摘要:

多尺度土壤水信息的精确观测是深刻理解四水转化内涵、积极应对与其密切相关地质灾害的关键。本文介绍了中小尺度和大尺度土壤水常用监测方法的原理、优缺点和适用范围,其中大尺度土壤水监测以遥感直接获得的温度和反射率信息为基础。还进一步介绍了遥感信息的获取方法和技术手段,以及基于上述遥感信息发展出来的干旱观测方法和土壤水分反演模型,并对未来的土壤水观测进行了展望。

Abstract:

Precise observation of soil water content at multi-scales is the key to understanding the transformation among atmospheric water, soil water, surface water and groundwater, and developing adaptive strategies to the geological hazards associated with it. General observation methods and their principles, advantages, disadvantages and adaptations were presented at multi-scales. Specially, soil water observations at large scale were achieved through soil water inversion models based on the remote-sensing information, e.g. temperature, reflectivity and other parameters developed through the combination of temperature and reflectivity. Methods and techniques used to obtain the information were also presented. Future development of soil water observations was discussed.

Key words: soil water content, isotope tracer, remote sensing, river basin, monitoring
