Examples
- And on such a basis , it is suggested that under the artificial soil order , a new soil type , " engineering disturbed soil " , be established , and based types of disturbance , this type of soil be further divided into engineering heaped soil and engineering sinking soil
最后建议在人工土纲下独立出一土类“工程扰动土类” ，并根据扰动类型的不同，将工程扰动土分为工程堆垫土、工程下陷土。 - 1 . 4 based on the attribute db , the soil classification graphic db is set up by using arc / info cis . the soil order , suborder sketchs and basic classification unit ( series ) sample maps , make the distribution of soil in hubei province clear at a glance
4在属性数据库的基础上，利用arc infogis建立了湖北省土壤分类图形数据库(空间数据库) ，运用计算机编制和输出了全省土壤系统分类土纲、亚纲概图和基层分类单元(土系)样块图，使全省土壤分布状况一目了然。 - 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。 - Trough overlaying of landform , parent material and soil maps , soter unit database is developed . moreover , soter land resource database was established based on soter unit map and climate region map . soter land use database was built based on china land use classification and soter socio - economical database is built base on statistical data
在此基础之上，更新土壤属性生成母质图，进而利用土壤普查资料中的剖面记载与剖面描述将邯郸地区土壤发生分类转换为系统分类，邯郸地区存在雏形土、新成土、有机土、人为土、盐成土五个土纲十三个土类二十一个亚类。 - 1 . 3 under inquiring , inspecting , contrasting and analysing the information of soil basis ( series ) classification , the soil taxonomy of hubei province is established . and the soil for hubei province are divided into 10 soil orders , 16 suborders , 35 great groups and 54 subgroups , contrasted with international soil systematics such as the american soil taxonomy , the fao world soil map legend unit and the world soil resource reference basis , any sort of soil in hubei province has each own apprepriated places . this conveniently joins the soil taxonomy and the achievements in soil research in hubei with the international convention and realizes the international communication and application
3通过全省土壤基层分类(土系)信息的查询检索和分析比较，拟定了湖北省土壤系统分类，将全省土壤划分为10个土纲、 16个亚纲、 35个土类、 54个亚类，并与美国土壤系统分类、 fao世界土壤图例单元和世界土壤资源参比基础等国际土壤分类系统进行对比，确定其相应位置，便于湖北省土壤分类和土壤研究成果与国际接轨，实现我国土壤信息在国际上交流和应用。
