淀積土壤 的英文怎麼說
中文拼音 [diànjītǔrǎng]
淀積土壤
英文
illuvial soil-
( 3 ) the spatial analysis results showed that the variation of soil clay content was moderate at the direction of vertical section. the soil clay content was highest at the layer of 20 - 40cm, which showed that it is an eluvial accumulation horizon according to long - term cultivation, irrigation and rainfall
（ 3 ）土壤粘粒含量在垂直方向上呈中等變異，整個土體在20 - 40cm土層處的粘粒含量最高，說明土壤表層由於長期耕作、灌溉降雨，土壤粘粒含量有一個淋溶淀積過程。Soil caco3 eluviation and deposition process is the most important development and evolution process of soil, from parent material to mature soil in the loess plateau, arid and semiarid area
土壤碳酸鈣（ caco _ 3 ）的淋溶淀積過程是黃土高原以及乾旱和半乾旱地區土壤形成發育的主要過程之一，也是地球化學過程的主要內容。Soil caco3 eluviation - illuviation is a relatively complicate process, soil co2 is one of the important effect factors, which influences soil caco3 through controlling soil ph value and caco3 solution capability
土壤碳酸鈣淋溶淀積是一個復雜的過程，土壤中的co _ 2通過控制土壤ph值和碳酸鈣的溶解性來影響土壤碳酸鈣的淀積，是重要的影響因子之一。Caco3 not only affects soil physical and chemical characteristics but also causes co2 change in the air, because caco3 is main components among the total pool of inorganic carbon of soil. this paper systematically summarized and analyzed general development characteristics of soil profile caco3 in loess hill gully area including source, content, forming - condition, distribution and illuviation - depth of caco3, which will have the most important significance for the further studies on global soil and climate change
碳酸鈣在土壤剖面中淀積的深度和類型是黃土高原土壤發育的重要標志，鈣積層是黃土高原土壤發育環境的歷史信息庫，同時土壤碳酸鈣作為土壤無機碳庫重要組成，它通過溶蝕后再結晶與大氣co _ 2之間進行物質交流來影響全球氣候變化。The model should be coupled with other model such as random rainfall model, evapotraspiration model etc, and avoid subject factor effect. the aim is to evince accurately general law of caco3 deposition, provide scientific basis for making strategic decisions on soil management and environment protection
同時，所建模型有待于結合影響caco _ 3淀積綜合因素的其他因素模型如隨機降水模型、蒸散模型等（ marion等， 1985 ）建立耦合系統模型並加以改進完善，避免主觀因素影響，使其能準確地反映caco _ 3淀積的一般規律，指導土壤管理和環境保護。There are higher potassium and calcium carbonate content, larger ph, lower organic matter, nitrogen and phosphoric. compared sandy soil with zonal soil, mechanical composition is coarsal, there are no substance leaching. 3
土壤鉀素、碳酸鈣和ph值較高，有機質和氮、磷養分貧乏，風沙土與地帶性土壤相比，機械組成明顯粗化，物質未發生淋溶淀積。分享友人
