Loess loess [] refers to the dry weather conditions with the formation of a porous columnar jointed yellow silt, loess will have a greater subsidence by the water soaked. Quaternary continental formed earthy yellow silty sediments. Loess particle size from> 0.005 mm ~ <0.05 mm, the percentage composition of the particle size varies in different regions and different times. It is widely distributed in the northern mid-latitudes in arid and semi-arid regions. The mineral composition of loess have detrital minerals, clay minerals and authigenic minerals in Class 3. Detrital minerals are quartz, feldspar and mica, accounting for 80% of the detrital minerals, followed by a pyroxene, hornblende, epidote, chlorite, magnetite, etc.; addition, loess carbonate mineral content Multiple mainly calcite. Clay minerals are illite, smectite, kaolinite, goethite, hematite water. The chemical composition of loess in sio2 dominant, followed al2o3, cao, again fe2o3, mgo, k2o, na2o, feo, Τio2 and mno so on. The physical properties of loess showed loose, porous, vertical joint development, highly water seepage, and there is a lot of soluble substances, it is easy to form water erosion valley, also cause subsidence and collapse. Loess not tight binding between the particles, the porosity of 40% to 50%. Loess is the native loess, which is mainly homogeneous soil formed by the action of the wind; loess deposition refers to the transformation of the secondary flow through the loess. China North earthy late Cenozoic sediments in common with ancient soil distribution, especially in the loess plateau is most common. In the lower part of the loess paleosol layers of white calcium deposition is often manifested in the form of tuberculosis. Shaped nodules are elongated, irregular dendritic and spherical, are generally 15 to 25 cm long, 5 to 10 cm wide. Loess every continent in the northern hemisphere are distributed to most typical loess in northern China, in the middle reaches of the Yellow River constitute the famous Loess Plateau. Chinese loess distribution between latitude 34 ° ~ 45 °, was something to the zonal distribution, located in the northern mid-latitude desert - loess belt southeast. Loess is also broadly consistent with the trend towards the mountains and stuff, extensive loess north of the Kunlun Mountains, the Qinling Mountains, Titan line. China's total area is 380,840 square kilometers of loess, loess deposited a total area of 254,440 square kilometers. Loess area of the Yellow River which is 317,600 square kilometers. Loess thickness varies throughout Shaanxi Jinghe and Luohe River basin region, up to a maximum thickness of 180 to 200 meters. Chinese loess material mainly from the inland desert north latitude and east of the Caspian Basin region of 35 ° ~ 45 °. Desert basin updraft transported to the high altitude dust particles into the westerly circulation system, with high-altitude westerly flow from west to east, southeast drift to the east of longitude 100 ° area of large-scale _set_tlement. Piled up dust particles due to biochemical weathering occurs secondary carbonate to form loess. Loess is the quality of the soil. Not only does it have the humus layer of soil, leaching layer, three-tiered layer deposition characteristics, as well as other soil do not have unique qualities. Loess is a very fertile soil, agricultural production is extremely important. However, sparse vegetation, soil erosion, agricultural production and construction are causing serious harm, the need for scientific management. Loess is earthy dating Quaternary sediments formed about 200 million years. Typical loess is not gray or yellow brown powder dust and fine sand composition, texture, uniformity, containing large amounts of calcium or loess tuberculosis, porous, there is a significant vertical joints, no bedding, more rigid when dry, are water After soaking, usually easy to peel off and erosion, and even collapse occurred. Loess is mainly distributed in relatively dry continent in the world latitudes. The total area of the world distribution of loess about 13 million square kilometers. Distribution of China's loess, west of the eastern end of Gansu Qilian Mountains, east Shanxi, Henan, Hebei Taihang Mountains junction, south of the Qinling Mountains in Shaanxi, north to the Great Wall, including Shanxi, Shaanxi, Ningxia, Gansu, Qinghai and other five more than 220 cities and counties provinces, an area of 540,000 square kilometers, accounting for six percent of the country's land area. Loess Plateau in northwest China's Loess Plateau is the largest in the world, loess plains of North China is the world's largest loess plains.

