气候变化与土壤湿度关系的研究进展

在分析气候变化与土壤湿度关系研究现状的基础上,综述了该研究的进展。首先,描述了用数值模拟方法研究气候变化与土壤湿度之间关系的现状;论述了该研究取得的成果和需要进一步研究的问题;其次,简要总结了目前研究仍显薄弱的资料诊断分析工作及取得的成果。土壤湿度的监测与预报是制定合理的灌溉制度从而实现适时适量灌溉的基础,因此本文对气候变化条件下土壤湿度变化趋势的研究及节水灌溉(特别是干旱地区)具有重要的意义。

Progress in the Research on the Relationship between Climate Change and Soil Moisture

On the base of analysis about the current research situation of the relationship between climate change and soil moisture,the research progress was summarized in this paper.First,the current situation in the numerical modeling of the relationship between climate change and soil moisture was depicted.Furthermore,research achievements and some problems were discoursed.Secondly,the works,which is less than the numerical modeling and related to the analyses of the data of climate change and soil moisture,were summed up.The determination of rational irrigation systems and achievement of irrigating timely and properly are based on the monitoring and prediction of soil moisture,so the results of this paper has important significance for the research of trend of soil moisture with the change of climate and water-saving irrigation(especially in arid area).
