Soils dominated by 2:1 clays(montmorillonite, vermiculite, illite), more frequently found in temperate zones, but also present in tropical and subtropical areas; behave different from the typical tropical red soils (Ultisols and Oxisols dominated by Fe and Al oxides and kaolinite) and from the soils developed from volcanic ash (Andisols dominated by allophane, imogolite, and humus-Al complexes) that are widely spread over the world.
我们常在温带地区发现的2:1型粘土矿物为主的土壤,也出现在热带和亚热带地区。这些土壤不同于世界范围内广泛分布的典型的热带红壤(以铁铝氧化物和高岭石为优势粘土矿物的老成土和氧化土),也不同于由火山灰(以水铝萤石、伊利缟石和腐殖质-Al复合体为优势粘土矿物的火山灰土)发育的土壤。

There were different contamination conditions for different PAHs components in soils. Soils in urban area were severer contaminated by the height-weight-molecule PAHs than soils in agriculture area. However, there were the similar contamination level among different usages soils for the light-weight-molecule PAHs, such as naphthalene and methylnaphthalene.
不同种类的PAHs对不同利用类型土壤的污染情况也不相同,分子量较大的多环芳烃与总PAHs污染情况相似,表现为城市用地的污染程度要明显高于其它类型土壤;但分子量较小的组分,如萘和甲基萘,在不同利用类型土壤中污染程度相近。

It is obviously that the content of water of soils could influence the growth of plant and the physical character of soils. With the planting salt-enduring plants, mucosity of soils getting more reduced and porosity of soils getting more improved.
种植耐盐植物后的土壤中的含水量有明显提高,这主要是由于耐盐植物植入后,土壤的物理性质发生了相应的改变,土壤中粘粒减少,土壤孔隙状况比较好,使水分有较高的入渗率,这也是水分在改良后的土壤中积聚起来的一个原因。

Alpine steppe soilswhich is distributed from Tibet southeast to central section and northwestward is high cost ozone of soils base, CaO is primary in base matter, but KO is the second; the interbedded variety of Calcium and Magnesium is relative great in soils profile, especially Alpine desert soils in Tibet northwestward, base gross is the most, but interbedded variety in soils profile is decreased by a long way.
由此至中部和西北部的高山草原型土壤分布的盐基高值区,盐基物质以CaO占优势,而K_2O则退居第二位,土壤剖面钙、镁的层间变化相对较大;尤其位于西北角的高山漠土,盐基总量达到最高值,但其剖面的盐基层间变化却大幅度减小。

Based on soil radon gas survey in Quanzhou City and Jinjiang City, the authors conducted an investigation of the soil radon gas environment in an area of some 465 km2. The results indicate that radon gas concentrations in soils of Quanzhou and Jinjiang urban areas are at a lower level, whereas those in soils of Quanzhou and Jinjiang suburbs are at a fairly high level. It seems that the radon gas concentration is mainly related to geological background: radon gas concentrations in soils derived from weathering of adamellite, moyite, and biotite schist are higher than those in soils derived from weathering of other rock types.
通过泉州市、晋江市土壤中氡气测量,取得约465 km2土壤氡气环境调查成果,从结果来看,泉州市区和晋江市区土壤中氡气浓度普遍较低;市郊主要为山地,土壤中氡气浓度普遍较高;从土壤中氡气浓度水平的分布来看,土壤中氡气浓度水平主要与地质背景有关,二长花岗岩、钾长花岗岩、钾长浅粒岩及黑云片岩风化土壤中氡气浓度明显高于其他地质背景来源土壤。
