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。
The existing moisture content prediction models and soil moisture detection techniques are briefly analyzed and their respective characteristics are summarized. It is found that the existing soil moisture measurement technologies need to be improved at the cost-benefit level, and the various moisture content prediction models have more restrictions and are not yet more general and accurate Mature model, the current hot research in this area abroad focuses on “3S ” technology, the technology level is more mature, it is worth learning from. The prospect of soil moisture monitoring and forecasting technology is prospected.
