| 风沙土 aeolian sandy soil 发育于风成沙性母质的土壤。主要特征是土壤矿质部分几乎全由细砂颗粒组成，剖面层次分化不明显，风蚀严重，土壤处于幼年阶段。主要分布于干旱少雨、昼夜温差大和多沙暴的地区，包括世界各大洲的沙漠、草原和半荒漠草原地带。中国主要分布在北纬36°～49°之间的干旱和半干旱地区。风沙土的形成过程与流动沙性母质上自然植被的出现、繁衍和演变紧密相关，当由流动性沙性母质构成的沙丘上出现稀疏的植物时，风沙土的成土过程即告开始。风沙土质地粗，细砂粒占土壤矿质部分重量的80％～90％以上，土壤表层多为干沙层，有机质含量低，有盐分和碳酸钙的积聚。根据植被生长疏密和沙性母质流动性大小可分为3个亚类：①流动风沙土。成土过程微弱，风蚀严重，植物难定居。②半固定风沙土，随流动风沙土着生植物的增多，覆盖增大，风蚀作用和缓，土壤表面变紧实并出现薄层结皮，流动性变小，而呈半固定状态。土壤有机质有所增加。③固定风沙土，除有沙生植物外，还掺入一些地带性植物种，地表结皮增厚，沙面更紧实，剖面分化明显，有团块状结构出现，抗风能力增强，土壤理化性质变化明显。改良风沙土要制止风沙土流动，主要措施是：保护自然植被，建立人工绿色带，覆盖风沙土表面，增施有机肥、种植豆科绿肥，利用化学固沙材料增加风沙土颗粒的固结能力、以减缓风沙土的流动性，有水利条件的可引水拉砂、阻砂、灌淤。改变面貌的关键是发展灌溉业。 |
