棄土場坡面地表土壤特性隨著降雨擊濺和徑流沖刷的作用而發(fā)生變化,從而影響區(qū)域內(nèi)徑流和滲流途經(jīng),造成坡面產(chǎn)流的不一致性。 - Results were as follows : surface erosion occurs in vast areas , but in low intensions ; gravitation erosion was caused by rainstorm , and always happened in steep slope with gradient degree more than 35 ; water loss is the most important form in low mountainous areas
結(jié)果表明:坡面面蝕發(fā)生范圍廣,程度重,但強(qiáng)度不大;重力侵蝕的誘因是暴雨,多發(fā)生在坡度大于35 %的陡坡坡面;水的流失是低山丘陵區(qū)坡面水土流失的重要形式。 - It's difficult to find surface erosion in a sentence. 用surface erosion造句挺難的
- The effect of splash erosion on sloping surface erosion is evident . after the splash erosion was eliminated , the erosion amount was less than half of the amount when the splash erosion existed . it indicated the splash erosion contributed more than 50 % erosion amount , but to the different soil type , the contribution ratio of erosion amount varied , such as the soils derived from granite , the contribution ratio reached 70 %
在有無紗網(wǎng)兩種處理?xiàng)l件下的產(chǎn)沙實(shí)驗(yàn)表明,雨滴濺蝕對坡面土壤侵蝕量有明顯的影響,消除濺蝕作用后土壤侵蝕量不到有濺蝕作用的一半,說明濺蝕對坡面產(chǎn)沙的貢獻(xiàn)占50以上,不同土壤類型其貢獻(xiàn)率不同,如結(jié)構(gòu)性較差花崗巖紅壤,濺蝕貢獻(xiàn)率高達(dá)70 。 - The research results mainly show : ( 1 ) the ecological degradation characteristics of wuxi county include : some soil is thin and barren and its water and fertility conservation abilities are poor , gradual degradation of soil results in decrease of vegetation diversity and the vegetation community structure gradually inclines tc simplicity from complexity . the types of soil and water loss in wuxi county mainly involve surface erosion and gully erosion . according to investigation , surface erosion area occupies 80 % or so or erosion area , in which the slope farmlands surface erosion area accounts for about 70 % of farmland erosion area
研究結(jié)果主要包括: ( 1 )巫溪縣生態(tài)退化特征表現(xiàn):作為生物生長基質(zhì)的部分土壤薄而貧瘠,保水保肥能力差,部分地區(qū)基巖裸露,土壤的不斷退化導(dǎo)致植物種多樣性減少,植物種群結(jié)構(gòu)逐步由復(fù)雜趨向簡單化;縣內(nèi)水土流失的類型主要包括面蝕和溝蝕兩大類,據(jù)調(diào)查,面蝕面積占侵蝕總面積的80左右,其中坡耕地面蝕占耕地侵蝕面積的70左右。
