摘要
通过改进由二室模型所建立的人工林地土壤水分垂直变化的数学模型,并选取2002-2006年宁夏固原上黄生态试验站人工柠条林地观测所得的土壤水分数据对改进模型进行验证。结果表明,改进模型较原模型能更好地反映不同条件下土壤水分的垂直变化特点,且模型在土壤水资源的可持续利用中有较好的应用价值。
A modified mathematical model of soil water was established and the soil water data were measured in the caragana shrubland at Shanghuang Eco-experiment Station during the five years from 2002 to 2006, then they were used to examine the mathematical model of soil water. The results showed that the modified vertical variation model could better describe the variation characteristics of soil moisture under different situations, suggesting that the improved model of soil water had good application value in the sustainable use of soil water resources.
