3 ) the soil moisture under the artificial community was twice that of non - vegetation slopes ; topsoil moisture increased by more that 200 % during the rainy season , but in the dry season the soil moisture under the introduced vegetation was close to or even lower than that of non - vegetation slopes ： 3 )根據土壤含水量的分析，雨季植被下土壤含水量比光坡地增加約100 ，表層上則增加2倍以上；但旱季，喬木林地土壤含水量與無植被覆蓋地相近甚至低于無植被覆蓋地。
In the zinc deficient cumulic cinnamon soil of northern china often encountered by dry climate , although the storing water in lower soil depth could not promote early maize plant to take up more zn from soils , our research gave a clear point that soil water in upper soil layer was important to enhance the influence of zn application in topsoil on early maize growth 表層土壤水分對苗期玉米植株鋅吸收總量有顯著影響，干旱條件下，玉米植株鋅吸收總量下降；底層土壤水分供應狀況對玉米鋅濃度影響不大，但植株中鋅向地上部運轉增加。
Experiments of artificial rainfall showed that sediment is the main body of total nutrient loss and runoff is the main body of available nutrient loss when erosion is slight , but sediment become the main body of total and available nutrient synchronously while erosion is intense . concentration of nutrient in runoff is most likely to be affected by concentration in topsoil . the higher concentration in topsoil is , the more possible nutrient loss by runoff is 人工降雨實驗結果表明，在降雨強度和侵蝕強度不大時，侵蝕泥沙是全量養分流失的主體，地表徑流則是速效養分流失的主體；而當在降雨強度和侵蝕強度極為劇烈時，侵蝕泥沙成為全量養分和速效養分二者流失的主要載體；地表徑流中的養分含量很大程度上受土壤中養分含量的影響，土壤中養分含量越高，養分徑流流失的可能性越大。
The project was carried out to study the changes of topsoil surface structure and the relationship between soil surface structural change and the soil erosion under simulated rainfall , by measuring erosion parameter and observing soil surface micro morphology during the process of rainfall 本實驗以鄂南幾個侵蝕紅壤為研究對象，運用人工模擬降雨方法，通過測量侵蝕參數與觀測不同時段的表土微形態，力求找出降雨過程中紅壤表土結構的變化過程及其與土壤侵蝕的關系，為我國南方水土流失提供理論依據。
2 . the range of soil co2 concentration varied with soil temperature is not the same for the soil layer and its characters and different vegetation : the varied range of topsoil is higher than that of deep soil at testing woodland ; the varied range of soil layer ( - 20cm ) is the highest than that of the other soil layers ; the range of co2 concentration varied with air temperature begins to increase in turn from woodslay and shrublay to herbage 由于植被覆蓋類型不一樣和所處的層位以及本身性質，表層帶巖溶生態系統各層的coz濃度隨溫度變化的幅度不一樣，林地表層coz濃度變化的幅度比深部大，裸地土下e0 。 zcoz濃度變化的幅度比表層和底層大，林層、灌層和草層coz濃度變化的幅度依次變小。
Over - grazing and irrigation methods that wash away topsoil were to blame for some of the damage , experts said . building developments and climate change were doing the rest . spain builds an estimated 180 , 000 holiday homes along its coast every year 西班牙有報紙6月17日評論說： “如果任由事態發展下去，我們以后就不需要專門跑到北非去欣賞沙漠所特有的靜寂氛圍了，只要到加那利群島巴倫西亞或穆爾西亞走一趟就可以了。 ”
The wonderful loess lands , which cover much of kansu , shensi , ninghsia , and shansi provinces , account for the marvelous fertility of these regions ( when there is rainfall ) , for the loess furnishes an inexhaustible porous topsoil tens of feet deep 這一令人驚嘆的黃土地帶，廣及甘肅、陜西、寧夏、山西四省的大部分地區，雨量充分的時候異常肥沃，因為這種黃土提供了無窮無盡的、有幾十英尺深的多孔表土層。
