Principles and errors of measuring infiltrability with horizontal soil column and Green-Ampt model;
用水平土柱与Green-Ampt模型方法测量土壤入渗性能的原理与误差
The processes of water diffusion in non-saturated soils and the relationship between water diffusion rates and water contents were simulated by horizontal soil columns from saline-alkalined wetland in Xianghai National Natural Reserve.
运用水平土柱入渗法模拟研究了盐碱化湿地土壤的水分扩散过程以及水分扩散率和土壤含水量之间的关系,结果表明:盐碱化可降低土壤的水分渗透性能,湿地10～20cm内土层水分渗透速度较其它两层小得多,下部土壤层次的水分扩散率高于上部土壤层,湿地土壤水扩散率随土壤含水量的增加呈指数增长变化的趋势,且表层土壤的增长曲线相对较陡。
This paper made a systematic researches on the determination on the level of soil andwater loss in leveling area of development and construction(not being adopted the measurement of soil and water conservation).
对开发建设平土区（未采取水保措施）的水土流失等级划分及其侵蚀模数确定进行了较为系统的研究，其等级划分标准与传统的农林水土保持截然不同。
