휴양공간(休養空間)의 환경특성(環境特性)과 이용자의 행동(行動) 및 인지반응(認知反應)과의 상호관계를 밝혀, 자연지역에 존재하는 다양(多樣)한 이용 공간에 대한 휴양(休養) 평가(評價)를 실시하였다. 본 연구는 일본(日本) 대판부(大阪府)의 자연공원내(自然公園內)에 있는 수림(樹林), 수변공간(水邊空間), 자유광장(自由廣場) 및 기타 휴양시설(休養施設)들을 연구대상 공간으로 설정하고, 현지 이용자에 대한 직접(直接) 설문 조사를 실시하여 얻어진 정보를 분석한 연구 결과는 다음과 같다. 1) 수림(樹林)과 수변공간(水邊空間)은 야외 휴양 공간의 기본적 구성요소인 것으로 판단된다. 수림은 임층구성(林層構成)에 따라 휴양 평가의 차이가 있다. 특히 활엽수림(闊葉樹林)은 그 효용성이 높은 것으로 나타났다. 2) 자유광장(自由廣場)은 활용성이 광범위한 휴양 공간이지만 이용 형태에 대응한 공간규모나 지형 등을 설정하여야 하며, 지피식물(地被植物)의 도입과 철저한 관리가 요청된다. 3) 야외 휴양 공간내의 인공시설(人工施設)(전망대(展望臺), 곤충관(昆蟲館), 캠프장(場))은 휴양적(休養的) 평가치(評價値)가 낮은 것으로 나타났으나 다양한 이용성이 있으므로 야외 휴양 활동에 반드시 필요한 것으로 생각된다. 다만 그 설치에 있어서 주변의 자연경관(自然景觀)과 환경용량(環境容量)을 신중히 고려하여야 한다. 4) 전통적인 역사(歷史), 문화시설(文化施設)도 야외 휴양자원의 귀중한 구성요소가 되고 있음이 인정됨으로 이에 대한 지속적인 보전 대책이 강구되어야 할 것이다.

We extracted narrow open water streams from JERS-1 SAR images of the Amazon rain forest. The extracted range of these streams were almost comparable to a high level extraction of the same streams from near-IR images of JERS-1 VNIR data notwithstanding that these features in SAR images show the strong dependence of the observation angle. Large water bodies are relatively easy to extract from JERS-1 SAR images, as they tend to appear as very dark areas; but streams whose width is nearly equal to or less than the spatial resolution no longer appear as very dark features. By using strong scatterers distributed sparsely along the radar facing sides of the streams, we can successfully estimate approximate ranges of waterways and then extract relatively dark line-like features within these ranges.

^x In Korea, we are entering on a new phase that the use concept of urban park is extending to dynamic activities such as games and sports. This article is to investigate the significance of lawn areas, as a receptive space of such a wide range of recreation activities. As a study process, Green Styles (type of parks) such as Garden Type, Park Type and Forest Type were studied and historical review of lawn areas in park development was performed. In conclusion, the lawn areas ( greensward) are an essential part of park and open space organization. The significance as a conclusion is presented as follows : 1 ) Balance in type of parks The structures of our parks and open spaces are inclined toward the artificial Garden Type and natural Forest Type. Therefore, the intermediate Park Type and sparse wood areas should be a core part of our park and open space development. 2) Psychological effect Park Type areas, thorned by greensward(lawn area), can refresh urban dwellers with natural picturesque landscaps, and Park Type landscape is the most preferred natural landscape. It shows the essence of natural amenity as 3) Accomodation of wide range of recreation activities Lawn areas in urban park are the best place in accomodating the wide range of active and massive recreation activities. Thus, lawn areas can increase the freedom of recreation use in urban park. 4) Enlargement of physical carrying capacity. With expansion of lawn areas of euro- american concept, the structural open space can be transformed into service open space. Thus, the recreation carrying capacity of urban parks can be enlarged.

The purpose of this study is to develop means to apply GIS and remote sensing technology to the analysis of Korean urban open spaces. To achieve this objective, a framework of analysis of urban open spaces was developed, and then the framework was applied for the evaluation of the potential and suitability of open spaces of Ansan City, which is a new town developed to accomodate industries relocation from Seoul, Korea, mainly due to their pollution problems. The software used in this study are IDRISI, a grid-based GIS, and KMIPS, a remote sensing analysis system. Both packages are based on IBM PC/AT computers with Microsoft DOS. Landsat MSS and TM data were used for the land use classification, land use change detection, and analysis of transformed vegetation indices. The size of the geographic data base is 110 rows and 150 columns with the spatial resolution of 100m$\times$100m. The framework of analysis includes both quanititative and qualitative analysis of open spaces. The quantitative analysis includes size and distribution of open spaces, urban develpment of open spaces, and the degree of vegree of vegetation removal of the study area. The qualitative analysis includes evaluative criteria for primary productivity of land, park use potential, major visual resources, and urban environmental control. The findings of this study can be summarized as follows. First, the size of builtup areas increased 18.73km$^2$, while the size of forest land decreased 10.86km$^2$ during last ten years. Agricultural lands maintained its size, but shifted toward outside of the city into forest. Second, the potential of open spaces for park use is limited mainly due to their lack of accessibility and connectivity among open spaces, in spite of ample acreage and good site conditions. Third, major landscape elements and historic sites should be connected to the open space system of the city by new accesses and buffers.

