补充资料：栗钙土
| 栗钙土 chestnut soil 发育于温带半干旱草原植被下的土壤。上部呈栗色，下部有菌丝状或斑块状或网纹状的钙积层。主要分布于欧洲大陆温带草原和北美温带草原地区，中国主要分布于内蒙古境内。成土过程有明显的有机质和碳酸钙聚积，碳酸钙富集过程相当明显。土壤溶液为盐基所饱和，呈弱碱性反应，全剖面pH在7.2～9.0之间，上部稍低，下部偏高。质地较轻，颗粒组成中以细砂占绝对优势。植被由旱生多年生草本植物组成，主要是丛生禾草，走茎类和根茎类禾草、旱生类杂草及草原灌木与半灌木等也有存在。中国栗钙土植被，无论是种类、组成、生长高度、覆盖度或产量，都是从东向西递减趋势。根据栗钙土形成条件的差异，分为暗栗钙土、淡栗钙土、栗钙土、草甸栗钙土4个亚类。栗钙土区以发展畜牧业为主，应合理安排草场，分区轮牧，防止草场退化。水分条件较好的地方，可农、牧结合，营造防护林带网，建立人工饲草饲料带，增施肥料，发展灌溉，同时注意防止土壤次生盐化。
