| 2. | This distribution pattern of soil carbon was related to such factors as the precipitation eluviation and the organism activities in soils
土壤碳的这种分布格局与大气降水的淋溶、土壤生物活动等因素有关。 |
| 3. | 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
土壤碳酸钙( caco _ 3 )的淋溶淀积过程是黄土高原以及干旱和半干旱地区土壤形成发育的主要过程之一，也是地球化学过程的主要内容。 |
| 4. | Results indicated that rain eluviation was one of the means by which p . multisectum released allelochemicals , the allelopathy of the leaching might play an important role in enhancing the competitive ability of the species
由此表明，雨水淋溶是多裂骆驼蓬向环境释放化感物质的途径之一，化感作用在增强其生态竞争力和扩大种群中起着重要的作用。 |
| 5. | 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
土壤碳酸钙淋溶淀积是一个复杂的过程，土壤中的co _ 2通过控制土壤ph值和碳酸钙的溶解性来影响土壤碳酸钙的淀积，是重要的影响因子之一。 |
| 6. | The distribution and change pattern of soil co2 concentration in soil profile data are analyzed as well as its effect factors . a model for soil caco3 eluviation - illuviation is developed based on mechanism of soil chemical thermodynamic principle and applying other modeling experience for reference
本文以砖窑沟流域为例研究和分析了土壤剖面co _ 2浓度的分布变化规律及其影响因子；对土壤碳酸钙淋溶锭积进行了定性、定量研究。 |
| 7. | The intense eluviation and weathering of soil with groundwater and run - off result in the enhancing of capacity of transference of some elements , such as si , al , fe , mn . the chemical reactions of the colloid particles in the soil water make those crannies or holes filled by some epigenetic clay minerals and quartz . then a great deal of white reticulate clay comes into being in the quaternary laterite of the dongting basin
地下水和地表水强烈的淋溶作用使土壤中硅铝铁锰等元素的迁移能力增强，土壤胶体粒子之间的化学反应，使得这些孔隙空间在后期逐渐被次生黏土矿物和石英所充填，最终，在洞庭盆地第四系红土地层中形成大量的蠕虫状和根状白色网纹。 |
