摘要
土壤含水量是土壤学和农业节水技术研究的重要领域和热门课题,通过分析相关文献,将土壤水分测定方法从研究手段和范围(尺度)上划分为三大类:取样—定位测量法、遥感监测法、模型模拟法。经过对已发表土壤水分测定方法相关文献的统计调查和检索,依据文献数量、文献引用率和关键词频度,得出取样—定位测定法是当前土壤水分的主要测定方法,遥感监测法是未来土壤水分测定方法的发展趋势和方向,模型模拟法具有理论探索和研究的价值。
Soil water content is an important field and hot topic in soil science and agricultural water -saving technology research. By analyzing literatures concerned, soil moisture determination methods are divided into three categories: sampling- location measurement method, remote sensing monitoring method, and model simulation method. According to statistical investigation on quantity of literatures, citation index and the fre- quency of keywords, we concluded that the sampling - location method was the main method to measure soil moisture, and the remote sensing monitoring method was the trend of the soil moisture measurement method in the future. The model simulation method also had a theoretical exploration and research value.
