1、SoilSolutions of Soil Problems 吳澤1.;aftermath n.后果，結(jié)果 Human beings have causes soil problems as their history can be traced.But they havent realized its serious aftermath until recently. 追溯人類的歷史，人為造成的土壤問題早就存在了。但人們直到最近才意識到它的嚴重后果。2.; In order to protect or even improve soil quality,scientists try hard

2、 to deal with soil erosion and soil pollution. 為了保護甚至改善土壤質(zhì)量,科學家們努力的去處理土壤侵蝕和土壤的污染。3 Soil erosion is one of the most critical environmental and soil problems facing humanity today. 土壤侵蝕是今天人類面臨的最嚴峻的環(huán)境和土壤問題之一。4.; Erosion makes soil less productive of the plant on which animal and human depend,and being

3、disabled to sustain water and protect from drought. 侵蝕使土壤所產(chǎn)生的人類和動物所依賴的植物的產(chǎn)量有所降低,使之失去了保持水分和抗旱的能力。 5.; Equally important,erosion causes great damage in reservoirs,lakes,waterways,and municipal water supplies. 同樣嚴峻的是，侵蝕對水庫、湖泊、河道、和城市用水的供應(yīng)造成很大的損害。6.; Wind erosion also causes fugitive dust that may be ver

4、y harmful to human health. 風蝕造成的揚塵可能嚴重危害人類健康。 fugitive adj.無常的，易變的7.; Protecting soil from the ravages of water and wind is by far the most effective way to constrain erosion. There are two types of measures. They are engineering measures and ecological measures. 到目前為止，保護土壤不受水蝕風蝕破壞的最有效的方法是約束侵蝕。約束侵蝕有

5、兩類措施，即工程措施和生態(tài)措施。ravage n.破壞，創(chuàng)傷，蹂躪constrain vt.強迫，抑制，拘束8.; Engineering measures are using terraces,or some other buildings to sustain soil;ecological measures mainly use plants to sustain soil and improve soil quality. 工程方法是使用梯田或其它建筑物來保持土壤; 生態(tài)方法主要是運用植物來保持土壤和改善土壤質(zhì)量。terrace n.梯田，梯田的一層9.; In croplands a

6、nd forests，such protection is due mainly to the cover of plants and their residues. 在農(nóng)田和森林中，土壤保護主要是以植物覆蓋和他們的殘留來實現(xiàn)的。cropland n.農(nóng)田，植作物之農(nóng)地residue n.殘余，濾渣，剩余物10.; Maintaining coverage density at least 30% has contributed to the significant reductions in soil erosion. 維護至少30%的植被覆蓋率可以顯著的降低土壤侵蝕。 11.; For t

7、he sake of future forest productivity and current water quality, foresters must become more selective in their harvest practices and invest more in proper forest road constrain. 為了未來的森林生產(chǎn)力和流水的水質(zhì)，林業(yè)工作者應(yīng)該更加有選擇性地從事收獲活動，并且在森林道路數(shù)量的限制中投入更多的精力。12.; Constrain sites for buildings, road, and other engineering

8、 projects lay bare many scattered areas of soil that add up to serious soil erosion problems. 建筑物、道路和其他工程項目的限建場地裸露的分散在各個區(qū)域，加重了土壤侵蝕的問題。 13.; Control of sediment from constrain sites requires carefully phase land clearing, along with vegetative and artificial soil covers, and installation of various b

9、arriers and sediment-holding ponds. 控制限制場地的沉積物需要階段性的仔細的進行地面清掃，同時還需要植被和人造的土壤覆蓋，以及各種屏障和沉積物貯存池。 phase v.按計劃進行，使配合14.; Soil erosion-control systems must be developed in relation to those use the land, and especially the poor, for whom immediate needs must overshadow concerns for the future. 土壤侵蝕控制系統(tǒng)必須建立

10、和土地使用者的關(guān)系，特別是窮人，對他們來說，眼前的需要遠大于對未來的擔憂。 overshadow v.遮蔽，使失色15.; People always cause pollution, but significant concern about pollution problems is a recent development as a result of increasing population, new types of pollutants, and increasingly sensitive techniques for detecting pollutants. 人們總是造成污

11、染，但對污染問題的高度關(guān)注是隨著近年來人口的增長、新型污染物的產(chǎn)生和越來越敏感的污染物檢測技術(shù) 。 16.; In order to protect soil and improve soil quality, we must do soil environmental quality assessment to comprehend and grasp the capacity and quality of soil. 為了保護土壤和改善土壤質(zhì)量,我們必須對土壤環(huán)境作出評估來理解和把握土壤能力和特性。 assessment n.評估，評價估計數(shù)17.; Soil pollution is t

12、he key segment of environmental pollution. Most pollutants and the products of their breakdown in soil reactions can be toxic to humans and other animals if the contaminants move from the soil into plants, soil fauna,and particularly into water supplies. 土壤污染是環(huán)境污染的關(guān)鍵部分。如果大量的污染物和它們在土壤中分解的產(chǎn)物從土壤中進入植物、土

13、棲動物，尤其是進入水源，將對人類和其他動物是有毒性的。 fauna n.動物群，動物區(qū)系18.; Protecting soil from pollutions is to control the sources of pollutants and reduce the quantily of pollutants in soil. 保護土壤不受污染，主要是控制污染源和減少土壤中污染物的數(shù)量。 19.; According to the environment-protection policy in our country, dealing with soil pollution must

14、give first place to prevention. 根據(jù)我國環(huán)保政策, 應(yīng)對土壤污染必須以預(yù)防為主。 20.; That is to say, in order to protect soil from pollution, the main measure we can take is to control and remove the sources of pollutants. 也就是說：為了保護土壤不受污染，我們可以采取的主要措施是控制和消除污染物的來源。 21.; Therere some measures to control pollution sources, su

15、ch as reducing the use of pesticides, using fertilizers, controlling the quantity of industrial waste-water and sewage water, etc. 還有一些控制污染來源的措施,比如減少使用殺蟲劑和肥料，控制工業(yè)廢水和污水的排放等措施。 22.; The main methods to improve the quality of polluted soil are physical measure, ecological measure and chemical measure,

16、for instance, deep tillage, organism absorption,using inhibitor and organic fertilizers and so on. 改善受污染土壤質(zhì)量的主要方法是物理措施、生態(tài)措施和化學措施，例如，深耕作、生物吸收、使用抑制劑和有機肥料等。. inhibitor n.抑制劑，抑制者23.; Soil and water conservation deals with the wise use of these important resources. Wise use requires understanding, knowle
