대규모의 벌채, 경제수 조림, 생태계의 부적절한 보존등 서구의 산업화된 삼림경영은 환경론자들과 생태학자와 보존론자들의 거센 반발에 부딪치고 있다. 환경이 급격히 파괴되어 가고 있음에 따라 삼림경영 방침도 바뀌어져야 한다는 생태학자들의 목소리가 높아지고 있다. 지역적 임업, 사회적 임업, 자작농임업(自作農林業) 등 여러 가지 이름으로 불리는 임업 즉 지속적으로 생태계를 보호하려는 오래된 임업 경영 방법이 최근에 관심을 끌고 있다. 자연 자원을 조직적으로 경영하지 못하는 이러한 전통적인 형태의 삼림 경영 방법은 오래 전부터 많은 나라에서 수행되어 왔으나 지역사회의 필요와 생태계의 역할을 확실하게 이해함으로써 보다 높은 생산력을 올릴 수 있는 토지 이용 방법을 찾을 수 있게 될 것이다. 혼농임업경영의 성격은 지리적 위치, 규모, 사회적 또는 지역적 구조와 요구에 따라 매우 다양하다. 이 논문은 혼농임업 경영이 산업적 삼림 경영보다 경제적 생산력은 낮을지 모르나 생태계를 보호하고 생산을 지속적으로 유지하는데 훨씬 유리한 방법이라는 것을 밝혀냈다. 산업적 삼림 경영은 처음에는 혼농임 경영보다 높은 생산력을 얻을 수 있을지 모르나 시간이 갈수록 생태적인 파괴 때문에 지속적인 생산성이 저하하게 될 것이다. 전통적인 경제 분석법을 조사해 볼 때 삼림과 관련된 많은 사회, 환경적 비용을 계상 하지 않았음을 알 수 있다. 본 논문에서는 관리가 잘된 혼농임업은 지속적으로 생태계를 보존하는 문제와 경제적인 이득을 얻는 문제간에 균형을 잡을 수 있다는 것이 논의되었다. 즉 혼농임업에 대한 자가농임업(自家農林業)개발의 종합적 모델을 농업, 임업 및 환경 부분의 서비스를 상호 연결시킨 협력 방법을 제시하였다.

In this study, water protection reservoir is selected as the target which is located at the estuary of Taehwa river to analyze and examine the effects of hydraulic structure on river environment. This study examined the water quality variation characteristics among many effects of hydraulic structure on river environment before and after removal of the sediment protection reservoir when low flow is yielded. This study aims at the definition of factors which cause the change of ecological environment of river due to the effects of the sediment protection reservoir, and the proposal of the direction of environmental friendly river space development through the comparison of stream variation conditions(depth, velocity, and etc.) and riverbed variation characteristics with ecological depth condition of Taehwa-river's channel for each representative species of fish and examination those. Firstly, from the examination result of water quality when low flow is yielded before and after removal of the sediment protection reservoir for problems about water quality of river due to flow amount decrease in river, it is found that DO decreases about 0.78~0.86ppm at the lower stream of Myeongchon-gyo, and BOD decreases about 0.06~0.24ppm from right upper stream to the direction of estuary when the sediment protection reservoir is removed. It is known from the above that there is some improvement of water quality from the lower stream of Taehwa-gyo to the estuary in case of removal the sediment protection reservoir. Nextly, it is thought that the effects on ecosystem due to water depth and draw down in channel is not serious on the basis of the examination of water quality analysis result according to removal of sediment protection reservoir and hydraulic depths for reservation of ecosystem, these are 10~40cm for breeding season, 10~50cm for fry period, and 10~100cm for adult period of the representative species of fish in Korea.

This study aims to investigate the characteristics of the vegetation structure in the sectin stretching between the Jilmoi wetlands and the Donghae Observatory and to set the criteria for the basic data for a management plan including restoration afterwards. 12 plots($10m{\times}40m$, $20m{\times}20m$) were set up to analyse the vegetation structure. The analysis of the classification by TWINSPAN and ordination by DCA, importance percentage and property, distribution of diameter of breast height, growth increments of major woody species, species diversity and the physicochemical properties of soil were all analyzed. Vegetation classes were divided into 3 communities, which are community I (Pinus densiflora community), community II (Quercus mongolica community) and community III (Quercus mongolica-Tilia amurensis community). The P. densiflora community declined when competing with Q. mongolica and Fraxinus rhynchophylla and Q. mongolica competed with T. amurensis on an understory layer in Q. mongolica community. Q. mongolica competed with T. amurensis on both canopy and understory layers in Q. mongolica-T. amurensis community. P. densiflora declined and it was assumed to succeed to F. rhynchophylla or T. amurensis through Q. mongolica based on the importance percentage and distribution of the diameter of the breast height of small and middle sized trees. The age of P. densiflora was between 47 to 51 years old and Q. mongolica was 61years old. T. amurensis was 61 years old and the growth of Q. mongolica slowed a little. As the result of Shannon's index of species diversity, community I ranged from 0.9578 to 1.1862, community II ranged from 0.7904 to 1.2286 and community III ranged from 0.8701 to 1.0323. The contents of organic matter and cation were low compared to uncultivated mountain soil and it were analysed to be inappropriate for tree growth.

This study aimed at the introduction of desktop method for assessment of environmental flows developed by International Water Management Institute (IWMI) recently and its application to Geum river basin. This scheme simulated the influence on aquatic ecosystem caused by watershed development and in turn the decrease of water quantity keeping the river's own flow regime. It was found to be as very effective method although it had simple structure. Flow duration curves for different environmental classes at Sutong and Gongjoo sites were estimated according to the natural conditional scenario of Geum river basin and the results were relatively compared well with the previous studies. The behaviors of monthly average runoff time series of both sites showed the level of A class. The results of this study would provide the fundamental data to establish the future plans of monitoring or management for aquatic ecosystem of Geum river basin.

The purpose of this study is to analyze of biotope types and to develop assessment for forest ecosystem evaluation method. Vegetation types divided into 27 types. Considering the vegetation types, vegetation structures, DBH, potentials, and disturbance, it was decided to apply 58 biotope types and survey site's biotopes were divided into 24 biotope types. Assessment indicators were naturaliness, diversity, rarity, stability, potential, and disturbance. The areas given the first grade in ecological value included 9.2% of the site's total land. Areas with the second grade accounted for 43.0% of the total land. Areas with the third grade made up 47.8% of the site and mostly they were areas with dominance of fired area and artificial forest. To plan to build naturally-development for Site, there should be plans to conserve areas with the first grades. For the areas with the second, and third grades, plans for ecological land use based on conservation and restoration in terms of securing biodiversity are needed.
