해풍은 육풍에 비해 더 높은 풍속, 염도, 습도를 가졌을 뿐 아니라 풍향의 전환도 빠른 특성을 갖고 있다. 수목의 초기 생장에 영향을 끼치는 주요한 인자중 하나는 풍속이며, 일반적으로 초기 생장단계에서 수목의 생장률은 풍속이 감소될수록 증가하는 특성을 가진다. 따라서, 본 연구는 새만금 방조제에서 방풍시설을 설치함에 따라 수목의 생장과 해풍의 특성을 확인하기 위해 수행되었다. 본 연구에서는 폴리에틸렌 재질의 방풍시설(개구율 40%)이 높이 3m, 길이 130m에 걸쳐 설치되었으며, 내외부에 1, 2, 3m 높이의 풍향풍속계를 5대 설치하여 2011년부터 2012년까지 1분 간격으로 수집하였다. 새만금 방조제 시험지의 풍향 빈도는 북풍이 26.8%, 북서풍 20.3%, 북동풍 14.6% 순으로 나타났으며, 풍속은 높이별로 다르게 나타났다. 해송의 생장은 방풍시설 내부에서 자라는 경우가 외부에서 자라는 경우에 비해 수고 약 17%, 근원경 약 13% 높게 생장한 것으로 나타났다.

We present a planting plan of the buffer-forest belts created at the boundary area of the waste landfill site which is located in the coastal area of Kyubg-Gi province. In order to form a proper section of ground soil excavated from the sea and a forest which shows a distinction of the vegetation stratification, the planting plan with trees, sub-trees, shrubs, and seedlings (produced at a sprout cultivation place) is devised with an adjustment of planting density. 1. The preparation of mounding is required for planting at a waste landfill site. We first estimate an economical and efficient banking height together with the quantity of soil, and prepare a planting ground with excavated ground soil for the consideration of soil recycling. On the planting ground a banking with a height of 1.5-2m is produced by self-supported soil, playing a role in a salt blocking and an irritation layer of planting. Finally, an additional banking with a height of 2m is produced by qualified vegetation soil, forming a vegetation section with a total height of 6m. 2. Since the planning site is located in the border, the planting area is composed of two regions : one is an inclined face (slope 1 : 3) toward the inside of the landfill site and the other is an inclined face (slope 1 : 4) toward the inland. The buffer planting in the former (latter) region consists of wind break forest (mixed-landscape forest) within a width of less than 35m. 3. Based on the data obtained from the literatures and the investigation of local plants, we choose the 21 plant species (such as Pinus thunbergii, Pinus densiflora, Sorbus alnifolia, Albizzia julibrissin and etc.) and the additinal 7 species which are grown at a sprout cultivation palce of the SUDOKWON landfill site (Rosa rugosa, Quercus acutissima, Prunus armeniaca var. ansu., and etc.). Sub-trees with a height of above 2.5m and seedlings are planted with an interval of $1.5{\times}1.5m$ ($0.45roots/m^2$) and $0.5{\times}0.5m$ ($4roots/m^2$), respectively. Here, both trees exhibit communities planting with more than three rows. Shrubs are planted with $9-16roots/m^2$, depending on their size. Since this case study provides a reference of the planting beds as well as a planting plan at the SUDOKWON landfill site, it is not sufficient for the present plan to be utilized for the formation of buffer-forest belts which are used for the analysis of environmental factor and the reduction of environmental pollutants in the sea waste landfill site. Thus, further studies with the ecological basis are demanded for the environment planting restoration in the sea waste landfill site.

This paper contains the results obtained by the ecological investigation in Bijin island. The investigation was conducted during 3 dyas from Aug. 3 to Aug. 5, 1981. The results are followings. The tracheophyta of this island was recoreded as 64 families, 128 genera, 142 species, 21 varieties and 2 forma. Twenty eight species of ever-green broad-leaved trees comprising Gardenia jasminoides for. grandiflora, Castanopsis cuspidata var. thunbergii, Camellia japonica, etc. wad distributed in the southern area of the island. And there was the wind-break forest mainly consisting of aged Machilus thunbergii, Celtis sinensis and Zelkova serrata in the northern area. The northern area dominated by the second forest of Pinus thunbergii, where the whole residents lead their lives, shows the high population density and pure farming rate, so the natural degree is low. The other hand, there was the well-preserved forest of broad-leaved trees containing Zelkoba serrata. Acer palmatum and Quercus serrata, etc. in southern area having a steep peak, Seonyudai, and no resident. So, the potential vegetation of this island is assumed as the forest of ever-green broad-leaved trees which belongs to the forest of subtropics.

