| Outline of Final Research Achievements |
This study examined availability of VIS-NIR spectral images to distinguish live fine roots from dead fine roots obtained from a 35-year-old Chamaecyparis obtusa stand. The live-dead classification was improved when training data was prepared using both of 1st and higher order roots. Furthermore, classification accuracy was improved by using VIS-NIR reflectance images including two NIR bands. In addition, fine root production and turnover rates in the same C. obtusa stand were estimated to be 45 g m-2 y-1 and 0.34 yr-1, respectively.
