Pollution load allocation can likely be much controversial, which is essential to formulate the total water pollution load management plan. Existing rules(or guidances) in Korea, can provide no specific criteria for load allocation. Therefore, this paper studied(comprehensively) possible standards how or why to choose any particular allocation method, which was applied in the Gwangju City's load allocation for the satisfaction of set water quality goal. This load allocation is basically focused on the load reduction of domestic wastewater rather than industrial wastewater, because the land-use is strictly regulated and larger sources of pollution are few in the Gwangju City. This paper recommends the city to increase the capacity of sewage treatment plants, promote sewerage maintenance, and set higher effluent standards.

지형공간정보체계와 지도학적 모델링 기법이 전형적인 토지이용계획과정을 개선시키는 방안으로 활용되었다. 미국 국립산림지역에서는 ORV전용도로, 산림 생산지, 산림 우송도로 및 야생동물 서식처 동의 토지이용이 복합적으로 결정되어야 한다. 이러한 복합적 토지이용에서 나타나는 상충성을 해결하기 위해 자동적인 지도공간 모델이 개발되었다. 서술적 모델링과 기술적 모델링기법은 복합적 토지이용의 결정을 효율적이고 효과적으로 처리할 수 있었다.

There are two ways of reducing air pollution. One is the approach of the pollutant source control and the other one is the traffic demand decreasing approach. This study is focusing on the approach of land use planning and optimal location of urban facilities because those are the basic cause to generate transportation demands. So, the purpose of this study would be to analyze the changes of NOx and CO distribution on environmental air by functional hierarchy of urban roads and to make evaluation model of 'Transportation-Land Use -Air Pollution'. It will contribute to improve the air pollution level at same actual traffic generation according to different location.

This paper investigated policies that drive the sustainable management of Ivorian forest which disappear at an annual rate of 250000 hectares. Based on an inter-temporal model for optimum allocation of forest land to three competing uses, the article found that sustainability depends on the incentive structure, of which forest taxes and fees are a key, though obviously not the sole, component. The study proposed to increase the area fee level by accounting for environmental externalities generated by forest harvesters and farmers. The paper showed that the area fee is a decreasing function of the forest natural rate of regeneration and the reconversion rate of agricultural surfaces. Finally, at the given forest natural rate of regeneration and the reconversion rate of agricultural surfaces, the model argued that the area fee need to be progressive (arithmetic progression) in the context of ecological equilibrium break while it should remain constant in normal situation.

The objectives of this research were to predict land-use/land-cover change at the Sakaerat Environmental Research Station (SERS) and to analyze its consequences on the distribution for Black-crested Bulbul (Pycnonotus melanicterus), which is a popular species for bird-watching activity. The Dyna-CLUE model was used to determine land-use allocation between 2008 and 2020 under two scenarios. Trend scenario was a continuation of recent land-use change (2002-2008), while the integrated land-use management scenario aimed to protect 45% of study area under intact forest, rehabilitated forest and reforestation for renewable energy. The maximum entropy model (Maxent), Geographic Information System (GIS) and FRAGSTATS package were used to predict bird occurrence and assess landscape fragmentation indices, respectively. The results revealed that parts of secondary growth, agriculture areas and dry dipterocarp forest close to road networks would be converted to other land use classes, especially eucalyptus plantation. Distance to dry evergreen forest, distance to secondary growth and distance to road were important factors for Black-crested Bulbul distribution because this species prefers to inhabit ecotones between dense forest and open woodland. The predicted for occurrence of Black-crested Bulbul in 2008 covers an area of 3,802 ha and relatively reduces to 3,342 ha in 2020 for trend scenario and to 3,627 ha for integrated-land use management scenario. However, intact habitats would be severely fragmented, which can be noticed by total habitat area, largest patch index and total core area indices, especially under the trend scenario. These consequences are likely to diminish the recreation and education values of the SERS to the public.

토지이용 분류 체계상에서의 종류라는 개념은 토지이용 변화의 분류 체계성에 그대로 적용시킬 수가 있다. 본 연구에서는 선형 판별 함수를 원용하는 최우법(Maximum likelihood method)으로 산출되는 토지이용분류의 공간적 결과와 Markov 전이 행렬 방법으로 산출되는 정량적 결과가 상호 보완하는 의미에서 합성모형으로 통합되었다. 본 연구에서는 다변수 판별 함수의 계산법과 Markov 연쇄행렬 계산법에 관하여 토의되고 그 합성 모형을 대상 지역에 실제 적용하여 그 결과 '90년, '95년 토지이용도가 예측 작성되었다. 모형화의 문제 및 예측의 정확도 역시 더욱 토의 되어야 하며 추후 개선의 여지를 남긴다.

