| 1. | Water engineering of agricultural lands - terms - part 3 : soil science , soil taxonomy , soil investigation
农业水利工程.术语.第3部分:土壤学土壤分类学和土 |
| 2. | Design of automatic soil identification and classification system from remote sensing data based on soil taxonomy
基于土壤系统分类的土壤遥感自动识别分类系统的设计 |
| 3. | In chinese soil taxonomy the soils of the tropical and subtropical china could be grouped into ferrisols and ferralisols
据此，这一区域的地带性土壤主要是富铁土和铁铝土。 |
| 4. | The main results are shown as follows : 1 . establishment and application of the database system of soil taxonomy for hubei province
1湖北省土壤系统分类数据库系统的建立与应用1 |
| 5. | Since 1980s ， the soil taxonomy based on by diagnostic horizons and characteristics of soils was introduced into chinese soil classification
这一分类的特点是根据土壤诊断层和诊断特性划分土壤类型。 |
| 6. | 4 . the result of soil taxonomy consist fundamentally with that of the genetic classification and the boundaries roughly identify with each other , indicating the taxonomic classification is based on the genesis theory and the two classification system are touched tightly
土壤系统分类与地理发生分类的分类结果是基本吻合的，分布界线也大体一致，说明系统分类是以土壤发生学理论为基础的，两种分类体系有密切联系。 |
| 7. | The comparability and otherness are coexist in the text of soil taxonomy with numerical analysis method , which indicates that soil taxonomy is a kind of more objective and more scientific method for soil classification , and the numerical analysis can be considered as the measure to test the soil taxonomy
用数值分析方法检验系统分类相似性与差异性共存，表明系统分类是一种更客观、更科学的分类方法，数值分析可作为检验系统分类结果的手段。 |
| 8. | Referencing between the genetic soil classification of china ( gscc ) and the chinese soil taxonomy ( cst ) for gscc - high - mountain - soils was conducted and their quantitative and spatial distribution characteristics within cst were studied , based on the 1 : 1m soil database of china , which consists of 3 parts , 1 : 1m digital soil map , soils profiles attribution database and soil reference system of china
摘要本文利用最新建立的1 : 100万中国土壤数据库，研究了我国发生分类高山土与中国土壤系统分类的参比及其在系统分类下的空间分布和数量特徵。 |
| 9. | 3 ) indexs of soil series taxonomy and retrieval orders : a ) soil structure : the classification was based on the soil profile and " b " horizon differentiation . b ) texture style . c ) organic substance : according to four levels 20 . 1 - 30 . 0 , 10 . 1 - 20 . 0 , 6 . 1 - 10 . 0 , < 6 . 0 ( g / kg ) 4 ) according to the standard of chinese soil taxonomy and this study , 17 soil swatches were divided into 14 soil series . among which , 9 belonged to cambic order , the order 7 belonged to entic order
土壤有机质状况：按照土壤有机质分级指标，结合供试土壤有机质状况，按20 . 1 ? 30 . 0 、 10 . 1 ? 20 . 0 、 6 . 1 ? 10 . 0 、 6 . 0 ( g kg )四个级别划分土系( 4 )按照系统分类统一标准及本研究建立的土系划分指标和检索顺序，对照供试土壤的理化性质进行检索， 17个供试土壤共划分为14个土系，其中9个属于雏形土纲， 5个属于新成土纲。 |
| 10. | Nowdays , the international majority of soil classification is the soil taxonomy , which is based on the diagnostic horizon and diagnostic characteristics , and characterized by quantification . the tendency of soil classification in the world is quantification , standardization and intemationalization . the study of chinese soil taxonomy has achieved great phase outcome - chinese soil taxonomy
当前，以诊断层和诊断特性为基础、定量化为特点的土壤系统分类是国际土壤分类的主流，定量化、标准化和统一化已成为国际土壤分类发展的大趋势，我国的土壤系统分类研究也取得了阶段性成果? ?中国土壤系统分类。 |