Loess
Zouzhi An My father was a very ordinary peasants, working life, die quietly, like a loess. Loess long crops, but not too many people pay attention to. Most farmers are older so the whole China. He died of pulmonary heart disease. This is a serious threat to the health of working people disease. Chinese farmers in peacetime, is not very active body to the hospital, that is lying sick, but also drag mill. To eighteen years when my father was back in 馑 Nanshan food, go ice downpipe, back when frozen out of ten toenails, and tie down the root cause. After a half has been coughing sound, and never see a doctor medicine. Until a few months before his death, I was forced to go to the hospital were under the first ECG. Doctors analogy, said: "the machine running life, the host has to wear, so the lack of repair and maintenance of it!" To save, eat "Xinmaining" a class of more expensive drugs. He asked: "How much is a bottle?" Heard ternary, half silent, then said: "Do not buy medicine, I does not matter." When I am away, secretly stop taking their medication. He must be calculated: the value of a bottle of medicine to buy nearly two pounds of salt, let their wives work for several days. He also knows his life work. Heavy labor to make him tired knees. I do not know how much wealth creation, then he could not bear spending a penny. I once gave him two yuan pocket money let him buy delicious, six months after his body was still filled. During his illness appeared delirium, net mantra "do not feed the pigs," "hoes well", "yellow wheat closing soon" and the like. When he died quietly shed tears of nostalgia in this world - to make him sweat, but still not worth throwing affluent world. No father is nothing more than ever, care and could not understand a variety of national issues, can be said to be poor in spirit. Be given the rich, the poor are deprived, then he was deprived: the former because of poverty and lack of access to education, and later touches continue to accept all kinds of political education, but finally did not understand. But he apparently did not regret it, because he has work, thus fills all defects. Coincidentally wise men who labor concerns, incompetence want nothing ...... but he still asked for - pray things do not mess with stable life. He is now gone! Loess labor life, and finally back to the loess go. Loess is a broad tolerance, regardless of good and evil, eventually accommodated all. I was kneeling in the mud to see him off. I once thought: He lived aged 77, has been very difficult; while we can live around seven or eight years old and too small. Not old people want to live, no means no filial sons and daughters, it is bad because the standard of living. So, as soon as possible to develop production and improve people's lives, it is the children who retain many elderly people in the moment the best way of filial piety. Cry in vain, sadness but also helpless. Dead long gone, the living when struggling to. Generals and leaders of the dead, there will be countless condolence because they feats impeccable. An ordinary laborer died, we planted this the loess, and expect the world to accommodate.

huangtu Loess loess The main special yellow Quaternary sediments. Loess color yellow, shades of difference in hue; uniform particle size distribution, particle content of the powder composition of soil particles _set_ up more than 50 to 60%, and in coarse soil particles group (0.05 to 0.01 mm) dominated; contains a lot of carbon acid, the content is generally more than 6 to 8%. Loess may also have other characteristics. Such as non-rational level, with large pores and space, containing the remains of plant roots, with a vertical cleavage, as well as collapsible water and so on. According to the special needs of some of the salient features of loess or research and development, but also divided into sandy loess, clay loess, loess, non-loess, large pores loess, loess new and old loess, eolian loess, alluvial - loess slope deposits. Loess and clay and sand content of rare, rare particles larger than 0.25 mm. Loess minerals dominated by quartz, clay minerals are illite, kaolinite and montmorillonite containing a small amount. Collapsible loess loess refers to the weight or by immersion in the role of additional load produced a sudden sinking of nature (Figure 1 loess deformation after flooding (collapsible)). Collapsible construction often to harm (Figure 2 due to the collapsibility damage resulting from irrigation channels along the diagram). Said collapsible when pressure is applied by the weight and collapsible, otherwise known as non-collapsible. So that non-collapsible collapsible soil emergence minimum pressure, said collapsible initial pressure after flooding. When collapsible collapsible relative coefficient □ sh evaluation, □ sh ≥ 0.02 as loess, □ sh predict dry density as a basic indicator of collapsible loess, such as dry density of less than 1.28 g / cc, after flooding generally produce collapsible; dry density greater than 1.40 g / cc collapsible when it is weak. Thus, the dry density greater than 1.40 g / cc as a stable water loess boundary indicator. The reasons for the geological origin of loess loess, academia has been debated for nearly a century. Since the 19th century, eolian origin hypothesis has been dominant. To the 1950s, some scholars have put forward different views. Some believe that the role of the alluvial river about; some that are alluvial causes; was also suggested that the role is the result of making soil. Although these ideas put forward some of their basis, but failed to make in-depth demonstration system, which failed to arouse widespread attention. With magnetic and thermal luminescence measured Chinese Loess Plateau and other methods have begun to accumulate in about 240 million years ago. Some scientists believe that China Chinese loess by a variety of geological forces role in the accumulation and under similar climatic conditions, the effect after the formation of loess. Process and the formation and development of loess accumulation of loess material summed to form a special bond structure of loess, loess restructuring and strength increase, as well as four stages of loess degradation. Loess loess covered around 11% of the global land surface, concentrated in temperate and semi-arid areas with the leading edge of the desert. Chinese loess distribution area of 44 million square kilometers, especially in the middle reaches of the Yellow River, 100 to 200 m thick loess continuous covering an area of about 273,000 square kilometers, forming the world's rare Loess Plateau.
