土壤检测的传感器技术发展现状与展望
摘 要：近数十年来，土壤性态空间变化监测和定位土壤性态动态监测的传感器技术均有较快的发展。在土壤性态空间变化监测方面，土壤湿度和温度等物理性状与土壤酸碱度、氧化还原电位和盐分等化学性状的传感器技术研究较为成熟，养分和有机质等的传感器技术的研究较为薄弱，而生物学传感器在土壤检测上应用的研究至今仍非常欠缺。在定位土壤性态动态监测方面，已发展有卫星、航空、无人机和地面平台搭载的不同类型传感器，涉及遥感和近地传感二大类技术，但目前遥感和近地传感技术对土壤的监测主要基于经验模型，如何实现精准检测还存在很多关键问题需要研究。随着新工艺与新材料（纳米材料）的运用，土壤检测传感器将向微型化、仿生、智能、多功能化方向发展。

Abstract：In recent decades，the sensor technology for monitoring the spatial and dynamic variations of soil properties has been developed rapidly. In the aspect of monitoring the spatial variation of soil properties，the sensor technologies of physical properties such as soil moisture and temperature and chemical properties such as soil acidity and alkalinity，redox potential and salt were mature，and the sensor technology about soil nutrients and organic matter was weak，while the research about application of biosensor on soil detection was lack. In the field of dynamic monitoring of soil properties，different types of sensors including satellites，aerial vehicles，unmanned aerial vehicles and ground platforms，which related to remote sensing and near-ground sensing，have been developed. However，at present，the monitoring of soil properties by the remote sensing and near-ground sensing technology was mainly based on empirical models. How to achieve accurate detection was still a problem. Key issues need to be studied. With the application of new technology and new materials （nan...