본 연구는 도시계획의 중요한 의사결정 중의 하나로서 토지이용계획을 위한 적지분석에 지리정보시스템의 접목을 시도한 것이다. 도 농 통합 이전의 구미시 지역을 대상지역으로 하여 관련 환경인자들과 가중치 등의 분석기준을 결정하고, GIS 데이터베이스를 구축하였다. 또한 위성영상처리를 통하여 추출한 토지이용/피복도와 NDVI 식생도를 데이터베이스에 포함시켰다. 중첩법을 이용하여 주거, 상업, 공업, 녹지지역의 토지용도별 적지를 등급별로 도출하였다. 연구지역의 4가지 기능공간에 대한 적지분석 결과는 기존 토지이용 및 도시기본계획상 토지이용구상도와 비교되었다. 더 나은 분석을 위해서는 실제적인 개발계획, 지가자료, 토양자료 등이 포함되어야 하며, 토지 이용별 수요추정 자료를 추가한다면 토지이용별 입지 배분 및 분포면적의 신뢰도를 더 높일 수 있을 것이다.

This study is to predict the spatial expansion of urban areas by applying CA(Cellular Automata)-Markov technique considering MCE(multi-criteria evaluation) and MOLA(multi-objective land allocation) of factor analysis. For the 10 administration districts$(3677.3km^2)$ including the whole Anseong-cheon watershed, the past six temporal land use data(1973, 1981, 1985, 1990, 1994, 2000) from Landsat satellite images were prepared. During this period, the urban area increased $233.71km^2$. Using the 36 indices composed of topological characteristics, population and land use change, the final factor map of MOLA was produced through 5 maps of MCE. Using 1990 and 1994 land use data, the 2000 predicted urban area of CA-Markov with factor map showed 0.06% improvement of absolute error comparing with that of CA-Markov without factor map. By the CA-Markov technique considering factor map, the 2030 and 2060 urban area increased $58.94km^2(0.78%)\;and\;60.14km^2(0.81%)$ respectively comparing with 2000 urban area$(313.19km^2)$. The 2030 and 2060 paddy area decreased $93.28km^2(2.54%)\;and\;93.65km^2(2.55%)$ respectively comparing with 2000 paddy area$(1383.23km^2)$.

The allocation of margin of safety (MOS) at a uniform rate to all areas of the unit watershed makes it very difficult to keep the load allotment stable in the area for lack of reduction measures like forest land. This study developed an equation to calculate margin of safety differentially according to the regional characteristics. The equation was formulated on the basis of the regional characteristic factors such as a load contribution factor for land use type and a site conversion factor for the unit watershed. The load contribution factor represents a contribution of loads from a particular land use. The site conversion factor was derived from the site conversion ratio of a unit watershed. Margin of safety for the non-point pollution load in the land use sector decreased by 20~25% in three river basins. The margin of safety in the unit watersheds with low site occupation ratios decreased in high rate, while in the unit watersheds with large urban area decreased in low rate. With the application of the differential margin of safety considering regional characteristics, not only the reduction of pollution loads can become lighter but also it can be easier to develop plans for Total Maximum Daily Loads (TMDLs) even where the reduction measures are not available.

본 연구의 목적은 GIS를 이용하여 토지이용상태에 따른 대기오염현황을 분석하고 대기오염측정소 이력 및 분포의 적정성을 분석하는데 있다. 대상지역 TMS자료의 계절별 오염농도로부터 대기오염분포도를 작성하였으며 토지피복지도를 기본으로 하여 토지이용상태를 대기오염특성이 잘 나타나는 주거, 상업, 공업, 교통, 비오염 지역으로 분류하였다. GIS의 중첩분석을 통하여 토지이용상태에 따른 대기오염현황을 분석함으로써 주 오염원을 파악할 수 있었으며 이는 일반적인 대기오염의 특성과 일치하는 결과를 얻을 수 있었다. 측정소 이력 및 분포의 적정성 분석에서는 측정소가 서로 인접하거나 주변 토지이용상태가 유사할 경우 대기오염측정값이 유사하게 나타나며 향후 측정소의 위치선정시 이러한 특성을 고려할 필요가 있음을 알 수 있었다.
