Pollen analysis of moor peat of Daeam Mountain revealed vegetational history around Daeam Mountain. The pollen stratigraphy might be zoned into three, Zone I, Zone II and Zone III for the past 2, 200 years. The time required for amount of the accumulated peat in the moor was estimated in terms of the balance of the accumulation and decay of organic carbon of the deposit peat. Zone I(770~2, 200 yr BP) had Pinus and Quercus as main elements. Gramineae decreased while Typhaceae, Cyperaceae and spores such as Polypodiaceae increased. Zone II(300~770 yr BP) showed warming trend which is suggested by high pollen concentrations of Quercus, Juglans, Carpinus, Ulmus and by a more diverse flora of deciduous borad-leaved trees than Zone I. Pinus decreased in this zone. It suggests that the overall environment became milder than Zones I and III. Zone III(earlier than 300 yt BP) was predominantly Quercu and Pinus with amount of nonarboreal species such as Artemisia, Gramineae and Chenopodiaceae, that was grown under dry conditions. It suggests that overall environment vecome humid by comparison with the present time and it is surmised the course of boggy ground formation by a retrogressive succession.

Many models intending to explain the latitudinal gradient of increasing species diversity from the poles to the equator are presented, which are a formalisation of the species-energy hypothesis. The model predictions are consistent with patterns of increasing species number with increasing mean air or water temperatures for plants and animals. An increase in species richness is also correlated with net primary production or the Normalised Difference Vegetation Index. This implies that increased availability of resources favours increased diversity capacity. The explanatory variables included in the biodiversity prediction models represent measures of water, energy, water-energy, habitat, history/evolution and biological responses. Water variables tend to be the best predictors when the geographic scope of the data is restricted to tropical and subtropical areas, whereas water-energy variables dominate when colder areas are included. In major models, about 20-35% of species in the various global regions (European, Africa, etc.) will disappear from each grid cell by 2050 and >50% could be vulnerable or threatened by 2080. This study provides good explanations for predictive models and future changes in biodiversity depending on various scenarios.

This paper is performed to study for the plants ecosystems for the rural community forest of designated as natural monument. In addition, it is also proposed the plan of the rural community forest's conservation and restoration for avoiding to the destroy of indiscriminate development such as land-use, cultivation. The rural community forest is a mirror that reflect the regional culture and history, as well as environment. According to this view, undoubtedly, we need to recognise the formative background of rural community forest, the relations between the environment around and the characteristic of plants ecosystem comprehensively. For the purpose of proposing to the plan of rural village forests' conservation and restoration, therefore, this study is: 1) reviews the previous research and ancient documents, and 2) surveys the vegetation structure and the growing conditions in rural village forest directly.

일본 남서부 大田市(Ohda-city)일대의 식생변화와 Lake Shinji에서 보고된 화분분대를 대비하기 위해 피근호(Lake Hane) 퇴적물의 화분분석을 실시하였다. OH94 코어시료(19.7 m)의 화분분석결과, 하부로부터 Cyclobalanopsis-Catanopsis 화분대와, Gramineae 화분대로 나누어진다. Cyclcbalanopsis-Catanopis 화분대는 Cyclobalanopsis아대, Catanopsis아대 그리고, Podocarpus아대로 세분할 수 있고, Gramineae 화분대는 Cryptomeria아대와 Cyclobalanopsis-Quercus아대로 세분된다. 특히 Cyclobalanopsis-Cutanopsis 화분대에서 K-Ah 테프라를 동정하였고, 이 결과로부터 Cyclobalanopsis-Catanopsis 화분대가 $6,300_{14}$CBP이전부터 시작되었음을 알 수 있었다.

In recent Japan, the demand for woodland creation on revegetation sites is increasing. In the forests and woodlands, we can find many functions of environmental conservation, in addition of biomaterial production, and all of these existences with such functions are defined as environmental woodlands. Many woodlands has been created from old times for the purpose of forest conservation and flood control, and most of these technology are handed down to present time. After Edo era (from the beginning of Meiji era, 1867), some valuable examples of woodlands were created, like Meiji shrine woodland in Tokyo. After the World War II, a lot of technology for woodland revegetation, such as ecological tree planting, have been developed. At present, many revegetation sites are aiming at woodland creation, like on man-made slope, etc.. In the great change of social structure, revegetation technology is also required to keep in close relationships to the restoration of devastated existing forests and woodlands, and to provide many technology for the restoration of secondary woodland, preservation of soil, mitigation, reclamation, etc.. Now in Japan, the improvement of environment including all the member of biosphere is demanded on a large scale. Therefore, revegetation technology should also try to make an activity taking a broad view of the restoration of natural vegetation in addition to the traditional and new woodland creation.

