| 摘 要： | 植物根系传统研究方法的局限性迫切需要寻求一种无损性的根系探测技术.基于无损性探测的特点,探地雷达已被证明是一种能够应用于根系探测的潜在工具.对探地雷达探测原理及其在植物根系形态绘图、根径大小和生物量测量等几个方面中的应用研究进行了综述,阐述了该方法的优势和应该注意的问题.根系形态分布探测需要提高雷达的发射频率和保持足够小的扫描间距;在估计植物根系大小和生物量方面主要依赖于有效的、能够反映相关特征的雷达探测信息参数的提取,同时还需要高级的数值分析和数据处理技术的支持. |

| Abstract: | With the recognition of the important functions of roots in ecosystems,root-related parameters such as root size,biomass,distribution,structure and 3D architecture are urgently required for a better understanding of root functions,biogeochemical cycles,and various aspects of global change.Traditional methods for measuring roots are labor intensive and destructive in nature,limiting quantitative and repeated assessments in long-term research on roots.Ground-Penetrating Radar(GPR) offers a nondestructive meas... |
| Keywords: | Ground Penetrating Radar Plant root systems Nondestructive detection Plant root system mapping Root biomass. |