This study was carried out to the development of ecological planting model to make up of coastal windbreak forest on the Suncheon-bay in Sucheon-si, Korea. Make up of coastal windbreak forest in this site was needed for appropriate bioresource, biodiversity and ecological structure, and for conservation of the eco-tour resource and protection of human life and property by the unforeseen disaster from the coast. Based on the plant-social principle, the planting model of windbreak forest was developed to facilitate growth of trees, considering planting locations. The ecological planting model for the coastal windbreak was composed of warm temperate evergreen and windbreak forest which is spreading around the inland area in Korea. The horizontal forest style was composed of forest edge community and inner forest community, and the vertical forest style was composed of upper, middle, low and ground planting class. The target of the present model was quasi-natural forest, and the species of tree were selected based on the adaptability to surroundings depending on a goal to create a forest and forest style. To achieve both functions of wind break forest and visual effect in short period of time, small trees and seedlings were planted with high-density of 40,000/ha in an expectation of easy natural maintenance in the future. The significance of the present study is a suggestion for a guideline to create ecological coastal windbreak forest in the Suncheon-bay in which the harmony of human life and the ecological conservation is of great importance. Also, the ecological coastal windbreak forest model should be developed further through the long term monitoring after construction of forest.

Hsinchu Science Park, one of the most productive electronic sites in the world, is located at Hsinchu County. Hsinchu County Government is entitled for daily management to pursue the objectives of making every county citizen prosperous. Several web-based management information systems have been developed for county management and were widely implemented. However, forest management is one of several tasks which need development of web-based geographic information systems. The objectives of this paper are to develop GIS for forest management at Hsinchu County in order to solve problems encountered in the rapid changing circumstance. The objectives of forest management at Hsinchu County have been changed a little bit in the last decade. Now, it mainly focuses on public and private forest, tree planting, wind break forest management, and plane forest planting. The major ingredients of GIS for forest management are user-friendly, task-oriented, and direct linking to the existing GIS at Hsinchu County. AreIMS and ArcGIS were used for web-based GIS. Field operations of forest management depend on PDA and GPS such that ArcPAD is implemented both on personal computers and PDA. Computer programming is required for database management and development of application modules in forest management. Color digital orthophoto maps at scale of 1:5000 provide very useful background information. Forest management at Hsinchu County now is operated in an efficient way that GIS, remote sensing, GPS and PDA are working smoothly.

Status of agriculture in Jeju province were investigated to find out problems and solutions in view of weather, soils and crop productions. Two hundred harmful windy days per year force to build strong wind-break forest near to farm. Somewhat severe drought situation in croping could be completely avoided by good irrigation system using abundant underground water resources. Poor fertility of soils should be improved by using much compost, lime, fused phosphate, and high dose fertilizers. Optimum fertilizer level for each crop should be determined with special consideration on characteristics of volcanic ash soil.

본 연구는 통영 수월숲의 인문학적 특성과 자연생태적 특성을 바탕으로 효율적인 보존 관리방안을 제안하기 위해 진행하였다. 김해김씨 서암파 문중 소유인 대상지는 약 1,000년 전 태풍에 대비하여 농작물을 보호하고자 조성한 숲으로 1960년까지 동신제를 지내는 등 양호하게 보호 관리되어 왔었다. 방풍림의 면적은 $12,392.69m^2$로 느티나무, 팽나무, 푸조나무 등 낙엽활엽수 노거수가 우점종이었으며 주변은 경작지(52.1%), 도시화지역(26.3%), 산림지역(16.6%)으로 둘러싸여 있었다. 우점종 및 이용압을 고려하여 군집을 분류한 결과, 이용압이 낮은 푸조나무군락(I), 굴피나무-소사나무-느티나무군락(II), 이용압이 높은 느티나무군락(III), 느티나무-푸조나무군락(IV), 이용에 의해 하층이 훼손된 느티나무군락(V)으로 구분되었다. 방풍림의 보존상태는 양호하나 과거 잘못된 마을숲 복원 사업, 내부를 관통하는 산책로, 교육장 설치 등으로 인해 훼손의 우려가 있었다. 따라서 수월숲 고유의 가치를 복원하기 위해서는 개발에 의한 숲 변화, 이용압에 의한 훼손, 관리부재로 인한 쇠퇴현상을 개선해야 할 것이다. 이용압에 의한 훼손을 방지하기 위해서는 과도한 휴게시설 철거와 정적이고 소극적인 이용을 유도해야 하고, 개발에 의한 숲 변화를 막기 위해서는 우회로를 설정한 후 관통도로를 폐쇄하는 것이, 관리부재로 인한 쇠퇴현상 개선을 위해서는 현명한 이용을 전제로 차대목 육성과 하층식생 복원이 필요하였다. 차대목은 숲내 우점종인 느티나무, 팽나무, 푸조나무, 이팝나무 등을 모수로 실생묘를 육성 도입하여 식생 및 원형경관을 회복해야 할 것이다. 하층식생 훼손지역 복원을 위해 훼손지와 양호한 식생군락을 비교한 결과 아교목층은 10.8개체, 관목층은 79.7개체 차이가 나므로 부족분을 보완식재해야 할 것이다.