Change rules of soil p and k were complex , and their content was mainly related to parent material . from soil biological properties analysis , soil bacteria , fungi , actinomycetes and total of microbes in the topsoil were higher than in the bottom layer 各林地土壤腐殖質、胡敏酸和富里酸含量表層大于底層，在土壤腐殖質組成中， fa含量大于ha ，由于富里酸移動性較胡敏酸強， ha fa表層大于底層。
Article 32 the local people ' s governments at and above the county level may demand units which occupy cultivated land to use the topsoil of the land occupied for use in the newly reclaimed land , poor land or other cultivated land for soil amelioration 第三十二條縣級以上地方人民政府可以要求占用耕地的單位將所占用耕地耕作層的土壤用于新開墾耕地、劣質地或者其他耕地的土壤改良。
Otherwise , how will i know if my method works or not ? incredibly , just after he finished cultivating his land , rain came to his area . it was not very heavy , but the water managed to penetrate the topsoil , and held together the dry surface soil and the wet soil beneath 奇怪的是，他剛種完地就來了一場雨，雨雖然不大，但滲透地面之后，總算把表層的乾土和地下的濕土結合在一起了。
Thisrough terrain , with its mainly granitic ground that is susceptible to the lossof topsoil nutrients , created acute challenges for reforestation , which only could be overcome with much hard work , dedicated effort and wise planning 因此，必須以加倍的努力和熱誠，以及明智的規劃，方能排除萬難，重植綠蔭。事實上，不論在香港每一角落，重新植林的任務俱艱巨無比。
Tokyo gas , the utility whose land it was , is removing 2m ( 6 . 6 feet ) of topsoil , and 2 . 5m of fresh soil is going on top , but environmentalists say that an earthquake or a tidal surge would bring the benzene straight back up to the surface again 東京燃氣因此將深達兩米（ 6 . 6英尺）土壤表面挖掉，填回了2 . 5米的新土，但是環保人士稱地震或潮汐仍將把苯毒再次翻上來。
Factors which influence field soil water infiltration characteristics have soil structure , soil moisture , soil texture , topsoil crusting and plate , agriculture husbandry measure and soil water phase change and so on 影響大田土壤水分入滲特性的因素有：土壤結構、土壤含水量、土壤質地、表土結皮和板結、農業耕作措施和土壤水的相變等。
Organic matter and available n of topsoil decreased in recreational areas , but the soil bulk density and ph increased . affected by garbage decomposing , soil available p concentration varied obviously in recreational areas 活動區土壤有機質含量降低， ph值升高，容重增大，堿解氮含量降低，受垃圾分解影響，速效磷含量發生變化。
Ground source heat pump ( gshp ) consumes a little electricity power and makes the best of the reproducible low temperature in the topsoil of the earth of crust to condition the indoor air 地源熱泵技術充分利用地殼表層土壤中的可再生低溫,通過消耗少量的電能,對室內進行供暖/制冷。其占地面積小,無任何污染,運行耗電少、成本低。
In most cases , extracting oil involves chopping down the forest that blankets the region , draining the boggy ground , stripping off the topsoil and literally digging up the oily sand below 在大多數情況下，要從油沙中提煉出石油需要先把覆蓋該地區的森林砍掉，排干地面的水分，去掉表層土然后當然就是把地下的油沙挖出來。
To overcome the problem of insufficient topsoil , they covered the ground with a layer of soil into which seeds were sown . but the wind that had been blowing in from tolo harbour for centuries swept everything away 表土不足，他們運來泥土，鋪在石地上，播種灌溉，但吐露港北風吹來，把樹苗泥土都一并帶走。
Over - grazing and irrigation methods that wash away topsoil were to blame for some of the damage , experts said . building developments and climate change were doing the rest 專家指出,因過度放牧或將表土層完全沖刷的灌溉方式都要對土地沙漠化負責.當然房屋開發和氣候變化也逃脫不了干系
Changes of soil nutrients occurred mainly in the topsoil . base on the results of this study , we advance ten models of pioneer community for the purpose of popularization 根據研究結果，即根據被測植物的生態適應特征及群落構成的原則提出9種適于推廣應用的先鋒植物群落模式。
