会议专题介绍

利用简易工具监测土壤水分变得日益可行与成熟,这使得大量的田间试验研究成为可能,从而便于了解环境变量和土壤水分之间的关系。此外,气候变化研究也促进了该领域知识的发展。目前,全球已安装许多陆地关键带观测站,在局部和流域尺度上也已获取大量新的土壤水分信息。

我们诚邀土壤水分监测相关研究的投稿,主要包括土壤水分,以及土壤水分时空变异的影响研究。

目前,在理解土壤水分在环境中的作用,以及土壤水分与其它因子(如土壤和空气温度、空气湿度、碳氮有效性等)间的交互关系上,仍存在许多问题。同时,研究土壤水分的时空变异性的结构也极有必要,如不同尺度上土壤水分测量数据的融合。土壤水分通常是在局部尺度上进行测量,但水文地球物理领域则需要在更大尺度上进行土壤水分测定,而微气象测量工具(如涡度相关)则能够对大尺度上的气体和能量通量进行测量。宇宙射线在土壤水分测定中的应用越来越广泛,遥感影像也成为一种能够实现大尺度土壤水分监测的有力工具,因此,土壤水分监测空间尺度的拓展与采样频率的提高成为人们关注的问题。

我们欢迎生物地球科学和土壤科学领域的专家学者参与本分会,进行学术交流和研究分享,例如与土壤水分对碳、氮循环影响,以及对根系和植物生长影响相关的研究。

Session description

The growing possibility of monitoring soil moisture with rather simple tools has allowed to perform many field experiments devoted to understand the links between environmental variables and soil moisture. Also, climate change research has boosted this field of knowledge. Many terrestrial critical zone observatories have been installed, therefore new information both at the local and at the catchment scale is now available.

We invite contributions related to soil moisture monitoring, both finalised to understand the effects of its time and spatial variability, and to studying soil moisture itself.

Many open issues still exist in understanding the role of soil moisture in the environment, in combination with other factors such as soil and air temperature, air humidity, carbon and nitrogen availability, etc. Also, it is necessary the study of the structure of time and spatial variability of soil moisture itself, for example to combine the different scales of measurements. Usually soil moisture is measured at the local scale, but hydrogeophysics allows to have larger scale measurements and micrometeorological tools such as eddy covariance provide even larger scale estimation of gas and energy fluxes. The cosmic ray have increasing applications and the remote sensing images are powerful tools, therefore interesting issues regard the spatial upscaling, and the sampling frequency.

Scientists working both in the biogeosciences, and in soil sciences field are encouraged to participate, for example with study related to the implications of soil moisture on carbon and nitrogen dynamics, as well as on root and plant growth.
