摘　　要：针对《第三次全国土壤普查暂行土壤分类系统(试行)》(以下简称“《三普试行分类》”)中土类和亚类设置、命名,土属和土种划分依据、命名方式和分类系统表中各级分类单元的排列顺序等问题,提出后续修订建议:高级分类在《三普试行分类》基础上,取消灰化暗棕壤亚类,将灰化棕色针叶林土(漂灰棕色针叶林土)亚类改为漂灰棕色针叶林土亚类,增加漂灰土土类和典型漂灰土、暗漂灰土两个亚类。土属和土种划分依据按一定逻辑顺序尽量列全,对土属和土种用语进一步规范化并对每一个用语作简要说明;进一步对部分土属的命名方式加以说明;每一个土属下的土种划分指标依实际情况确定;在土种连续命名时,根据选用指标及其等级或类别排列顺序以对应规范化用语连续命名,最后接土属名称;土种简名前可加地名以避免异土同名。在土壤分类系统表中,《三普试行分类》中的高级分类单元,除了在灰化土土类前增加漂灰土土类及其亚类,新增的菜园土土类及其亚类排在灌耕土亚纲中灌漠土土类之后,人为工程土亚纲及其土类和亚类排列在灌耕土亚纲之后,其余排列顺序不变,但土属和土种需按拟定的指标及其等级或类别依次排列,避免出现同名的土属和土种。In response to issues related to the forming and defining of soil groups and subgroups,differentiae and names of soil genus and species,and the list sequence of soil taxa at all levels in the Interim Soil Classification System for the Third National Soil Survey(on Trial),following suggestions are proposed:based on the Interim Soil Classification System for the Third National Soil Survey(on Trial),cancel the Podzolic Dark-brown Earths,change the name of“Podzolic Gray Brown Coniferous Forest Soils(Bleached Podzolic Brown Coniferous Forest Soils)”to“Bleached Podzolic Brown Coniferous Forest Soils”,and add the group of Bleached Podzolic Soils,and the subgroups of Typical Bleached Podzolic Soils and Dark Bleached Podzolic Soils.According to a logical order,the differentiae components and their classes to distinguish and name soil genus and soil species should be listed as comprehensively as possible.The names of differentiae components and their classes should be further standardized and briefly explained.The naming method of some soil genus should be further explained in detail.The differentiae components of each soil species should be determined according to the actual situation.When naming soil species consecutively,corresponding standardized classes names of the differentiae components should be used continuously according to the selected differentiae components.Finally,the name of soil genus should be connected to the lasted class name of the differentiae component to avoid confusion among relevant personnel in distinguishing higher-level soil categories.The simple name of soil species can be abbreviated with an address to avoid having the same name in different soil types.In the table of soil classification system,the list sequence of higher categories should be consistent with the Interim Soil Classification System for the Third National Soil Census(on Trial),except for adding Bleached Podzolic Soils and its subgroup before Podzolic Soils,the newly established Hortisols and its subgroup after the Irriga
