 결과 불법주차단속 민원이 가장 많았다. 또한 민원 발생지점의 반경 50m 내에 위치한 시설물 분포에 대해 분석한 결과 중심상업지역과 공업·주거시설이 혼재된 지역에서는 단독주택이 밀집된 지역에서 많이 발생하였다. 주거지역(구도심)의 경우 일반음식점이 많은 곳에 집중되고 있음이 확인 되었다. 이와 같은 분석결과는 민원에 대해 도시공간적 차원에서 분석함으로써 민원의 근본 원인을 찾아내어 해결방안을 모색하는데 효과적으로 활용될 것으로 판단된다.

  • 일반적으로 고밀도 도시는 더 많은 접근성도 높고, 다양한 교통시스템을 운영한다. 그러나 반대로 차량 속도도 늦고 통행 비용이 많이 들기 때문에 가구 당 년간 평균 차량주행거리는 상대적으로 적다. 결국 도시압축도가 높은 도시일수록 교통수요가 작아지는 현상이 나타난다. 오늘날 각국의 토지이용계획에서는 압축도시를 지지한다. 상당한 논쟁에도 불구하고 압축도시는 지속가능한 도시화의 중요한 대안으로 간주된다. 본 연구의 목적은 도시압축도가 높을수록 교통수요를 줄일 수 있는지에 대하여 실증적으로 규명하는 것이다. 이를 위해 본 연구에서는 서울시의 각 동(dong)간의 도시압축도와 통행발생에 미치는 영향을 분석하고자 한다. 특히, 대도시 통행발생의 근원이 되는 출근통행을 대상으로 한다. 혼합용도, 이용 패턴을 고려한 서울시 424개의 동을 육각 다이어그램으로 나타내었다. 가구 수와 제조업, 상업/서비스업 종사자 수 간의 상대적인 편차를 근거로 존의 통행발생율에 대한 도시압축도의 효과를 분석하기 위해 다중선형회귀 모형을 개발하였다. 결과적으로 주거밀도와 혼합용도지역의 통행발생율이 비교적 낮은 것으로 나타났다. 더욱이 압축지역의 사람들은 타 지역에 비해 대중교통 이율이 높은 경향을 보였다.

  • Existing natural resources were analyzed in regional scale in order to suggest natural park guidelines as a previous step of conservation plan. Results of both existing natural resources and land potentiality in preceding paper were combined to suggest comprehensive and qualitative method for understanding of natural land. Regional characteristics of natural park were, then, analyzed by this method, and specific planning guidelines were discussed. The existing natural resources were analyzed by the degree of location quotient, which were found by comparison of the grade of vegetation naturalness and the bio-physical land unit in preceding paper. Then, allowance of existing natural resources was identified, and importance of protection was described based on this result. The bio-physical land unit on Tokyo Province was found to be composed by smaller land units, which had a variety of relationship with grade of vegetation naturalness: from the specific(1st) to many stages(5th). This meant a characteric of each land unit. By this combined approach, the characteristics and spatial distribution of natural land were discussed in the regional scale, and characteristic of nateral park were analyzed in terms of natural location. National park were located in the land unit where both land capability and importance of portection were the 6th. Quasi national park and 1 province natural park were located in the land unit where land capability was the 6th and importance of protection were the 5th. Seven province natural parks were located in the land unites were both criteria under the 5th were mixed. based on the results of this study, the followings were suggested for specific planning guidelines in the case of Takao quasi nation park: (a) conservative land use within the limit of carrying capacity of this area by the conservation of biotic and abiotic natural resources, (b) conservation of both natural and semi-natural vegetation, (c) utilization of this area as a urban forest.

