Ecosystem management means using an ecological approach to achieve the multiple-use management of national forests and glasslands by blending the needs of people and environmental values in such a way that national forests grasslands represent diverse, health, productive, and sustainable ecosystems (Robertson 1992). Ecosystem management is a concept whose time has come. But ecosystem management is only a concept for dealing with larger spatial scales, longer time frames, and many more variables(ecological, economic, and social)than have commonly been considered in past management approaches. 21st-century forestry will be defined by understanding and managing complexity, providing a wide range of ecological goods and services, and managing across broad landscapes. The adoption of ecosystem management as a guiding philosophy for 21st-century forestry represents a move from simplified to complex conceptions of ecological organizational systems. Like sustained yield forest management, which was a radical departure from current practice when it was introduced near the turn of the century, the protection and sustainable management of forest ecosystems seems destined to become the " Conventional wisdom" in forest resource management in twenty-first century(Sample 1991). The sustained-yield paradigm that dominated this century was based on several key assumptions : To develop sustainable forest ecosystem management, we must change from managing forest states to managing process from focusing on trees to focusing on ecosystems. As opposed to compartment and stand-level management, foreset ecosystem management must be placed in a larger context we refer to as dynamic landscape heterogeneity. Sustainable ecosystem management should be seem not merely as protecting additional old-growth reserves and providing landscape corridors, but also as a necessary change in managing the larger commodity forest matrix of the landscape. The maintenance of species diversity, functional diversity, and processes through harvesting cycles is needed not only for wildlife, but also to sustain the long-term productive potential of forests and to provide a buffer against future uncertainty, such as climatic change. A formal process of adaptive management will required to maximize the benefits and to achieve the long-term objective of ecosystem management. Adaptive management is a crucial element of any ecosystem-based strategy. It is based on a continuing process of action based on planning, monitoring, evaluation and adjustment.

This study that promote the forest road which deserve of the special of our country is devided into three parts such as the arrangement of forest road, the mechanical character of forest road and the utilizition of forest road. The result of these studies as follows: The line arrangement of forest road can be made by the shape of mountain and the resource of it.That is, the first, we have to choose forest road to acquire the shortest distance and the biggest efficiency. The second, if the condition of field is not suitable for the object, we have to install annexed facilitate like the working road and the mechanical road. In order to do these easily, we have to pay attention to surveying and project.

21世紀 森林經營 新思考에 관한 硏究

尹光培 건국대학교 1992 學術誌 Vol.36 No.2

This study was carried out for the purpose of showing the future of the forest vision and realizing the instinct value as a renewable resources. On the new idea of forest management in 21st century is as fellows: 1 Multiple use is a commodity model, treating forests expediently as nothing but resource. Multiple value is a community model, respecting both human and forest communities and seeking as intergrated appreciation and development of value provided by forests. The five statutory multiple uses are recreation, timber, range, watershed, and wildlife and fish. Expanding these, ten cagegories ◁표삽입▷(원문을 참조하세요) could intergrate human and biotic values and emphasize realms that multiple use often neglects. 2. Multiresource forest management is the deliberate application or withholding of labor/capital inputs to or from a biophysical forest system for the simultaneous production of several desirable outputs. 3. New idea of holistic forestry is to compare it to the traditional philosophy of multiple use forest management that has been a foundation point for sound forest practice. Holistic forestry means essentially the same thing as our traditional, and very effective, that is concept of multiple use management. 4. New strategies in forest management is an implicit seperation of man from nature. As nature was designed a forest with interrelated processes. Restoration forestry is suggested as a solution involving the act of restoring the Forest, returning it to its original condition.

In terms of habitat conservation, it is essential to develop a habitat assessment system that can evaluate not only the suitability of the current habitat, but also the health and stability of the habitat. This study aimed to develop a methodology of habitat quality assessment for endangered species by analyzing various existing habitat assessment methods. The habitat quality assessment consisted of selecting targeted species, planning of assessment, selecting targeted sites, assessing performance, calculating grade, and expert verification. Target sites were selected separately from core and potential habitats using a species distribution model or habitat suitability index. Habitat assessment factors were classified into ecological characteristic, landscape characteristic, and species-habitat characteristic. Ecological characteristic consisted of thirteen factors related to health of tree, vegetation, and soil. Landscape characteristic consisted of five factors related to fragment and connectivity of habitat. Species-habitat characteristic consisted of factors for evaluating habitat suitability depending on target species. Since meanings are different depending on characteristics, habitat quality assessment of this study could be used by classifying results for each characteristic according to various assessment purposes, such as designation of alternative habitats, assessment of restoration project, and protected area valuation for endangered species. Forest habitat quality assessment is expected to play an important role in conservation acts of endangered species in the future through continuous supplementation of this system in regard to quantitative assessment criteria and weighting for each factor with an influence. 본 연구에서는 서식지 질적 평가에 대한 추진체계를 6단계로 구분하고, 평가 대상지 선정 방법과 서식지 질적평가 항목을 제시하였다. 서식지 질적 평가 항목은 서식지의 건강성, 안정성, 단절화 및 파편화 정도, 서식지 적합성, 위협 정도 등에 대한 종합적인 평가가 가능하도록 구성되었다. 그러나 현시점에서는 자료부족으로 인하여 서식지 질적 평가 체계가 적용 가능한 멸종위기종이 극히 일부에 해당된다. 서식지 질적 평가 체계는 향후 멸종위기종들에 관한 서식환경자료가 축적되고 이를 기반으로 평가항목들에 대한 정량적 기준 및 가중치가 부여되면 멸종위기종 별 주요 서식지에 대한 보전방안 마련에 크게 기여할 것으로 기대된다.

