China's loessland is the home of ancient China's civilisation. For thousands of years, a distinct form of dwelling in Shaanxi, a part of China's loessland has been caves burrowed out of the soil. People still prefer living in cave dwellings to free standing Chinese houses. The persistence of cave dwellings may be an indication that the traditional cave dwellings has been a successful ecological adaptation to the local loess environment with long severe winters and intense summer heat. 相似文献

The Middle to Late Eocene Mangahewa Formation of Taranaki Basin, New Zealand, has been evaluated in terms of organic matter abundance, type, thermal maturity, burial history, and hydrocarbon generation potential. Mangahewa Formation reflects the deposition of marine, marginal marine, shallow marine, and terrestrial strata due to alternative transgressive and regressive episodes in Taranaki Basin. The sediments of the Mangahewa Formation contain type II (oil prone), types II–III (oil-gas prone), and type III kerogens (gas prone), with hydrogen index values ranging from 58 to 490 mg HC/g total organic content (TOC). Vitrinite reflectance data ranging between 0.55 and 0.8 %Ro shows that the Mangahewa Formation is ranging from immature to mostly mature stages for hydrocarbon generation. Burial history and hydrocarbon generation modeling have been applied for two wells in the study area. The models have been interpreted that Mangahewa Formation generated oil in the Mid Miocene and gas during Middle to Late Miocene times. Interpretations of the burial models confirm that hydrocarbons of Mangahewa Formation have not yet attained peak generation and are still being expelled from the source rock to present. 相似文献

The French Renaissance gardens and Japanese hill gardens have constrasting garden landscapes. Japanese gardens are naturalistic and intend to give illusions that they are the beautiful spots of unspoilt nature. In contrast, the appearances of French gardens are not an imitation of nature but boldly reorganised landscapes in geometric forms. These two contrasting types of garden landscapes represent two different sets of geomentalities (frames of mind regarding geographical environment).An earlier draft of this paper was presented at the Ninth New Zealand International Conference on Asian Studies, Hamilton, 23–26 August 1991. Its abridged version is published in D. Bing and K. Henshell (ed.)Japanese Perceptions of Nature and the Natural Order (Hamilton, NZ 1992), pp. 1–11. The present paper was developed from the first half of the conference paper, and was completed during my three month's tenure in 1993 as a Japan Foundation fellow. I am grateful to the Japan Foundation for their generous support of my research on the Japanese geomentality. 相似文献

During CREAMS expeditions, fCO2 for surface waters was measured continuously along the cruise tracks. The fCO2 in surface waters in summer varied in the range 320–440 μatm, showing moderate supersaturation with respect to atmospheric
CO2. In winter, however, fCO2 showed under-saturation of CO2 in most of the area, while varying in a much wider range from 180 to 520 μatm. Some very high fCO2 values observed in the northern East Sea (Japan Sea) appeared to be associated with the intensive convection system developed
in the area. A gas-exchange model was developed for describing the annual variation of fCO2 and for estimating the annual flux of CO2 at the air-sea interface. The model incorporated annual variations in SST, the thickness of the mixed layer, gas exchange
associated with wind velocity, biological activity and atmospheric concentration of CO2. The model shows that the East Sea releases CO2 into the atmosphere from June to September, and absorbs CO2 during the rest of the year, from October through May. The net annual CO2 flux at the air-sea interface was estimated to be 0.032 (±0.012) Gt-C per year from the atmosphere into the East Sea. Water
column chemistry shows penetration of CO2 into the whole water column, supporting a short turnover time for deep waters in the East Sea.
