影响裂缝发育的主要因素是构造、物理风化和化学淋溶作用。 - The lateral or downward movement of dissolved or suspended material within soil when rainfall exceeds evaporation
淋溶作用当降雨量超过蒸发量时，土壤中溶解或悬浮物的向侧面或向下的运动 - The space produced by the crystallization is the second . the pores and the fractures , which have been remade by the chemical dissolution , are more favourable for the oil and the gas to store up
变质岩储集空间以构造和物理风化成因的裂缝为主，结晶成因的储集空间次之，这些孔、缝经过化学淋溶作用不同程度的改造，更有利于油气的储集。 - The main results are following : ( 1 ) the variation of clay / silt ratio can indicate the secondary clay action of dust depositions ; the variations of magnetic susceptibility and total fe content are inferred to be records of the changeable intensity of bio - pedogenesis ; the variations of sr content and rb / sr ratio can indicate bio - pedogenesis , dissolving and leaching action ; the content of total organic carbon ( toc ) can reflect variation of climate and vegetation during soil formation , it indicates the intensity of weathering and bio - pedogenesis ; the content variation of caco3 can show the intensity of dissolving - leaching action and secondary deposit , which was noted as pseudomycilia in pores and fissures in the sediment , so it can indicate the intensity bio - pedogenesis quite well . these proxy indexes also reflect obvious regional difference of pedogenic environment and the intensity bio - pedogenesis ; namely , secondary clay action , dissolving - leaching action and bio - pedogenesis are all much stronger in south than that in north
实验结果表明：粘粒粉沙比值能很好地指示粉尘堆积物的次生粘化作用；磁化率和全铁很好地指示生物风化成壤作用； sr和rb sr比值能很好的指示生物风化成壤作用和淋溶作用；总有机碳( toc )含量的高低，在一定程度上反应了土壤发育过程中气候和植被状况的变化，指示着成壤过程中腐殖质化的程度； caco3含量的变化，可以反映了黄土古土壤形成时的风化成壤作用的强弱程度，指示成壤过程中的淋溶作用和次生碳酸盐化作用；并且各指标所指示的成壤环境和成壤强度存在明显的区域差异，即渭河流域土壤的生物风化成壤作用、次生粘化作用和淋溶作用均表现出南部强于北部。 - The results indicate that : 1 . the main physical and chemical characteristics vary regularly : with rising of the altitude , there is a transition from silt > sand > clay to sand > silt > clay in the mechanical composition ; the argic horizon emerges below the altitude of 1600 meters ; the content of organic matter is enrichment , the content of organic carbon of epipedon is higher than 20 g / kg , while the content of organic carbon increases with increasing of altitude , and in the altitude of 3500 - 3700meters , the soils under the meadow have the maximum content organic carbon ; the soils appear acid - slightly acid reaction , the ph decreases appreciably and acid strengthen with increasing of altitude ; the soils higher than the altitude of 2500 meters are base unsaturated , indicating the soil leaching is strong , the ph and bs are distinct plus correlated ; the contents of sio2 , al2o3 , and fe2o3 of the soil body and clay are all relatively stabilization ; in the soil body , the content of sio2 is much high and cao is very little , the total contents of sio2 , a12o3 and fe2o3 occupy 92 % of the mineral parts , the sequence of mineral elements is : sio2 > al2o3 > fe2o3 > k2o > mgo > cao > tio2 > mno
研究结果表明： 1太白山南坡土壤的主要理化性质随海拔高度的上升呈有规律的变化：随海拔高度上升，机械组成由粉粒砂粒粘粒逐渐过渡到砂粒粉粒粘粒，海拔1600m以下出现粘化层；土壤有机质丰富，表层有机碳含量一般在20g kg以上，有机碳含量随海拔高度升高而相应增加，海拔3500 3700m的灌丛草甸植被下有机碳含量最高；土壤呈酸性或微酸性，并随海拔上升， ph值略微降低，酸性增强，海拔2700m以上的土壤多呈盐基不饱和状态，表明土壤淋溶作用较强， ph值和盐基饱和度呈极显著正相关；土体与粘粒中的sio _ 2 、 al _ 2o _ 3 、 fe _ 2o _ 3含量相对比较稳定，土体中sio _ 2含量较高， cao含量较少， sio _ 2 、 al _ 2o _ 3和fe _ 2o _ 3含量之和约占土壤矿质部分的92 ，矿质元素含量的顺序依次为： sio _ 2 al _ 2o _ 3 fe _ 2o _ 3 k _ 2o mgo cao tio _ 2 mno 。
百科释义
淋溶作用是指土壤内的水向下流动，使土壤上层部分（表土）的可溶性物质（矿物质、有机物）随着水分流失（至底土）的作用。为土壤形成的作用，成土作用的第一步。