The Okjukdong dune in Daecheong Island attracts national attention because of its unique landscape that is not covered by vegetation. However, there has been little knowledge on the timing of the dune formation, associated wind regime, and conservational strategies. In this study, we used OSL dating and grain size analyses to reveal the history of the dune development. In addition, we analyzed the wind regime in the dunefield which is surrounded by artificial coastal forest. The fine sand at Okjukdong underlain by a colluvial gravel layer indicates that the dune has been developed since at least 5 ka. Aeolian sands were found to be deposited around 700 years ago. The dunefield appears to have been severely eroded 30~60 years ago. The dune landscape has been destroyed after constructing a windbreak forest around the dunefield. The sand seems to be moving south and north with the season.

무안군 피서리 유적지에 노출된 후기 제4기층에서 포자$\cdot$화분 분석결과，낙엽성 활엽수　화분이 주종을 이루고 있으며 초본류와 침엽수 화분도 풍부하게 산출되었다. 대표적인 종류로는 고란초과, 낙우송과-측백과-주목과, 오리나무속, 서어나무속, 낙엽성 참나무속, 국화과 및 벼과 등이다. 탄소연대측정 결과, 그 생성 시기가 지난 최후 빙하기에 해당하는 43,000-18,000 yr BP 로 측정된 이 포자$\cdot$화분군은 오늘날 한반도 중부의 한랭한 온대 낙엽성 활엽수림의 식생과 유사하다. 전체적인 식생 조성에 근거하여 3개의 포자$\cdot$화분 분대를 설정하였다. Zone I은 고란초과, 낙우송과-측백과-주목과, 오리나무속 및 낙엽성 나무속 등으로 이루어진 한랭한 온대의 낙엽성 활엽수림을 지시하며 특징적으로 난대종이 지속적으로 산출된다. Zone II에서는 고란초과와 낙우송과-측백과-주목과 등이 뚜렷하게 감소하고 초본류가 증가하는 양상을 보이는데 이는 당시에 한랭한 온대의 낙엽성 활엽수림과 함께 부분적으로 초지가 분포했음을 의미한다. Zone III에서는 초본류의 지속적인 산출과 함께 침엽수가 증가하는 경향을 보인다. 피서리 포자·화분군의 식생 조성은당시의 기후가 한랭한 온대였다는 것을 지시하며 시간이 흐르면서 점차 한랭·건조해진 것으로 해석된다.

It is possible to divide the historical changes of slope revegetation in Japan into five periods as follows; 1) The early period after creation(1927-1948), 2) The spreading period of modern revegetation work with manpower(1947-1958), 3) The spreading period of rapid revegetation technique using exotic grasses with machineries(1959-1985${\dots}$), 4) The spreading period of rapid reforestation technique by fast growing species mainly using leguminous shrub species(1986-1995${\dots}$), 5) The developing period of nature restoration technique using endemic arborous species(1996-). Recently main purpose of slope revegetation has been developing from the erosion protection to the nature restoration in the current of the 5th period. It is said that the role of the Japanese Society of Revegetation Technology(JSRT) is critical to the history of slope revegetation in Japan. 'The tentative guidelines of slope nature restoration' was announced by JSRT in 2004. In the guidelines, it was proposed that the planning techniques of using suitable seeds/plants based on the preservation level at the each construction sites. Moreover, the use of soil seed bank is the new and important study theme in the field of nature restoration. Consequently, at present the importance of advanced monitoring methods for vegetation maintenance and plant sociologic survey to evaluate the plant succession is increasing. Finally, some critical concepts are necessary to develop the field of restoration in Korea as follows; 1) monitoring of constructed sites, 2) ensuring of biodiversity, 3) recognition of slow revegetation and mosaic arrangement in revegetation, 4) reuse and recycle on the construction sites, and 5) promotion of specialist.
