The fifteen soil orders十五个土纲

New Zealand Soil Classification · orders in the sequence the key tests them, not in alphabetical order

新西兰土壤分类 · 按检索表的检索顺序排列,而非按字母顺序

The fifteen orders are the top level of the New Zealand Soil Classification. Below them sit 74 groups, and below those 299 subgroups. A soil belongs to the first order in this list whose requirements it meets — which is why Brown Soils, the commonest soils in the country, come twelfth.

十五个土纲是新西兰土壤分类的最高一级,其下有 74 个土类,再下有 299 个亚类。一个土壤归属于本列表中第一个满足其判据的土纲——正因如此,全国最常见的 Brown Soils 反而排在第十二位。

The key sequence检索顺序

Start at the top and work down. Everything from Gley Soils onwards is worded "Other soils that…", so once a soil meets an order's requirements the orders below it are never tested.

从最上面一条开始,逐条向下。自 Gley Soils 起,每一条的措辞都是「其余符合……的土壤」,所以一旦某个土壤满足了某个土纲的判据,它下面的土纲就不再检索了。

Order concepts, key criteria and group keys are paraphrased from the New Zealand Soil Classification (Hewitt & NZSC Working Group, version 3.0), published by Manaaki Whenua — Landcare Research. Where a paraphrase and the published definition disagree, the published definition governs. Field clues, confusions and land-use notes are the Soil Protection Group's own. Area percentages are indicative national figures and are rounded.

各土纲的概念、检索判据与土类检索表,系转述自 Manaaki Whenua — Landcare Research 出版的《新西兰土壤分类》(Hewitt 与 NZSC 工作组,3.0 版)。凡转述与已发表定义不一致之处,以已发表的定义为准。野外识别要点、易混淆之处与土地利用说明为土壤保护研究组自撰。面积百分比为全国概数,已作取整。 土纲与土类的正式名称保留英文原名:新西兰土壤分类尚无通行的中文译名,自行拟译会造成误导。