Intensive forest management rehuires reliable information on stand dynamics growth, and yield. A variety of modelling options will probably be required to provide information on which to base the forest management decisions. In this paper, modelling alternatives are regardes as part of continuum of complementary systems rather than as multually exclusive options. A brief review of selected stand modelling alternatives is given, with some discussion of general situation for which the various approaches might prove efficient; and data base for stand modelling are considered. Suggestions are offered for modelling Larch (Larix leptolepis Gordon) stands.

To study the proposals for the advanced structure of forestry project in Korea. We analyze the structure of ownership, capital, labor, maturity and management unit. The advanced structure of forestry project is up to improve the production and marketing structure(flow system). The recommendation about advanced structure of forestry can be summarized as follows: 1) It is insufficient for the combination of five kinds of production factor to the forestry development. 2) The cooperative forest owner's management is advantageous to the scale-up to the forest land size and the adaption of intensive forest management. 3) Expansive of government support is needed for the forest road investment, regional forest policy, marketing project, and benefit from taxation is necessary,(if the case for forest management inheritance tax exemption and so on) 4) It is desirable that forestry association rearranges the inner organization to activities the forest network system. 5) It is necessary to improve the software factor like the forest law and forest extension system. And to specialize the extension function into the Forestry Administration officials organization.

本 硏究의 目的은 結果의 生長을 基礎로 앞으로의 林分狀態와 收穫量을 예측하는데 있다. PKO-RAIENSIS의 Simulator는 基礎生長 單位로서 單木을 使用하여 잣나무 經營林分의 생장 model로 이용하였다. PIORAIENSIS는 林分의 크기, 地位指數, 隣接木의 경쟁 등을 函數에 의해서 연년히 林分에 상호 적응시켰다. 生長量을 確率的 要素에 대한 變數로 조정하였다. Simulation을 통해 얻은 結果는 다음과 같다. 1. 樹高生長을 고려한 林分의 植栽本數는 acre當 1,000本(2,471/ha)이었다. 2. acre當 1,000本을 식재할 경우, 競爭指數는 林齡 9일 때 0.0077에서 계속 增加하여 林齡 40일 때 최대치 0.6404에 이른 후 감소하여 林齡 50에서 0.4535로 나타났다. 3. acre當 1,000本을 식재했을 경우 1차 間伐은 林齡 15년에서 이루어졌고, 재적은 256feet³(7,3m³)이었다. 또 2차 間伐量은 林齡 30년에서 616feet³(17.4m³)로 나타났다. 4. 林分의 最大收穫量은 林齡 50년에서 4,322feet³(122.4m³)로 얻을 수 있었다. PKORAIENSIS, the Fortran based simlutor, developed a growth model for the Korean White pine(Pinus Koraiensis S. et Z)using individual trees as the basic growth. In PKORAIENSIS, trees are assinged coordinate locations in a stand and annual growth rate as a function of their size, the quality of the site, and the competition from neighboring trees. The growth are adjusted by the variables of stochastic elements. The subroutine are developed to simulate the effects of the site preparation, thinning. and fertilization on tree and the stand development. The results obtained through the simulation re as follows: 1. PKORAIENSIS of the trees planted per acre is 1,000trees under the consideration of the height of growth. 2. The competition index for 1,000trees at the age of 9 is 0.0077 and continuously increase until it reaches to maximum of 0.6494 at the age of 40, and then decreases to the 0.4535 of 50 3. We obtained, for 1,000 trees 256 feet³(7.3m³)when the first thinning is done at the age of 15, and 616 feet³(17.4m³)at the second thinning at the age of 30 4. The maximum yield, 4322 feet³(122.4m³)is obtained at the age of 50.
