This study was conducted to investigate physicochemical property changes from July 1998 to August 2001 in Mt. Bukhansan National Park. Four water sampling points were selected to measure the quality of stream water in the northeastern part of the Mt. Bukhansan National Park. The results were summarized as follows; In spring, the average pH of stream water was below the first class of the river water quality standard, while it was normal level in summer. The average electrical conductivity was about 2.3~3.3 times higher in downstream water than in upstream water during spring and summer. The contents of anions($Cl^-$, $NO{_3}^-$, $SO{_4}^{2-}$) were about 1.1~7.4 and 0.4~11.4 times higher in downstream than in upstream water, respectively. These results indicate that water quality was poorer in downstream than in upstream water. We suggest that stream water in the Mt. Bukhansan National Park should be protected from impacts of snow melting mineral particles in spring season and human impacts like wastewater of point source in summer season.

This study was conducted to investigate influences of solifluction and sediment runoff on the stream water qualities during the spring season. The study sites were four points in the northeastern area of the Bukhansan National Park. And, field surveys were carried out in the spring of 1999, 2000 and 2001. The results of this study were summarized as follows; During the investigation period, the amounts of sediment caused by solifluction on stream side slopes in the downstream were 1.3∼1.7 times as large as those in the upstream. The pH of sediment caused by solifluction was a potential influence on the pH of stream water. Amounts of dissolved Cl^-, NO₃^- and SO₄^(2-) in stream water were proportion to the average amounts of Cl^-, NO₃^- and SO₄^(2-) in the sediment caused by solifluction. In the spring, the average pH of stream water was lower than the first class of the river water quality standard because of increasing chemical concentration as well as the contents of anions(Cl^-, NO₃^- and SO₄^(2-)) in the spring season. Also, the average electrical conductivity of water in downstream was about 2.3-3.3 times higher than that in upstream. The amounts of anions(Cl^-, NO₃^- and SO₄^(2-)) of water in downstream were about 1.2∼7.4, 1.1∼3.9, 1.1∼1.4 times higher than those in upstream, respectively. Therefore, these results showed that the water quality of downstream was worse than that of upstream. As a result of regression analyses, the linear and exponential equation of pH and water quantity was pH = 1.7926 × stream water quantity + 5.9577(R² = 0.46), and those of electrical conductivity and water quantity was EC = 34.417e^(3.6334 × stream water quantity(m/sec) (R² = 0.44).

This study was carried out to introduce current status and development strategy for an environmental restoration of stream side in Japan, and to consider a methodology which could be effectively applied for the environmental restoration of stream side in Korea. Since the end of 20th century, the native ecology and landscape of Japan remained only a limited areas such as stream side, water side and forest areas. Therefore, recently the works of forest conservation and erosion control of environmental restoration on stream side tended to increased. The strategic prospects of environmental restoration in Japan were summarized as follows : 1. From the ecological point of view, we have to develop a certain method and technology in construction of forest conservation and erosion control to prevent environmental problem from erosion control works. 2. We have to restore not only a continuity of stream side forest from a primitive area to an estuary but also the stream side forest to preserve and restore a stream side vegetation on a primitive watershed areas. 3. We have to improve a method of construction or removal of a structure which were constructed in the stream to restore a water side environment and an interaction system for an integration on a forest land, stream, and erosion control. Additionally, we have to establish an integrated evaluation method and an enforcement system after investigation of influences on natural environment, stream, and forest etc. 4. We have to conduct an integrated research to investigate the ecosystem of stream side, and construct environmentally friendly water park and erosion control park which considered natural environment and its landscape. Additionally, we need to introduce and adopt a natural style stream construction method to restore a water side areas.

To investigate the restoration procedure on soil physical properties at the surface of visiting road affected by rest-year system. This study was carried out at visiting roads of stream of Chilsun in Jirisan. Mean soil strength in 20cm of soil depth was lower in the Rest-Year System areas (1.5-1.9 times in Site 2, 1.1-7.5 times in Site 3) than in the control (Site 1). Soil strength was recovered by the Rest-Year System in the national park. Mesopore rate (pF 2.7) in 0-15 cm of soil depth was higher in the Rest-Year System areas (1.2 times) than in the control. This indicates that mesopore rate is rapidly restoring in the Rest-Year System areas. Pore space rate in 0-7.5 cm of soil depth was higher in the Rest-Year System areas (23.2% in Site 2, 23.6% in Site 3) than in the control (22.4% in Site 1). Pore space rate in 7.5-15 cm of soil depth was also higher in the Rest-Year System areas (22.9% in Site 2 and Site 3) than in the control (18.9% in Site 1). Soil pore space was remediable by the Rest-Year System. Bulk density in 0-7.5 cm of soil depth was lower in the Rest-Year System areas (1.674g/cm3 in Site 2, 1.668g/cm3 in Site 3) than in the control (1.723g/cm3 in Site 1). Bulk density in 7.5-15 cm of soil depth was lower in the Rest-Year System areas (1.785g/cm3 in Site 2 and 1.721g/cm3 in Site 3) than in the control (1.721g/cm3 in Site 1). Soil bulk density was decreased in the Rest-Year System areas of the national park. Amount of soil erosion was lower in the Rest-Year System areas (0.017m3/km/yr in site 2, 0.023m3/km/yr in site 3) than in the control (0.054m3/km/yr in site 1).

