土壤发生

Scientist: The point is that the worlds soils are a very large reservoir of carbon and two things can happen you can either manage it so they get bigger and therefore lock up carbon, or mismanage it so that pore gets smaller and in fact you release carbon and add to the CO2 in the atmosphere and it works both ways.

科学家：我们要指出的是，地球上的土壤是一个巨大的碳储存库，有两种情况会发生，一方面我们正确的利用它，增加它的容量以达到固碳减排的目的，另一方面我们的错误做法会使土壤中气孔变小，造成碳释放，增加大气中的二氧化碳含量，事实上这两种情况是同时存在的。

Along with the variety of altitude, the mountainous climate、vegetation、biology、parent population etc also have regular varieties, So the mountain soils represent distinct vertical variations on the vertical zone, and that engender many type of soils.

垂直地带是山地所特有的自然现象，随着海拔高度的变化，山地气候、植被、生物、成土母质等自然要素也发生着规律性变化，因此，山地土壤在垂直带上表现出明显的分异规律，形成多种土壤类型。

The principal character of soil erosion in Ninxia is grave soil and water loss in central and southern area, and strong wind erosion in the northern area.

After orthogonal test analysis of three factors, three levels and 27 kinds of compositions,the causes of the putridity of the Rugosa rose fresh cuttings were investigated.

通过三因素三水平 2 7种组合的正交试验和分析，认为插穗腐烂病的发生是由于难生根的离体保加利亚玫瑰嫩枝插穗的抗性弱、空气和土壤的高温高湿条件所造成的；分析还表明土壤因素对保加利亚玫瑰嫩枝扦插腐烂病影响最大，其次是插穗因素和浸穗试剂，并据此提出感病率较低的 4种组合类型。

Has weak activation and transfer under acid rain effect and redeposition will take place during the course of their moving from surface soil to deep soil. Contrasted quality standard analysis of surface water, ground water and drinking water, these elements will not bring about negative effect to the water environment and ecological environment of soil.

进一步相态分析结果表明，受酸雨淋滤作用的影响，离子的迁移主要发生在盐基离子上，具体表现在经酸雨淋滤后表层土壤水溶态组分中盐基离子浓度降低，与此相对应的是Al离子浓度显著增高，一个直观的反映是土壤的电导率降低。

The total microbial numbers in fixed sand were 2.8 and 12.5 times as many as those in semi-fixed sand and in sand-flowing dune,respectively.

土壤微生物，在风沙土的发生、土壤肥力的形成和发展、营养元素的转化中起着不可替代的作用[1]。

In the paper, we mostly studied the change of soil erosion process by a new REE tracer method, based on the theories of hydraulic mechanical subject and radionuclear tracer method, and simulated rainfall was applied to study the sheet erosion changing to rill erosion and the rill erosion process on slope land. The new REE tracer method should be useful to future studying of erosion processes on slope lands.1. Offering and testifying a new REE displacing method to study on the soil erosion of the loess slope.

本文以黄土坡面土壤侵蚀形态演变规律为研究重点，以新的核素示踪技术为手段，采用水动力学与核素示踪技术相结合、室内人工模拟降雨与稳定性REE元素示踪相结合的方法，利用先进的INAA技术，定量研究了不同雨强次降雨条件下细沟间侵蚀向细沟侵蚀的转变过程、细沟发生发育过程，为深入了解坡面侵蚀过程，建立黄土高原土壤侵蚀预报模型提供了研究基础。

The results showed that vegetation coverage and biomass of enclosed desert grassland increased by 272%～536% and 44\^39%～305\^5% respectively compared to those of unenclosed desert grassland under the similar environments.

植被的恢复使土壤理化性质发生了变化，与封育前相比土壤中有机质、全N、速效K以及细砂、特别细砂和粘粒含量显著增加；速效N、速效P降低。

In fact, soil salinization and alkalization frequently co-occur, and this has caused severe problems in some areas, such as in northeast China.

对于内陆盐碱地来说，特别是中国东北盐碱化地区，其土壤盐化和碱化往往交织在一起相伴发生，所以，盐碱混合胁迫才是该地区土壤危及植物的主要问题。

Arbuscular mycorrhizal fungi are important soil microorganisms in agroecosystems. Biodiversity among AM fungi in crop fields is influenced by many factors, including soil properties and plant species.
