自冬至夏
英文
from winter to summer-
Setenaly according to the analyses from selected profiles, we know that, it is cold and dry in this region during the early holocene when east asian winter monsoon ' s influence is obvious, so, it is a transition period from sand deposit to sandy soil deposit, when the layers become thinner gradually from north to south. during middle holocene, it is warm and humid, influenced evidently by east asian summer monsoon, so, it is an obivious pedogenesis, when there are generally well - developped holecene palaeosol ( so ) from north to south, and the pedogenesis in the south is better than that in the north, the soil is also thicker than that of the north. from late holocene to now, the climate changes to be dry and cold, but its changing scope is smaller than that of last glacial period
2 、就所選剖面分析來看，本區在全新世早期氣候回返，相對較寒冷乾燥，東亞冬季風影響較明顯，此時為沙層堆積向砂質土壤過渡，自北至南堆積的沙粒漸細；全新世中期氣候溫暖濕潤，東亞夏季風影響顯著，此時為明顯的成壤期，表現在自北至南普遍可見發育較好的黑壚土層，且南部的成壤作用比北部好，土壤的厚度也要大；全新世晚期至今，氣候向乾冷方向轉化，但變化幅度遠小於末次冰期。The trim hedge, the grass - plot before the door, the little flower - bed bordered with snug box, the woodbine trained up against the wall, and hanging its blossoms about the lattice ; the pot of flowers in the window ; the holly, providently planted about the house, to cheat winter of its dreariness, and to throw in a semblance of green summer to cheer the fireside ; all these bespeak the influence of taste, flowing down from high sources, and pervading the lowest levels of the public mind
宅前樹籬齊整，綠草茵茵，花圃精巧，四周黃楊密植；忍冬緣墻而上，其花綻放，星星點點，綴于窗欞；窗臺飾有盆花，居所四周植有冬青，聊以消解寒冬之孤寂，室內爐火熊熊，雖非夏日，宅前院后綠意濃濃，亦使居者倍感愜意；凡此種種，皆孕高雅之情趣，自紳士名流，至草根百姓，澤被萬民。2. according to the weighted average, soil co2 concentration is 0. 58 - 13. 29 times of that in atmosphere and is relatively lower than similar research, meanwhile, soil co2 concentration in profile varied irregularly, which possibly is due to the chemical and physical characteristic of loess soils, season change and arid climate etc. the variation of soil co2 concentration in profile is mainly controlled by soil temperature and soil moisture, in contrast with soil temperature, the control role of soil moisture is minor. in conclusion, in order to have a good command of the distribution and change rule of soil profile co2 concentration as well as its effect factors, multi - point and successive location experiment should be made, meanwhile establish indoor soil - pillar monitoring experiment
土壤co _ 2的濃度約為大氣co _ 2濃度的0 . 58 ? 13 . 29倍與同類研究相比要低，這是與黃土的土質特性，觀測期又逢特別乾旱年制約了土壤微生物的活動，再加上土壤中有機質虧損，養分不足造成的；土壤co _ 2含量的變化是隨溫度的升高而升高，在夏季達最高值，冬季最低；在土壤co _ 2濃度變化的影響因子溫度和水分中，溫度的影響作用高於水分；土壤剖面co _ 2濃度隨著深度增加，總的變化趨勢是遞增的，但也有反復，甚至有的順剖面而下幾乎保持一恆值，這與季節變化和黃土自身結構的通透性以及在觀測期內的乾旱氣候等條件有關。
