黃土丘陵區植被恢復過程中土壤酶活性的響應與演變In the light of its special property being not easy to gain strength, through mechanics researches on different methods to stabilize this kind of low _ liquid _ limit silty soil as subbase material, evaluated both technically and economically, we have got a cement lime stabilization plan to meet the index requirements for non _ side _ limit strength of compression of subbase of class2 road stipulated in the specification ; by means of improving the workmanship, thickening the loose layer of soil, adding soil on covering weave fabric before compaction, such problems can be solved as very poor compaction, loose surface during compaction, roughness and unevenness, coats of layer and shear damages
本文針對黃河沖積而成的低液限粉土其粘粒含量極低、土的不均勻系數很小、膠體活性差的工程特性,通過採用不同方法穩定該類土作底基層材料的力學性能研究,從技術、經濟角度綜合評價,得到滿足規范抗壓強度指標要求的水泥石灰穩定方案。通過對原材料、試驗配合比設計、施工、等方面進行優化,從而顯著減輕了基層的早期及長期縮裂程度,從而提高了路面的耐久性。Soil enzyme activities in different plantations in lowlands of the yellow river delta, china

經過對這些資料的綜合系統分析,對黃河三角洲地區第四系地層沉積特徵、隱伏斷裂的位置及活動性、區域地震活動特性、深部地球物理場、構造應力場、地溫場特徵,地震地質災害特徵和地震砂土液化預測評價等做了較為深入的研究,對比分析了渤海強震區與黃河三角洲地震地質特徵的差異性,取得了具有重要意義的成果。On the discussion of feasible development of the holiday tour areas in the loess plateaus which is ecologically weak regions and by taking the example of shijiagou which is traditional upland yao - dong village in the ravine regions, the thesis aimed to scoop out local advantage travel resources and biology gene, and combine holiday tour areas development with green residence situation to conclude a feasible development model which has local special feature of holiday tour areas by persist in the sustainable biology traveling way and plan principle, viewing the ecological structure as whole and using modem green architectural technique and material. this model can not only satisfy the modern people ' s life request but also improve and make use of biology environment. what ' s more, it will promote the development of local economy, society and culture, and also realize organic combination of economy biology and society value
本文在論述黃土高原生態脆弱地區度假村可行性開發的基礎上,以溝壑地區傳統山地窯居聚落師家溝村為例,挖掘當地旅遊優勢資源條件和生態基因,堅持走可持續生態旅遊之路,並將度假村建設與綠色人居環境創建相結合,以整體建築生態觀和生態規劃原則為指導,利用現代綠色建築技術和材料,試圖總結出既能滿足現代人生活要求,又能利用和改善生態環境的具有地方特色的度假村可行性發展模式,從而促進地方經濟、社會、文化發展,實現經濟、生態和社會效益的有機結合。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。分享友人
