【摘要】：為了研究湖南省東部花崗巖紅壤在中國(guó)土壤系統(tǒng)分類中的歸屬,選取湘東地區(qū)8個(gè)由花崗巖母質(zhì)發(fā)育的典型土壤剖面,在對(duì)其成土環(huán)境、剖面形態(tài)特征及其理化性質(zhì)進(jìn)行研究的基礎(chǔ)上,按照中國(guó)土壤系統(tǒng)分類方案,檢索出了其診斷層和診斷特性,據(jù)此確定了其在中國(guó)系統(tǒng)分類中的歸屬。結(jié)果表明,供試的8個(gè)土壤剖面包含了淡薄表層、暗瘠表層、低活性富鐵層、黏化層等9個(gè)診斷層和診斷特性,其在中國(guó)系統(tǒng)分類體系中的位置分別為:淋溶土、富鐵土和雛形土3個(gè)土綱;濕潤(rùn)淋溶土、濕潤(rùn)富鐵土和濕潤(rùn)雛形土3個(gè)亞綱;簡(jiǎn)育濕潤(rùn)富鐵土、鋁質(zhì)濕潤(rùn)淋溶土、酸性濕潤(rùn)淋溶土和鋁質(zhì)濕潤(rùn)雛形土4個(gè)土類;普通鋁質(zhì)濕潤(rùn)雛形土、普通簡(jiǎn)育濕潤(rùn)富鐵土、普通鋁質(zhì)濕潤(rùn)淋溶土、普通酸性濕潤(rùn)淋溶土4個(gè)亞類;按照土族和土系劃分標(biāo)準(zhǔn),建立了黏壤質(zhì)硅質(zhì)混合型酸性熱性-普通鋁質(zhì)濕潤(rùn)雛形土等6個(gè)土族和脫甲系(43-CS18)等8個(gè)土系。實(shí)踐表明,目前的土族土系劃分標(biāo)準(zhǔn)適用于供試土壤基層分類單元?jiǎng)澐�。與土壤發(fā)生學(xué)分類結(jié)果相比,土壤系統(tǒng)分類結(jié)果更能定量反映出湘東花崗巖母質(zhì)發(fā)育土壤性狀的差異,進(jìn)而客觀反映出土壤發(fā)育階段和土壤類型的差異。
[Abstract]:In order to study the classification of granite red soil in eastern Hunan Province in China, eight typical soil profiles developed by granite parent material in eastern Hunan were selected. Based on the study of the morphological characteristics and physical and chemical properties of the section, according to the systematic classification scheme of soil in China, the diagnostic faults and diagnostic characteristics were searched, and the classification of the profile in the systematic classification of China was determined. The results showed that the eight soil profiles included nine diagnostic faults and diagnostic characteristics, such as thin surface layer, dark barren surface layer, low active iron rich layer and viscous layer, and their positions in the systematic classification system of China were as follows: leached soil, There are three soil classes: iron-rich soil and rudimentary soil. There are three subclasses of moist leachate soil, moist iron-rich soil and moist rudimentary soil, and there are four kinds of soil: moist iron-rich soil, aluminum moist leached soil, acidic moist leached soil and aluminum moist rudimentary soil. There are four subtypes of common aluminum moist rudimentary soil, ordinary simple nourished moist iron-rich soil, ordinary aluminum moist leached soil and common acidic moist leached soil. According to the classification standard of Turkish and soil systems, six soil systems, such as clay siliceous mixed acid heat, common aluminum moist embryonic soil, and so on, were established. Eight soil systems, such as 43-CS18, etc., were established. The practice shows that the current classification standard of Turkish soil system is suitable for the classification of soil base classification unit. Compared with the results of soil genesis classification, the results of soil systematic classification can reflect the difference of soil properties of granite parent material development in eastern Hunan more quantitatively, and then objectively reflect the difference of soil development stage and soil type.