In this study 'forest design in waterside unused land' of 'waterside area' in the specificity that multilateral, including landscape, recreation, social and environmental aspects in the space, taking into account by multiple factors :Raise 'practicality' than a functional management and police to hang out with, each element is usually way to improve the beauty. There is currently carried out waterside green area creation, which is artificial plantation and open spaces only emphasizing 'landscape' with lacking multi-function purpose, as a 'forest design in waterside unused land' strategy but it should be lowered by performance in this strategy. And the study suggested a strategy which prepared cultural and social infrastructure to be able to attract different fund and build local character as an alternative demand plan considered environmental character as a top priority.

Microclimate of open spaces on campus tends to be important because it is related with people's comfort and it can influences their behaviors in outdoor during summer. Climatic components for 4 points, concrete paving, lawn, landscaped pergola and nearby forest on university campus were measured and evaluated. The results show that the air temperatures on paving such as concrete and lawn under the direct solar radiation were higher than the temperatures of canopied spaces such as pergora and nearby forest by up to $7^{\circ}C$ during summer. Characteristics of temperatures on lawn were similar to those on concrete paving. After evaluation, concrete surface was worst among 4 points, while landscaped pergola was the most effective facility in terms of thermal comfort during summer.

The current study aimed to investigate the impact of CO₂ enrichment on the width of annual tree rings, earlywood and latewood, and the area of annual growth of Pinus densiflora Siebold & Zucc. grown in open-top chamber (OTC). To this end, two CO₂ enrichment cases were considered, namely 1.4 × increment (560 ppm in OTC-II) and 1.8 × (720 ppm in OTC-III) were compared with the current atmosphere (400 ppm in OTC-I). The CO₂ enrichment conditions for a period of 12 years (2010-2021) were considered, and all measurements were done through image analysis. The study showed that the increment in CO₂ concentrations positively affected the tree growth. The measurement data from the trees in OTC-III were considerably higher than those from OTC-I, whereas those from OTC-II were slightly higher than those from OTC-I. Decreasing patterns of the measured widths and area in 6-7 years after the beginning of CO₂ enrichment was found for all the OTCs. These patterns were possibly due to changes in the physiological features, such as aging. The findings of the present study can have potential uses as fundamental data for forest management considering CO₂ concentrations.

최근 들어 contingent valuation method는 산림휴양자원과 같은 비시장재(非市場財)(nonmarket goods)의 경제적 가치평가에 널리 이용되고 있다. 이 방법에는 개방형(open-ended) 질문과 폐쇄형(closed-ended) 질문이 사용되어지는데, 어느 것이 경제적 가치를 적절히 평가하느냐에 관한 결론적 증거는 없다. 따라서 본 연구는 최근 산림휴양활동중 그 수요가 급격히 증가하는 겨울철 야외스포츠인 스키를 사례로 하여 무주리조트 스키장의 방문객들에게 개방형과 폐쇄형질문을 실시하여 두 설문기법간의 추정결과에 차이가 있는 지를 비모수적검정(非母數的檢定)(nonparametric test)을 통하여 검토하고자 수행되었다. 지금까지 외국에서 개발된 여러 비시장재(非市場財)의 가치평가 모형을 적용하여 경제적 가치를 계량화(計量化)한 결과, 무주리조트 스키장을 이용하는 방문자 한 사람당 순경제적편익(純經濟的便益)은 15,131원에서 25,332원까지 나타났으며, 폐쇄형질문을 적용한 순경제적가치(純經濟的價値)가 개방형질문보다도 약 1.15배에서 1.67배까지 높게 나타났다. 비모수적검정(非母數的檢定) 결과 두 질문형태간에는 유의성이 있는 것으로 나타났다. 그 이유로는 폐쇄형질문이 개방형질문보다 전략적 편의(strategic behavior bias)의 발생을 줄일 수 있는 것으로 사료되나, 본 연구 결과로서는 폐쇄형 질문이 개방형 질문보다 더 효율적이라는 증거는 찾을 수 없었다. 따라서 contingent valuation을 이용하여 비시장재(非市場財)의 경제적 가치를 측정할 경우, 이 두 가지의 질문형태를 함께 고려하여 경제적 가치를 결정해야할 것으로 판단된다.

Calibration experiments were executed to document pertinent calibration methods for open-path infrared gas analyzer (OP-2) in field operations and to quantify their performance characteristics in continuous long-term flux measurements. Based on our results, we concluded: (1) flow rate of 2.0 L min$^{-1}$ can be used for calibration instead of the recommended 0.5 L min$^{-1}$ . Such faster flow rate brings the sampled air in the calibration hood at equilibrium within 5 min for $CO_2$ and 10 min for $H_2O$; (2) after reaching equilibrium, two-minute average sampling for related variables per each concentration may be sufficient; (3) use of four concentration is needed to derive the nonlinear calibration equation for water vapor with 1% uncertainty of flux measurement; and (4) the resultant calibration interval for OP-2 for both $CO_2$ and $H_2O$ is approximately one month.
