After 1960 forest and ecosystem are rapidly destroyed by industrialization and urbanization. Accordingly, studies that produce vegetation map continue for forest and ecosystem management. Since 1986 national natural environment survey is being conducted in Korea. Also, vegetation information is managed properly through forest geospatial information service(FGIS) of the Department of Environment when NGIS project was promoted since 1995. But it provide dominant species information based on text. In particular, some vegetation information dose not provide to end-user. Therefore, we suggest construction method of vegetation information management system based on GIS to solve the problem. Also, we suggest connection method of related system for an accurate analysis, planning and decision-making support.

The functional change of university forest have led to need more complicated techniques for forest management strategies, and more information about forest and natural environment. Therefore the systematic tools, like the so-called Forest Information System to which apply the techniques of geographic information system, are eagerly required for collecting, editing, managing, analyzing the various data about forest and environment, and for supporting the decision-making process. The digital mapping, which could be a primary step to construct the Forest Information System, was carried out using the many kinds of thematic spatial data referring to the Seongju Experimental Forest of Taegu University. As a result, various digital maps including forest type, soil type and so on were constructed. And then we made an user-interface system to link the attributive data in management plan to the thematic spatial data. This system was regarded as the effective tool capable of the more rapid query, analysis and update of related data for systematic management of university forest. Moreover, it would be a useful tool of decision-making in devising, assessing and operating the plan of forest management and development. But there would be much room for supplementation and improvement to make the more convenient and powerful system for the external demands, therefore more concerns and efforts in collecting, revising and updating the data is continuously required.

산지를 이용하기 위해서는 규제지역 정보, 임상, 지형 등 다양한 정보가 필요하다. 반면에 산주들은 산지 정보를 획득하기가 어렵다. 산지를 개발하고자 토지 매입 등을 거친후 인 허가 과정에서 개발 적지가 아닌 것으로 판명되면서 사회적 비용이 낭비될 우려가 있다. 산림청에서는 이러한 문제점을 해결하고자 대축척의 산지구분도를 구축하여 '09년부터 산지정보시스템으로 서비스하고 있다. 산지관리 업무를 기존의 단 방향적이며 정적인 C/S 기반에서 개방과 참여를 중시하는 웹 2.0 기반으로 개편한 것이다. 산림청에서는 서비스하는 산지 정보 변화 내역 모니터링 등 시스템 유지 관리를 통해 최신 산지 정보를 제공하는 한편 사용자 편의성도 지속적으로 강화할 계획이다.

In recently, researches which appling satellite image are introduced target to the forest area. Especially, it is satellite image analysis's advantage that collecting information of terrain at the direct accesses are dangerous and impassible area. But, the studies approaching to a inflectional paradigm of forests and change detection system for the distinguished forests type are leaves much to be desired. In this study, therefore, change of forests type was analyzed using Landsat TM satellite image which have multi-spectral bands. Furthermore, change detection system for forests type was constructed on web for the periodical monitoring.

국토가 좁은 반면 산지가 많은 우리나라에서는 국가지리정보체계 관리 또는 산림자원의 개발과 보전에 대한 중요성이 매우 크다. 따라서 최근에는 산림지역을 대상으로 한 인공위성 영상의 활용 연구가 소개되고 있다. 위성영상은 지구자원의 탐사와 환경감시를 비롯하여 지형정보의 수집 및 분석 등 다양한 분야에서 높은 활용도를 보이고 있으며, 특히 직접 접근이 불가능하거나 까다로운 지역의 지형지물에 대한 다양한 정보의 취득이 가능하다는 장점을 지니고 있다. 광범위한 지역의 주기적인 정보획득이 가능한 인공위성 영상은 환경탐사분야에서 새로운 대안으로 받아들여지고 있으며, 산림분석에도 활용될 수 있다. 따라서, 본 연구에서는 식생분류에 유리한 다중분광센서를 가진 Landsat TM 위성영상을 이용하여 산림형태의 변화를 분석하였으며, 이를 주기적으로 모니터링 할 수 있도록 Web 상에 구축하였다. 이를 통하여 누구나 쉽게 넓은 대상지역 산림형태의 주기적 변화를 모니터링 할 수 있으며, 또한 현장조사 자료의 보완에도 효율적으로 사용될 수 있으리라 판단된다.

Recent development of geographic information systems(GIS) provides a great deal of potential in handling a variety of spatial data required by forest resource managers. This study is designed to identify a possible GIS application in forest pest management. Several mountain pine beetle risk assessment parameters(stand characteristics, weather conditions, and topographic factor) were spatially analyzed through computer map overlaying operations in order to estimate the hazard level of the pest damage. In addition, the expected infestation route from an initially infected forest stand was located through further may analysis operations(distance measurement and connectivity analysis). Although current GIS technology may have a few limitations in operational situations, the computer based GIS has been proven as an invaluable tool to resource managers by providing flexible spatial data handing capabilities.

It is not an easy task for forest managers to make sound decisions on forest management and operations planning because of huge sets of spatial and temporal data and complex decision-making processes involved. However, as an efficient tool, GIS techniques enable them to enhance broad understandings on forest inventory and management conditions. In this study, we developed a GIS model for field use in forest management. In building the model, we have chosen MapInfo version 4.0 as the basic engine of the model. The model also includes an interface module to help forest managers use MapInfo functions easily. It handles MapInfo functions required to manage inventory data and analyze spatial distributions of forest stands. For testing field applicability of the model, we have build field data sets for a district of Chunchun National Forest. Then, we tested functions through quarrying stand attributes and constructing thematic maps. In this paper, the structures and functions of the model as well as the results of field applications are discussed.

A forest functions classification map is an essential element for the management planning of national forests. This study was intended to make out the map at the stand level by utilizing the Forest Functions Evaluation Program(FFEP), developed by Korea Forest Research Institute. In this program, the potential of each function was evaluated in each grid cell, and then a forest functions estimation map was generated based on the optimum grid cell values in each sub-compartment unit. Finally, the program produced a forest functions classification map with consideration of the priority of the functions. The final forest functions classification map required for the national forest management planning made out overlapping those results which the rest of the forest classified referring priority functions classification map to national forest manager and classified according to the local administrative guidance and sustainable forest resources management guidance. The results indicated that the forest function classification using the FFEP program could be an efficient tool for providing the data required for national forest management planning. Also this study made a meaningful progress in the forest function classification by considering the local forest administrative guidance and sustainable forest resources management guidance.
