摘要
传统的土壤采样和实验室分析方法往往工作量大、前处理复杂、测定周期长、时效差、费用高,因此,迫切需要寻找快速、准确的土壤多参数检测方法,以实现多尺度土壤属性数据的快速获取与更新。系统梳理了便携式X射线荧光光谱(PXRF)、可见光-近红外反射光谱(Vis-NIR)、激光诱导击穿光谱(LIBS)和电弧发射光谱(AES)等光谱技术的原理、特点以及在土壤多参数快速检测中的应用及其研究进展。提出,未来在提高现有土壤多参数光谱检测精度和适用性的基础上,应结合ICP-MS等传统实验室方法,综合应用多种光谱技术以及化学计量学、现代信息技术和空间分析技术等,实现区域多种土壤属性的快速获取与实时监测,以满足我国当前土壤多参数、高精度快速检测及土壤质量精细化管理的需要。
There are many disadvantages in traditional soil sampling and laboratory analysis,including large workload,complicated pretreatment,time-consuming,low time efficiency and high cost. Thus it’s very urgent to find quick and accurate method for soil multi-parameter rapid detection in order to quickly acquire and update the multi-scale soil parameters. In this paper,the principles and characteristics of portable X-ray fluorescence spectroscopy( PXRF),visible and near infrared reflectance spectroscopy(Vis-NIR),laser-induced breakdown spectroscopy( LIBS) and arc emission spectroscopy(AES) have been systematically reviewed,as well as their applications in soil multi-parameter rapid detection and their research progress. To satisfy the actual needs of high precision and rapid detection of soil multi-parameters and delicacy management of soil quality of our country,we suggest,on the basis of improving the existing soil parameter spectrum detection precision and applicability,that realize the fast acquisition and realtime detection of regional soil multi-parameters by combining with ICP-MS and many other traditional lab methods validation,and integrating with the application of different spectroscopic technologies,chemical metrology,modern information technology and spatial analysis technology.
