| Research Abstract |
In order to ask for an exact forest structure and the exact biomass by ground investigation, it is required to measure the biomass for every organ of trees and the stratified biomass, but for that, great time and a great labor are needed. On the other hand, there is a possibility of enough that the information about the three-dimensional structure of forests, such as a diameter of a tree at breast-height of trees, can be presumed with high precision by non-contact by using the three-dimensional measurement data of the forest by Scanning Lidar equipment. It aimed at developing the technique of presuming the three-dimensional structure of a forest from the data which carried out three-dimensional measurement of the inside of a forest using Scanning Lidar in this research. Firstly, biometric based estimates of the production and death rates in forest ecosystem are investigated in the scope of carbon balance measurement on the ground. On the other hand, the analysis technique for acquiring the three-dimensional structure of the forest by remote sensing was considered. By the land cover classification using remotely sensed data, the forest ecosystem in the area at the foot of Mt.Fuji is classified into five categories, and the biomass of each ecosystem was estimated. As a result, the total biomass of the whole forest ecosystem in 2002 in the region was estimated to be 0.3x10^6 tC, and the biomass per unit area was presumed to be 97 tC/ha.
