一、岩石性質与风化作用及其产物土壤中的矿物貭部分,是岩石的风化产物,岩石的性貭不同,其风化产物必然也不相同,这就很自然的影响了它所形成的土壤的性状与肥力。这种情形,在地理环境相同的地区,表現得十分清楚。也正是因为这些,道庫恰耶夫(俄罗斯土壤学奠基人)才把岩石当作是影响土壤发生与发育 First, the nature and weathering of rock and its products Mineral part of the soil is the weathering of rock products, rocks of different temperament, its weathering products are not necessarily the same, which naturally affects the formation of the soil Traits and fertility.
