  • A bridge is a space used as a passage. This space should be functional, solid, and beautiful. Since the beginning of human life, bridge architecture has given importance to function as a connection from one place to another. Stepping stones in the stream were the connections between divided spaces in the agricultural life, the bridge on the entrances of a town was the place for separation, expectation, and communication for people gathering around the community. Southern Chinese provinces such as Zhejiang, Hunan, Yunnan, and Guizhon is famous for it's spectacular scenary, and tribes like the 'Miao' and 'Dong' live in a cooperate community. The 'Dong' tribe is one of the 'Yue' genealogy where the people have settled down in this place in the days of 'Qin Shi Huang(Qin dynasty)'. As the population of the 'Dong' tribe growed, they used a bridge to connect town to town. The scale became larger with additional design, giving splendid achievement to bridge architecture. The 'Fungyu bridge' in Tongdao and 'Chungyang bridge' in Sanjiang are some fine examples. The Fungyu bridge could be defined as a bridge which blocks wind and rain, this has the same function as the lounge bridge in Taishun located in southern Zhejiang province. In Taishun, 5 minority races such as the 'Dong' and 'Miao' people have been living together as a clan society for centuries on mountains as high as 1000m following their own tradition. The 'Xiliu river' flowing thorough has a variety of bridges remaining in it's original form, and it is recently known as a museum of ancient bridges. The formation of the bridges in Tongdao and Taishun shows that it is different with the arch and straight bridges remaining in Korea. In this study, it is readjusting the base data, showing plan characteristics and describing the construction of the wooden structure above the bridge post.

  • The vascular plants in Baekdudaegan of the South Korea were recorded of 1,477 taxa; 126 families, 641 genus, 1,248 species, 3 subspecies, 204 varieties, 22 forma. From the floristic point of view, Jirisan, Backunsan and Duckyusan District in the Baekdudaegan belongs to the southern province in Korea, appeared to Cephalotaxus koreana, Lindera obtusiloba, Lindera erythrocarpa, Lindera glauca, Izex macropoda, Meliosma myriantha, Melisoma oldhami and Stewartia koreana. But on the top regions of these mountains more than 1,000m above the sea level were contained many alpine plants. And on the top regions and ridgeline parts of Duckyusan and Jirisan were the middle province, owing to Betula costata, Betula ermani, Ulmus laciniata, Isopyrum raddeanum, Hylomecon vemale, Viola diamantica, Vaccinium koreanum, Heloniopsis orientalis, Disporum ovale, Symplocarpus renifolius and Veronica arvensis. These results were epresented that plant species of the middle province moved to the South along the ridgeline of Baekdudaegan, on the other hand plants of southern province had biological niche of low ground according to go toward the North.

  • Reconstruction of the past vegetational changes of Korea in connection with climate changes enables to understand the impacts of past and future global warming on alpine vegetation. Despite the early appearance of the cold-tolerant vegetation since the Mesozoic Era. the occurrence of warmth-tolerant vegetation during the Oligocene and Miocene implies that most of alpine and subalpine vegetations have been confined to the alpine and subalpine belts of northern Korean Peninsula. The presence of cold-episodes during the Pleistocene. however. might have caused a general southward and downslope expansions of cold-tolerant alpine and subalpine vegetation. But the climatic warming trend during the Holocene or post-glacial period eventually has isolated cold-tolerant alpine and subalpine vegetation mainly in the northern Korea. but also on scattered high mountains in the southern Korea. The presence of numerous arctic-alpine and alpine plants on the alpine and subalpine belts is mainly due to their relative degree of sensitivity to high summer temperatures. Global warming would cause important changes in species composition and altitudinal distributional pattern. The altitudinal migration of temperate vegetation upward caused by climatic warming would eventually devastate alpine plants.

  • Anhui Province, with a total north-south length of 570km and an east-west width of 450km and a total area of 139.6 thousand km2, accounts for 1.45% of China's total area. The landform and land feature of Anhui Province is diverse, and generally it can be divided into 5 natural regions: (1) Huaibei Plain; (2) Jianghuai Hillocks; (3) Dabie Mountains in the West of Anhui Province; (4) Yanjiang Plain, (5) Mountain Area of southern Anhui Province. Anhui Province is located in the transitional zone of warm and humid zone and subtropical zone, and its mean annual precipitation is 800-1800mm. The province, which has diverse climate, multiple land forms and many rivers and lakes, passes three basins (Huaihe River, Yangtze River and Xin'an River) and has large differences in the time distribution and regional distribution of water resource. Therefore, the development and usage conditions of the water resource in different regions are different.

  • The Bamboo stands, which had been planted for agricultural uses, have been spreading from fields to hills and mountains beyond farmers’ expectation over the last 50 years. Bamboo stands yield bamboo shoots to be served as a vegetable dish (‘takenoko in Japanese’) every spring, and supply materials for bamboo crafts in various ways. Now, as bamboo products have lost their social demand, bamboo stands has been gradually abandoned. This has resulted in the wild and unfavorable spread of bamboo stands in many regions over the western half of Japan. This paper illustrates the unfavorable spread of bamboo stands regionally in the southern Kyoto from 1985 to 1999 and the Yamashiro area from 1948 to 2000 through the observation of satellite images and aerial photographs.

