以土壤物理学原理为指导，充分利用土壤基本物理性质，提出一种通过调整土壤剖面的分层组合方式，达到 调控水土过程的技术，命名为人工分层配土（artificially?layered?soil，ALS）工程。为验证人工分层配土工程在水土 调控方面的作用，开展室内积水入渗试验、植被蒸散发试验和野外干旱区土壤水分观测试验。结果表明：室内试 验中，通过调整土壤剖面结构，人工分层配土显著提高了土壤的入渗能力，初始入渗速率提高 3 倍以上，平均入渗 速率提高 67.57%，土壤累计入渗量增加 47.14%，同时降低了表层土壤含水量，减少 38.39% 土壤的无效蒸发量； 野外试验中，分层配土处理组土壤含水量主要储存在地表下 31~50cm 处，而野外原状土土壤含水量主要位于表层 土壤，且相较于原状土壤，人工分层配土耗水量减少 13.32%，耗水速率降低 12.90%。因此，人工分层配土工程实 现了水土调控的目的，对干旱区水土资源调控和荒漠化防治具有重要的意义。
