摘　　要：对已有墒情预报模型和土壤水分检测技术进行简单分析,总结了各自特点,发现现有土壤墒情检测技术在性价比层面还需提高,各墒情预报模型所受限制较多,仍没有较为通用、准确成熟模型,目前国外在这方面的热点研究集中于依靠"3S"技术,技术水平更为成熟,值得借鉴。对土壤墒情监测预报技术的前景进行了展望。By collecting and editing the papers and articles on the monitor technology,home and aboard,of the soil moisture prediction,this paper gives us a brief introduction to the existed test technology of the moisture in the soil and the prediction model of the soil moisture.Meanwhile it puts forward the advantages and disadvantages of the prediction model respectively,giving a summary of the soil moisture prediction model both at home and aboard,the existing soil moisture detection technology in the price level needs to improve,the moisture prediction model constraints more,there are not still more common,accurate and sophisticated models,and giving his anticipation of the soil moisture monitor technology in the future.
