补充资料：漠土
| 漠土 desert soil 发育于干旱少雨、植被稀疏的荒漠地区的土壤。其主要特征是：土层薄，石砾多，石灰、石膏及水溶盐类含量高。广泛分布于亚洲、非洲、大洋洲、南美洲和北美洲。中国西北部的温带荒漠区，包括内蒙古、宁夏、青海、甘肃和新疆等省(自治区)也有存在。漠土地区降水少、蒸发量大，植被覆盖稀疏、生物作用微弱，土壤有机质积累作用不明显。中国境内的漠土根据气温或干旱程度的不同可分为灰漠土、棕漠土、灰棕漠土3个亚类。由于中国漠土地区处于温带及暖温带，日照长、热量足，只要有水源灌溉和设施并注意防治干旱、风沙和盐碱危害，可以建成肥沃的绿洲和优越的草场。其中灰漠土地区可进行农业生产，棕漠土和灰棕漠土地区则宜放牧骆驼等。