  • This study analyzed distribution of natural disaster and trend of related climatic elements in mountainous region of Gangwon-do. In mountainous region of Gangwon-do, there have been 27 natural disasters of which heavy rainfall have the leading cause for the last 5 years(16 times in 2003-2007). It has been 9 natural disasters in Jinbu-myeon Pyeongchang-gun, the most frequent area. The mountainous region has been larger natural damage than its surrounding regions and there has been more damage at higher altitudes. While the heavy rainfall have caused damage over the northwest of mountains, most typhoons have damaged southern part of mountains. Most mountainous region suffers from strong wind but damage by snow is small. In mountainous region of Gangwon-do, annual precipitation, intensity of precipitation and heavy rainfall days have been increasing since 2000 and this tendency is significant in its intensity. However, annual snowfall, snowfall days and heavy snowfall days have been clearly decreasing since 2000. In case heavy rainfall accompanies strong wind, the damages are larger in mountainous region of Gangwon-do. Therefore it is important to be prepared for heavy rainfall and strong wind.

  • This study aims to find the characteristics of the folk houses in the upper area of Seomjin river in the view point of generating housing floor plans by their human and natural elements of environment. Because they are formed differently as them and have the characteristics as the houses in the upper area of Seomjin river. Seomjin river flows from mid-west area of the Korean peninsula to the southern sea. This is about 212.3km long and the fourth in the south of the Korean peninsula. It is surrounded high mountains in the upper area and makes open field in the mid and lower area of river. The study is surveyed and analyzed to the folk houses of the middle and lower class people in the area of Seomjin river. Because they have been formed by their natural and human elements of environment gradually. They are 35 houses - 13 in Jinan-kun, 4 in Imsil-kun, 10 in Namwon city, 10 in Sunchang-kun. They are analyzed by their floor plans and their spatial relations. The result of this study is that they are made by their natural and human elements of environment. There are some houses with semi-several wings and with storage that are appeared in the mountain village. It reflects that they are surrounded by high mountains. And there are some houses with wooden floor room that are appeared in the area of river little in the area of mountain. To prevent wind from the river the houses are layouted as a form . open ㄴ type, open ㄷ type, and their wall is made of stone and planted bamboo trees around their houses.

  • The hydrocarbon source rock potential of the Eocene units in the southern Oregon Coast Range was evaluated by using the Rock-Eval pyrolysis. Most Eocene units in southern Oregon Coast Range are thermally immature and contain lean, gas-prone Type III kerogen. However, some beds(coals) are sufficiently organic-rich to be sources of biogenic and thermogenic methane discovered in numerous seeps. The overall hydrocarbon source rock potential of the southern Oregon Coast Range is moderately low. Several requirements for commercial accumulations of hydrocarbon, however, probably exist locally within and adjacent areas. Three speculative petroleum systems are identified. The first includes the southern part of the Oregon Coast Range near the border with the Mesozoic Klamath Mountains and is related to a proposed subduction zone maturation mechanism along thrust faults. The second is centered in the northern part of the range and may be associated with basin-centered gas in an over-pressured zone. The third occurs near the eastern border of the range where maturation is related heating by sills and migration of hydrothermal fluids associated with mid-Tertiary volcanism in the Western cascade arc.

  • We investigated the characteristics of meteorological conditions related to the strong downslope wind over the leeward side of the Taebaek Mountains during the period 2005~2010. The days showing the strong wind exceeding $14ms^{-1}$ in Gangwon province were selected as study cases. A total of 15 days of strong wind were observed at Sokcho, Gangneung, Donghae, and Taebaek located over the Yeongdong region. Seven cases related to tropical cyclone (3 cases) and heavy snowfall (2 cases) and heavy rainfall (2 cases) over the Yeongdong region were excluded. To investigate the characteristics of the remaining 8 cases, we used synoptic weather chart, Sokcho radiosonde, Gangneung wind profiler and numerical model. The cases showed no precipitation (or ${\leq}1mm\;day^{-1}$). From the surface and upper level weather chart, we found the pressure distribution of southern high and northern low pattern over the Korean peninsula and warm ridge over the Yeongdong region. Inversion layer (or stable layer) and warm ridge with strong wind were located in about 1~3 km (925~700 hPa) over mountains. The Regional Data Assimilation and Prediction System (RDAPS) indicated that warm core and temperature ridge with horizontal temperature gradient were $0.10{\sim}0.23^{\circ}C\;km^{-1}$ which were located on 850 hPa pressure level above mountaintop. These results were summarized as a forecasting guidance of downslope windstorm in the Yeongdong region.

  • This work aims to select the potentially vulnerable plant species against climate change at alpine and subalpine belts of Mts. Sorak, Jiri, and Halla, from central, southern, southern insular high mountains of the Korean Peninsula, respectively. The selection of global warming related vulnerable plants were performed by adapting various criteria, such as flora, endemicity, rarity, floristically specific and valuable species, species composition at mountain summits, horizontal and vertical ranges of individual species, and their distributional pattern in the Korean Peninsula. Line and quadrat field surveys along the major trails from all directions at height above 1,500 meters above sea level of Mts, Sorak, Jiri and Halla were conducted each year during spring, summer, and autumn from 2010 to 2011. Based upon above mentioned eight criteria, high level of climate change related potentially vulnerable arboral plants, such as Rhododendron aureum, Taxus caespitosa, Pinus pumila, Oplopanax elatus, Vaccinium uliginosum, and Thuja koraiensis are noticed from at subalpine belt of Mt. Sorak. Species of Abies koreana, Rhododendron tschonoskii, Oplopanax elatus, Taxus cuspidata, Picea jezoensis, and Juniperus chinensis var. sargentii belong to climate change concerned vulnerable species at subalpine belt of Mt. Jiri. High level of climate change related species vulnerability is found at alpine and subalpine belts of Mt. Halla from Diapensia lapponica var. obovata, Salix blinii, Empetrum nigrum var. japonicum, Vaccinium uliginosum, Juniperus chinensis var. sargentii, Taxus cuspidata, Rhamnus taquetii, Abies koreana, Hugeria japonica, Prunus buergeriana, and Berberis amurensis var. quelpartensis. Countermeasures to save the global warming vulnerable plants in situ are required.
