补充资料：草甸土
| 草甸土 meadow soil 发育于地势低平、受地下水或潜水的直接浸润并生长草甸植物的土壤。其主要特征是有机质含量较高，腐殖质层较厚，土壤团粒结构较好，水分较充分。分布在世界各地平原地区。中国南方草甸土由于长期耕种，大部分已发展成水稻土和其他耕种类型土壤；北方主要分布在东北三江平原、松嫩平原、辽河平原及其河沿地区。草甸土的形成有潴育过程和腐殖质积累过程。草甸土有腐殖质层、腐殖质过渡层和潜育层。草甸土可分为暗色草甸土、草甸土、灰色草甸土和林灌草甸土4个亚类。由于草甸土肥力水平较高，生产潜力较大，已广为利用。但在水分过多时易出现湿害或受洪水威胁，有的还受盐碱影响。注意防洪排涝和治盐碱是利用改良的关键。 |