임업 중에서 시장과 정부의 규제가 충돌하는 대표적인 산업을 토석산업이라 할 수 있다. 특히, 경제적 측면과 환경, 경관, 재해측면을 동시에 고려하기 어려워 적정한 규제 및 규제개혁의 검토를 통해 관련 법 조항의 개정이 필요한 실정이다. 본 연구는 전국 54개소의 토석채취지를 대상으로 산지관리법에 명시된 환경 및 경관피해, 재해저감 실태에 대한 이행상태를 조사함으로써 토석채취자 및 관련 종사자의 준법정신을 확인하고, 차후 종사자를 대상으로 한 교육, 법률 개정에 있어 기초자료로 제공하고자 실시하였다. 산지관리법과 하위 법령의 총 22개 항목에 대하여 이행상태를 분석한 결과, 환경피해 저감 관련 법 조항은 이행상태가 대체로 양호한 것으로 나타났으나, 경관피해 저감 관련 법 조항은 대부분의 토석채취지에서 해당사항이 없는 것으로 나타났다. 이것은 산림경관을 중요시하는 사회적 분위기에 따라 토석채취로 발생하는 경관피해를 최소화하고자 한 결과로 판단된다. 아울러 재해방지를 위한 침사지 설치 이행상태는 양호한 것으로 나타났으나, 침사지와 연계된 방류수의 배출기준(수질오염방지)의 정립 및 제시를 통해 효율성을 높일 필요가 있을 것으로 판단된다. 따라서 본 연구결과와 차후 진전된 연구를 통해 다양한 법률이 적용되는 토석산업에 대해서는 보다 명확한 내용과 근거를 기반으로 현실성 있는 규제와 산업의 발전을 위한 정책이 수립되어야 할 것이다. Quarrying industry is typical industry that troubled between the market and government regulations in the forestry. Especially, it is difficult to consider aspects of economics and environment, landscape, disaster at the same time. Therefore, Quarrying industry need revised statutes according to regulatory reform and mitigation. This study conducted to provide basic data for regulatory reform and mitigation in quarrying industry. We surveyed 22 article of mountainous districts management act and lower statutes to employers and business interests on quarry 55 places in the Republic of Korea. As a result, fulfillment status of environmental damage reduction and disaster prevention were satisfactory. But fulfillment status of landscape damage reduction were not applicable. This result is due to the social mood that emphasizes the forest landscape. But there is need to improve the efficiency of grit chamber through present standard on effluent(water pollution prevention). In conclusion, policies should be established for realistic regulation and developed industry to quarrying industry.

The objective of this study was to introduce the current status and development strategy for the environmental restoration of stream side in Japan, and to consider the methodology which could be effectively applied to the environmental restoration of stream side in Korea. 1. We should establish a new paradigm of forest conservation and erosion control which can emphasize the restoration of the stream side ecosystem and reduce soil movement in the areas. Also, in the past, the objective of forest conservation and erosion control was to fix soil by constructing permanent structures. The direction of future forest conservation and erosion control needs to be new forest conservation and erosion control technology to prevent large scale soil movement but allow small scale soil movement to conserve sound ecosystem and biotic habitats. 2. In the past, the goal of forest conservation and erosion control planning was to fix the amount of soil movement by constructing permanent facilities. Forest conservation and erosion control planning in the future needs to change the techniques which could prevent soil movement from large scale of soil disasters, but allow soil movement effectively to a small and middle scale's soil movement. Also, it is considered to change erosion control dams from non passing type to passing type. 3. In the point of ecological conservation aspects, we should evaluate the effects of new forest conservation and erosion control methods which are emphasized on the restoration of the stream side ecosystem. Also, forest conservation and erosion control construction projects for restoring stream and river ecosystem should be planned for perfectly restorating their ecosystems by the way of sustainable maintenance and management. 4. The restoration direction of stream and river ecosystems needs to be restoring the diversity of small geographies such as waterway, shoal and puddles rather than flattening stream bed. And the restoration of the stream side ecosystem should provide continuity of the stream side environment which allows desirable biological habitats, and environmentally sound facilities to harmonize with the environment.

This study was carried out to introduce current status and development strategy for an environmental restoration of stream side in Japan, and to consider a methodology which could be effectively applied for the environmental restoration of stream side in Korea. The strategy prospects of environmental restoration in Japan were summarized as follows : 1. When we establish the long term erosion control planning, we should make detail planning after considering of a certain block of watershed units. Because most of the disaster is caused by soil movement which was occurred by water contents. 2. Nowadays, the general torrent erosion control planning system in Japan focused on reducing the sediment such as by placement of erosion control facility and by restoration of afforestation, after calculation of several factors including expected amount of sediment, and the different amount of planned sediment and allowable sediment. 3. In the past, the goal of forest conservation and erosion control planing was to fix the amount of soil movement by construction of permanent facilities. While, the goal of forest conservation and erosion control planning in the future needs to change the techniques to a small and middle scale's soil movement which could prevent soil movement from large scale of soil disasters, but allow soil movement effectively. Also, it is considered to change erosion control dams from non passing type to passing type. 4. Restoration of stream-side ecology, erosion control for the conservation of ecology should be planned and conducted cautiously based on concepts of ecology conservation and development of environmentally sound techniques.