  • The Ministry of Environment has been working to reduce the impact on biodiversity, ecosystems, and social costs caused by soil runoff from highland Agricultural fields by setting up non-point pollution source management districts. To reduce soil loss, runoff path reduction technology has been applied, but it has been less cost effective. In addition, non-point pollution sources cause environmental conflicts in downstream areas, and recently highland Agricultural fields are becoming vulnerable to climate change. The Ministry of Environment is promoting the optimal management plan in earnest to convert arable land into forests and grasslands, but since non-point pollution is not a simple environmental problem, it is necessary to approach it from the aspect of NbS(Nature-Based Solution). In this study, a scenario for applying the nature-based solution was established for three subwatersheds west of Haean-myeon, Yanggu-gun, Gangwon-do. The soil loss distribution was spatialized through GeoWEPP and the amount of soil loss was compared for the non-point pollution reduction effect of mixed forests and grasslands. When cultivated land with a slope of 20% or more and ginseng fields were restored to perennial grasslands and mixed forests, non-point pollution reduction effects of about 32% and 29.000 tons compared to the current land use were shown. Also, it was confirmed that mixed forest rather than perennial grassland is an effective nature-based solution to reduce non-point pollution.

  • Instead of fertilizing the lands they moved to find other fertile lands and lived a feudal life agriculture and various machincs played a main role in the land reclamation. The best method of land clearing, the time and capacity in the operation and the effect of growing crops should systematically analized prior to the time of 3rd Five-year Economic Development(1972-1976) in order to cultivate 210,000ha of wasteland or the modernization of our country. The present study was investigated to find out a new working-system of mechanical land clearing and development of fertile soil. The results are as follows: 1) The first stage of productive power increases when weeds were mixed soil in the land clearing work in order to supply organic materials and to make soil swollen instead of burning or just removing. 2) The equipments such as bulldozers, harrows, power tillers and so on should be prepared in order to do a systematic work in the land clearing. 3) The work of pulling-up roots is dependent upon the forms of roots spreading under the ground. The work of the pulling-up of the straight roots was most difficult. But before the roots are pulling-up we do not know the forms of roots. 4) The cutting of soil from upside to under side land clearing method (II) Spent 6 hr 7 min 43 sec per 1 Danbo in doing land clearing and control method spent 4 hr 52 min 30 sec per 1 Danbo in doing land cearing. No significant difference could be found between II treatment type and I treatment type. 5) The volume of soil carried by bulldozer $270.38m^3$ per 1 Danbo in I type and in II type, $368.58m^3$ per 1 Danbo or about 36% increased in II type then in I type. But that is not a significant difference when considering the whole productive power of soil. 6) The land clearing of terrace by bulldozers cannot escape making the embankment slope of about $45^{\circ}$, and 25.3% should be decreased in the area. It is recommended to make use of the embankment slope by planting grass for cows. 7) The time of retary tilling increased 2.3 times or 1 hr 42 min 22 sec per 1 Danbo compared to the timesrequired in the harrowing. Because it mixed the Organic matter on ground and the harrowing of subsoil. 8) The havest of pasture growing on the land reclamation in natural slope is as follows. (a) The none fertilizers with reclaimed block of productivity decresed 1/10 than that of the farmland. Therefore the none fer tilizing in the cultivated pasture is unprofitable. (b) The havest of the manured IV treatment block was the best not only in the kinds of fertilizers but also in the kinds of pasture grass.

  • This paper discusses several topics associated with the densification caused by supertall buildings and their impact on city systems. The paper covers five key areas where a supertall tower creates a concentration of needs and effects. First, the paper comments on population shifts towards the city and how they affect carbon footprint, utilities infrastructure and transport. The effect of single- and mixed-use towers is discussed in the context of population density. The second section brings the issues of transit, accessibility and master planning into focus. The use and criticality of public transport, cycling and walking is described. Servicing and deliveries using freight consolidation and shared systems is also discussed along with their contribution to the culture of sustainable travel. In the third section the paper reflects on supertall buildings' below-ground utilities and drainage provision, particularly the challenges faced in established city infrastructures. The utilities issues associated with supertall concentration (in land-use terms) compared to equivalent low-rise distribution is also commented on in the context of surface water runoff. In the fourth section, the topic of supertall sustainability is discussed and how city systems need to respond to create desirable and affordable space for occupiers. The changing need for vertical communities, 'stacked neighbourhoods' and the notion of a micro-city is described. Finally, the paper considers the energy consumption and resilience of supertall buildings in the context of basic geometry, façade design, climate and mixed-use benefits as they impact city systems.
